AAC Systems and Speech and Language Development

ByLondon Speech and Feeding
| |

Introduction

I see a lot of minimally speaking or non-verbal children in my practice. Some children are autistic and others are severely challenged with motor planning and some are both. Some children are simply delayed in their spoken language for reasons that we don’t quite know yet.

Regardless of the causes, what is always apparent pretty quickly is that apart from the odd gestures or Makaton signs (mainly ‘more” ‘finished’ and “biscuit) we don’t have a robust alternative for speech in place. Instead, what we often have is a child with lots of frustration and tantrums and some behaviours we really don’t want like: hitting, biting, pushing, grabbing and often throwing… There are others, too many to mention, but we don’t enjoy watching our children in these states. And we are often fearful of what might happen next if we don’t find a way to calm our child.

Fear not

In my work, before I get to offer an alternative means of communication, I often have to work with a fair amount of resistance on the parents’ side as parents tend to feel that allowing such a system into their lives will prevent their child from speaking. They fear that their child will so enjoy pressing those buttons that they will become lazy and not talk at all.

I totally get it!

Parents often feel overwhelmed by the task of getting their own heads round how to use AAC, either in paper form or a computerised system. This can be a great turn-off for lots of people who feel they are not very “techy” – like myself actually! Indeed, it is true to say that I resisted operating in this field for a long time as I didn’t feel able to navigate electronic devices. But fear not. Truly, most systems are very user-friendly. The support is great. And I have managed to become quite proficient in one or two of these systems, through using it daily. It really is as simple as that.

Alternative and Augmentative Communication (AAC)

There is plenty of research on the efficacy of Alternative and Augmentative Communication (AAC). It is now very well understood and proven that, once we introduce our child to a good, attractive way of communicating that they can actually do, in time children who can speak will speak. Speaking is more effective than any AAC system. It is more versatile, more fun, and when human beings have discovered how to speak, most will do so in favour of any other system.

Many children and adults, for many reasons, were never going to speak an awful lot, or with great difficulty. Or they were not going to like to speak. Or they were going to like to speak some times but not other times… And for all those people an AAC system is invaluable and a wonderful resource.

Neuro-diversity affirming means that we do not impose one system of communication on our children (speaking with our mouth) only because it is the one we are using and most people we know too.

Of course, we want the best for our children, and we want them to have the easiest and most straight forward existence on Earth. Of course we do. Speaking with our mouth does help with that. But we must come to understand that not all children and people feel like that and they struggle to use their mouth for talking.

Personal experience

I have difficulties understanding this myself, I will be very honest here. And I will say that – shoot me down in flames SLT fraternity – but I am learning to accept that using an AAC system proficiently is a very good alternative for when speech is not coming. I am learning to accept that some people are perfectly able to speak, and might do so but not always and only when conditions are right. I came into the profession as a speech therapist with the idea that I would help anybody that came to me to speak with their mouth. But I have changed my stance on that and now am happy to help anybody that comes to me to communicate most effectively with whatever works for them. I will always try for speech if I can … Just because it’s easiest!

Acceptance

Now I will equally celebrate a child pointing to a symbol or making a sign for something. It is a fantastic moment when it happens for the parents and me and the child! And we can always hope for more speech to come as we go. Nothing wrong with our aspirations, is there?

The basic premise is this: accept any mode of communication as valid, as long as your communication partner understands what it means. Don’t require individuals to repeat themselves in another modality. Do model the response in the modality you are trying to teach. So, a child can point to a symbol and I will respond with speaking (with my mouth) but I will also respond by pointing to a symbol because that way I am signalling that both are ok and that I have understood and am encouraging the person to say some more.

    From ‘Nailed it!’ in therapy to ‘Whoops!’ at home: Why generalising speech sounds is tricky

    ByLondon Speech and Feeding

    As a parent, you’ve likely experienced the triumphant feeling when your child, who’s been working so hard on his or her /S/ sound, produces it perfectly in a therapy session. He or she is rocking those ‘sun’ and ‘socks’ words, his or her lisp seemingly a distant memory. You leave feeling elated, confident that all that hard work is finally paying off.

