When a child with autism, Asperger’s or PDD-NOS is diagnosed it is often quite obvious to families to see why Speech Therapy is an important part of intervention. However it is not often clear how Occupational Therapy can be utilised to improve their child’s “Sensory Processing” which has a huge impact on their  social and communication development.

As you may or may not know “Sensory Processing is the organisation of sensation for use” (Ayres). What this means is that our brains are constantly taking in sensory information from our surroundings and trying to make sense of it. We then process this information to be able to behave and learn in an effective manner.

Many children with autism can be challenged in this area of development which makes the world a very confusing and sometimes crazy place to exist! Much of their energy is spent trying to interpret the sensations that they are receiving and they are often not able to focus on the things that we think are important. When this flow of sensations in the brain is disorganised, life can be like a rush hour traffic jam, so no wonder it becomes hard for children with autism to concentrate!!

Poor Sensory Processing is one of the major reasons why children with autism can have so much difficulty with ‘attention’ (among other things).

If your child has problems with Sensory Processing you may notice that your child…

1. Spends too much time attending to certain parts of toys/objects

2. Is drawn to certain games/activities that have a visual, auditory, touch or other sensory focus

3. Has difficulty focussing when in noisy or busy environments

4. Doesn’t play with toys in a conventional way but chooses to find a sensory way of playing with it

5. Becomes easily overexcited in activities

6. Switches very quickly from being calm to very agitated/upset

7. Has the need to constantly move

8. Changes quickly from one activity to the next etc, etc

In order for your child to be able to socialise, communicate and learn effectively from others it is vital that they are able to attend and focus in a calm, organised and alert state. If they are having trouble with this then they are going to find it very hard to learn effectively through ‘joint attention’ with other people, which is necessary for the development of social and communication skills.

Occupational therapists, that specialise in ASD, can certainly assist you with improving your child’s attention and focus by carrying out Sensory Integration Therapy. Please never underestimate the importance of ‘sensory integration’ work because getting your child into their optimum state is the foundations of all learning.

If you do not have access to an Occupational Therapist who specialises in sensory integration and/or you would like to learn more about this necessary area of development (as many professionals do not have time for training parents during their sessions) …please take a look at my training modules ‘Sense Part 1 and 2’.

I would also love to hear your stories of how improving your child’s sensory processing skills has had a greater impact on your child’s learning as well as social and communication development.

3. Is Your Child’s Therapy Team Really Working Together?

Parents often ask me the question…

“Would a mainstream preschool or school be suitable for my child?”

To be honest with you there is an incredible amount to consider when answering this question and of course all children with autism are very different. So I’d like to give you some advice to help when you are making this decision…

 

1. Your child’s happiness is of utmost importance! So if being in a mainstream school allows your child to be calm and happy and be supported in a safe and nurturing environment, then this is wonderful! A lot of children with autism experience high levels of anxiety so this is very important to consider when finding the right setting for your child to thrive in. If your child is unhappy and on edge then they will most likely be in ‘survival mode’ for most of the day and will not get anything out of their day… just unhappiness.
2. Will your child ‘thrive’ in a mainstream environment? Is the teaching pitched at the right level for your child? The last thing you want is for your child to be getting very little out of their day and slowing down the rate of their development. If the teaching is pitched at a level that is too difficult for your child then you might find that they are only learning 1-2% of their day… and that’s a pretty scary thought!
3. Children with ASD often find it very difficult to shift their attention from what they are doing to what a teacher or a peer would like them to be involved in. This is very much related to their challenges with joint attention. If this is the case for your child then possibly a more structured and specialised environment that incorporates the use of visuals and other specific teaching strategies could be far more effective your child.
4. It is important to remember that cognitive and academic skill advancements should NOT be the only focus of your child’s schooling. School/preschool is also a valuable environment for the development of ‘meaningful’ peer relationships and improving skills that will help your child function more ‘effectively’ and practically in their day to day environment. Please consider which type of schooling will help support this, because at the end of the day social and emotional intelligence is what will help your child live a happy and fulfilled life.
5. Finding a setting where the staff understand autism and the importance of getting to know the ‘individual differences’ of your child is critical. In saying this I have also consulted to mainstream settings where the staff know very little about ASD but they have a real willingness to learn and are incredibly motivated to help the child as best as they can. This passion counts for a lot! Each preschool and school are very different so it is critical that you do your homework and shop around.
6. Many people underestimate what a child needs to be able to ‘comprehend’ to keep up in the classroom. The conversations and topics that are discussed can be quite complex and abstract. I went to see one of my 5 year old clients at school a few months ago and the children were expected to be able to look around the playground and tell the teacher what was ‘man made/artificial’ and what was ‘natural’. This kind of activity is extremely challenging for a child with autism who has difficulty understanding and interpreting the world around them!

