How we assess speech sound difficulties

ByLondon Speech and Feeding
| | | |

If your child is hard to understand, mixes up sounds, or says ‘tat’ instead of ‘cat’, you might be wondering what actually happens at a speech sound assessment. It is a really common question, so I want to walk you through what I do in clinic.

Speech sound difficulties look different in every child. Two children can both struggle with the /K/ sound for completely different reasons. The assessment is how I find out the why, so that therapy targets the right thing from the start. For your child, it mostly feels like playing games and looking at pictures.

Step 1: Listening to sounds

I usually begin with sound awareness. This is your child’s ability to hear, notice and play with the sounds in words.

We might do some rhyming (‘Does cat rhyme with hat?’) or clap out the beats in words, like ba-na-na or el-e-phant. Children usually enjoy this part, and it helps them settle in.

Why start here? Being able to hear and think about sounds is the foundation for saying them clearly. It also supports reading and spelling later on. If a child finds it hard to hear the difference between sounds, that tells me a lot about where their speech difficulties may be coming from.

Step 2: How the mouth moves

Next, I look at oro-motor skills. That simply means how the lips, tongue and jaw look and move.

I might ask your child to copy some movements: a big smile, a kiss, poking their tongue out, or moving it from side to side. I also watch how they manage these movements one after another. I often use my puppet and show how its tongue can move. Before I go and look into a child’s mouth I demonstrate on my puppet how we do this.

This helps me check whether the muscles and movements needed for speech are working as they should. It is one piece of the puzzle, not the whole answer, but it helps me rule things in or out.

Step 3: Vowels

Vowels are the ‘open’ sounds in words, like the sounds in cat, bed, sheep, moon and boat. They are easy to overlook, but they make a huge difference to how clear speech sounds.

I use vowel picture sheets and vowel pictures, and I listen carefully as your child names them. Most children get their vowels right quite early. If vowels are tricky, it can point towards particular types of speech difficulty, so this step really matters.

Step 4: Choosing the right next assessment

By this point I have a good idea of what might be going on. I then choose the assessment that fits your child best.

The CLEAR Phonology Screen (or an informal phonology screen).

Your child names a set of pictures, and I write down exactly how they say each word. This shows me which sounds they can say, which ones they swap, and any patterns. For example, some children leave off the ends of words (‘ca’ for ‘cat’). Others replace all back sounds with front sounds (‘tar’ for ‘car’). It also picks up difficulties with single sounds, such as a lisp on /S/.

The Nuffield Dyspraxia Programme assessment.

If I think your child might have difficulty planning and sequencing the movements for speech, I use this instead or as well as. This can be the case with childhood apraxia of speech, sometimes called verbal dyspraxia. Your child names pictures and copies words that gradually get longer. I am looking at how well they can link sounds and syllables together smoothly, and how consistent their speech is.

I do not use every test with every child. Choosing the right one means the assessment is focused, and it does not tire your child out.

What happens afterwards

Once the assessment is done, I look closely at everything I have noted. I then talk you through what I found, in plain language. Together we agree clear goals for therapy and the order in which to work on them.

You will also get ideas for simple games and activities to do at home. Short, regular practice at home makes a real difference to progress.

A few things parents often ask

Does my child need to prepare? No. Just come as you are. I adapt everything to your child’s age and mood on the day.

What if my child is shy or will not join in? That is completely normal. I take things at your child’s pace, and we can always finish another time.

Can I stay in the room? Yes. Many children feel more relaxed with a parent nearby, and it helps you see what we do. Some children do better on their own and we can discuss this as we go and I get to know you and your child.

Will we need to do homework in between speech sessions? Yes, this is very important. Each week I will give you a couple of activities to do with your child which will help you practise what we do in the therapy room daily, and this is where progress is made!

Worried about your child’s speech?

If you have concerns about how your child is speaking, and assessment gives you clear answers and a plan. Get in touch with me to book an assessment or to ask any questions via my contact form. I look forward to hearing from you.

    Let’s ditch the ‘Fix-It’ approach to autistic play and stimming

    ByLondon Speech and Feeding
    Let’s ditch the 'Fix-It' approach to autistic play and stimming

    December is often presented as a time of perfect, reciprocal play. Children are supposed to be unwrapping toys, sharing, and engaging in imaginative scenarios with family. But for parents of young autistic children, this high-pressure, socially demanding period can often feel like a battleground.

    If you’ve been told to interrupt your child’s stimming, push for eye contact, or force them to play ‘functionally’ with toys, it’s time to take a deep breath. Those traditional approaches are not only stressful—they often miss the point of your child’s communication.