    Then you get home. And within minutes, you hear it: ‘Thooper!’ instead of ‘Super!’ Or maybe the clear /R/ in ‘rabbit’ from therapy reverts to a ‘wabbit’ when his or she is playing with his or her toys. It’s frustrating, confusing, and can feel like you’re back to square one.

    So, what’s going on? Why is it so difficult for children to take those amazing skills learned in a focused therapy session and seamlessly apply them to their everyday conversations? You’re not alone in wondering this. It’s a common challenge in speech therapy and understanding the ‘why’ can help both parents and children navigate this crucial stage.

    The brain’s habits: Old pathways are strong pathways

    Think of your child’s brain as having established ‘pathways’ for how he or she produces certain sounds. If he or she has been lisping his or her /S/ sound for years, that neural pathway is deeply ingrained. It’s like a well-worn path through a field: easy to follow because it’s always been there.

    In therapy, we’re essentially trying to forge a new path. We’re teaching him or her a new, more accurate way to make the sound. This new path is initially faint, like a barely visible trail. It takes conscious effort and repeated practice to strengthen it. Outside of the structured therapy environment, his or her brain often defaults to the old, comfortable, and well-established pathway, even if it’s not the most accurate.

    The demands of daily conversation: A multitasking challenge

    Therapy sessions are designed to be focused and controlled. We isolate sounds, practice them in specific words, and provide immediate feedback. There are minimal distractions, and your child’s full attention is on his or her speech production.

    Now, consider daily conversation:

    • Speed: We speak much faster in natural conversation than we do during structured practice. There is less time to think about individual sounds.
    • Cognitive load: Children are simultaneously thinking about what they want to say, understanding what others are saying, processing social cues, and managing their emotions. Adding the conscious effort of producing a new speech sound correctly on top of all that is a huge cognitive demand.
    • Variety of contexts: In therapy, we might practise ‘sun’ and ‘socks’. In real life, the /S/ sound appears in countless words, in different positions within words, and alongside a vast array of other sounds. Each new word and phonetic context present a fresh challenge.
    • Lack of immediate feedback: In therapy, the speech therapist is right there to provide instant correction and reinforcement. In a playground, during a family dinner, or while playing with friends, that immediate, consistent feedback isn’t present.

    The role of automaticity: Making it second nature

    The ultimate goal of speech therapy isn’t just correct sound production; it’s automaticity. This means producing the sound correctly without having to consciously think about it. It’s like learning to ride a bike. Initially, every pedal stroke and steering adjustment is deliberate. Eventually, it becomes second nature.

    Generalisation is the process of moving from conscious, controlled production to unconscious, automatic production. This takes time, consistent practice, and exposure to a wide variety of real-life speaking situations.

    How can we help? Bridging the gap

    So, what can parents do to help their children bridge this gap between therapy success and everyday speech?

    1. Be patient and positive: This is a marathon, not a sprint. Celebrate the small victories and avoid getting discouraged by setbacks. Your positive reinforcement is crucial.
    2. Practise little and often: Instead of long, infrequent practice sessions, aim for short, consistent bursts throughout the day. ‘Sprinkle’ in opportunities to practise their target sounds in natural conversations.
    3. Create ‘sound awareness’ moments: Gently draw your child’s attention to his or her target sounds in everyday words. For example, if he or she is working on /R/, you might say, ‘Oh, you said ‘wabbit.’ Can you try to make your /RRR/ sound for ‘rabbit’?’
    4. Model correct production: Continue to model the correct production of their target sounds in your own speech.
    5. Collaborate with your speech therapist: Your therapist is your best resource! Ask them for specific strategies and activities you can do at home to support generalisation. They can also provide guidance on when and how to gently correct your child.