So… I’ve started this discussion off… but I’d love to hear your own thoughts on things that are important for parents to consider when determining the ‘just right’ school setting for their child. There are so many more ideas we could share….

3. Don’t forget about toy libraries!

Howdy all,

Well I am now the proud mother of two beautiful children. Our little boy Liam was born on the 30th of March and he has certainly been a lovely addition to our family. Though I can hardly say ‘little’ as he weighed in at 4.45 kg, which is nearly 10 pounds! Eek…poor me

Anyway we are enjoying him immensely as there is nothing quite like a cuddle form a newborn baby.

In my last blog post we looked at some of the main things to think about and some key questions that you should ask any speech pathologist before employing their services to help your child with autism.

After you’ve been working with your therapist for a few months you’ll want to know if the therapy is actually making a difference and that you child is making some real progress. This depends greatly on how good a ‘match’ your therapist (and the therapy) is for your child.

So today (as promised) I’d like to share with you some of the warning signs that may indicate that it’s time to find another speech pathologist who is ‘a better match’ for your child.

If you haven’t read my previous post about why this is so important please read it now.

As you know, time is precious and no parent wants to waste it when treating their child with autism! This is particularly true for early intervention. So it’s very important that you are able to determine as early as possible whether the therapy your child is receiving is effective or not… otherwise days will turn into weeks that will turn into years…and before you know it time is slipping away.

But fear not

Here are some tips to help you determine just how effective your child’s speech therapy really is… and whether you should continue with your current therapist or start looking for another one…

1. Does your child have a good connection/relationship with their speech pathologist?

Please remember that without a warm, trusting and fun relationship your child will not genuinely want to interact or learn from their therapist. This is essential for creating a solid foundation for all future learning.

2. Is your child enjoying their therapy sessions?

Two of the primary ingredients for learning new things and laying down memories are ‘fun’ and ‘motivation’. So for speech therapy to be effective is must be fun and motivating for your child. It’s crucial that your therapist incorporates your child’s interests into their therapy sessions. If your child is attentive in the activity because it ‘pushes their buttons’ then the quality and rate of learning will be far greater. So if after several months of therapy, if your therapist is not incorporating highly motivating activities into your sessions (easy to spot because your child will be bored and disinterested 8 out of 10 sessions)… or worse still, they may not even be aware of what activities actually motivate your child, then it may be time to move on.

3. Are there noticeable improvements in your child’s Social and Communication Skills as a result of the goals that are being targeted in speech therapy?

Can you notice a difference in day-to-day functioning of your child? Can others notice a difference?

The reason that I ask you this is because sometimes speech therapy sessions can seem to be going well ‘in the clinic’ but these improvements do not necessarily translate to the everyday functioning of your child…. and let’s face it, this is what is really important!

This can happen if the goals that are being set are not very meaningful and important to the child’s existence. In my opinion, the best way of speech therapists creating practical and meaningful goals is by doing home and school visits that clearly show the therapist what is important to target in intervention. If a speech therapist is simply creating goals as a result of carrying out some formal language tests then there is a good chance that the goals will not be practical and meaningful and perhaps will not target the social aspect of communication development. Instead they will just end up teaching splinter skills (i.e: following instructions, answering questions, requesting things etc) without addressing their application in day to day life.

4. Are you clear at the end of each therapy session what goals you are targeting in therapy and what you need to work on and practice before the next session?

I know you already know this but an hour or so of speech therapy weekly or fortnightly is simply not going to create the huge breakthroughs you want for your child. Whenever possible you need to be following up and working with your child at home. It only needs to be for half an hour or so but it must be regular.