    As a neurodiversity-affirming Speech and Language Therapist, I want to encourage you this December: You are allowed to follow your child’s lead, validate his or her unique interests, and trust that his or her play and movement are profoundly meaningful.

    1. Stimming: not a distraction, but a regulator 💡

    Stimming is short for self-stimulatory behaviour and includes repetitive movements or sounds like hand flapping, humming, rocking, finger flicking, or repeating phrases (called echolalia).

    For years, parents were incorrectly advised to block or eliminate these behaviours. The neurodiversity-affirming view tells us the exact opposite: Stimming is a vital and essential tool for your child’s self-regulation.

    Think of stimming as an internal volume dial:

    • Too loud/overwhelmed: Your child may stim to reduce incoming sensory input (e.g., rocking to ground himself or herself in a busy room).
    • Too quiet/under-stimulated: Your child may stim to increase sensory input and focus (e.g., running back and forth to maintain alertness).

    The shift: validate, don’t block

    Instead of saying, ‘Stop flapping your hands’, try to understand the message behind the movement.

    • Observe: When does the stimming happen? Is it before a meltdown? When your child excited? When your child is bored?
    • Validate: Name the need, not just the behaviour. You might say, ‘I see your body needs to move fast right now. That helps you calm down!’
    • Co-regulate: If the stim is unsafe (e.g., head-banging), help your child find a safer, alternative stim that meets the same sensory need (e.g., pushing hard against a wall, squeezing a stress ball).

    By validating your child’s need to regulate, you are building trust, reducing anxiety, and teaching him or her critical self-awareness.

    2. Autistic play: Meaningful, even if it’s monologue

    The traditional idea of ‘good play’ often involves turn-taking, pretending, and specific toy functions (e.g., pushing a train around a track). When an autistic child spends 30 minutes lining up cars, spinning their wheels, or scripting whole scenes from a favourite movie, it can often be dismissed as non-functional or repetitive.

    In neurodiversity-affirming practice, we recognise that autistic play is authentic play. These activities are crucial for learning, deep focus, and imaginative development.

    • Lining up toys may be an exploration of patterns, visual organisation, and order.
    • Spinning wheels may be a deep interest in cause-and-effect and visual sensory input.
    • Scripting is often a way to process language, regulate emotions, and practise complex social situations in a safe, controlled way.

    Make a change: Join your child’s world, don’t drag them to yours.

    Stop trying to force the ‘right’ way to play. Instead, try these neuro-affirming strategies:

    1. Be a co-regulator, not a director: If your child is lining up cars, sit down next to him or her. Instead of moving a car, try handing him or her another car to line up. Focus on the shared interest rather than forcing interaction.
    2. Narrate (don’t question): Avoid constantly asking, ‘What are you doing?’ or ‘What does this car say?’ This puts pressure on your child to perform. Instead, narrate your observations using his or her interest: ‘I see you made a long, straight line of red cars. Look at all the wheels spinning!’
    3. Validate the interest: Show genuine appreciation for your child’s focus. ‘Wow, you know so much about how magnets stick together! That’s incredible.’

    3. The communication revolution: Honouring gestalt language processing 

    Many young autistic children communicate in ways that don’t fit the traditional model of building language word-by-word. Many use Gestalt Language Processing (GLP).

    A gestalt language processor learns language in chunks or scripts (e.g., ‘what’s-in-there?’ or ‘ready-go!’). These chunks (or gestalts) are not random; they are often tied to an emotional memory or meaning. Over time, the child breaks down these big chunks into individual words then learns to recombine those words creatively.

    If your child repeats movie phrases or whole sentences that seem unrelated, he or she is likely a gestalt language processor!

    Affirm the script, then model something useful.

    1. Affirm the script: When your child says a script, respond to the meaning or emotion behind it, not the literal words. If he or she says, ‘We’re going to need a bigger boat’, and he or she is looking at a messy toy pile, he or she may be trying to express overwhelm or a need for help. You can affirm: ‘That pile is too big! I can help you move it.’
    2. Model new ‘mix and match’ scripts: To help your child move from whole scripts to single words, you can model shorter, slightly changed versions of the script, also called ‘mitigated gestalts’. If they say, ‘I want to go home now’, you might model, ‘Let’s go home, now’ or ‘I wanna go home’.

    By honouring your child’s communication style, you validate his or her experience and naturally support his or her path to language development—a core part of neurodiversity-affirming SLT.

    Your December gift to your little one:

    This December, stop trying to make your child fit into a neurotypical box. Instead, make your home a safe space where he or she can be his or her authentic selves.

    Prioritise regulation and connection over compliance.

