Parent Tips – The London Speech and Feeding Practice

What to do when words don’t come fast enough

ByLondon Speech and Feeding November 26, 2025November 26, 2025

When children find talking hard, parents often face a difficult question: ‘Should we wait and keep encouraging speech? Or introduce something like AAC?’

AAC (Augmentative and Alternative Communication) can sound intimidating, but it simply means any way we support or replace spoken words, from simple gestures and picture boards to high-tech speech-generating devices. Far from ‘giving up on speech,’ AAC often becomes the bridge that helps children find their voice, in whatever form that takes.

💡 What is AAC, really?

AAC is a spectrum of tools and strategies that help people express themselves when speaking is difficult. It might include:

Low-tech supports: Gestures, key word signs (like Makaton), picture symbols, or printed boards
High-tech systems: Apps on tablets that speak aloud when pictures or words are tapped

AAC is not just for children who will never talk. It’s for anyone whose speech isn’t meeting their communication needs right now.

🤔 When to introduce AAC

There’s a common myth that you should only try AAC after ‘exhausting’ other speech therapy options. In fact, AAC can be introduced at any stage, even alongside speech development.

Here are some helpful signs that AAC might support your child:

Your child understands much more than they can say.
They rely on gestures, sounds, or behaviour to communicate.
They become frustrated trying to express themselves.
You find yourself ‘reading their mind’ to interpret needs.
Speech progress feels slow or inconsistent.

If you recognise these patterns, AAC isn’t a ‘last resort’. It’s a communication support, not a replacement for speech.

Recent research consistently shows that AAC does not stop children from talking. In fact, it can encourage speech to develop. A 2024 systematic review and meta-analysis published in the Journal of Autism and Developmental Disorders found that children who received interventions combining naturalistic developmental behavioural approaches with aided AAC showed improved language outcomes, and that AAC ‘does not negatively impact speech development and may even facilitate spoken language growth’ (Smith et al., 2024).

🌉 How AAC supports speech development

Speech and AAC aren’t competing paths: they’re parallel tracks that often feed each other.

Here’s how AAC helps speech grow:

Reduces frustration: When a child can express their needs, they’re more relaxed and ready to learn.
Provides a visual model: Seeing symbols or words while hearing spoken language strengthens understanding and word recall.
Builds consistent language structure: AAC systems follow the same grammar and word order as speech, helping children internalise how sentences work.
Encourages turn-taking and social connection: AAC lets children join conversations even before speech is fluent, giving them more practice in real communication.

AAC is not ‘giving up on speech’. It’s giving a child more ways to succeed while speech continues to develop.

🧩 How to introduce AAC gently and effectively

Start small and meaningful: Begin with a few key messages your child wants to say, not just what adults want to hear. Think ‘I want’, ‘stop’, ‘help’, ‘more’, ‘all done’, ‘no’, ‘again’. These are powerful words for real interaction and autonomy.
Model, model, model: The most important part of AAC success is modelling—using the system yourself as you talk. For example: ‘You want banana 🍌’ and you tap the ‘want’ and ‘banana’ symbols. Children need to see and hear AAC used naturally before they try it themselves.
Use it throughout the day: AAC isn’t a therapy tool to take out once a week. It’s a living part of communication. Model a few words during mealtimes, play, and routines. The more consistently it’s embedded, the more fluent both you and your child will become.
Keep it accessible: If using a device or picture board, make sure it’s always nearby. If it’s in a bag or drawer, it can’t be used in real moments.
Celebrate all communication: If your child points, signs, uses a sound, or taps a symbol, it all counts. Respond warmly and naturally to reinforce communication in any form.

🧠 What parents often worry about

‘Won’t AAC stop them from talking?’: No. Research shows AAC use either has no negative effect on speech or leads to increased spoken output (Smith et al., 2024). When children feel understood, their motivation to communicate grows.
‘What if I model it wrong?’: There’s no perfect way to start. Your effort and consistency matter far more than accuracy.
‘Will they get ‘stuck’ using pictures?’: Some children do continue using AAC long-term; others move naturally toward more spoken language. The goal is always functional communication, not replacing one form with another.

🪞 Bringing AAC into daily life

Here are a few simple, parent-friendly ideas:

Create visual spaces: Post symbols or core words on the fridge, mirror, or play area.
Narrate routines: Use AAC during toothbrushing, dressing, or mealtimes; consistent contexts build understanding.
Pair speech and touch: Always say the word aloud when you point to or tap a symbol.
Involve siblings and friends: Model how they can respond to AAC too. ‘Oh, you said go! Let’s go fast!’
Use shared books and songs: Pause and model key words in stories or songs.

🌱 The takeaway

AAC doesn’t mean giving up on speech; it means opening more doors to communication. When words don’t come easily, AAC gives children a way to connect, share, and be heard.

It helps parents move from guessing to understanding, and gives children the power to express themselves on their own terms.

If you’re unsure where to start, reach out to a speech and language therapist experienced in AAC. Together, you can find a system that fits your child’s strengths, build confidence in modelling, and help every word (spoken or tapped) feel like a step forward.

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.
