Tongue training: Why tongue placement matters for clear speech

ByLondon Speech and Feeding February 12, 2025February 3, 2025

As speech and Language therapists (SLTs), we know that where your tongue goes, so goes your sound. This blog post will explore why tongue placement is so vital for speech correction and how we use tools and techniques to help our clients find their ‘sweet spot’ for sound production.

Let me show you here a little video clip where I am using my dentist’s mouth/teeth model to help my clients navigate their tongue movements.

The tongue: A tiny muscle with a big job

The tongue is a small but mighty muscle. It’s incredibly versatile, playing a key role in eating, swallowing, and, of course, speaking. For each speech sound, the tongue, along with the lips and jaw, needs to move to a very specific spot. Think of it like a dance: every part of your mouth has a choreographed movement to produce the correct sound. If the tongue is out of sync, the sound comes out muffled, distorted, or just plain wrong.

The trouble with our tongue movements is that most of us never think about how the tongue has to move and what it does to: swallow, chew, drink, suck and speak. Most parents when asked to think about their own tongue placement for say the /S/ sound are completely lost as to what their tongue is doing. Yet, of course, they produce a perfect /S/ and perfect speech in general. The same goes for swallowing. When did you last think about what happens in your mouth when you swallow? I bet you have not thought about it. We ‘just do it’, right?

Why is tongue placement so important?

Accurate tongue placement is the foundation of clear articulation. When a child struggles with a particular sound, it’s often because his or her tongue isn’t quite reaching the right spot or moving in the correct way. For example, the /S/ sound requires the tongue to be slightly raised and positioned behind the top teeth, creating a narrow channel for air to flow through. If the tongue is too far forward, you might get a /TH/ sound instead. If it’s too far back, the /S/ can sound muffled.

Visual aids: Our secret weapon

We SLTs love our visual aids! They’re incredibly helpful for showing clients exactly where their tongue needs to be. Here are some of our favourite tools:

Mirrors: Mirrors provide instant feedback. Clients can see their tongue’s position and make adjustments in real-time. We often use hand mirrors or even the mirror on a compact for quick checks.
Tongue depressors: These simple tools can gently guide the tongue to the correct position. We might use them to show where the tongue tip should rest for the /L/ sound or how the sides of the tongue should touch the molars for the /K/ and /G/ sounds.
Diagrams and models: Pictures and models of the mouth can help clients visualise the tongue’s movements. We might use a cross-section diagram of the mouth to show how the tongue forms different sounds.

Beyond the tongue: The jaw’s role

While the tongue takes centre stage, the jaw plays a supporting role. It provides a stable base for the tongue and helps control the opening and closing of the mouth. Sometimes, jaw stability is an issue, and we might use techniques to help clients find a comfortable and stable jaw position.

Making it fun and engaging

Learning correct tongue placement can be challenging, but we make it fun! We use games, stories, and playful activities to keep clients motivated. For younger children, we might use silly voices or pretend to be animals. For older children, we might incorporate their interests, like using a car analogy for tongue movements.

The takeaway

Correct tongue placement is essential for clear speech. By using visual aids, interactive techniques, and a bit of creativity, we can help our clients master their speech sounds and communicate with confidence.

How can we support babbling and early speech development? SLT tricks and tips
ByLondon Speech and Feeding May 3, 2024May 3, 2024
My baby isn’t babbling and developing speech – what can I do to support?

While every baby develops at their own pace, if your child isn’t babbling by nine months, it’s worth seeking help from an Early Intervention Health Professional, such as a doctor and a speech therapist. Don’t panic! There are many reasons for delayed babbling, and early intervention is key.

In the meantime, it is highly recommended that we talk, sing, and read to our baby often. Exaggerate sounds and expressions, and respond to their coos and smiles. This playful interaction helps stimulate their communication skills.

Below are some tips and tricks from my experience of working with babies and toddlers who need a little bit of help and support to develop.

The benefits of imitating your baby

Copying your baby’s sounds and gestures isn’t just silly fun, it’s a powerful learning tool! By mimicking their babbles and actions, you activate “mirror neurons” in their brain that help them connect sounds with meaning. This playful back-and-forth teaches turn-taking, a foundation for conversation. Plus, it encourages them to copy you, building their own language skills and social interaction abilities.

This is a nice clip on youtube showing how copying/imitating your baby looks like:

Here are some fun ways to imitate your baby:
- Matchmaker: Grab two of the same, or two similar toys your child loves, like rainmakers or shakers. Give one to your baby and keep the other for yourself. When your child plays with his/her toy, mirror his/her actions with yours! This creates a fun, interactive game.
- Face Time: Get down to your baby’s level, sitting opposite him/her on the floor or kneeling. This makes eye contact easy and encourages him/her to look at you during your playful imitation.
- Be the Funniest You: Go all out with silly faces, exaggerated sounds, and big gestures. The goal is to capture your baby’s attention and make you irresistible to watch. This playful energy encourages him/her to interact and potentially imitate you back!
By incorporating these tips, you can turn imitation into a fun and engaging way to boost your baby’s communication skills. I have seen this happen numerous times over the past decades. It is very powerful, go ahead and try it! You cannot be silly and goofy enough!