    Trust that when your child is regulated, his or her communication, learning, and engagement will flourish naturally. This is the true gift of neurodiversity-affirming practice.

    Download and print my neuro-affirming quick reference guide and keep this guide handy on your fridge and/or in your child’s play area for a quick reminder to prioritise connection over conformity.

    Following your child’s lead: A playful path to AAC success

    ByLondon Speech and Feeding

    Unlocking playtime: A guide to child-led learning

    Does your child struggle to focus on toys or activities? Do they dart away as soon as you approach? You’re not alone!

    The key to unlocking your child’s potential lies in following their lead. Let them guide the play session, and watch their engagement and focus soar.

    Why Child-Led Play Works:

    • Empowerment: Children feel in control, sparking their curiosity and motivation.
    • Focused attention: They’ll stay engaged with activities for longer periods.
    • Reduced frustration: By stepping back and observing, you eliminate the pressure and stress that often comes with directed play.

    How to Implement Child-Led Play:

    1. Prepare the environment: Set out a limited selection of engaging toys.
    2. Observe and wait: Sit back, watch, and listen to your child’s interests.
    3. Embrace the moment: Resist the urge to direct or question; simply enjoy the process.

    Remember: This simple approach can transform playtime and support your child’s development. Give it a try for a week and see the difference!

    #OWLing #hanenmorethanwords

    Observe, Wait, Listen. It’s a powerful formula for unlocking your child’s potential.

    You will likely see:

    • Your child will stay put with any toy for longer whilst you are near them.
    • Your child will tolerate you being nearby and he/she won’t move away.
    • Your child will start giving you brief glances of enjoyment, or perhaps they will hand things to you, or they might take your hand and lead it to something that needs opening etc.
    • In other words, you will see that there suddenly is JOINT PLAY. Yes, granted it may not be according to your adult agenda, but there will be more togetherness than there was before. And this is the START of communication and social engagement.

    USE Core words and a coreboard — to help your child understand the power of words

    Core words are the building blocks of communication. Try using a coreboard like the one below, they are versatile and can be used in countless ways. By modelling these words naturally during play, you expose your child to their meaning and function in context. This approach is far more effective than isolated drill and practice, more powerful than flashcards!

    Using AAC coreboard

    A Winning Combination

    Combining child-led play and AAC modelling creates a magic effect. To summarise:

    • Increased engagement: When you follow your child’s lead, they are more likely to be engaged and receptive to learning. This creates optimal conditions for introducing AAC core words.
    • Natural learning: By modelling AAC core words in the context of play, you help your child understand their meaning and purpose naturally. This fosters generalisation and spontaneous use.
    • Building relationships: Shared play experiences strengthen the bond between you and your child. This trust and connection are essential for successful communication.
    • Reduced pressure: Modelling AAC core words without expectation removes the pressure to produce language. This allows your child to explore communication at their own pace.
    • Expanded vocabulary: As your child becomes more comfortable with AAC, they will begin to incorporate core words into their own communication. This leads to vocabulary growth and increased independence.

    Practical Tips

    • Observe and respond: Pay close attention to your child’s interests and actions. Respond to their cues with enthusiasm and support.
    • Keep it simple: Start with a few core words and gradually introduce new ones as your child’s skills develop.
    • Be patient: Language learning takes time. Celebrate small successes and avoid frustration.
    • Have fun: Remember, play is supposed to be enjoyable for both you and your child. Relax and have fun together!

    Example:

    Photo by lemonlenz

    Let’s say your child is playing with a pop-up toy like you see me do in the above photograph. Here, I followed my child’s lead by waiting to see what she wanted to do with the toy. You are now OWLING! (Observe Wait and Listen)

    Once I noticed that there was repetitive opening of the flaps going on I then pointed to OPEN and MORE on the board, as I said: ‘let’s OPEN this one’ / let’s see MORE animals’ / ‘MORE cow! it says moo!’ ‘OPEN another one’ and so on.

    Important to know, we are not expecting our child to respond verbally or with AAC, but we are providing language input and demonstrating how these words can be used with enthusiasm.

    Naturally in time your child will look at the board and at your pointing and they will eventually want to copy you!

    By incorporating these strategies into your daily interactions, you can create a supportive environment that fosters language development and communication growth.  If you would like more guidance please get in touch and book in for a consultation, some individual therapy and/ or some parent coaching.

    I look forward to supporting you. Please contact me and let’s see how.

