Childhood Apraxia of Speech: Signs and first steps (2–5 years)

| |

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

Book your consultation here.

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.

    Five ways to increase confidence and reduce frustration in children with speech and language and communication difficulties

    An orange speech bubble with a testimonial

    Your child’s speech, language and communication difficulties may impact their self-esteem. And they may show signs of increased frustration. You want them to be full of confidence, increasing their participation in school and fully engaging with their peers.

    1. Practise active listening

    Speech difficulties can mean that it’s more challenging to understand what your child says. It’s important to show that you’re paying attention, giving them time to express themselves. Focus on what your child says rather than how they are speaking. Remember to maintain eye contact, and actively listen. Active listening and giving time can be trickier than it sounds. I can provide strategies to support your active listening skills.

    2. Give other means and forms of communication

    Allowing children to express themselves in a variety of ways (e.g., gesture, signs, written, use descriptions to describe a word (e.g., sand – you find it out the beach, it can have pebbles on it, it’s not the sea), use of symbols or high-tech augmentative communication methods such as a computer). Using different ways is vital in reducing frustration and communicating their message. If you’re unsure of what other forms of communication you can use, please contact me for some top tips.

    3. Praise efforts

    Providing specific praise allows your child to understand what they’ve achieved. E.g., you could praise the way your child listens, or how they take turns, or their resilience (e.g., “I like the way you listened” or “good listening”). Think of different ways you could praise you child during different activities, so you are prepared with phrases that you can use.

    4. Have clear start and end points in activities

    Some children with speech, language and communication needs have difficulties with transitioning from one activity to another. They also have difficulties with changes in routine. This can add to their frustration and changes in behaviour. So, how do you show a clear start and end to an activity? You can have a visual timetable, or you could have ‘start’ and ‘finish’ boxes where you place all the materials in the box labelled ‘start’. And once the activity has finished, you put the items in the box labelled ’finished’. If you need support with transitions, please contact me.

    5. Use visuals

    Visuals can support your child to understand routine and spoken language. Visuals can range from symbols to online images, to photographs, or a combination. Explore which type of visuals work well for your children. Using visuals can be powerful if used correctly. Make the most of the opportunities that visuals can provide for your family.

    Increase confidence and reduce frustration in children with speech and language and communication difficulties today. Please feel free to contact me if you need any support or tips on maximising these opportunities.

    How do we play with our Gestalt Language Processors?

    Image by Freepik

    Child-led therapy

    When working with Gestalt Language Processors, it is always advisable to use child-led therapy. What does that mean? Child led therapy involves following a child’s interests and allowing her/him to lead the play activity throughout the speech and language therapy session. In other words, instead of having my own ideas of what we might want to play with or what activities I might try and use, I provide a range of toys I know the child likes or has played well with before; then I wait for the child to pick what she/he enjoys doing.

    Play can be very repetitive and we can often see our child cycling back to the same one or two toys throughout the session. But this is what she/he needs to do at that time and it means that we have focused attention and engagement. This in turn is very helpful for the therapeutic process, which is to offer great scripts and phrases/words alongside what she/he is playing with.

    Monotropic minds

    Often the mind of autistic children is more strongly pulled towards a smaller number of interests or hobbies as I like to call them. Dr Dinah Murray, Dr Winn Lawson and Mike Lesser have found in 2005 that autistic people have ‘monotropic’ minds. They explain that autistic children focus their energy on a narrow range of activities as the energy required to switch between several toys is much higher than we would see in the neuro-typical population.

    Gestalt Language Processors are often also Gestalt Cognitive Processors. This is when experiences are retained as episodic events and memories. An event is remembered by specific parts of the same event. And, therefore, these specific parts should always be part of that event, when the event is repeated.

    Should any of the specifics be changed or are missing, then this can cause great upset to Gestalt Cognitive Processors. So, for example, if the last two times in speech therapy we had the train set out and this was played with happily, then this becomes a specific part of the whole session. If, I then don’t offer the train set the third time a child comes to see me, this could be very upsetting.

    This is why I tend to try this out and see what happens. Usually in the 3rd or 4th session: I might not bring out the car run that has hitherto been super successful to see if we are able to transition well to other toys. If yes, then we can have new experiences but if not then I will re-offer the car run/or whatever toy pretty quickly so as not to cause complete dysregulation.

    A few pointers below which help with child-led play:

    Introduce a few new toys and see what happens

    Parents are encouraged to bring some familiar toys their child likes to the session. We can then introduce a couple of different toys to see how we go. Try offering a new toy alongside the familiar one; try offering new toys without the familiar one present, but be prepared to re-offer the “old” toy should our child get upset.

