AAC Systems and Speech and Language Development

ByLondon Speech and Feeding November 3, 2023November 3, 2023

Introduction

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

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

Fear not

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

I totally get it!

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

Alternative and Augmentative Communication (AAC)

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

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

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

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

Personal experience

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

Acceptance

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

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

The purpose and nature of a speech and language therapy assessment
ByLondon Speech and Feeding May 27, 2025May 19, 2025
If you have ever wondered what happens when you bring your child to a speech and language therapy assessment, then this blog will shed light on the ins and outs of it for you.

At its heart, a speech and language therapy assessment is a systematic and thorough evaluation of your child’s communication or eating/swallowing abilities. It’s more than just asking a few questions. It is a carefully constructed process designed to identify strengths, pinpoint challenges, and ultimately pave the way for effective intervention.

Establishing a detailed profile – a few bullet points:
- Identification of communication and swallowing difficulties: I aim to determine if a communication or swallowing disorder exists. I will establish if the difficulty is a delay or a more complex disorder.
- Diagnosis of the specific disorder/autism: The assessment delves deeper to pinpoint the specific type and nature of the difficulty. For instance, is your child’s language delay due to a specific learning disability, a developmental delay, or another underlying condition?
- Knowing the aetiology or what is causing a difficulty is crucial for targeted intervention. And whilst we are on the topic let’s talk about an autism assessment: I am trained and experienced in assessing and diagnosing autism. However, when it comes to the diagnosis of autism I provide a preliminary ‘working hypothesis’ rather than giving a definite final diagnosis. The reason for this is that it is considered the ‘gold standard’ and ‘best practice’ to diagnose autism in a multi-disciplinary setting and context. Since I work on my own, I always refer to highly recommended multi-disciplinary clinics for the ultimate diagnostic assessment.
- Determination of severity: Understanding the severity of the difficulty is essential for prioritising intervention and measuring progress. Is your child’s difficulty mild, moderate, or severe? This helps me choose a particular approach and then tailor it to suit each individual child.
- Identification of underlying strengths and weaknesses: An assessment doesn’t just focus on what’s wrong. It also highlights your child’s strengths and areas of relative ease. This information is invaluable for building upon existing skills during therapy. Understanding weaknesses provides specific targets for intervention.
- Guiding intervention planning: The assessment provides the crucial information I need to develop an individualised intervention plan. The findings directly inform the selection of therapy goals, strategies, and techniques. Without a thorough assessment, therapy would be a shot in the dark.
A multi-faceted approach

A speech and language therapy assessment is not a ‘one-size-fits-all’ procedure. The specific tools and techniques used will vary depending on a child’s age, the nature of the suspected difficulty, and other relevant factors. However, most comprehensive assessments incorporate several key components:
- Case history: This involves gathering information about your child’s developmental, medical, social, and educational background. We will go through all the relevant milestones and throughout the process I will make notes which will help bring all the puzzle pieces together.
- Observation: I will observe how parent and child play together and we also look at how the child plays by themselves. Additionally of interest is how a child plays with me, the therapist. Through discussion I will also endeavour to find out how your child plays with other children, be it at the nursery or within the family.
- Standardised assessments: These are commercially available tests with specific administration and scoring procedures. They provide norm-referenced data, allowing to compare the individual child’s performance to that of his or her peers. Examples include articulation tests, language comprehension and production tests, and fluency assessments. I tend not to use these assessments a lot.
- Instead, I use non-standardised assessments: These are more flexible and allow to probe specific areas of concern in more detail. This might include language samples (analysing spontaneous speech), dynamic assessment (testing and teaching to identify learning potential), and informal observation of play or interaction.
- Immediate feedback and report writing: During and thenfollowing the assessment, I will bring all the gathered information together and I will discuss with the parents what my findings are and what my recommendations in the short term are. Parents always go home with a good handful of useful strategies that they can implement at home right away. In addition, I provide a comprehensive report outlining the findings, diagnosis (if applicable), severity, strengths and weaknesses, and recommendations for intervention.
In conclusion, a speech and language therapy assessment is a dynamic and essential process. It is a journey of discovery, aiming to understand a child and the child’s family and his or her unique communication or feeding profile. The assessment is usually the start of our wonderful learning journey together.

