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.

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.
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.
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.

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.
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.
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

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.
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.
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.
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.
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.

How can I incorporate AAC into my speech therapy sessions?
ByLondon Speech and Feeding March 2, 2026February 26, 2026
Many parents are surprised when I bring AAC into a session, especially if they’ve come to see me primarily for speech sound work.

They might wonder: ‘If we’re working on pronunciation, why are we using a communication device?’

The simple answer is this: speech therapy is about communication first, and speech sounds second. Supporting a child’s ability to express themselves clearly and confidently is always the priority, and AAC can be a powerful tool alongside spoken speech.

What do we mean by AAC?

AAC stands for Augmentative and Alternative Communication.

This can include:
- A speech-generating device (such as LAMP Words for Life or GRID as I used in the photo below)
- A communication app on a tablet
- A symbol board or communication book
- Gestures, signs, or visual supports
AAC does not replace speech. Instead, it supports language development, reduces frustration, and builds communication success while speech skills are developing.

Pretend Play using Speech and AAC in my clinic room

But I mainly work on speech sounds… So how does AAC fit?

Most of the children I see are working on:
- Articulation difficulties
- Phonological delay
- Motor planning challenges (including apraxia/dyspraxia)
- Unclear speech affecting confidence
For these children, AAC isn’t a separate therapy. It’s simply woven naturally into what we are already doing.

If a child brings their device to sessions, I actively include it. If they don’t yet use AAC but could benefit from visual or symbolic support, I may introduce simple options within activities.

Using AAC to support speech practice

Let’s say we are working on early speech targets like: ‘GO’.

We might practise:
- Saying the word verbally
- Listening for the target sound
- Using play (TOY TRAIN GOING ROUND A TRACK)
Now we can extend this using AAC.

On the device or communication board, we might model: ‘LET’S GO’ or ‘IT’s GOING up the hill’.

This allows the child to:
- Practise their speech sound target
- Build a simple sentence
- Experience successful communication even if speech is not fully clear yet
All responses are valid and supported.

AAC helps children communicate more than they can say

Many children can understand and think in longer phrases than they can physically say.

For example:
- A child who verbally says single words may build longer phrases on AAC.
- A child who struggles to plan speech movements may use AAC to communicate smoothly while still practising verbal attempts.
- A child who becomes frustrated when misunderstood gains a reliable backup system.
Rather than slowing speech progress, AAC often:
- Reduces communication pressure
- Increases participation in therapy
- Encourages more attempts at speech
- Supports language growth
When children feel understood, they usually become more motivated to try speaking.

There are no ‘prerequisites’ for AAC

One of the biggest myths I hear is: ‘My child isn’t ready for AAC yet.’

In reality, children do not need to:
- Reach a certain speech level
- Use pictures first
- Prove they understand everything
- Show immediate interest
Instead, we presume competence and introduce AAC in meaningful, playful ways.

That means:
- Modelling words while blowing bubbles
- Commenting during playdough activities
- Choosing words during games
- Building simple phrases in shared reading
AAC should never feel like extra ‘work’. It’s simply another way to join in communication.

My goal is always the same: to help each child communicate as clearly, confidently, and successfully as possible, using every helpful tool available.

If your child uses AAC (or might benefit from it)

Please feel free to:
- Bring the device to sessions
- Show me how your child currently uses it
- Share advice from school or other therapists
I am very happy to incorporate AAC into our work together so that speech practice, language development, and real communication all move forward hand-in-hand. Because ultimately, therapy isn’t just about producing perfect sounds. It’s about helping your child be heard and understood.

If you’d like support or advice, please contact me and I can help guide the next steps.

Lisp · Speech and Language Therapy · Top tips

Living life with a lisp
ByLondon Speech and Feeding June 9, 2023June 27, 2025
You may be questioning ‘will my child grow out of having a lisp?’ There are so many myths out there that it’s sometimes difficult to find your way out of a complex maze of information.