Great toy ideas:

Steel Tongue Drum

Baby Rainbow Rattle toys

Organza Veil Fabric good for hide and seek

Light up magic ball toy wand

The Glowhouse flashing swivel fan

Mini portable hand held body massager

Hape Beaded Raindrops

Bubbles – always handy keep in every room

Montessori Mirror

Antic Duck Peekaboo Knob Puzzle Suction Cup Spinner toys

Did you know that speech and language development starts with how we talk to our babies?

Adults naturally use a special way of speaking called motherese. It involves a higher pitch, slower pace, and exaggerated sounds compared to regular conversation. Sentences are simpler, with shorter words and repetition. This grabs babies’ attention, helps them distinguish sounds, and reinforces word meaning.

Imitation is a key part of motherese. We wait for our baby to make a sound or gesture, then playfully imitate it with exaggeration. Babies notice this right away and often respond with more vocalisations, creating a mini conversation. This back-and-forth teaches turn-taking, a foundation for future conversations.

By responding warmly and engaging in these playful interactions, we encourage our babies to keep exploring the world of communication. Talking, singing, reading and, of course, imitating, these simple actions can have a big impact on a baby’s language development.

Once your conversation is underway then try and keep it going for as long as possible. It’s a beautiful dance of turn-taking, even without words!

A last word on oxytocin

There’s evidence suggesting early non-verbal communication with your baby can increase a mother’s oxytocin levels, often called the ‘love hormone’. This hormone plays a key role in bonding and social connection. Positive interactions, touch, and stress reduction all contribute to oxytocin release, strengthening the mother–baby bond.

For parents of babies with extra needs

The stress of caring for a child with medical needs or developmental delays can be difficult. Stress can lower oxytocin levels, creating a cycle of sadness for both parent and child.

Breaking the cycle:
1. Knowledge is Power: Understanding the importance of communication can empower parents.
2. Seek Support: Speech therapists and other healthcare professionals can provide valuable guidance on communication strategies.
3. Start Small, Celebrate Big: Even small interactions can boost oxytocin. Focus on playful imitation and positive reinforcement. Remember, friends, family and healthcare professionals are there to encourage you.
This approach can help reverse the negative cycle and create a more positive and connected relationship between parent and child.

I hope this is helpful! Don’t hesitate to reach out with any questions.

Kind regards

Milestones of autistic children: Crawling, walking, and talking
ByLondon Speech and Feeding October 25, 2023March 25, 2026
Image by wayhomestudio on Freepik

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. For more information about this Natural Language Acquisition here are some other great websites for you to look at:
- https://www.meaningfulspeech.com/
- https://communicationdevelopmentcenter.com/the-natural-language-acquisition-guide-echolalia-is-all-about-gestalt-language-development/
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.

When ‘star’ sounds like ‘dar’: Understanding speech sound disorders and the path to clearer speech
ByLondon Speech and Feeding January 26, 2026January 21, 2026
If your child says ‘dar’ instead of ‘star’, you might be wondering if they will simply outgrow it or if they require specialised support. While ‘cluster reduction’—dropping one of the sounds in a blend—is a normal part of learning to talk, we typically expect these sounds to lock into place by age four years. If these errors persist as a child approaches school age, it often signals a speech sound delay that may now no longer pass without help. As a Speech and Language Therapist, I specialise in helping children bridge this gap using evidence-based techniques like backward chaining.

This isn’t about constant correction; it’s about providing the right clinical scaffolding to move a child from ‘frustrated’ to ‘fluent’ before they hit those critical early school years.

Dropping sounds from words is a common feature of speech sound difficulties, and while it can look small on the surface, it can have a big impact on how clearly a child is understood. In this short video clip, I’m working with a child on an /ST/ sound cluster, demonstrating how I use an evidence-based speech therapy technique called backward chaining to help children build clearer speech with confidence.

What’s actually happening when a child drops the ‘S’?

Clusters like /ST/, /SP/, and /SK/ are tricky. They require:
- precise timing
- careful airflow
- and the ability to blend sounds smoothly
For many children, especially those with speech sound difficulties, this is a big ask.

So instead of hearing:

‘star’

we might hear:

‘tar’ or ‘dar’

This isn’t laziness or refusal. It’s the child simplifying the word to make it manageable.

Why I don’t start by saying ‘say star’

Telling a child to ‘just add the S’ rarely works.

Instead, I meet them where they are already successful.

In this clip, the child can already say ‘dar’ clearly. That’s our starting point.