Below is a short video clip of an assessment where you see me in action explaining a particular therapy approach to a set of parents. It perhaps shows a tiny bit of how relaxed we are in our sessions and that assessment is not at all daunting, but a hugely informative event overall which will leave you feeling empowered and hopeful.

What happens after an assessment?

Please feel free to get in touch with me via my contact form if you wish to have an assessment for your child’s communication difficulties or feeding difficulties.

An assessment is always a stand-alone event and does not mean you need to automatically book follow up sessions at all. It will give a lot of information and based on this you can decide if you would like more therapy or follow up for you and your child. Many times ongoing therapy is not needed! I only recommend a course of therapy if it is really needed and where it would be immediately beneficial for your child.

Explore how Intensive Interaction develops Autistic children’s communication
ByLondon Speech and Feeding July 31, 2023June 21, 2023
Intensive Interaction is an approach that I might suggest for your child. Here is an overview of this approach to increase your knowledge. There are a range of approaches that overlap and having trained in them all I use them all interchangeably to tailor to each child individually. This approach is particularly good for children who work mostly to their own agenda and find it hard to engage with others.

So, what is Intensive Interaction?

According to its founder, Hewett (1980), the approach “involves mirroring a person’s actions, sounds and facial expressions.” This allows your child to recognise and form communication between themselves and another, in a fun, play-based setting. Attention and listening are the fundamentals to speech and language development. By using the Intensive Interaction approach, we can increase the time your child can attend for and with another person. We are working towards a child enjoying another person’s presence. We are hoping to make gains with playing together with a child, taking turns and achieving reciprocity. That is the platform which we need to start with to build communication, language, words and perhaps even speech.

There are many aspects that this approach supports:
- such as using facial expressions
- being in the presence of other people
- having a shared space
- attending to others
- recognising and using non-verbal behaviours (e.g., gestures)
- making sounds/noises (vocalisations) that have meaning
- and eye contact. Although, we must be careful when suggesting ‘improving’ the use of eye contact. For some individuals making eye contact can be physically painful. So be aware that we are not making our children ‘look’ we are encouraging their natural behaviour.
Who benefits from Intensive Interaction?

Children with more complex communication and learning delay can benefit from the Intensive Interaction approach. Each session can be adapted to the needs of the individual and the sessions can be designed to use the whole or part of the approach. It is especially useful for children who are finding it hard to engage in any way socially with another person. Autistic children who tend to work to their own agenda often benefit from this approach.

How is Intensive Interaction implemented?

You need to have an environment that your child is comfortable in, and to be able to come down to their level so that you can see each other. This is why I often visit children in their own homes to ensure that they are comfortable and that they can withdraw for periods of time if they need to as well.

Ensure your child knows you’re there and you are 100% present. This is very important. I would recommend that you put your phone away for some 10 minutes or so and give your undivided attention to your child for that period of time.

Waiting

Waiting is very important: we need to give your child time to process what is happening around them. After waiting for a response, you might want to start copying any gestures they use, any facial expressions they make, or perhaps imitate any sounds. You’ll want to continue with this for a few minutes to see if the communication between you and your child changes. Remember always take the cues from your child; if they communicate a message with you, respond. It might be that they are ready to finish and that they’ve shown this by walking away or signing.

Giving your child a way to respond is vital. We can use visuals to support their communication. We can create ‘yes’ and ‘no’ symbols so they can use them in a functional way.

A top tip in these sessions is to use mirrors, so that your child can see and begin to recognise their own facial expressions.

There are other programmes that overlap with Intensive Interaction such as Hanen with following your child’s lead and the Gina Davies Curiosity Programme.

Now you know a bit about Intensive Interaction, why not book a call to discuss how we can support your Autistic child’s communication using this evidence-based approach.

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.

Discover speech and language regression in autistic children and how you can support your child
ByLondon Speech and Feeding February 17, 2023January 3, 2024
There’s often this idea that autistic children have extensive vocabulary and knowledge, but this is not always the case. In fact, 30% of autistic children have language regression.

