Principles of motor learning in Childhood Apraxia of Speech (CAS)

|

We use powerful motor learning principles to help children with CAS (Childhood Apraxia of Speech) learn how to produce better, clearer speech sounds in words, phrases and sentences.

What are these principles?

Principle 1: MASSED PRACTICE

This is where you see a child for lots of sessions in a shorter period of time, so for instance six weeks of three times weekly for 30 minutes.

This leads to motor performance or automaticity.

Principle 2. DISTRIBUTED PRACTICE

This is what I use, as most of my clients are not able to come and see me that often on a weekly basis. It is hard to travel in London and life is hectic. So I favour one session a week over say a term or two terms and a session is usually 45 minutes long.

This leads to improved Motor Learning and good generalisation.

During either Massed or Distributed Practice, we choose between 4 variables:

Principle 3: Constant vs Variable

Principle 4: Blocked vs Random

To explain:

Constant Practice is where we repeat the practice of a small handful of target words.

We practise the same target sound in the same word position, e.g. at the beginning of a word: ‘bee’, ‘bye’, ‘bow’, ‘baa’ or ‘key’, ‘car’, ‘cow’, ‘Kaye’ etc.

We keep the rate, pitch and intonation constant.

Variable Practice is where we vary the rate, volume, pitch and intonation of the targets

We use a larger number of sounds, and words that are motivating to say for the child.

For example, if a child loves Peppa Pig then I might choose the words: ‘Peppa’, ‘Daddy Pig’, ‘George’, ‘Mummy Pig’ and a couple of other favourite characters. My child might struggle with a number of sound sequences there but we will target them one by one.

We can also select simpler words like ‘cape’ and ‘cake’ or ‘tick’ and ‘tip’.

Blocked Practice is where we practise one target word for say five minutes then we move to another target word for the next five minutes and then we revert back to the first target word again and so on, so blocks of practice.

Random Practice means we practise several target words at the same time.

How do I decide on what to use?

Good question!

I always opt for distributed practice (weekly for up to 45 minutes).

Within that, I tend to find it most successful to start out with constant practice when a child is finding a certain sound sequence really hard and we need to just ‘nail it’. Bearing in mind I only pick sounds that my student can actually make in isolation, so we are not working on articulation! (where we focus on trying to elicit single sounds correctly – or even at all sometimes) Here in CAS work, we are working with sounds the student can make but is having trouble to add together, into a sequence that is needed to make a word sound right.

As soon as I feel we have some traction I will go to variable practice, i.e. I pick words that are either funny or interesting for the child and it can be a slightly larger number.

I tend to use blocked practice in the beginning or when working on vowels. That’s because it is more important we get our vowels right. They carry a word and are very important for overall speech intelligibility. Once we are on a roll, I tend to go more for random practice.

Example

Here in the video clip, we try and work the /e/ vowel in short words likes ‘bell’, ’fell’, ‘dell’, ‘sell’, ‘smell’ and I am using an AAC device to give a child’s voice as auditory feedback as well as using the PROMPT approach to help my student shape his vowels.

So this is:

  1. Distributed (1 x week for 45 minutes)
  2. Constant – we are practising the /e/ vowel in the same position in six different words
  3. Blocked – we did this: several repetitions of each word and after the sixth we moved to another sound, and then later we came back to this.

Please feel free to contact me if your child has speech sound difficulties. It is my passion. I love supporting children with apraxia.

    Why ‘Prosody’ Matters in Childhood Apraxia of Speech (CAS)

    Prosody refers to the ‘music’ of speech — the rhythm, pitch, stress, and volume that convey meaning and emotion beyond the literal words themselves. Think about a monotone statement like ‘Really?’ compared to one with a rising inflection, expressing genuine curiosity.

    When I work with children on producing speech sound sequences, we focus on mastering individual sounds and then putting them together into target words. A crucial element that can significantly impact a child’s speech production is ‘prosody’.

    In CAS, where the difficulty lies in planning and executing the motor movements for speech, prosody can be a powerful tool for producing clearer words and phrases.

    Here’s why working on prosody is an essential tool in CAS speech therapy:

    1.  It aids Motor Learning:

    Apraxia of Speech means that the planning and execution of speech movements are impaired. When we use exaggerated intonation or stress patterns while modelling words, we are providing additional prosodic variation and, therefore, additional auditory cues. These cues often help my student to carry out the correct motor movements for a word or syllable sequence.