  • Tongue-Tie: A complex issue requiring careful assessment

    ByLondon Speech and Feeding

    Tongue-tie, or ankyloglossia, is a condition where the lingual frenulum, the thin piece of tissue that connects the underside of the tongue to the floor of the mouth, is too short or tight. Tongue-tie is quite common in babies and is often not detected after birth. Tongue-tie can lead to a difficult start with breast feeding as it makes it very difficult for the baby to latch effectively.

    In my clinical experience as a feeding therapist, I have seen many babies who were not able to latch well due to the frenulum being tight. In many cases an experienced feeding speech therapist/lactation consultant can really make a difference and help a new mum to latch the baby even though the tongue is tethered to the floor of the baby’s mouth. In some cases the frenulum can be divided and once this has been done, in some cases, feeding improves immediately or soon after the division. But this is not always the case. I have seen several babies who have had as many as four tongue-tie divisions and feeding was still difficult.

    It is important to say that while tongue-tie can sometimes impact speech and feeding, it’s important to note that it’s not always the root cause of these difficulties. In recent years, there has been a surge of interest in tongue-tie division surgeries, with some cases being unnecessary. It’s crucial to understand the complexities of tongue-tie and the role of speech therapy in addressing related challenges.

    The impact of tongue-tie on speech and feeding

    When tongue-tie is severe, it can interfere with the tongue’s ability to move freely, affecting speech production and swallowing. Some common speech and feeding difficulties associated with tongue-tie include:

    • Feeding difficulties: Challenges with sucking, chewing, and swallowing.
    • Drooling: Excessive drooling due to difficulty controlling saliva.
    • Speech problems: Difficulty producing certain sounds, such as /l/, /r/, /t/, /s/ and /d/.

    The importance of comprehensive assessment

    Before considering any surgical intervention for tongue-tie, it’s essential to undergo a thorough evaluation by a qualified speech-language therapist (SLT). An SLT can assess the severity of the tongue-tie, its impact on speech and feeding, and determine if surgery is necessary.

    • Functional assessment: The SLT will assess the tongue’s range of motion, its impact on speech sounds, and the child’s overall oral motor skills.
    • Feeding evaluation: The SLT will observe the child’s feeding patterns and identify any difficulties related to tongue-tie.
    • Differential diagnosis: The SLT will rule out other potential causes of speech and feeding difficulties, such as apraxia of speech, dysarthria, or sensory processing disorders.

    The role of speech therapy

    Even in cases where tongue-tie is present, speech therapy can often be highly effective in addressing speech and feeding difficulties. Here’s how speech therapy can help:

    • Articulation therapy: Targeting specific speech sounds that may be affected by tongue-tie.
    • Childhood Apraxia of Speech (CAS): if the diagnosis by the SLT has shown that in fact the child has motor planning difficulties then there are very specific and effective treatment programmes that help with this and can make a real difference over time.
    • Feeding therapy: Strategies to improve swallowing, chewing, and oral-motor skills.
    • Sensory integration: Addressing underlying sensory processing issues that may contribute to feeding difficulties.

    London Speech and Feeding Case Study: The importance of comprehensive assessment

    One of my clients was initially diagnosed with tongue-tie and recommended for surgery at the age of eight years old. His speech had been perceived by parents and teachers as ‘mumbled and unclear’.

    However, after a thorough evaluation, I was able to determine that the child’s primary issue was apraxia of speech, a neurological disorder that affects motor planning for speech. Parents decided to wait with surgery and trust my judgment and we proceeded with weekly intensive speech therapy to address motor planning difficulties around tricky sounds and words. I am delighted to say that the child’s speech has improved significantly, demonstrating the importance of comprehensive assessment and individualised treatment. He is no longer seen as a candidate for an operation, which would have been traumatic for him at his age and, as it turned out, entirely unnecessary.

    Below is a short video clip of my working on the /l/ sound with this child.

    Using the Gingo Puppet from GingoTalk

    Conclusion

    Tongue-tie is a complex issue that requires careful evaluation and individualised treatment. While surgery may certainly be necessary in some cases, it’s essential to consider the potential benefits and risks. Speech therapy can be a highly effective approach for addressing speech and feeding difficulties associated with tongue-tie, even in cases where surgery is still required. By working with a qualified speech-language therapist, parents can ensure that their child receives the best possible care and support.

    Why tongue lateralisation matters: The hidden feeding skill that every toddler needs

    ByLondon Speech and Feeding

    When parents think about feeding milestones, they often focus on what their child is eating. Are they accepting lumps? Will they eat vegetables? Are they managing finger foods?

    However, one of the most important skills happening behind the scenes is something many parents have never heard of: tongue lateralisation.

    Tongue lateralisation simply means the tongue’s ability to move from side to side inside the mouth. Although this sounds like a small movement, it is one of the key building blocks for safe chewing, efficient eating and later speech development.