Goldberg (2003) suggested that speech and language regression refers to the decline in a young child’s speech and communication abilities. We know that regression in speech, language and communication skills often occur before the age of two years. 25% of autistic children develop language at word level between 12 and 18 months of age before losing this language they have learned. As you’re probably aware this regression in communication is a diagnostic indicator of Autism.

We understand that you want your child to progress, and you struggle to watch as their frustration grows as you feel helpless. I want to provide you with tips so that you can feel empowered to support your autistic child and reduce the impact their communication skills have on the family.
1. Reduce frustration by providing visuals to support their communication
2. Model gestalts. We know that autistic children are often gestalt language processors. Learn more about gestalt language processors in one of my previous posts.
3. Praise the ability to communicate. Focus on what they say not how they say it. E.g., good listening, nice talking.
4. Provide your child with choices (using real objects to represent your choices). E.g., do you want an apple or banana?
5. Your child must be motivated and have a purpose to communicate. So, ensure you use highly motivating objects for conversations
6. Provide them with opportunities to communicate. We need to teach children that if they want something, there’s a process that you need to have the opportunity to ask for it. We find that if parents understand what their child wants (without them asking), the object is given to them, and so there’s no reason for your child to ask.
7. There’s this idea that we need to teach children eye contact. This is not always the case. Your child is unique, we do not want to take their unique skills away.
8. Model words which are concrete. E.g., words such as ‘finished’, ‘more’. You can model these several times within the day. You can use a gesture to make the word more visual (see the images below). We know that autistic children are often visual learners.

Remember that if your child has speech, language and communication regression, it doesn’t mean your child will stay static.

It’s vital that you seek support from a qualified Speech and Language Therapist. We can tell you at what point in the communication development that your child is at. And we can support you through the process. We can provide you with an individualised plan specifically for your child to ensure you maximise their potential.

Ages and Stages: 0–3 months
ByLondon Speech and Feeding December 18, 2024December 11, 2024
Designed by Freepik

What do we offer our babies from 0–3 months old? What toys? What are the best early activities for our baby to develop? I get asked this a lot so here are my suggestions.

You are the best toy

You the parent or the caregiver are the BEST toy a baby could have in the first three months. The most important thing is to talk and sing to your baby, to look and hold your baby and offer your face and voice! Use sing song intonation as much as you can, and as often as possible. We know that babies respond really well to interesting voices, singing or funny sounds. Use your facial expressions!

It is important to encourage early turn taking: leave pauses in between what you say or sing to allow your baby to respond to you. Once you see any signs of your baby responding you continue as if you are having a conversation.

Visual Stimulation

We know that baby’s eyesight still needs to develop in those first months and that a newborn can only distinguish light, shapes and faces. And their distance vision is blurry in the first month. A baby can see up to 15 cm away and this is roughly the distance between the feeders’ face when bottle or breastfeeding the baby.

Black and white

Your baby can see black and white and some shades of grey. So, in the first month you really will need no toys at all other than your face and your voice, your smile, giggle and your hands! Of course, there are a range of black and white visual toys available these days like the ones below. But if you are on a budget, I would say you don’t need those.

From the second to third month a baby can begin to follow objects with their eyes. They recognise a familiar face and now they start reaching for things. Their colour vision is also gradually improving.

Baby gym

One of the best early toys is a ‘baby gym’ where bright and colourful toys dangle off foam padded arches. You can sometimes get ones with a mirror hanging off one of the arches or a mirror sewn into the mat. This is useful as baby likes to look at his/her face at around three months old and this can also be great for tummy time. If you are on a budget this would be the one toy, I would recommend you to get.

If there is no mirror on your baby gym you could get a mirror toy. There are lots out there, this one is a good example. I would probably get a mirror toy that has other sensory components attached so you get more value for money, i.e., three toys in one.

O-ball

Another great toy to get around 2–3 month is an O-ball for easy grasping, bright colours, very lightweight.

Sounds

Lovely early toys are sound makers, bells or rain makers. Some very light weight bells can be attached to your baby’s ankles and they ring every time your baby moves his/her legs. This is a nice and easy introduction to early cause and effect understanding.