    Rotate toys and don’t offer out too many toys

    I find that children can get overwhelmed and overstimulated by too many items out all at once. I always talk to parents about toy rotation at home and I encourage storage and ‘tidy up’ of toys so that we can increase attention focus, and also maintain freshness and new interest in older toys.

    Some children are not yet ready to play with toys

    Here I suggest people games: these are games where the adult becomes part of a more motor-based activity. Some call it ‘rough and tumble play’ but it can be nursery rhymes such as sleeping bunnies/row row the boat or peek-a-boo for the younger ones.

    Copy/Imitation is so important – try getting two identical or similar play items

    When we are copying our child, it is often not desirable to ‘take turns’ with their toys/blogs/cars etc as our child may not be ready to let us take a turn. Instead, if we have the exact same toy that our child is having then we can play alongside our child and copy them perfectly without interrupting their play.

    Speech Sound Challenges: A focus on /L/ and /Y/

    Have you ever thought about how difficult it can be to produce certain speech sounds? Some sounds are definitely trickier than others. This is especially true for children with speech sound disorders like Childhood Apraxia of Speech (CAS).

    My student with CAS has been working hard on producing the /L/ sound especially when it was followed by an /O/ or /OO/ like, ‘log’ or ‘look’. We’ve practised lots and now that he’s got a good handle on /L/, he’s started replacing another difficult sound, /Y/, with it. So, ‘yes’ becomes ‘less’ and ‘yuck’ becomes ‘luck.’

    This is a common pattern in speech development. Once a child masters a new sound, they may start using it in place of other sounds they find even more challenging.

    Minimal Pair therapy

    I use different evidence-based methods to help my students. And I often like to start out with phonemic awareness and then I move to contrasting the error sound with another sound to make completely different words. This approach is called ‘minimal pair’ therapy: both words are the same except for the initial/final sound which has the error sound, and this is contrasted with the correct sound.

    Below is an example of this:

    After we have worked on sound awareness, listening and becoming aware of small units of sound matter, then we can move to working on tongue placement and movement.

    Tongue placement and movement to produce correct /L/ and /Y/ sounds

    To produce these sounds correctly, the tongue needs to be in specific positions and make specific movements.

    • /L/ sound:
      • Tip of the tongue touches the alveolar ridge (the bony ridge behind your upper teeth)
      • Sides of the tongue are raised to the sides of the upper teeth
      • Airflow escapes through the sides of the tongue
    • /Y/ sound:
      • Tip of the tongue touches the roof of the mouth behind the alveolar ridge
      • Sides of the tongue are raised to the sides of the upper teeth
      • Airflow escapes through the centre of the mouth

    I also use:

    • Auditory bombardment: Auditory bombardment is a technique that involves repeatedly listening to a target sound. This can help children to develop a better understanding of the sound and how to produce it.
    • Visual cues: Visual cues can be helpful for children who are having difficulty producing a particular sound. Here I use the image of a ‘standing tongue’ versus a ‘sitting tongue’.
    • Physical cues: I use my hands to show a ‘standing tongue’ for the /L/ versus a ‘sitting tongue’ for the /Y/. But what worked even better and sadly I don’t have the video clip for it:
    • Semantic cues: For example a picture of an ‘EAR’ to make the sound /Y/ so we shape the sound /EA/ to /Y/.
    • Parent involvement: Parents play an important role in their child’s speech sound development by providing opportunities for them to practise their speech sounds at home. This can be done through activities such as reading books, singing songs, and playing games.
    • Reinforcement: It is important to praise children for their efforts, even if they are not perfect. This will help them to feel motivated to keep practising. Important here for speech correction is concrete reinforcement: I feed back to my student what exactly they were doing correctly with their tongue or lips. Rather than saying ‘well done’, I mention what my student has just done with the tongue to change the sound: ‘I saw you lowered your tongue! That made a good /Y/’.

    Another great way of reinforcing positively is to ask the student how they feel they have done? For the older ones I often ask them to self-rate their sound production out of 10. Then we can work towards the next incremental number upwards. This is very effective and gives the student control over their own work.

    Please contact me if your child has speech sound difficulties.

  • Using AAC – Augmentative and Alternative Communication for non-verbal and early verbal children

    Using a Core Vocabulary Board

    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.

    Using a Core Vocabulary Board

    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!

