Speech prompts and strategies I use in Speech Sound Therapy

ByLondon Speech and Feeding May 14, 2024May 13, 2024

This particular student has a mild motor planning difficulty and six weeks ago he came to me with a very strong lisp. In addition to the lisp he is struggling to produce a number of sounds, SH and L on its own and all the clusters (FL/BL/KL/PL) but also CH together with some vowel difficulties.

The prompts are a mix partially from the DTTC (Dynamic Temporal and Tactile Cueing) model by Dr Edythe Strand as well as phonological models I have learned over the years, and some of them are my own.

Visual/picture prompts and Images

Here I use the ‘Flat Tyre’ Sound, to offer as an image for a new S sound and the ‘Tick Tock’ Sound for a new image of the T sound. Both cards are from the Bjorem Speech Sound Deck, which I love and use almost daily.

Gestural Cues

I like to use all the ‘cued articulation’ hand cues by Jane Passy for consonants and fricatives. Here we use our fingers and hand to illustrate what our tongue does, and we also show whether a sound is voiced or voiceless. When I use one finger it is voiceless (k/f/s/p) and when I use two fingers for the same cue it means that the voice needs to be turned on: (g/v/z/b/n/m). For vowels I like to use Pam Marshalla’s cue system.

Simultaneous production

We say the word together.

Direct imitation

I say the word and my student copies me directly.

Imitation after a delay

I say the word and then after a little wait my student says the word.

Spontaneous production

My student has now learned to say the word by him/herself.

Offering feedback

It sounds like… I just heard… I didn’t hear the first sound there? Can you try again?

Letting the student reflect

By just shaking my head or by looking quizzical so that my student realises something didn’t quite go right.

Postitive reinforcement

‘Yes that was it, do it again, nice one…’

Cognitive reframing

This is a technique where we identify different semantic cues and metaphors or imagery cues, so instead of teaching or focusing on a sound we try out viewing each syllable from a different point of view.

For example: ‘yellow’. I have had great success with this one: we start with just saying ‘yeah yeah yeah’. I might make a little joke and say something like ‘imagine your mum says tidy your bedroom, what do you say or what do you think?’ Answer: ‘yeah yeah yeah’. Then we practice ‘low’ together, I might blow some bubbles high and low and we talk about ‘low’. And then we put ‘Yeah’ and ‘Low’ together and now we have YELLOW!! It might at first still sound a bit odd, like ‘yea-low’ but we soon shape that up and have the real word.

Each student is different and having a great rapport is crucial to our success.

Then a little game break after some 7–10 or so repetitions and always trying to finish on a positive note.

What game breaks do I use:

Very quick ones! Students can post something, place a counter in a game, take out a Jenga block from the tower, pop in a counter for ‘connect 4’, stick a sword into the Pop the Pirate barrel or add a couple of Lego blocks to something they are building.

I hope this is helpful, please contact me for any questions.

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.

The art of selective care: My journey as a semi-retired private therapist
ByLondon Speech and Feeding September 3, 2025November 6, 2025

Welcome!

Hello, and welcome. I’m writing this today to share a bit about my professional journey, a journey that has evolved over many years from a bustling, full-schedule practice to a more intentional, deeply fulfilling semi-retired life. This shift wasn’t born out of a desire to slow down, but rather an understanding of what truly matters: my time, your time, and the quality of the work we do together.

For decades, I poured my energy into a full calendar, helping as many families as I possibly could. It was a wonderful, demanding, and rewarding time. I learned so much, grew immensely as a professional, and had the privilege of witnessing countless moments of breakthrough and success. But over recent months, I began to realise that the most impactful work wasn’t about quantity; it was about quality. It was about giving my whole, undivided attention to a select few, creating an environment where true progress could flourish.

Change

This realisation led to a significant change in my practice. I am now at a point in my career where my time is both valuable and precious. It is no longer a commodity to be filled, but a resource to be invested wisely. This doesn’t just apply to my personal life, but to my professional life as well. I’ve chosen to be more selective about the clients I see, and this selectivity is rooted in a single, powerful question: ‘Who can I truly, profoundly help?’

I believe that successful therapy is a partnership. It requires commitment, trust, and a genuine connection between therapist and client. When I take on a new family, I am not just filling a slot in my schedule; I am making a deep commitment to them. I am dedicating a part of my precious time and decades of expertise to their child’s success. This is why I am now focusing on who I can really work with: families who are equally invested in the process, who understand that progress is a team effort, and who are ready to engage fully in the journey.