Peek-a-boo

A great early game is Peek-a Boo and you could complement your hands hiding your eyes with some nice lightweight pieces of material like a piece of organza veil fabric for example. An added benefit is that later on baby can try and grasp the materials and pull them out of the container.

Music

Music is very important. Turn on the radio to classical or any easy listening station you like. If nothing else you could sing of course! And do not worry about not hitting the right notes your baby won’t judge you (until they are about three years old!)

Designed by Freepik

After three months

At the end of three months your baby is likely to show you the following:
- makes cooing and early babbling sounds
- seems to know your face
- smiles at you socially
- cries for different needs: hungry, bored, needing attention, looking for you
- opens and closes hands to try and grasp items
- takes swipes at dangling
- kicks his/her legs
- looks at faces and toys, lights
- turns his/her head towards sounds
- starts to understand the world around him/her.
Don’t panic!

But don’t panic at all if you feel your baby has not quite mastered any of those stages. Chances are they are doing so very soon. If you are worried, please do come and bring your baby to our clinic for a screen and we will give you plenty of assurance and ideas on how to help your baby move forward.

On a final note, Early Intervention is key and bringing your baby for a one-off consultation to a speech and language specialist is always a great idea, just to get ideas, to see that baby is on track and to help baby develop.

The earlier you bring your baby the better. Chances are one consultation is all you need and perhaps a six-monthly review to just stay nicely on track.

Look out for my next Ages and Stages from three to six months old!

I look forward to seeing you! Get in touch with me via my contact form.

Childhood Apraxia of Speech: Signs and first steps (2–5 years)
ByLondon Speech and Feeding February 9, 2026February 6, 2026
If you’ve found yourself wondering ‘Why can my child say a word one day, but not at all the next?’ it might be that your child has a motor speech difficulty. This means the challenge isn’t that your child doesn’t know what they want to say; it’s that their brain finds it harder to plan and coordinate the movements needed for clear speech. This speech difficulty is called Childhood Apraxia of Speech (CAS)

In this post, I’ll explain what CAS can look like in 2–5 year olds, what an assessment usually involves, and what you can start doing at home to support your child without turning life into ‘speech homework all day long’.

What is childhood apraxia of speech (CAS)?

Children with CAS often have lots to communicate about (and strong ideas!) but their speech may come out as:
- Unclear
- inconsistent
- hard to ‘copy’ on demand
- frustrating for them and for you
CAS is not caused by laziness and it is not a parenting issue. It is also not something children simply ‘grow out of’ without support. But with the right therapy approach, children can absolutely build clearer speech over time.

If you’d like to read more about verbal dyspraxia, you may also find this helpful: Supporting children and families living with verbal dyspraxia.

Why is CAS such a big topic right now?

Many families come to me after months (or years) of being told:
- ‘She’ll talk when she is ready’
- ‘He’s just shy’
- ‘It’s probably a speech delay’
- ‘It’s normal for toddlers’
And sometimes it is a general delay. But sometimes it’s something more specific, like CAS.

There’s also been a huge rise in parents seeking information online, and CAS is often mentioned alongside speech sound difficulties such as:
- phonological delay (pattern-based speech errors)
- articulation difficulties (one sound that won’t come out clearly)
- inconsistent speech disorder
These can look similar at first glance, which is why a specialist assessment matters.

Signs of childhood apraxia of speech in 2–5 year olds

Children develop speech at different rates, and not every unclear speaker has CAS. But here are some common features that may raise a flag, especially when you notice several together.

1) Inconsistent speech errors

Your child might say the same word in different ways:
- ‘banana’ → nana / baba / mana
- ‘daddy’ → gaga / daddy / dadi
This inconsistency is one of the biggest clues.

2) Difficulty copying words on request

Some children speak more easily in natural play, but when asked ‘Say ___’, they freeze or the word becomes much harder.

3) Limited sound repertoire

They may use only a small set of consonants (like /M/, /N/, /B/, /D/) and avoid others.

4) Vowel distortions

Many children with typical delays mainly struggle with consonants. But in CAS, vowels can also sound ‘off’ or change between attempts.