    For instance, I might say ‘ball’ with a high-pitched emphasis on the ‘b’ sound. This auditory cue might be more effective in guiding the child’s tongue placement than simply repeating the word without variation.

    In this little video clip I get my student to say the word ‘snuggle’ (since we were working on that particular sound sequence: snuggle, snout, snore and sneeze) with a high voice and then a lower voice ‘like a bear’ — again it provides that extra auditory cue, but, in addition, the fun aspect also helps to take away the intense focus on a tricky movement pattern.

    By now the new pathways have been laid through repeated practice and now automaticity takes over and without too much effort my student can suddenly produce a motor pattern. It’s magical when it happens and gives me such a thrill.

    2. It makes speech more engaging and natural sounding:

    Children with CAS often sound robotic or flat due to challenges with prosodic elements. By incorporating variations in pitch, volume, and rhythm during therapy, we can help achieve a more natural flow of speech

    3. It makes it easier to express our emotions:

    Children with CAS often struggle to express themselves emotionally; partly through the difficulty of producing clear words — period, but also in addition due to the difficulties or absence of musicality and rhythm in their speech.

    Therefore, it is so important to incorporate activities focused on practising different emotions with varied intonation patterns. This can really empower our students to put emotions into their words.

    Good words to practise are fun words like ‘Wow!’ or ‘Yeiih’ or power words and phrases like ‘No!’ or ‘Gimme that’ etc.

    Making Therapy Fun and Engaging:

    Speech therapy for CAS doesn’t have to be all drills and exercises (though to be fair sometimes we can’t quite get round to making each and every word huge fun though we try…).

    I aim to make all my sessions fun and have intrinsic rewards built into the speech practice where possible.

    Home practice tips:

    Therapy shouldn’t exist in a bubble. Working on prosody during sessions is crucial, but it’s equally important to integrate these skills into everyday interactions. Parents and caregivers can model appropriate prosody during playtime, story time, or even simple conversations. This consistent reinforcement helps our children to generalise their newfound skills and use them naturally in their daily lives.

    • Sing songs and rhymes: Songs naturally incorporate variations in pitch and rhythm. Singing familiar songs and creating silly rhymes can be a delightful way to practise prosody.
    • Use puppets and toys: Assign different voices and personalities to puppets or toys. This encourages children to experiment with pitch and volume to differentiate characters.
    • Read aloud with enthusiasm: Model expressive reading, varying your voice for different characters and emphasising key words. This makes reading time engaging and helps children understand the power of prosody.

    Understanding phonological processes in 3–7-year-olds: What’s typical and when to seek help

    As a speech and language therapist, one of the most common questions I hear from parents is:

    ‘They can talk, but their speech still sounds immature. Is this normal?’

    Many children between the ages of three and seven use speech patterns that make their words sound different from adult speech. These patterns are known as phonological processes, and for younger children, they are a normal part of speech development.

    However, when these processes persist beyond the expected age, they can start to affect clarity, confidence and learning, especially once children enter school.

    This blog will help you understand:

    • what phonological processes are
    • which patterns are typical at different ages
    • and when it might be time to seek speech therapy support

    What are phonological processes?

    Phonological processes are patterns of sound simplification that children use while their speech system is developing.

    Instead of learning each sound one by one, children initially organise sounds into patterns that make speech easier to produce. This is a normal and efficient strategy for a developing brain.

    For example:

    • saying ‘tar’ instead of ‘car’
    • saying ‘poon’ instead of ‘spoon’
    • saying ‘bud’ instead of ‘bus’

    These are not ‘bad habits’. They are part of how speech develops.

    The key question is how long these patterns last.

    Common phonological processes (and when they usually disappear)

    Below are some of the most common processes parents notice in 3–7-year-olds.

    1. Final consonant deletion

    Leaving off the last sound in a word

    • ‘ca’ for cat, ‘da’ for dog
    • Typically resolved by 3–3½ years

    2. Fronting

    Replacing back sounds (k, g) with front sounds (t, d)

    • ‘tar’ for car, ‘do’ for go
    • Typically resolved by 3½–4 years

    3. Cluster reduction

    Omitting one sound in a consonant cluster

    • ‘poon’ for spoon, ‘top’ for stop
    • Typically resolves by 4–5 years (some clusters slightly later)

    4. Gliding

    Replacing /R/ or /L/ with /W/ or /Y/

    • ‘wabbit’ for rabbit, ‘yion’ for lion
    • Can be typical up to 5–6 years

    5. Weak syllable deletion

    Leaving out unstressed syllables

    • ‘nana’ for banana
    • Usually resolved by 4 years

    If these patterns continue past the expected age, speech can remain difficult to understand particularly for unfamiliar listeners such as teachers, peers, and also Auntie Karen or grandparents who visit once in a while.