My fees reflect this deep investment. You will find that my rates are higher than those of many other therapists, and I want to be transparent about why. It’s a reflection of the extensive experience I bring to the table. I have spent years honing my skills, navigating complex cases, and developing a unique, effective approach to speech, language and feeding challenges. This is not just a job for me. It is my life’s work, and I honour the value of that expertise and the time I dedicate to each family.

I want to ensure that every minute you spend with me is productive, focused, and truly transformative. Therefore, I provide a ‘boutique style’ of care. Think of it as an exclusive, personalised experience where every detail is considered and your needs are at the forefront. You won’t feel like you’re just another appointment on a long list. You will feel that you have my full, undivided attention, as if you were my only client.

This means less time spent on administrative tasks and more time dedicated to preparing for your sessions, reflecting on our progress, and providing you with the most thoughtful, tailored support possible. It means an environment of calm and focused expertise, where we can truly dive deep into the specific challenges and build a clear, effective path forward.

New perspective

For parents reading this, I hope this provides a new perspective. Choosing a therapist for your child is one of the most important decisions you can make. It’s about finding not just a professional, but a partner. I want you to feel that, if we choose to work together, you are entering into a unique partnership where your child’s growth is my singular focus.

In this next chapter of my career, I am prioritising passion over pace, depth over breadth, and meaningful connections over a packed schedule. I am here to work with families who are ready for a truly collaborative and transformative experience. If you are seeking a level of care that goes beyond the standard, an approach that is both highly experienced and deeply personal, I would be honoured to speak with you.

Navigating the exciting 9–18 months journey: Your baby’s communication milestones
ByLondon Speech and Feeding February 3, 2025January 31, 2025
Between 9 and 18 months, your little one undergoes a remarkable transformation, blossoming from a curious explorer into a budding communicator. This period is filled with exciting milestones in speech, language, and social development. Let’s delve into what you can expect.

9–12 months: The world opens up

Communication takes flight
- Babbling becomes more complex with a wider range of sounds. By babbling we mean syllables like: pa ga ka ma da and then ‘baba’ gohgoh’. First we hear one and two syllables together and then longer and longer strings! This is so exciting!
- First words! One day around the 12 months–14 months mark we hear a first word! My older son’s first word was ‘Licht’ which is the German word for ‘light’ as literally every time I carried him along the corridors in our home, I pointed out the light switches to him and turned them off and on a few times. And each time I said ‘Licht!’ and it stuck! PS: sadly I cannot remember what my younger son’s first word was… poor second and third babies they just have to muddle along and call loudly to get noticed!
- Understanding grows! Baby now understands simple instructions like ‘where is your ball’ and responds by looking to the ball across the room!
Social butterflies
- Your baby now starts to show interest in other children, and may try to copy their actions. Now we are getting proper traction with simple social games like peek-a-boo and patty-cake. Whilst your baby is generally interested in other people and children he or she may show separation anxiety when mum or dad or other familiar person suddenly leaves the room and they feel alone with strangers.
Fine motor skills
- Pincer grasp develops. This is where your child puts an index finger to the thumb in order to pick up of small objects, hold them and transfer them to either a box, back on the floor or into the other hand.
- Your baby may start to explore objects by banging, shaking, and mouthing.
12–15 months: Words are taking shape
- Language explosion: From our early words we now suddenly see baby’s vocabulary expanding, with new words added each week. I would highly recommend parents keep a little journal of all the words they hear. If nothing else this is a wonderful aide-memoire for years down the road when you might like to reminisce about the first ten words. I promise you otherwise you won’t recall! (especially for second and third babies; I would do this now, had I the time again).
- Understanding grows:
  
  By about 15 months our baby can follow simple two-step instructions like ‘Go get your shoes and bring them here.’
  
  Begins to understand the concept of ‘no.’ and that’s a very useful thing. Though before you breathe a sigh of relief… your toddler may well show you that he is understanding a ‘no’ though he may not stop doing what he is doing or come down off the table!
- Playtime gets interactive:
  
  Now we engage in more complex play, such as stacking blocks, pretending to eat with a spoon, and imitating actions.
  