    Tips and tricks

    Below I have listed a few good tips and tricks that can help the transition from therapy room to daily life:

    Empowering your child as the ‘sound detective’:

    • ‘Secret sound listener’: Instead of you doing the correcting, make your child the detective. When you’re having a conversation, say ‘your /S/ sounds are sometimes a bit “slippery”’ (or whatever fun, non-judgmental term you like). Ask your child to quietly listen for your /S/ sounds. You can even purposely make a few ‘slippery’ ones (or correct yourself immediately after) and see if they notice. This shifts the focus from being corrected to actively listening and identifying the sound in a non-threatening way.
    • ‘Sound scorecard’: For a short period (maybe 10–15 minutes during a specific activity, like dinner or a game), provide a small notepad and pencil. Explain that your child is going to listen for his or her /S/ sounds and gently mark a tally every time he or she uses it correctly. The goal isn’t perfection, but awareness. This gives your child agency and a visual representation of progress. You can even make it a game: ‘Let’s see how many /S/ sounds we can catch in five minutes!’
    • /S/ sound song/rhyme creation: Work together to create silly songs or rhymes that are packed with /S/ sounds. The sillier, the better! You can sing them in the car, while doing chores, etc.
    • /S/ sound superpower: Frame the new sound skill as a ‘superpower’. ‘You’re getting so good at using your /S/ superpower! It’s going to help you speak so clearly and confidently.’
    • Highlighting successes: Always go out of your way to acknowledge and praise successful /S/ productions in natural conversation. ‘I really understood you clearly when you said ”s_top”.’ or ‘That /S/ sound was perfect when you told me about the “s_tory”!’

    Important considerations:

    • Keep it low-pressure: The goal is generalisation, not perfection. If your child is feeling pressured, he or she will likely revert to old patterns.
    • Focus on awareness, not just correction: Help your child become aware of his or her own speech rather than relying on you for corrections.
    • Short, frequent bursts: A few minutes of subtle focus multiple times a day is more effective than one long, forced session.
    • Acknowledge feelings: If your child expresses frustration about ‘being corrected’, validate these feelings. ‘I understand it can feel like a lot of listening, but we’re just trying to help you use that super /S/ sound all the time!’

    By incorporating these strategies, you can help your child naturally integrate the new /S/ sound into daily speech, fostering independence and confidence without it feeling like constant ‘testing’ or ‘correction’. Generalising new speech sounds is arguably the hardest part of speech therapy, but it’s also the most rewarding. With patience, consistent effort, and a collaborative approach between parents and therapists, children can successfully integrate their new, clearer speech sounds into every aspect of their daily lives.

    Chaining: A powerful tool for phonological development

    ByLondon Speech and Feeding

    Understanding chaining

    Chaining is a therapeutic technique I like to use in my speech therapy work with children who have Childhood Apraxia of Speech (CAS) or phonological speech sound difficulties. It helps to break down a complex target behaviour into smaller, more manageable steps. By systematically teaching and reinforcing each step, I can help my students achieve their communication goals.

    There are two types of chaining: Forward and backward chaining

    Today I am going to show and talk about backward chaining. This technique involves starting with the last step and working backward to the first. This approach can be particularly effective for children with persistent speech sound difficulties where combining consonants into clusters, such as /BL/ or /FR/ or /SHR/ is very difficult.

    Backward chaining allows my student to experience immediate success and build his confidence.

    In my video I show you how I applied backward chaining to the words ‘Shriek’, ‘Shrub’, ‘Shrimp’ etc

    My student struggles with both the /SH/ and the /R/ sounds and we have been working on both sounds for some weeks now. He has mild Childhood Apraxia of Speech and he has difficulties with coordinating his tongue movements, breathing and using his jaw effectively to make words. His sound repertoire has grown a lot since we started working together last year. Today in this session I show you how we pulled both the sound /SH/ together with /REEK/ to make ‘SHRIEK’. I love using the pictures and therapy materials from Adventures in Speech Pathology.