    Why phonological processes matter in school-age children

    By the time children reach reception and Year 1, speech clarity becomes increasingly important.

    Persistent phonological difficulties can affect:

    • being understood by teachers and peers
    • phonics and early reading
    • spelling
    • confidence in speaking
    • willingness to participate in class

    Some children become aware that they ‘sound different’ and may speak less, avoid longer words, or become frustrated when misunderstood.

    What’s the difference between a delay and a disorder?

    This is an important distinction.

    • A phonological delay means a child is following the normal pattern of development, just more slowly.
    • A phonological disorder means the child is using atypical patterns, or continuing age-expected patterns well beyond when they should have resolved.

    A speech and language assessment helps identify:

    • which processes are present
    • how many are affecting speech
    • how consistent the errors are
    • and whether intervention is needed

    Signs it may be time to seek speech therapy

    You may want to seek professional advice if your child:

    • is 3½ years or older and still hard to understand
    • is understood well by family but not by others
    • becomes frustrated or avoids talking
    • has difficulty with phonics or spelling
    • uses several phonological processes at once
    • has not made progress despite time and encouragement

    Early support does not mean something is ‘wrong’. It simply helps speech development move forward more efficiently.Research consistently shows that unresolved phonological processes beyond the expected age can impact intelligibility, literacy and confidence (Dodd, 2014; Bowen, 2015).

    How speech therapy helps phonological development

    Phonological therapy is not about drilling individual sounds endlessly.

    Instead, therapy focuses on:

    • helping children recognise sound patterns
    • building awareness of contrasts (e.g. ‘tar’ vs ‘car’)
    • practising speech in meaningful, playful ways
    • supporting generalisation so progress carries into everyday speech

    For school-aged children, therapy is usually structured, motivating and highly targeted and progress can be very encouraging.

    A final reassurance

    Many children with phonological difficulties go on to develop clear, confident speech with the right support.

    If you’re unsure whether your child’s speech is ‘just a phase’ or something that needs attention, a professional assessment can give clarity and peace of mind.

    What to do when words don’t come fast enough

    What to do when words don’t come fast enough

    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:

    1. Reduces frustration: When a child can express their needs, they’re more relaxed and ready to learn.
    2. Provides a visual model: Seeing symbols or words while hearing spoken language strengthens understanding and word recall.
    3. Builds consistent language structure: AAC systems follow the same grammar and word order as speech, helping children internalise how sentences work.
    4. 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

    1. 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.
    2. 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.
    3. 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.
    4. 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.
    5. 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.

    Because when communication is possible, everything else begins to grow.

    The hidden impact of mouth breathing and open mouth posture on 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.

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

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

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

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

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

    What does the tongue actually do during eating?

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

    For mature chewing, the tongue needs to:

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

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

    Children may compensate by:

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

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

    When should tongue lateralisation develop?

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

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

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

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

    Why does this developmental window matter?

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

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

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

    That is why early assessment is so valuable.

    Signs your toddler may have poor tongue lateralisation

    You may notice your child:

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

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

    How can we encourage tongue lateralisation?

    The good news is that the tongue learns through experience.

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

    Hard munchablers

    Examples include:

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

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

    A simple technique that can help

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

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

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

    Every child develops differently

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

    This may include children who:

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

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

    Early intervention makes a difference

    One of the biggest misconceptions I hear is:

    ‘They’ll grow out of it.’

    Some children do. Others don’t.

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

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

    Final thoughts

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

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

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

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

    Unlocking communication: My daily life with the Saltillo 88 Core Board

    Introduction

    As an AAC speech and language therapist who uses the Saltillo 88 Core board every day, I can tell you it’s more than just a communication tool. It’s a doorway to independence, connection, and expressing my students’ unique voice.

    What is the Saltillo 88 and why do I use this one?