    Using a Core Vocabulary Board

    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.

    Transforming Mealtimes

    Speech Therpaist in London

    Transforming Mealtimes

    Below are two reviews I got from grateful clients over the past 4-6 weeks; this blog is more about how Feeding Therapy can help you than blowing my own trumpet…. though that said, it is always so nice and gratifying to hear when parents are happy and hopeful about their little one’s feeding journey. Feeding Therapy is a substantial part of my work as a Children’s Speech and Language Therapist. One of my specialist subjects is Autism and we find that many children on the Autism Spectrum are very specific about eating, and will often refuse a range of typical family foods in favour of a narrow range of foods/snacks.

    Mostly, feeding difficulties are a combination and complex cocktail of factors that have contributed to the current status quo: sure, there may have been some physical problems to start off with, such as reflux causing the baby discomfort, constipation, a very tight tongue tie or a swallowing problem caused by neurological difficulties and of course sensory processing difficulties are also very physical experiences. We always begin with a very thorough case history taking and information gathering, followed by an oral assessment and observation of the actual swallow to establish what might have been – or still might be – the cause for the feeding difficulties.

    In most of the cases I see in my practice, the original obvious cause is no longer present, especially with older children. So, if the swallowing is fine, the reflux is no longer present, the tongue was divided (twice!) why are they still not eating much, refusing to try new foods, only accept certain textures etc.

    The answer is extremely complex and multi-faceted and this little blog is not covering any factors in detail (we would be here all night) -I mentioned sensory processing difficulties earlier on. These are mostly still present but often not acknowledged or recognised by parents. And it is certainly the case that one of the contributors is parental anxiety; this tends to run very high and has been for many months, sometimes years. This in turn often leads to very tense and unpleasant, endlessly long meal times and many times children are force-fed several times a day in order to “get something down there” as otherwise they would probably starve themselves.

    Additionally, parents end up only offering a very narrow range of foods because that is all their child will eat. This ends up in a vicious cycle of children being fed porridge-style food for all meal times and of course they won’t progress to more mature foods if these mature foods are never on offer.

    In order to help address and disentangle some of the issues I often introduce the “Division of Responsibility in Feeding” as researched and recommended by Ellyn Satter (The Satter Feeding Dynamics Model)

    Here are the main points of her approach:

    Children have a natural ability with eating, they eat as much as they need and they grow in the way that is right for them and they learn to eat what their parents eat. (E Satter). The parent is responsible for WHAT the child eats, WHERE and WHEN the child eats. The child is responsible for HOW MUCH they eat or WHETHER to eat. Satter proposes that parents should guide their child’s transition from nipple feeding through semi-solids, then thick and lumpy foods to finger foods and then on to normal family meals.

    Please note: this model is only appropriate for children where the original physical cause is no longer present!

    Of course it’s not easy! It requires a huge shift in thinking about feeding and it requires to trust our children to know what is best for them. This is very big for most parents, as it is not how we were brought up and it is not commonly known that babies and children know what is good for them!

    However, it is certainly true that parents who follow this particular approach and make small, steady changes in the way the offer foods, and in the way they create family meal times differently, children make very nice, pleasing progress and over some months we often see remarkable positive changes.

    I like to work in a team and especially for this type of problem it is essential to have a multi-disciplinary approach. A knowledgeable dietician is an enormous plus in any feeding team as is of course a

    Paediatrician and/ or a Gastroenterologist and the most important people in the team are the parents!

    Feeding Therapy is all about collaboration and a ‘team around the child” approach. When we have this in place and there is trust amongst the team members then we make fantastic progress.

    Do get in touch with me if you would like some help with your tricky feeder.

    Lovely Reviews

    I visited London Speech and Feeding a couple of days ago with my 8-month-old granddaughter and her mother. Sonja made us feel comfortable and at ease from our first introductions. She was able to pinpoint my granddaughter’s mum’s anxiety around weaning very quickly. She not only gave her the tools to do this successfully, but also really encouraged my granddaughter’s mum and instilled confidence that she had everything she needed to make this sometimes-difficult transition without further anxiety.

    Sonja was very thorough in her initial assessment of my granddaughter’s physical milestones and her developing speech. My granddaughter felt very comfortable with Sonja and happily played along with her. Then came the big moment – trying out various foods! We were amazed to see just how easily my granddaughter, with Sonja’s expert encouragement, took to sampling the wonderful array of different delicious morsels Sonja had prepared for the session. My granddaughter even drank from a cup for the first time! Wonderful!