    As a Speech and Language Therapist specialising in infant feeding, I frequently assess children who have delayed or absent tongue lateralisation. The encouraging news is that this skill can often be developed. But like many areas of development, there is an optimal window during which children learn it most naturally.

    What does the tongue actually do during eating?

    Eating is an incredibly complex process involving the lips, jaw, cheeks, tongue and swallowing muscles all working together.

    For mature chewing, the tongue needs to:

    • move food from the centre of the mouth onto the back gums and molars
    • keep the food positioned while the jaw chews
    • collect scattered pieces of food from around the mouth
    • reform the chewed food into a single cohesive bolus
    • move that bolus safely to the middle of the tongue before swallowing.

    Without good tongue lateralisation, food often stays in the middle or front of the mouth where it cannot be chewed effectively.

    Children may compensate by:

    • swallowing pieces whole
    • mashing food with the front teeth only
    • relying on sucking instead of chewing
    • holding food in their cheeks
    • gagging frequently
    • refusing more challenging textures altogether.

    These children are often described as ‘fussy eaters’, when in reality they may simply lack the oral motor skills needed to manage more advanced textures comfortably.

    When should tongue lateralisation develop?

    Tongue lateralisation begins to emerge during the second half of the first year of life as babies start exploring textured foods.

    Between approximately 6 and 12 months, babies naturally begin learning to move food sideways towards their gums for early chewing. As molars develop during the second year, these movements become more refined and efficient.

    This period represents an important developmental window because babies are biologically programmed to experiment with increasingly varied textures. Repeated opportunities to chew different foods strengthen the tongue, jaw and cheek muscles while building the complex movement patterns needed for mature eating.

    If a child remains on smooth purées or very soft foods for too long, they may miss hundreds of opportunities to practise these essential movements.

    Why does this developmental window matter?

    Like learning to crawl, walk or ride a bicycle, oral motor skills develop through repeated practice.

    Children who do not experience enough chewing opportunities during infancy can sometimes continue to rely on immature sucking and munching patterns well into toddlerhood.

    This does not mean the opportunity is completely lost after infancy. Many toddlers can still learn tongue lateralisation successfully with the right support. However, the longer an immature pattern is used, the more established it becomes, making change more challenging.

    That is why early assessment is so valuable.

    Signs your toddler may have poor tongue lateralisation

    You may notice your child:

    • chews mainly with the front teeth
    • bites but does not chew efficiently
    • keeps food in the centre of the mouth
    • pockets food in the cheeks
    • frequently spits out textured foods
    • gags on lumps
    • prefers soft foods
    • swallows before food has been adequately chewed
    • takes a very long time to finish meals.

    Not every child showing these signs has an oral motor difficulty, but they do warrant further assessment.

    How can we encourage tongue lateralisation?

    The good news is that the tongue learns through experience.

    One of the best ways to encourage side-to-side movement is by offering long, resistive foods that naturally encourage the tongue to move food towards the side gums for chewing. We also call them sometimes HARD MUNCHABLES – they look like on the following image.

    Hard munchablers

    Examples include:

    • mango pits with most of the flesh removed
    • pineapple core strips
    • thick steak strips
    • cooked pork strips
    • peeled celery sticks
    • thick cucumber spears
    • roasted pepper strips
    • corn on the cob cut into manageable rounds
    • dehydrated apple rings
    • large clean cooked rib bones with a little meat remaining for supervised chewing practice.

    These foods are not intended for children to consume large pieces quickly. Instead, they provide resistance that encourages the jaw, cheeks and tongue to work together while giving valuable sensory feedback.

    A simple technique that can help

    Some toddlers struggle because they never naturally move food to the side of their mouths.

    In these cases, placing a long strip of food gently onto the side gums can sometimes trigger the chewing pattern automatically. This gives the tongue an opportunity to experience where chewing should occur.

    This should always be done calmly, with the child sitting upright and under close adult supervision.

    Every child develops differently

    Some children are more likely to experience delayed tongue lateralisation than others.

    This may include children who:

    • remained on purées for an extended period
    • have developmental delays
    • have low muscle tone
    • were born prematurely
    • have significant sensory processing differences
    • have experienced prolonged tube feeding or medical conditions affecting feeding.

    A feeding assessment can identify whether tongue movement, jaw stability, sensory processing or another factor is contributing to the difficulty.

    Early intervention makes a difference

    One of the biggest misconceptions I hear is:

    ‘They’ll grow out of it.’

    Some children do. Others don’t.