    This is also part of the Complexity approach which I will explain in a separate blog post.

    • Step 1 (not shown in the video): I explain what the word means; I find that when my student understands what a word means he is much better at saying it. It increases his confidence and motivation to say a word that he knows the meaning of. Often this student does not tell me that he does not know what a word means, so I always remind myself to check that out first.
    • Step 2 (not shown in the video): We do a little rhyming game and think about what any one word rhymes with: ‘Shriek’ – ‘meek’, ‘weak’, ‘seek’.
    • Step 3: I show my student that there are two parts to this word /reek/ and the sound /SH/.
    • Step 3: We practise the easier part: /reek/ /reek/ /reek/.
    • Step 4: We add the /SH/ sound and pull it together to make our target word ‘Shriek’.

    /REEK/ /REEK/ /REEK/ + /SH/ = ‘SHRIEK’
    /RUB/ /RUB/ /RUB/ + /SH/ = ‘SHRUB’
    /RUG/ /RUG/ /RUG/ + /SH/ = ‘SHRUG’

    By breaking down the word into smaller, manageable steps, my student can focus on each syllable individually, get that right and then gradually build up to the full word. This approach can help to reduce frustration and increase motivation.

    Forward chaining

    Forward chaining is the same process but in reverse: we start with the front sound or syllable and work forward towards the next/last part of the word:

    /SH/ + /REEK/ = ‘SHRIEK’
    /SH/ + /RUB/ = ‘SHRUB’
    /SH/ + /RUG/ = ‘SHRUG’

    Benefits of chaining

    • Increased motivation: By starting with the last step, my student experiences success, which boosts his motivation to continue trying to say the word and trying other words.
    • Reduced frustration: Breaking down the target behaviour into smaller steps can make the task less overwhelming, reducing frustration and anxiety.
    • Improved confidence: As the little learner masters each of the step, his confidence and self-esteem increases. Again, this leads to increased motivation.
    • Faster learning: By focusing on the final step first, and practising lots of chaining (forward and backward), a student can quickly learn to generalise to other words.

    Backward chaining (and forward chaining) is a really great tool for teaching complex speech sounds and words to children with phonological disorders.

    Watch out for my next blog which is all about the complexity approach in Phonology.

    Do get in touch if your child has a speech sound disorder, I would love to help.

  • A Day In The Life Of An Independent Speech And Language Therapist

    ByLondon Speech and Feeding
    A Day In The Life Of An Independent Speech And Language Therapist

    A Day In The Life Of An Independent Speech And Language Therapist

    I often get asked how many clients/children I see per working day or what my working day/life looks like. I always reply that every day is different, which is true, but there is a sort of average working day which looks a bit like this:

    I usually start preparing for my first client of the day at around 9.30 am: I clean the room, wipe down all the toys and materials (that’s if they are coming to my clinic room) and then it takes me about 30 minutes to select and sometimes make suitable materials, games and activities for the child’s therapy programme. Client arrives at 10.30 am and the fun begins. They leave around 11.30am, and the cleaning and wiping down starts again – yes it’s the pandemic but to be fair I would do this anyway. I quickly write up my notes and send home work to the client via email. Now it’s 12 noon and I start preparing for the next client at 12.30 pm. This might be online parent-child interaction coaching and so I need different materials and activities that are suitable for teletherapy. We finish around 1.30 pm and I will write up my notes before having some lunch.

    Lunch tends to not be around 30 minutes. Around 2.00 pm I start prepping again for the next client: selecting activities, going over their last session, making sure I have everything I need to start at 2.45pm – we finish at 3.45pm, I write up my notes and then have a cuppa. The next client might be more on-line coaching or a child coming to see me: room cleaned and tidy, materials and activities prepared: client arrives at 4.30 pm and we finish at 5.30 pm. I clean the toys again, write up my notes and it is 6.00 pm ready for dinner. So that was four clients between 9 am and 6pm allowing for preparation, aftercare, cleaning and coffee and lunch.