    Sonja then emailed a summary of the session and an extensive array of resources with suggestions for my granddaughter’s mum which she has now put into action. My granddaughter’s mum couldn’t thank Sonja enough for her caring attitude, extensive knowledge, and warm professionalism. I have no hesitation in recommending Sonja, she’s a fantastic Feeding Therapist!

    Sonja (and her lovely colleague, Sandra) were stupendous. I had brought my one-year-old son to see them as I was concerned that he wasn’t eating enough. They looked at his history and we ate together to make sure they had all the information they needed to give an accurate diagnosis. Whilst our outcome was that Henry was in fact doing brilliantly (and I just needed to chill out a bit!), I would imagine if there was something more serious going on, Sonja would make you feel just as supported and empowered as she did with us. Excellent follow-ups too. Money well spent for a bit of reassurance for a stressed out mama. Thank you, Sonja!

    Chaining: A powerful tool for phonological development

    Understanding chaining

    Chaining is a therapeutic technique I like to use in my speech therapy work with children who have Childhood Apraxia of Speech (CAS) or phonological speech sound difficulties. It helps to break down a complex target behaviour into smaller, more manageable steps. By systematically teaching and reinforcing each step, I can help my students achieve their communication goals.

    There are two types of chaining: Forward and backward chaining

    Today I am going to show and talk about backward chaining. This technique involves starting with the last step and working backward to the first. This approach can be particularly effective for children with persistent speech sound difficulties where combining consonants into clusters, such as /BL/ or /FR/ or /SHR/ is very difficult.

    Backward chaining allows my student to experience immediate success and build his confidence.

    In my video I show you how I applied backward chaining to the words ‘Shriek’, ‘Shrub’, ‘Shrimp’ etc

    My student struggles with both the /SH/ and the /R/ sounds and we have been working on both sounds for some weeks now. He has mild Childhood Apraxia of Speech and he has difficulties with coordinating his tongue movements, breathing and using his jaw effectively to make words. His sound repertoire has grown a lot since we started working together last year. Today in this session I show you how we pulled both the sound /SH/ together with /REEK/ to make ‘SHRIEK’. I love using the pictures and therapy materials from Adventures in Speech Pathology.

    This is also part of the Complexity approach which I will explain in a separate blog post.

    • Step 1 (not shown in the video): I explain what the word means; I find that when my student understands what a word means he is much better at saying it. It increases his confidence and motivation to say a word that he knows the meaning of. Often this student does not tell me that he does not know what a word means, so I always remind myself to check that out first.
    • Step 2 (not shown in the video): We do a little rhyming game and think about what any one word rhymes with: ‘Shriek’ – ‘meek’, ‘weak’, ‘seek’.
    • Step 3: I show my student that there are two parts to this word /reek/ and the sound /SH/.
    • Step 3: We practise the easier part: /reek/ /reek/ /reek/.
    • Step 4: We add the /SH/ sound and pull it together to make our target word ‘Shriek’.

    /REEK/ /REEK/ /REEK/ + /SH/ = ‘SHRIEK’
    /RUB/ /RUB/ /RUB/ + /SH/ = ‘SHRUB’
    /RUG/ /RUG/ /RUG/ + /SH/ = ‘SHRUG’

    By breaking down the word into smaller, manageable steps, my student can focus on each syllable individually, get that right and then gradually build up to the full word. This approach can help to reduce frustration and increase motivation.

    Forward chaining

    Forward chaining is the same process but in reverse: we start with the front sound or syllable and work forward towards the next/last part of the word:

    /SH/ + /REEK/ = ‘SHRIEK’
    /SH/ + /RUB/ = ‘SHRUB’
    /SH/ + /RUG/ = ‘SHRUG’

    Benefits of chaining

    • Increased motivation: By starting with the last step, my student experiences success, which boosts his motivation to continue trying to say the word and trying other words.
    • Reduced frustration: Breaking down the target behaviour into smaller steps can make the task less overwhelming, reducing frustration and anxiety.
    • Improved confidence: As the little learner masters each of the step, his confidence and self-esteem increases. Again, this leads to increased motivation.
    • Faster learning: By focusing on the final step first, and practising lots of chaining (forward and backward), a student can quickly learn to generalise to other words.

    Backward chaining (and forward chaining) is a really great tool for teaching complex speech sounds and words to children with phonological disorders.

    Watch out for my next blog which is all about the complexity approach in Phonology.

    Do get in touch if your child has a speech sound disorder, I would love to help.