    Without intervention, inefficient chewing patterns can persist for years, affecting food variety, mealtime confidence and nutritional intake. In some cases, immature oral motor patterns may also contribute to unclear speech production later on, although feeding and speech skills do not always develop at the same rate.

    The earlier we identify a problem, the easier it usually is to help children develop more mature, efficient chewing patterns.

    Final thoughts

    Tongue lateralisation may not be a term many parents recognise, but it is one of the foundations of successful feeding.

    By offering opportunities to chew a variety of safe textures during infancy, parents help build the complex tongue movements needed for efficient eating throughout childhood.

    If your toddler still struggles with chewing, gags on textured foods, or seems unable to move food around their mouth, don’t simply wait and hope they will outgrow it. A comprehensive feeding assessment can identify exactly where the difficulty lies and provide practical strategies tailored to your child’s needs.

    Sometimes a few small changes at the right time can make a lifetime of difference. Do get in touch with me. I would love to hear from you and help your little one develop good chewing skills and eating habits.

    The great air debate: How different swallowing patterns impact breastfeeding and reflux

    ByLondon Speech and Feeding

    The great air debate

    As a Speech and Language Therapist specialising in infant feeding, I often hear from worried mums describing their breastfed baby’s fussiness. ‘My baby is so burpy and gassy,’ ‘might it be reflux?’ or ‘she just seems uncomfortable after every feed’. While these concerns are incredibly valid and distressing for both baby and mum (and dads!), the underlying cause isn’t always what you might think. Often, the culprit isn’t primarily a digestive issue, but rather a mechanical one: how effectively your baby is managing air during feeding.

    Many parents are told their baby has ‘colic’ or ‘reflux’ and are offered solutions that don’t quite hit the mark because they overlook a fundamental aspect of feeding: the suck-swallow-breathe sequence. Understanding this intricate dance can be the key to unlocking a calmer, happier feeding experience for your baby and you.

    Understanding the suck-swallow-breathe sequence

    Your baby’s mouth, tongue, jaw, and throat muscles work together in a precise rhythm like a beautifully orchestrated symphony. First your baby draws milk, then swallows it, and then takes a breath, all without interruption. This is the ideal suck-swallow-breathe (SSB) sequence.

    When the SSB sequence functions optimally, a baby latches deeply, creates good suction, draws milk, swallows efficiently, and then pauses just long enough to take a gentle breath before the next suck. This smooth, coordinated process minimises the amount of air swallowed.

    However, for various reasons (it could be a shallow latch, oral motor challenges, an uncoordinated suck, or even an overly fast milk flow) this sequence can get a bit out of sync. Instead of a smooth rhythm, you might see:

    • Suck-suck-swallow-gasp!: Too much air pulled in with the swallow.
    • Rapid, shallow sucking followed by gulping: Inefficient milk transfer and air intake.
    • Clicking noises during feeding: Loss of suction, indicating air entry.
    • Frequent detaching and re-latching: Often to ‘catch a breath’ or because of discomfort.

    Each of these patterns can lead to increased air intake.

    The root cause: Air trapping leading to a gassy breastfed baby

    When a baby swallows too much air during a feed, that air must go somewhere. It builds up in the stomach, causing bloating, discomfort, and often leads to the familiar reflux-like symptoms parents describe: arching, spitting up, burping excessively, or simply appearing distressed.

    It’s a common misconception that all gassiness or reflux symptoms in a breastfed baby are due to something in the mother’s diet or a genuine digestive disorder. While these can be factors, as an SLT, we first look at the mechanics of the feed. If a baby is constantly struggling to maintain a seal, sucking inefficiently, or having to gulp to keep up with flow, he or she is inevitably swallowing air. This air then creates pressure, which can push milk back up (silent reflux) or out (visible reflux).

    Think of it like trying to drink through a straw with a hole in it. You’re sucking, but you’re also pulling in air, making it harder to get the liquid and leaving you with more bubbles in your stomach.

    Why mechanical speech therapy assessment is key

    This is where the distinction between a medical diagnosis (true gastro oesophageal reflux disease or GORD) and a functional feeding challenge becomes critical. A paediatrician will assess for medical causes and may prescribe medication to reduce stomach acid. This can be appropriate for severe cases of GORD.

    However, if the primary issue is air being trapped due to a suboptimal suck-swallow pattern, medication only treats the symptom (acid burning) and not the root cause (air intake). This is precisely where a Speech and Language Therapist specialising in infant feeding comes in.

    My role is to meticulously observe and assess your baby’s oral motor skills, latch, tongue function, and the efficiency of their SSB sequence. I look for subtle signs of inefficiency that contribute to excessive air swallowing.