    Other days I might see three clients and do more admin like ordering toys or books or teletherapy activities, or making materials (we therapist make tons of materials, we’d put Blue Peter to shame!) Sometimes I do two home visits, one in the morning and one in the afternoon – the travelling/parking in London is so time consuming that it really reduces the number of clients I can see which is why I don’t do many of those.

    I hand pick my clients to make sure that we are a good fit, and my service is bespoke: no one client gets the same treatment as another; each client is unique, usually very well-known and always highly valued. That takes time and means that in reality each client gets about 2 hours of my time, that is the actual session plus all the preparation and aftercare.

    I love this way of working and would not ever want to return to seeing tons of clients each day, not knowing any of them really well, due to high caseload numbers, staff shortages and an overload of administration.

    My way of working affords all my lovely clients the help they need to be able to feel empowered and to then support their children to make progress; when working with children they make the best progress they can make, fulfilling their potential. My lovely reviews and testimonials tell me that my clients appreciate the extra attention.

    How parent coaching turns story time into a communication success

    ByLondon Speech and Feeding

    We often hear from parents who are trying their best to connect with their child, especially when reading books, but are met with frustration. They’ll say, ‘I read the book exactly as it’s written, but my child can’t focus for very long and just runs off!’ or ‘my child just flicks through the pages then turns it upside down and runs off with it’ or similar.

    It’s a common story. Traditional reading—going through the text from cover-to-cover—has its place of course, but for little ones with a language delay or autism it can move too quickly and place all the focus on the book’s words, not on the interaction.

    But what if I told you that story time could become one of the most fun and productive times for your child’s communication development?

    Watch the fantastic little video clip above! You can see the pure joy and connection between this dad and his son. This is the same family who, just a few weeks ago, felt defeated when trying to read a book, with their child quickly losing interest and leaving the reading/book corner.

    What changed?

    The power of parent coaching and Hanen principles

    The difference you see in the video is the direct result of parent interaction therapy, or parent coaching, based on the internationally recognised Hanen principles.

    I didn’t ‘fix’ the child. Instead, I coached the parents in a few simple, powerful strategies that completely changed the dynamic of their interaction. Instead of being a time for teaching and instruction, story time became a back-and-forth conversation.

    Here are the four major transformations that coaching helped this family achieve:

    1. From reader to play partner

    Before coaching, the parents felt their job was to read the text and to teach the words in it to their child. Now, their job is to follow their child’s lead. They learned to Observe, Wait, and Listen (OWL). If the child points to the tree or the badger on the page, the parent talks about the tree or the badger.

    The result

    The child is now initiating and leading the conversation! He is sharing what he finds interesting, which makes him feel powerful and keeps him deeply engaged.

    2. Building connection and attention

    When parents focus solely on reading, they often forget to make frequent eye contact and use animated facial expressions. The principles taught them to put the text aside and prioritise connection.

    The result

    Our little boy is looking at his dad more frequently, making great eye contact, and clearly having fun! When the interaction is fun, the child’s attention span naturally lengthens, allowing him to attend to the book and the interaction for a much longer time.

    3. Creating opportunities for communication

    The parents learned simple ways to prompt communication without pressure. They stopped asking knowledge-based questions (‘What colour is that? Or point to the pig!’), which can feel like a test.

    Instead, they learned to use techniques like ‘Saying less and pausing’ or ‘copying their little one’s echolalia ‘, signalling that they are very interested in what he is saying and that his communication matters!

    The result

    The child is now spontaneously using strings of sounds and gestures to communicate his needs and interests, knowing and enjoying his parents’ enthusiastic responses.