The good news: lisps can be successfully treated by a Speech and Language Therapist and the earlier it’s resolved, the better. We know from the evidence base that some children’s lisps will resolve and, as always, it is completely age appropriate to have this speech pattern up until aged 4 ½.

As with any speech and language targets your child will need to be motivated to practise their newly acquired techniques, at home and in other settings. They will eventually be able to generalise this skill, but it takes lots of practice. So, think carefully about if your child is ready and motivated before commencing Speech and Language Therapy.

There are essentially two ways in which your child has acquired a lisp. It’s key here to mention that parents have no blame in this.
1. They’ve mis-learned it and now incorrect production has become a habit
2. Children have difficulties organising the sounds to make a clear production
You may be surprised to realise that there are different types of lisps. But all the techniques will be the same.
1. Interdental lisp
When your child pushes their tongue too far forward, they will make a /th/ sound instead of /s/ and /z/
1. Dental lisp
This is where your child’s tongue pushes against their teeth
1. Lateral lisp
Air comes over the top of the tongue and down the sides
1. Palatal lisp
Your palate is the roof of your child’s mouth. Sometimes they will touch their palate when making certain sounds (e.g., /s/ and /z/)

It’s useful for you to know what type of lisp your child has because you can then support them to make the correct production. You’ll be able to talk about where in the mouth their tongue is and where it needs to be to produce a clear sound. Your Speech and Language Therapist will be able to help you with this.

Top therapy tips for lisps
1. Awareness is key. Does your child know where their tongue and teeth are (i.e., are they behind their teeth)? Do they notice the air escaping? Use a mirror so that your child can see not only themselves but also you in the mirror.
2. Repetition! As with most therapeutic intervention, practice makes perfect. So little and often is key!
3. Make sessions fun, perhaps around your child’s interests or allow them to drink from a straw
4. Comment on how the sound is produced (e.g., /z/ is like a bee, /s/ is like a snake)
5. Use tactile cues. Your child’s vocal folds vibrate when they produce a sound like /z/ but not with /s/. You could use the words ‘loud’ and ‘quiet’ to describe this.
6. Start with a /t/ sound and gradually elongate the sound to an /s/
Having a lisp may not be problematic for some, but for other children, it can have a significant impact on their emotional wellbeing. Intervening at an early age can prevent this from happening. We always advocate for early intervention!

Support your child’s communication using books: OI FROG
ByLondon Speech and Feeding March 17, 2023February 10, 2023

Oi Frog by Kes Gray and Jim Field

Book corner with Oi Frog! by Kes Gray and Jim Field.

Books are an engaging way to support your child’s communication development. Even if your little one dislikes reading in the traditional sense. They will become immersed in this adventure, without realising they are taking in language and developing vital communication skills. This is one of my favourite series for children.

Increase fun and interaction

These books are made for fun and excitement! It may seem silly putting on different voices for different characters, but this is one way in which you can engage your child. Why not try to use different intonation patterns (e.g., you may use a deep voice for the dog, and a higher pitch for the cat)? Make your story interactive: you could ‘rawww’ like a lion and see who can make the loudest noise. Make noises to encourage interaction (e.g., when scratching his chin, make a squeaky sound!). You could also relate the experience back to your child (e.g., ‘can you scratch your chin?’).

Time to talk

Talk about what you can see on the front cover (e.g., There’s a frog on a log, how funny!) You could also ask your child to choose the rhyming words on a page in the book. Can your child tell you what rhymes with certain words (e.g., can you guess what a parrot sits on?)? Make use of every page. You could comment on your favourite frog and see if your child can talk about their favourite. You can support them by giving them an example (“my favourite frog is the one swimming backwards because he looks funny”). Then you could use this scaffold to support their answer. Your favourite is [________________] because [_________________]

If your child is reluctant to use language, the use of commenting can take the pressure of them (“look at all those frogs” or “he’s climbing up the stool”) is a powerful way in which you (as parents) can take the pressure off your child. A top tip I like to give is to make sure you pause regularly, which creates opportunities for your child to use language.