    • Is the tongue elevating correctly to create suction?
    • Is the jaw stable, or is it excessively moving?
    • Is the latch deep enough to prevent air leaks?
    • Can the baby coordinate suck, swallow, and breathe without gasping?

    By identifying these mechanical challenges, I can then implement targeted strategies to improve feeding efficiency and reduce air intake, often leading to a significant reduction in reflux-like symptoms and overall discomfort.

    Strategies to optimise air management during breastfeeding

    The good news is that many babies can learn to feed more efficiently with the right support. Here are some general strategies we might explore:

    1. Optimise latch and position: A deep, asymmetric latch is crucial. Experiment with different positions that allow for a deeper latch and better head/neck alignment, such as laid-back feeding or upright positions.
    2. Paced feeding (even at the breast): If your milk flow is very fast, consider removing your baby from the breast briefly if you hear excessive gulping or see him or her struggling to breathe. This allows him or her to catch up and manage the flow.
    3. Support the jaw and cheeks: Sometimes, gentle support to the baby’s jaw or cheeks can help them maintain a more stable, efficient suck. I can demonstrate specific techniques for this.
    4. Burping effectively: While burping won’t get rid of all swallowed air, upright burping positions and gentle back rubs can help release some of it.
    5. Pre-feed oral preparation: Gentle oral massage or stretches before a feed can sometimes ‘wake up’ the oral muscles and improve coordination.

    Addressing the ‘Great Air Debate’ isn’t about blaming anyone; it’s about empowering parents with a deeper understanding of their baby’s feeding mechanics. By focusing on the how, not just the what, we can often resolve persistent feeding challenges, reduce discomfort, and make breastfeeding a more joyful, peaceful experience for both you and your little one.

    If you suspect your baby’s gassiness or reflux symptoms are related to how they are managing air during feeds, don’t hesitate to reach out for a specialist assessment.

    Could mouth breathing be affecting your child's speech, sleep and development?

    Understanding Orofacial Myofunctional Disorders (OMDs)

    Many parents contact me at London Speech and Feeding because they are worried about their child’s speech. Perhaps their child is difficult to understand, has a persistent lisp, struggles with feeding, snores at night, or always seems to have their mouth open.

    What many families don’t realise is that these concerns may all be connected.

    Increasingly, research and clinical experience are highlighting the important role of Orofacial Myofunctional Health, the way the muscles of the face, mouth, tongue and airway work together to support breathing, eating, sleeping and communication.

    When these muscles are not functioning optimally, children may develop what are known as Orofacial Myofunctional Disorders (OMDs).

    What Is Orofacial Myofunctional Health?

    Orofacial Myofunctional Health refers to the healthy function and coordination of the:

    • lips
    • tongue
    • jaw
    • cheeks
    • facial muscles
    • airway.

    These structures play a vital role in:

    • breathing
    • swallowing
    • chewing
    • speaking
    • facial growth
    • dental development
    • sleep quality.

    When everything is working well, the lips remain gently closed at rest, breathing occurs through the nose, and the tongue rests against the roof of the mouth.

    This seemingly simple posture has a profound influence on how a child’s face, teeth and airway develop.

    What is an Orofacial Myofunctional Disorder?

    An Orofacial Myofunctional Disorder occurs when there is an abnormal pattern of muscle function involving the face, mouth, tongue or airway.

    Children with OMDs may experience difficulties with:

    • speech
    • feeding
    • swallowing
    • sleep
    • breathing
    • dental development
    • facial growth.

    In many cases, these difficulties are linked to chronic mouth breathing.

    Signs your child may have an Orofacial Myofunctional Disorder

    Breathing and sleep signs

    • mouth open at rest
    • mouth breathing during the day
    • snoring
    • noisy breathing
    • restless sleep
    • frequent waking
    • dark circles under the eyes
    • chronic congestion
    • fatigue despite a full night’s sleep.

    Speech signs

    • lisping
    • unclear speech
    • distorted speech sounds
    • difficulty producing certain sounds
    • persistent articulation difficulties
    • reduced speech intelligibility.

    Feeding and swallowing signs

    • picky eating
    • messy eating
    • food remaining in the cheeks
    • gagging easily
    • difficulty chewing
    • long mealtimes
    • tongue thrust swallowing.

    Facial and dental signs

    • narrow palate
    • crowded teeth
    • open bite
    • overbite
    • underbite
    • long face appearance
    • receding chin
    • poor lip seal.

    If several of these signs sound familiar, a comprehensive assessment may be worthwhile.

    Why does mouth breathing matter?

    Many parents assume mouth breathing is simply a habit.