Backward chaining: building speech from success

Backward chaining means we:
1. Start with the part of the word the child can already say
2. Gradually add the missing sound
3. Keep the child feeling successful at every step
So rather than jumping straight to ‘star’, we:
- secure the ending
- gently introduce the /S/
- and blend it in a way that feels achievable
This approach reduces frustration, builds confidence, and helps the sound stick not just in the therapy room, but out in the real world.

Why this matters beyond one word

This isn’t just about saying ‘star’.

It’s about:
- teaching the mouth a new movement pattern
- giving the brain time to organise the sound sequence
- and helping the child feel capable, not corrected
When therapy feels safe and successful, children are far more likely to generalise their new sounds into everyday speech.

Speech therapy works best when children feel supported not tested.

If your child struggles with speech clarity

If your child:
- drops sounds from words
- avoids longer or trickier words
- or becomes frustrated when they’re not understood
This is the kind of work I do every day building speech step by step, in a way that respects each child’s pace and strengths.

Support can be gentle, effective, and empowering.

If you’d like to learn more about how speech therapy can support your child, you’re always welcome to get in touch.

Could mouth breathing be affecting your child’s speech, sleep and development?
ByLondon Speech and Feeding June 15, 2026June 11, 2026
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.

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.

The joyful language toolkit: Strategies for connecting with your child through play
ByLondon Speech and Feeding October 15, 2025October 9, 2025
As parents and therapists, we all want to help our children communicate. But sometimes, the process can feel like ‘work’. If I had a penny for every parent saying ‘I find it so boring!’… Ok hang in… what if I told you the most effective therapy happens when it doesn’t look like therapy at all?

My approach centres on connection, enthusiasm, and multi-sensory engagement. We don’t just teach words; we teach the joy of using them. These strategies can be used whether your child is speaking, using a core board, or communicating in his or her own unique way.

Some of my favourite strategies

Today I want to share a few of my favourite strategies to turn everyday interactions into powerful communication opportunities regardless of why or how big a delay your child is having.
1. Facial expressions & exaggeration: Use an exaggerated facial expression to show surprise (wide eyes!), excitement (big smile!), or confusion (a crinkled brow!). Your face is a powerful teaching tool. I am always talking like a clown in my sessions. I can announce that I have also a normal speaking voice outside my clinic room! 😊
2. Using your voice with intonation: Your voice is music! Use a singsong or ‘tuneful’ repeat to make words stand out. For example, ‘It’s a BIIIG ball!’ or ‘Let’s GO-O-O!’. Again think: clown!!
3. Hands and body to show: Use gestures, hands, and body movements to demonstrate. Say ‘OPEN’ while pulling your hands apart, or ‘UP’ while raising the toy high above your head.
4. Elongating our words: Stretching out key sounds or words gives them emphasis and more time for your child to process. ‘Criiiinkley’ ‘tiiickleyyyy’
5. Core board & language modelling:
  
  Model the core board with joy: Don’t just point: point with energy!
  
  Model the core board repeatedly throughout the activity, showing genuine excitement. This demonstrates the board is a joyful tool, not homework.
  
  Pointing to the core board: When you say a core word, point to the corresponding symbol. You are showing your child, ‘My words live here, and your words can too’.
6. Describing it for your child: Help your child build his or her vocabulary by providing rich sensory language. ‘It’s squishy’, ‘It’s very noisy’, or ‘It’s so smooth’.
7. Catchy phrases: Repetitive, positive phrases create a sense of shared fun. Use them consistently: ‘Oh, that’s a nice one!’ or ‘We like that!’
8. Following your child’s Interest: Put down your agenda and follow your child’s lead. If they pick up a block, talk about the block. This ensures they are engaged and ready to learn.
9. Allowing for pauses: This is critical! After you made a comment, allow for a significant pause (count to five in your head) for your child to fill. The silence creates a powerful opportunity for them to initiate communication.
10. Copying your child’s sounds: If he or she makes a sound (‘buh!’), you make the sound back! Copying your child’s sounds shows him or her ‘I hear you, and your communication is important’.
11. Lots of repetition: Hearing a word many times in meaningful contexts is how we learn! Repeat key phrases and core words throughout the activity. Repetition is the key to retention.
12. Getting turns: Explicitly teach and celebrate getting turns in a game. ‘My turn! Your turn!’ This is a foundational social and communication skill.
13. Using tidy up as a teaching activity: Turn cleanup into a fun game! It’s a goldmine for core words like PUT IN, ALL DONE, HELP, and MORE. For example, ‘Let’s PUT IN the red block! Yay!’
14. Using exaggerated repeats: When your child tries a sound or word, give it back with exaggerated, tuneful repeats.
Try out all or even just a few of these strategies, and I can promise you, you’re not just encouraging language; you’re building a joyful, reciprocal relationship based on genuine communication!

Which strategy are you excited to try first? Let me know in the comments!

If I can help you with any of the above, if you want to practise these a bit more, I would love to help you!

The hidden impact of mouth breathing and open mouth posture on speech and feeding
ByLondon Speech and Feeding November 17, 2025November 17, 2025
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.