This book uses a subject-verb-object sentence structure (e.g., ‘hares sit on chairs’) which allows your child to hear a good model of a sentence. You could also talk about things in the book that belong in a certain category (e.g., animals, food) or begin with a specific sound. See if your child will name any more.

Reap the reward of repetitive language

Oi Frog uses repetitive rhyming language and puts emphasis on these words. This is important because the more your child hears a word, the more likely they are to remember, understand and use it in the correct context.

Emotions matter

Talk about how the animals feel and why they may feel this emotion (e.g., the cat’s feeling annoyed because…, Lions sit on irons, how does the lion feel?). Reasons can be difficult for children with communication difficulties. Support them by giving an example or by giving them an option (e.g., “does the lion feel happy or sad? I think the lion feels sad because he’s burnt his bottom on the iron! It’s too hot!”)

OI Books

Why not read similar stories? I highly recommend OI CAT, OI DOG and OI DUCK-BILLED PLATYPUS.

Using AAC – Augmentative and Alternative Communication for non-verbal and early verbal children
ByLondon Speech and Feeding July 27, 2021March 28, 2025
Your Speech Therapist might have been advising you to introduce words to your child with the help of a CORE BOARD. What on earth is she talking about and why would we want to do this, I hear you think – and in fact this is what I get asked a lot, as I often do recommend using Core Boards.

Core boards belong to the category of Augmentative and Alternative Communication (AAC ) and they can be really useful for:
- Children or adults who cannot speak at all or who are very hard to understand.
- Children who are slow to speak and have difficulty expressing themselves verbally, due to genetic conditions as Down Syndrome, Verbal dyspraxia, Autism or any other learning difficulty that means a child is slow to develop speech.
Here is what a Core board might look like, in fact this is one that I love to use. It is made by Beautiful Speech Life, there are a ton of similar boards out there for free. I have also made my own, you can check it out on my Instagram feed.

What is Core Vocabulary/ Core words?

Core vocabulary consists of the most common words used by children throughout a day. In 2003 Banajee and Dicarlo et al found that 50 % of pre-schoolers in their project used nine words consistently across their daily play and meal routines. These words are Core words and are typically the ones you can see on a board, like the one above.

How To Use It

Adults always first need to consistently model and show their child how to use a board. This is key! For example: Adult can point to “YOU” “WANT” ‘MORE” and then point to the cup of Water on the counter. Child could then reply either by shaking his/her head and/or pointing to “NOT” which also stands for “NO”. Then adult can point to “NOT” “MORE” and do an OK sign as well. Eventually Child can initiate a request and point to “I” “ WANT” “MORE” and then point to the cup on the counter.

This is not as cumbersome or limited as it first sounds or appears. Here’s why: As adult you can talk normally and, of course, many words you are using will not be on this board. But some will be, and you will be surprised how many you can find when you start using it. So you could say quite normally: Hey lovely (name of your child) would YOU LIKE some MORE water? The words in capital are on the board which you can point to as you speak normally. Basically, you are showing/saying to your child: “We can speak and these are the pictures we can use to help us; We call this TOTAL COMMUNICATION, as communication is so much more than just words! Great communication can be silent, where we use our facial expression, our smile, our eyes, our hand gestures, body movements and yes, of course, words. But when words fail us, these boards are so helpful.

This still does not answer your original question of: why would I want to do this, I want my child to talk!? You are a SPEECH Therapist, please help my child TALK, not point to pictures, that is not what I had in mind.