    In reality, mouth breathing is often a symptom that something is preventing efficient nasal breathing.

    Common causes include:

    • enlarged tonsils
    • enlarged adenoids
    • allergies
    • chronic nasal congestion
    • recurrent infections
    • structural airway differences
    • tongue tie
    • prolonged dummy use
    • thumb sucking
    • poor oral posture.

    When nasal breathing becomes difficult, children naturally begin breathing through their mouths.

    Over time, this can affect how the face, jaws and airway develop.

    What does healthy oral posture look like?

    Healthy oral posture is surprisingly simple:

    • lips
      • gently closed
    • tongue
      • resting against the roof of the mouth
    • teeth
      • slightly apart
    • breathing
      • through the nose.

    This posture helps guide healthy jaw growth, facial development and airway formation.

    Think of the tongue as a natural orthodontic support system. When it rests in the correct position, it helps shape the upper jaw and supports healthy facial growth.

    The consequences of chronic mouth breathing

    1. Speech difficulties

    Children who breathe through their mouths often have altered tongue posture and reduced oral stability.

    This can contribute to:

    • lisping
    • distorted sounds
    • reduced speech clarity
    • difficulty learning new speech sounds.

    2. Feeding and swallowing difficulties

    A low tongue posture may affect:

    • chewing efficiency
    • swallowing patterns
    • food management
    • oral motor coordination.

    Many children develop a tongue thrust swallow, where the tongue pushes forward instead of moving efficiently during swallowing.

    3. Poor sleep quality

    Mouth breathing can contribute to:

    • snoring
    • restless sleep
    • frequent waking
    • daytime fatigue
    • reduced concentration.

    Poor sleep can have a significant impact on learning, behaviour and emotional regulation.

    4. Changes to facial growth

    Over time, chronic mouth breathing may influence:

    • jaw development
    • facial proportions
    • dental alignment
    • airway size.

    This can result in:

    • narrow palates
    • crowded teeth
    • long facial appearance
    • increased orthodontic needs.

    5. Oral health concerns

    The nose acts as a natural filter and humidifier.

    When children breathe through their mouths:

    • The mouth becomes dry.
    • Saliva protection is reduced.
    • Risk of tooth decay increases.
    • Gum health may be affected.

    Why this matters for speech therapy

    Speech does not develop in isolation.

    The tongue, lips, jaw and airway work together to support clear communication.

    At London Speech and Feeding, we look beyond speech sounds alone.

    A child who presents with:

    • persistent speech difficulties
    • lisping
    • feeding challenges
    • open mouth posture
    • snoring
    • poor sleep

    may benefit from an assessment that explores underlying orofacial myofunctional factors.

    Addressing these foundations can often support more effective progress in speech and feeding therapy.

    How London Speech and Feeding can help

    A comprehensive assessment may include observation of:

    • breathing patterns
    • lip posture
    • tongue posture
    • swallowing function
    • feeding skills
    • speech sound development
    • sleep concerns
    • oral structures.

    Where appropriate, recommendations may include:

    • orofacial myofunctional therapy
    • speech therapy
    • feeding therapy
    • home programmes
    • ENT referral
    • orthodontic referral
    • collaborative multidisciplinary support.

    The good news

    Orofacial Myofunctional Disorders are often highly treatable when identified early.

    Supporting healthy breathing, tongue posture and oral muscle function can positively influence:

    If your child regularly breathes through their mouth, snores, struggles with speech clarity or has feeding difficulties, a specialist assessment may help identify the underlying cause.

    • speech clarity
    • feeding skills
    • sleep quality
    • facial growth
    • dental development
    • overall wellbeing.

    At London Speech and Feeding, we are passionate about looking beyond symptoms and understanding the whole child. Contact me!

    Sometimes the key to clearer speech starts with a simple question:

    ‘Is my child breathing through their nose?’

    Frequently Asked Questions

    Can mouth breathing cause speech problems?

    Yes. Mouth breathing can alter tongue posture, lip strength and oral stability, which may contribute to articulation difficulties and lisps.

    Should I be worried if my child snores?

    Regular snoring is not considered normal in children and may indicate airway obstruction or sleep-disordered breathing.

    Can enlarged tonsils affect speech?

    Yes. Enlarged tonsils may affect resonance, tongue positioning, swallowing and breathing patterns.

    What age can children be assessed?

    Children of all ages can be assessed if parents have concerns about speech, feeding, breathing or oral development.

    What is Orofacial Myofunctional Therapy?

    Orofacial Myofunctional Therapy focuses on improving breathing patterns, tongue posture, lip seal and oral muscle function to support overall health and development.