    In this blog post, I want to share practical, real-world examples of how I integrate the Saltillo 88 into various daily activities, empowering my students and parents to learn to communicate.

    There are literally hundreds of core boards out there and I have tried many different ones over the years. Which one should I use with this particular client? Should I make up my own? (I have made up tons!) or should I use a ready-made one like the one below which is what this blog is about.

    For me the best ones are boards with a good number of core words (at least 60) so that the board is versatile and can be used across a range of activities. The board needs to have a range of pronouns, verbs, descriptors, prepositions and question words to be useful and to stimulate not just requesting but commenting and asking questions. Another consideration is: can the board easily be transferred to a more robust AAC system. Once my student is used to the symbols and where they are could we move to an electronic talker/device. And if this answer is ’yes’ then we have a great board to get started with.

    Below is a picture of the Saltillo 88.

    It has 88 words and I find it really does suit most activities. The same board and design is also then found on the TOUCHCHAT AAC device which can be a seamless transition for our learner.

    Let me dive into how core words/board or AAC can be used daily:

    1.  Getting dressed

    Whilst choosing clothes for your little one and getting them ready for the day you can use the following words: want, like, get, finish. Always pack the words into little phrases you can speak naturally when using a board. I have tried to show you phrases that you could use below.

    The words in bold are the core words on the board and the other words are just words you say whilst pointing to the core word.

    • Goal: Express choices, needs, and preferences about clothing.
    • Ideas:
      • ‘I want this one [specific item of clothing: ‘shirt’, ‘pants’]’
      • ‘I like that one [colour/type of clothing]’
      • ‘Help me [put/get it on/take off]’
      • ‘let’s get your socks now’
      • finished let’s go’ (when dressed)

    2. Having a shower/bath

    • Goal: Bath time tends to happen daily and so it lends itself to using the same useful phrases and words to chat about temperature preferences, to ask for toys or for washing routines.
    • Ideas:
      • ‘let’s go have a bath/shower’
      • ‘let’s turn on the tap/water’
      • now turn it off
      • ‘let’s get/have more toys/water/bubbles/tickles’
      • all gone, what’s next?’
      • ‘how about washing your hands/feet’
      • ‘let’s do that again’
      • ‘need some help?’
      • Stop it now, let’s do something different’

    3. Mealtimes

    • Goal: Mealtimes can be (or should be) enjoyable and motivating to ask for specific things we like, and commenting about our eating experiences.
    • Ideas:
      • ‘I want/give me [food item: ‘apple’, ‘bread’]/[drink item: ‘water’, ‘juice’]’
      • More foods/drinks/snacks’
      • All done
      • ‘that’s messy we like that (not)’
      • ‘Like’/‘Don’t like’
      • Big’/‘Little’
      • ‘this is so nice!’

    4. Playing

    • Goal: This is where it’s at for children of course and we can use our core words to chat and engage with our little learners.
    • Ideas:
      • ‘I want play’
      • Go’/‘Stop
      • More/again’
      • ‘not it’s my My turn/’it’s Your turn
      • ‘that’s a Big one!’/‘let’s do Little bubbles (describing toys)
      • ‘let me Open it for you (for boxes, doors in play)
      • ‘I See it’ (to draw attention)
      • Help me’ (with a tricky toy)

    5. Opening boxes/doors/etc

    • Goal: Most kids love opening boxes, doors and cabinets to see what there is to play with. Help your child to ask for what they want.
    • Ideas:
      • let’s Open that box/bag/zip/door’
      • get me a (toy) out of here’
      • ‘Let’s Take it out and see what it is?’
      • finished’ (when finished with the task)
      • ‘I want [what’s inside]’
      • ‘What’s next? Let’s see’

    Tips for using AAC effectively

    • Consistency is key: Emphasise using it regularly, even for small things.
    • Modelling: this is crucial, the adults need to use the board for all situations first and foremost before we can expect our child to be interested.
    • Patience: Communication takes time and practice.
    • Celebrate successes: Acknowledge every communicative attempt.
    • Make it accessible: Keep the board within easy reach at all times.

    Conclusion

    If you’re considering the Saltillo 88, or TouchChat, or are already using it, I hope these examples inspire you. It’s a journey of discovery, and every word communicated is a step towards a more connected and independent life. What are your favourite ways to use the Saltillo 88 or which core board do you love using? I would love to hear your comments and stories.