    This video is a testament to the fact that you are your child’s best therapist. With the right tools and coaching, you can transform everyday routines, like reading a book, into the most joyful and effective communication sessions.

    4. Acknowledging and interpreting echolalia

    In the video, you may hear the little boy repeat a phrase from the book or from what his dad just said. This is called echolalia, and for a long time, it was often dismissed or discouraged.

    However, a core principle of our parent coaching is that echolalia is communication. For children who are ‘Gestalt Language Processors,’ these memorised phrases (or ‘gestalts’) are their building blocks of language.

    The key is not to stop the repetition, but to become a ‘language detective’ and ‘interpreter’!

    By modelling the correct, first-person phrase right after the echo, parents/caregivers are teaching a child how to break down the ‘chunk’ and use the individual words functionally. They are showing their child: ‘I heard you. Your communication makes sense to me.’

    This strategy is a game-changer because it:

    1. Validates the child’s communication: It honours the child’s natural way of learning language, which boosts their confidence and willingness to communicate.
    2. Facilitates language development: It provides the child with the next step—a meaningful, functional phrase—to move them from repeating language to generating their own spontaneous sentences.

    Look at the child’s face again in the video. When his dad acknowledges and interprets his communication, you see that spark of joy and connection—that’s the moment when true, functional language learning happens!

    The hidden impact of mouth breathing and open mouth posture on speech and feeding

    ByLondon Speech and Feeding

    When most people think about speech or feeding difficulties, they picture the tongue, lips, or chewing skills, but how a child breathes at rest plays a surprisingly big role too.

    Mouth breathing and open mouth resting posture can quietly influence everything from how a child’s face grows to how clearly they speak, to how confidently they chew and swallow. It’s something many parents never think about, until they start noticing the subtle signs.

    Let’s explore why this happens, what to look for, and how to gently support better breathing and oral posture.

    Recent research supports this link between mouth breathing and speech difficulties. For example, a 2022 study by Alhazmi et al., published in the Journal of Pharmacy and Bioallied Sciences, found that 81.7% of children aged 9–17 who breathed primarily through their mouths presented with speech sound disorders. The study highlights how mouth breathing can significantly influence orofacial development and articulation patterns.

    💨 Why we’re designed to breathe through our nose

    Our bodies are made for nasal breathing. When we breathe through the nose, the air is filtered, warmed, and humidified before reaching the lungs. The tongue naturally rests against the roof of the mouth, the lips close gently, and the jaw stays relaxed, all of which encourage healthy oral development.

    In contrast, mouth breathing often means the tongue rests low in the mouth and the lips stay apart. Over time, this posture can subtly reshape how the muscles and bones of the face grow.

    Children who breathe through their mouths most of the time may develop:

    • A longer face and narrower palate
    • Forward head posture
    • Slightly open lips and low tongue position at rest
    • A tendency toward drooling or noisy breathing
    • A dry mouth and consequently bad breath
    • At times the tongue pushes constantly against the front teeth causing them to grow forward (buck teeth)

    These changes are not anyone’s fault, as they often start because of blocked noses, allergies, enlarged adenoids, low facial muscle tone or habits formed when a child was younger. But understanding the pattern helps us know how to support change.

    🗣 How mouth breathing affects speech

    Speech depends on precise coordination between the lips, tongue, and jaw. The resting position of these structures affects how ready they are to move.

    1. Reduced tongue strength and placement, i.e. the tongue rests low in the mouth (as it does in mouth breathing), it’s harder for children to lift it efficiently for sounds like /T/, /D/, /N/, /L/, and /S/. This can lead to speech that sounds slightly slushy or unclear, or a frontal lisp.
    2. Open mouth posture and resonance: An open mouth at rest may affect how air vibrates in the oral and nasal cavities. Children might have speech that sounds a bit ‘muffled’ or lacks crispness because the lips and jaw aren’t fully supporting articulation.
    3. Fatigue and breath control: Mouth breathing can lead to drier mouths and less efficient breath support. That can make longer sentences or conversations feel tiring, especially in noisy environments.