  Many toddlers now start showing an interest in picture books.
15–18 months: Communication blossoms
- Words combine: Towards 18 months or around about then your toddler may start to put two words together, such as ‘more milk’ or ‘bye-bye dada.’
- Gestures and sounds: Now we also use gestures to communicate, such as pointing, shaking head ‘no,’ and waving ‘bye-bye.’
- Exploration and curiosity:
  
  Your toddler is now EVERYWHERE! Turn your back and he or she is gone! Your toddler now shows a strong sense of curiosity and explores their environment with enthusiasm.
- Copying
- Look out for actions and gestures your toddler will copy such as clapping hands or patting a cushion or banging a spoon on the table .
Remember
- Every child develops at his or her own pace.
- These are just general guidelines, and some children may reach certain milestones earlier or later than others.
- If you have any concerns about your child’s development, please consult with your speech and language therapist. We are always keen to hear from parents and happy to help promote all those lovely early skills.
General tips to encourage communication if you feel your child needs a little more help
- Talk, talk, talk! Engage in frequent chatting with your child.
- Listen to your child: Allow for periods of silence when playing with your child to allow them to say something or make sounds which you can then copy and respond to.
- Read aloud regularly. Use books with simple words and pictures.
- Play interactive games: Hickory Dickory Dock, Row Row the boat, Old McDonalds, 5 little monkeys jumping on the bed, chasing and catching, tickling games.
- Respond to your child’s babbling and gestures. You can copy them or if your toddler says long strings of babbling you cannot understand you could just say: ‘Oh ok!? ‘yes that’s great!’ ‘who knew!’ ‘wow you’ve got much to say!’ as if you understood.
- Limit screen time or if your child is very passionate about watching clips then sit and watch with your child so that you can see what is the best bit, which songs they like the best and what sort of phrases they love hearing.
This exciting period of rapid growth and development is a precious time for both you and your child.

By providing a loving, stimulating, and responsive environment, you will naturally nurture their communication skills! Any more questions, please get in touch!

One activity, endless opportunities for speech and language therapy targets
ByLondon Speech and Feeding May 19, 2026May 18, 2026
Communication does not happen in neat little boxes. In Speech and Language Therapy we often use one great activity to target multiple areas of speech and or language development all at once.

Children are trying to:
- understand language
- build sentences
- organise their thoughts
- pronounce sounds
- remember words
- use grammar
- follow social interaction
- communicate meaning…
all at the same time.

This short therapy clip is a little example of that.

Within one playful interaction, we naturally work on:
- grammar
- sentence expansion
- pronouns
- speech sound errors
- modelling
- visual cueing
- turn-taking
- confidence in communication
And, importantly, the child remains engaged, relaxed, and successful throughout.

Using language activities to refine speech sound targets

We all learn language through:
- shared attention
- play
- repetition
- connection
- modelling
- responsive interaction
As a Speech and Language Therapist I am constantly thinking and considering how to bring in all the targets a child is working on. The reason for that is that often we do not have a full therapy hour to work leisurely and calmly on various targets! Many children have short attention focus and ‘go off the boil’ quickly and often suddenly. Therefore, I always feel a sense of ‘make hay whilst the sun shines’ and pack it all in whilst the going is good. So then we can afford five minutes of trampolining in between activities to help the child regulate themselves without losing valuable speech therapy opportunities or time.
- How can I expand this sentence?
- How can I model better grammar?
- Can I gently shape the pronunciation here?
- Should I recast that phrase?
- Is this the right moment to pause and encourage a longer utterance?
- How can I keep communication flowing while still targeting goals?
These decisions happen continuously during therapy.

Building longer sentences naturally

In this clip, one of the key areas we are targeting is sentence expansion through Colourful Semantics, which is a particularly useful and researched approach, developed by UK Speech and Language Therapist Alison Bryan in 1997 to support children with speech and language difficulties.

Colourful Semantics is a visual, colour-coded therapy approach that helps children break down, understand, and construct sentences by assigning specific colours to thematic roles (e.g., Who, What Doing, What).

Many children with language delay use reduced language for example: they might say:
- ‘dog’ instead of ‘the dog is running fast’
- ‘eatin a dinner’ instead of we are eating our dinner
- ‘baby shhh’ instead of ‘the baby is sleeping’.
Using the Colourful Semantics Framework helps create a solid baseline from which to work and with which to construct basic good sentences using WHO is DOING WHAT and WHERE.

We are building language upward gently and positively.

This technique is incredibly powerful because children learn language through hearing it used meaningfully over and over again.