5) Speech that sounds effortful

You might notice your child:
- pauses between sounds
- tries multiple times
- looks like they’re ‘searching’ for the right mouth movement
6) Longer words are much harder

‘Car’ might be easier than ‘carry’, and ‘carry’ easier than ‘caterpillar’.

7) Prosody differences (rhythm and stress)

Some children with CAS sound a little unusual in their speech rhythm, stress, or intonation.

8) Frustration or reduced confidence

When a child is frequently misunderstood, they may:
- talk less
- use gestures more
- become upset when asked to repeat themselves
Important note: none of these signs alone prove CAS but they are a strong reason to seek a speech assessment rather than waiting.

CAS vs phonological delay vs articulation difficulty (quick guide)

These are some of the most common questions I hear.

If it’s mainly an articulation difficulty…

A child may consistently say one sound incorrectly (for example, ‘thun’ for ‘sun’- lisp- but everything else is developing well.

If it’s mainly a phonological delay…

You might notice clear patterns, like:
- leaving off the ends of words (‘ca’ for ‘cat’)
- swapping back sounds for front sounds (‘tar’ for ‘car’)
Patterns are often consistent and respond well to phonology-based therapy.

If it might be CAS…

Speech often feels less predictable, harder to imitate, and more impacted by word length and complexity.

If you’re unsure, that’s completely normal, and exactly why assessment matters.

What happens in a CAS assessment?

A high-quality speech assessment for possible CAS usually includes:

1) Parent discussion and developmental history

We talk about:
- pregnancy and birth history (where relevant)
- feeding history
- early sounds and babbling
- first words and how speech has progressed
- family history of speech/language needs
2) A speech sound assessment

Your child might be shown pictures or play-based prompts so we can hear:
- what sounds they can say
- what they simplify
- whether errors are consistent or inconsistent
3) An oral-motor and movement check

This isn’t about ‘strength’. It’s about coordination and planning. We look at how your child manages speech movements and transitions.

4) Stimulability testing

This means: how easily can your child learn a new sound or word with support?

For CAS, we often explore how they respond to:
- slowed-down speech
- visual cues
- rhythm/tapping
- short, simple syllable shapes
5) Functional communication and confidence

We look at how speech impacts daily life:
- being understood at nursery
- joining in with peers
- asking for help
- managing emotions when misunderstood
At the end, you should leave with:
- a clear explanation of what we think is going on
- a therapy plan
- practical home strategies
- realistic next steps
What parents can do at home

Here are CAS-friendly strategies you can start right away.

1) Choose ‘power words’

Pick 1–2 words that matter most in your child’s daily life, such as:
- more
- help
- mummy
- again
- stop
- open
These words are motivating and functional.

2) Keep it short and successful

For many children with CAS, the goal is quality over quantity.

Try five minutes a day rather than 30 minutes of struggle.

3) Support speech with rhythm

Some children benefit from:
- tapping a beat on the table
- clapping syllables
- using a gentle ‘marching’ rhythm
This can help the brain organise the sequence of movements.

4) Celebrate approximations

If your child says ‘moh’ for ‘more’, that’s communication!

We want them to feel:
- safe
- understood
- proud to try again
Confidence is a key part of progress.

A short parent story (anonymised)

One mum said to me:

‘We kept being told to wait. But I could see my child understood everything; they just couldn’t get the words out. Once we had an assessment and a plan, it felt like we finally knew what to do. The biggest change was his confidence. He started trying more.’

When should you seek support?

You don’t need to wait until school.

It’s worth getting an assessment if your child is:
- hard to understand compared with peers
- becoming frustrated or withdrawing from talking
- inconsistent with words they used to say
- struggling to imitate speech sounds
- showing signs that match CAS
Early support can reduce stress for the whole family and help your child feel successful in communication.

Here’s how I can help:

✅ A detailed speech assessment (including whether CAS is likely)

✅ A clear therapy plan with realistic goals

✅ Practical home strategies you can use immediately

✅ Support for nurseries and schools (where needed)

✅ In-person sessions in North-West London and online options

Final gentle reminder

You are not overreacting. Trust your instincts.

Your child is communicating the best way they can, and with the right support, speech can become easier, clearer, and more confident.