    🥄 How mouth breathing affects feeding and chewing

    Feeding involves the same structures that control speech, so posture and breathing patterns matter here, too.

    1. Chewing efficiency: Children who habitually keep their mouths open often have low tongue tone and reduced jaw stability. They may prefer softer foods, chew slowly, or struggle with mixed textures.
    2. Swallowing pattern: A tongue that rests low may push forward when swallowing. This ‘tongue-thrust swallow’ can interfere with efficient chewing and even affect dental alignment over time.
    3. Breathing while eating: Since it’s hard to chew, swallow, and breathe through the mouth simultaneously, children who can’t comfortably nasal breathe may rush bites or pause to catch their breath. This can contribute to coughing, choking, or food refusal.

    Common signs to watch for

    Parents often notice subtle clues before realising mouth breathing is a pattern. Some red flags include:

    • Lips habitually open at rest
    • Drooling after the toddler years
    • Snoring or noisy breathing during sleep
    • Preference for soft foods or grazing eating habits
    • Dark circles under the eyes due to allergies
    • Frequent colds, congestion, or mouth odour
    • Speech that sounds slushy or unclear despite good effort

    If several of these sound familiar, it’s worth mentioning them to your child’s GP, dentist, or speech and language therapist.

    👩‍⚕️ What can help

    1. Address the underlying cause: If nasal blockage, allergies, or enlarged adenoids are making nasal breathing difficult, a medical assessment is the first step. ENT specialists can rule out or treat physical causes.
    2. Encourage closed mouth rest: Gentle reminders like ‘Lips together, tongue up, breathe through your nose’ can help older children become aware of their resting posture. For younger ones, visual cues (stickers or mirrors) can make it a game.
    3. Build oral-motor strength and awareness: Speech therapists can design activities to strengthen the tongue and lips, improve jaw stability, and encourage balanced breathing. This might include blowing games, tongue-tip lifts, use of dental-palatal devices or oral-motor exercises disguised as play.
    4. Support good posture: Sometimes mouth breathing goes hand-in-hand with forward-head posture. Encouraging upright sitting during meals and screen time helps keep the airway open and supports better breathing habits.
    5. Make nasal breathing part of daily routines: Gentle nose-breathing practice during calm times (reading, bedtime, car rides) helps normalise it. Avoid making it a battle: calm, consistent reminders work best.

    🌱 A gentle note on change

    Patterns of mouth breathing develop over time, and change doesn’t happen overnight. It’s important to approach this with curiosity, not criticism. The aim isn’t ‘perfect breathing,’ but to give your child the tools and awareness to breathe comfortably and efficiently.

    Small improvements in nasal breathing and resting posture can lead to big gains in speech clarity, eating confidence, and even sleep quality.

    💡 The takeaway

    Breathing seems automatic, and it is! but how we breathe matters. Mouth breathing and open-mouth posture can quietly shape how a child speaks, eats, and grows.

    By noticing early signs, addressing underlying causes, and building supportive habits, you can help your child move toward stronger, clearer speech and more comfortable mealtimes.

    Just like every area of development, progress starts with connection, patience, and gentle consistency, one calm breath at a time.

    Milestones of autistic children: Crawling, walking, and talking

    For all children every milestone achieved is a testament to the unique and intricate process unfolding within each young mind. For autistic children, this journey may present a distinct pattern, with some reaching developmental milestones like crawling, walking, and talking later than their neurotypical peers. Let’s have a look into the fascinating realm of Autism and explore why some autistic children might crawl, walk, and talk later, shedding light on the underlying factors contributing to this unique way of developing.

    1. Individual Pacing:

    Child development is not a one-size-fits-all journey. Each child, whether neurotypical or autistic, has a unique timeline for achieving milestones. Autistic children, like any other children, follow their own pacing. This individual rhythm might lead them to focus on one set of skills before they progress to others. Like some neurotypical children might focus on talking earlier than walking, autistic children might prioritise other areas before crawling or talking.