Supporting pronouns through real conversation

Pronouns can be surprisingly difficult for many children.

Words such as:
- he
- she
- him
- her
- they
require children to understand perspective, grammar, and sentence structure all at once. Using pictures and basing the activity on the Colourful Semantics Model I can shape pronouns repeatedly as part of the overall activity.

Books, pictures, and play scenes are fantastic for this because they create endless opportunities for meaningful repetition.

Again, this may look simple from the outside.

But underneath it is highly intentional clinical work.

Listening for speech sound errors at the same time

While supporting grammar and language, I am also constantly listening to the child’s speech production.

In this short interaction, I respond to speech sound errors as they arise.

Sometimes I:
- model the correct production
- emphasise a sound slightly
- use visual cues
- slow the word down
- add gesture or sign support
- encourage another attempt.
And sometimes I intentionally let the error go in order to protect confidence and maintain communication flow.

That balance is incredibly important.

Children need support. But they also need to feel successful communicating.

The child simply experiences this as warm, responsive interaction.

But underneath it is detailed clinical reasoning.

This is why effective therapy is never about simply owning resources or downloading activities online.

The real skill lies in:
- how the therapist uses the activity
- how they adapt moment by moment
- how they analyse communication in real time
- how they shape interaction to maximise learning opportunities.
One activity. Endless opportunities.

A single book, picture scene, or playful interaction can provide opportunities to support:
- speech sounds
- language development
- grammar
- vocabulary
- attention
- confidence
- social communication
- emotional connection.
The magic is not in the activity itself.

The magic is in how a therapist uses it.

Because excellent speech therapy is never ‘just playing’.

It is careful, responsive, evidence-based intervention woven seamlessly into joyful interaction.

Explore the relationship between poor speech, language and communication and literacy skills
ByLondon Speech and Feeding November 14, 2022January 31, 2023
Communication skills are critical in all areas of communication throughout childhood and into adulthood. They are needed for understanding, narrating, making predictions and to develop social skills, for example in understanding everyday language or talking in the classroom or socialising with peers. Children with communication needs can experience low self-esteem, potential behavioural difficulties, lower school attendance and attainment.

Communication skills have a strong impact on literacy. Let’s look at some of the facts:
- 50% of children with language delays also have challenges with literacy (Burns et al, 1999).
- 73% of poor readers in year three had a history of difficulties with phonemic awareness (the ability to hear, identify and manipulate sounds) or spoken language in pre-school (Catts et al, 1999).
The effect of expressive language on spelling and reading

The ability to read is very much dependent on competent language skills. Furthermore, a limited vocabulary will also have an impact on literacy skills. The more we know about a word, the easier it is to retrieve, recall, understand and use. So, if a young person has a poorer vocabulary, it’s likely that they will not have the same decoding skills as a peer with a richer set of vocabulary. By decoding we mean the ability to apply knowledge of letter-sound relationships including pronunciation of words. Decoding is a vital skill used in literacy.

Whilst learning to read is a key skill, it’s important to remember that a solid foundation is needed for success. We need to ensure that no steps are missed, otherwise there will be gaps in knowledge.

As your child moves further through the education system, they will be “reading to learn”. This is where young people with poorer language skills may show literacy difficulties (for example, reading comprehensions become more challenging, and their expressive language skills impact on their written abilities).

When should I seek advice or support?

Always seek the advice from a qualified professional such as a Speech and Language Therapist. You need appropriate advice for the age and stage of your child’s development and early intervention is of course key to success. It is never too late to ask for advice. The earlier you seek support, the better the outcome for your child in all areas (language, literacy, and emotional well-being).

Have you still got unanswered questions? Contact me here and we can have a look at your child’s phonemic awareness, auditory processing skills, verbal understanding and assess his/her ability and likelihood of reading and literacy struggles. If we find that your child has dyslexia I can refer on to a specialist colleague who can help you further.

Conquering the ‘slushy’ /S/: Your guide to treating lateral lisps
ByLondon Speech and Feeding August 13, 2025November 27, 2025
As a speech therapist, few things are as rewarding as helping a child find their clear, confident voice. Among the various speech sound disorders, the ‘lateral lisp’ – often described as a ‘slushy’ or ‘wet’ /S/ sound – presents a unique challenge. While it can be tricky to treat, I’m thrilled to share that I’ve had significant success in helping children overcome this particular hurdle.