Let Me Explain

When speech is difficult for a child it doesn’t mean that there is nothing to talk about! Of course, we want all our children and all people to speak because it is the easiest and most effective way of communicating, no doubt! However, sometimes this is very hard for some children and whilst we are always working towards speech where possible, we also want to make sure that whilst figuring out how to speak, your child has a MEANS TO COMMUNICATE. Using a board like this might well be a temporary strategy but whilst you are using it and working on their speech you will find a reduction in tantrums and frustration as you child is able to express themselves more effectively.

Often we find that as soon as we offer a CORE VOCABULARY like the above sample a child who has had no or very few words suddenly blossoms and starts to point to new words on the board and starts to PRACTICE USING THESE WORDS!! Practice makes perfect, right? Yes it totally does! There is lots of evidence that tells us that using Core Vocabulary Boards ENHANCE AND SUPPORT SPEECH PRODUCTION AND NOT HINDER IT. Using a board like this will only ever be helpful to your child and will never make your child “lazy” – too lazy to speak? NO SUCH THING!

Here is what one of my parents says about the core board we use with her little boy:

“the board has been a game changer, my son is a visual learner so it really helps to have the board as he associates communication so much easier this way. We have incorporated his twin sister who models it’s use and have definitely seen improvement in speech through its support and his frustration around being unable to verbally communicate at times has definitely lessened”
K Connolly, Mother of Tom (aged 3.5 years).

Reading and hearing this makes me so happy!

In addition to general core board above I also sometimes use a Core Board that is specific to an activity, such as for example BLOWING BUBBLES. Below is an example of such a board, which you can use very nicely during a bubble blowing activity and sometimes it is a nice place to start for newcomers, this can be an easy introduction. You can download this and many similar boards on www.widgit.com for free!

There is so much more to say about AAC and using Coreboards, visit my Instagram you can find a bit more information on how I use them.

Echolalia · Speech and Language Therapy

What Is Echolalia And Does It Have A Function? How Can Speech Therapy Help With Echolalia?
ByLondon Speech and Feeding January 11, 2022January 31, 2023
Echolalia is a term used when assessing or treating children with Autism. The term refers to the repetition or echoing of utterances, either our own or others’. It can also be echoing phrases heard on television, advertising jingles or catchy repeat phrases used in tv programmes or nursery rhymes and songs. Whilst we all use echolalia occasionally and it can be observed in typically developing children, we tend not to see/hear it beyond the age of 2.5 years old. Children with ASD, however, do use echolalia often into late childhood.

There are generally two types of Echolalia:

Immediate echolalia

Here the repeated phrases or words are produced immediately after someone has spoken the original words or within two conversational turns of the original utterance.

Delayed echolalia

The repeat echoing of the original utterance occurs sometime later, more than two conversational turns or with a much longer time delay. Due to the delay it can be hard to interpret the meaning of the echolalic utterance as it may refer to something that happened long ago and in a different context to the originally utterance.

(Stiegler, 2015, Fay 1967, Blanc 2014)

There are other unconventional speech behaviours which include:
- Perseveration of Speech – persistent repetition of speech
- Repetitive questioning – persisting even though answers were given
- Vocalisations such as: humming, whistling, clicking, squealing etc.
Much research has gone into the meaning and treatment of Echolalia and the following list consists of possible functions that have been identified:
- Information sharing
- Responding to answers
- Labelling
- Drawing attention to self
- Protesting
- Requesting
- Giving instructions
- Self-regulation, calming
(Stiegler 2015, Prizant 1983)

Echolalia does have a function and is part of the Gestalt Learning Process (where longer units of speech are memorised and then used as a whole without the individual words being meaningful).

As a Speech and Language Therapist I promote sound and proven Intervention based on the Hanen Programme which helps provide a highly facilitative Interaction Style and I will tell you a bit more in my next blog how the “More Than Words” approach can help children with echolalia move through their Gestalt Learning into more analytic processing of language, grammar and meaning.

The great air debate: How different swallowing patterns impact breastfeeding and reflux
ByLondon Speech and Feeding November 5, 2025November 6, 2025
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.