    2. Neurodevelopmental Complexity:

    The human brain is a remarkable entity, with a bewildering array of interconnected processes that lead to us achieving our developmental milestones. Autistic children often have variations in “neural wiring”, which can impact the balance between gross motor skills (crawling, walking) and fine motor skills. Speech and language acquisition falls under fine motor skills and may be momentarily disrupted due to the divergent neurological pathways at play in autism.

    2. Sensory Processing Differences:

    One of the hallmarks of autism is altered sensory processing. Autistic children often experience sensory stimuli differently than their neurotypical peers. This heightened or diminished sensitivity can influence a child’s desire or ability to engage in activities like crawling and walking. The sensation of movement while crawling or walking, for instance, might be overwhelming for some autistic children, causing them to either avoid or delay these activities.

    3. Visual-Spatial Abilities:

    Autistic children and adults frequently display excellent visual-spatial abilities. This strength might lead some children to focus more on activities that engage these skills, potentially delaying their engagement with activities like walking or talking. As they navigate their environment and process information visually, they might naturally invest more time in activities that stimulate this particular cognitive ability and strength.

    4. Communication Challenges:

    For many autistic children, speaking can be a really complex and difficult endeavour. Communication delays are a common feature of autism. This can affect both receptive and expressive language development. While some children might be physically capable of crawling or walking, they may not yet have the tools to communicate their desires and intentions. This leads to a temporary focus on non-speaking forms of expression. This does not mean that they do not communicate at all. But autistic individuals often start out using jargoning or echolalia as a form of communication as well as behaviours and physical forms of communication.

    5. Executive Functioning and Motor Skills:

    Executive functioning, or abilities for planning, organising, and carrying out tasks, can vary in autistic children. These skills are crucial for activities like crawling, walking, and talking, which need coordination and planning. About 40% of autistic persons have a motor planning difficulty.

    6. Intense Interests and Routines:

    Autistic children often develop intense interests in specific subjects, sometimes to the exclusion of other activities. These interests might become their primary mode of engagement. They might side-line milestones like crawling, walking, or talking. The mostly rigid adherence to routines and preferences might cause them to allocate more time to their preferred activities. This delays their engagement with other developmental tasks.

    How can Speech and Language Therapy help:

    Support and Intervention:

    Early intervention and regular Speech and Language Therapy play a pivotal role in the developmental journey of autistic children. Therapies tailored to individual needs can aid in bridging the gaps between milestones. Occupational therapy, for example, can help address sensory sensitivities and motor skill challenges that might impact crawling and walking. Speech therapy can help communication development, gradually bridging the gap between non-verbal expressions and spoken language.

    For example, we now know that echolalia or jargoning of longer phrases with intonation, repeating scripts from favourite tv shows or songs have many meanings and communicative functions. For example, a child who utters long strings of echolalic utterances, often difficult to understand, might want to do any one of the following:

    • Comment
    • greet
    • ask a question
    • make a request
    • express surprise
    • negate something.

    We now understand that the way to support a child with echolalia is to acknowledge all utterances and try and find out what the meaning is behind these scripts. This is very supportive. Over time it will lead a child to move on to understanding and saying more clear and self-generated language.

    Conclusion

    In conclusion, the journey of an autistic child’s development is a testament to the uniqueness and complexity of the human mind. The delays or differences in achieving milestones like crawling, walking, and talking can be attributed to a range of factors, including

    • neurodevelopmental intricacies,
    • sensory processing variations,
    • and communication challenges.

    It’s crucial to recognise that these delays are not indicative of a lack of potential, but rather a manifestation of the intricate interplay between an autistic child’s strengths and challenges. By embracing these differences and providing tailored support, we can help each autistic child unfold their potential at their own pace.