What is a lateral lisp?

Most people are familiar with a frontal lisp, where the tongue protrudes between the front teeth, resulting in a /TH/ sound for an /S/ (e.g., ‘thun’ for ‘sun’). A lateral lisp, however, is different. Instead of the air escaping over the front of the tongue, it escapes over the sides, often giving the /S/ and /Z/ sounds a distinct, muffled, or ‘slushy’ quality. This happens because the tongue is not forming the correct central groove, allowing air to spill out laterally.

The science behind a perfect /S/ vs. a slushy one

To understand how to fix a lateral lisp, it’s helpful to understand how a ‘perfect’ /S/ sound is made. Imagine a narrow, focused stream of air. For a clear /S/ sound, your tongue forms a shallow groove down its centre, directing a precise, thin stream of air right down the middle, over the tip of your tongue, and out through a tiny opening between your tongue and the roof of your mouth, just behind your front teeth. This focused airflow creates that crisp, sharp /SSSS/ sound we recognise.

Now, picture what happens with a lateral lisp. Instead of that neat, central channel, the tongue is often flatter or positioned in a way that allows the air to escape over one or both sides. Think of it like a river overflowing its banks – the air, instead of flowing in a controlled stream, spills out sideways, creating that characteristic ‘slushy’ sound. This lateral airflow is what we need to retrain.

Why is it tricky to treat?

Treating a lateral lisp can be challenging for a few reasons:
- Habitual muscle memory: The way the tongue moves and positions itself for a lateral lisp is deeply ingrained. It’s a motor habit that needs to be unlearned and replaced with a new, more precise movement.
- Subtle differences: The difference between a lateral lisp and a correct /S/ sound can be quite subtle to perceive, both for the child and sometimes even for parents. This makes it harder for the child to self-monitor and correct.
- Oral motor control: It requires fine motor control of the tongue muscles to create and maintain that central groove for airflow.
My success with children aged six years and over

I’ve found great success in treating lateral lisps, particularly with children aged six years and older. Why this age group? By this age, children typically have:
- Increased awareness: They are more aware of their speech and often more motivated to make changes. They can better perceive the difference between their ‘slushy’ /S/ and a clear one.
- Improved cognitive skills: They can understand and follow more complex instructions and strategies.
- Better self-monitoring: Their ability to listen to themselves and correct their own speech improves significantly.
- Enhanced oral motor control: Their fine motor skills, including those of the tongue, are more developed, allowing for greater precision.
My approach focuses on a combination of auditory discrimination, tactile cues, and targeted myofunctional exercises to help children ‘feel’ the correct airflow and tongue placement. We use a variety of engaging activities to make the process fun and effective.

It is crucial to understand tongue functioning and focusing on correcting improper oral resting posture and muscle function, which are often significant contributors to a lateral lisp. For example, if the tongue rests low and wide in the mouth consistently, or if there’s a tongue thrust during swallowing, these habits can prevent the tongue from achieving the precise, midline placement necessary for a clear /S/ or /Z/ sound. Through targeted exercises I aim to re-educate the oral and facial muscles, promoting correct tongue posture at rest, during swallowing, and, ultimately, during speech production. By strengthening the muscles responsible for tongue lifting and encouraging a more appropriate swallowing pattern we can establish the correct oral motor skills needed to overcome a lateral lisp and achieve clearer articulation.

The recipe for success: Little and often

The single most crucial ingredient for success in treating a lateral lisp is daily home practice of all the strategies given. This isn’t about long, arduous sessions; it’s about consistency. Think of it like building a muscle: short, frequent workouts yield better results than sporadic, intense ones.

My recommended formula is ‘little and often’. This means:
- Short, focused sessions: Aim for 5-10 minutes of practice, 2-3 times a day. This prevents fatigue and keeps the child engaged.
- Integrate into daily routines: Practise while waiting for dinner, during a car ride, or before bedtime. Make it a natural part of their day.
- Positive reinforcement: Celebrate every small success! Encouragement goes a long way in building confidence and motivation.
- Parental involvement: Parents play a vital role in providing consistent cues and encouragement at home. I equip families with clear, easy-to-follow strategies.
Overcoming a lateral lisp requires dedication, but with the right guidance and consistent practice, a clear, confident /S/ sound is achievable. If your child is struggling with a ‘slushy’ /S/, please don’t hesitate to reach out. Together, we can achieve success!