Therefore it is crucial that your speech therapist is including a lot of parent training and education in your sessions so that you feel confident on how to apply what you’re working on at home (another really good reason why your therapist needs to understand what goes on at home so they can give you practical activities and exercises that actually work in the home environment). By doing this you will gradually learn how to make every interaction with your child a fabulous learning opportunity… which is when you start to see the big breakthroughs!! So if your therapist is not helping you achieve this then I’d suggest that you’re not getting the most out of them!

5. Lastly. Trust your own intuition as a parent!

Some families will say to me “I knew for a long time that the therapy was not right for my child and I felt like I was just handing over my money at the end of the session and not achieving very much”. If it doesn’t feel right to you then it’s probably not! But make sure you give something new a few months before you decide to stop.

A final thought…

Please do not waste your precious time and resources on therapy that you feel is ineffective or not a ‘good match’ for your child. Constantly review and challenge the effectiveness of your therapist’s intervention and make the necessary changes by trusting your intuition. I can’t tell you what a buzz it gives me to see parents who feel so capable and confident to trust their intuition because they have spent a little bit of time every day training and empowering themselves to better understand their child’s needs.

Please keep these things in mind at your next session!

If you would like further assistance in building your knowledge and practical skills to help your child on a daily basis and to become better at assessing the effectiveness of their therapy sessions then I think you’re really going to get a lot out of my Autism Essentials In-home Training Program.

As always, I’d love to hear about your experiences and stories that you may have on this issue.

1. What you should know before choosing a speech pathologist for your child with autism
2. Effective Speech Therapy… what works and what doesn’t
3. Is Your Child’s Therapy Team Really Working Together?

I’m now past my due date for our baby boy to arrive and since I’m just sitting around waiting for him to come I thought I’d quickly take a few minutes and share some more thoughts with you…

It’s very important when finding a speech pathologist for your child that you get the ‘just right fit’.

Here’s why it’s so important…

Just as there are many areas of specialty for doctors (orthopedics, pediatrics, geriatrics, cardiologists, neorologists, etc) the same applies for speech pathologists. Areas of specialty can include stuttering, articulation, literacy, hearing impairment, language disorders, voice disorders, strokes, laryngectomies etc, etc… the list is very extensive!

But the thing that completely baffles me is that some speech pathologists say that they have 5-8 or more “Areas of Specialty”! To me this suggests that they do not specialise at all, and are more of a ‘generalist’ speech pathologist (like a GP is a generalist doctor). Some therapists even say that they ’specialise’ in autism when they may have treated only 10-20 children on the autism spectrum.

In my view, you’re only a ’specialist’ if you work exclusively on just one thing and only one thing… and as a result, you tend to become quite good at it
Heck! I’ve been specialising in autism for over 12 years and I’m still learning things with every new client I treat.

As we know, children with autism are ALL incredibly different and unless your child is seeing a speech pathologist who’s caseload is predominantly children with autism, there’s a good chance that the therapist would not have had the time or experience to truly equip themselves with the knowledge and skills needed to really help your child with autism.

If I had a child with autism…
Here’s a list of key questions I would ask any speech pathologist before employing their services:

1. How many children with autism have they treated before?
   Anything below 50 is really quite a small number. If they are just starting out that’s ok, we all have to start somewhere, but I would fully expect them to be mentored by a senior therapist with well over 50 clients under their belt.
2. What percentage of the children that they treat are on the autism spectrum?
   This will give some indication of the therapist’s level of commitment to treating children with autism and may also indicate the amount of professional development that the therapist has done in the field of autism.
3. Have they treated children on the autism spectrum with your child’s specific diagnosis (eg: Mild autism, severe autism, PDD-NOS, Aspergers)? How many?
   Some therapists may not have had experience working with the full spectrum of autism.
4. What age range do they mainly treat?
   Some therapists may only specialise in either early intervention or school aged children.
5. Is there a possibility of having home or school visits?
   I firmly believe that it is essential to get into the homes and schools (the main social and communication environments) of children with autism so that you can get a ‘true picture’ of what is going on for the child and family. Sometimes home and school visits are not always logistically possible for every session but I would certainly favour a therapist who was willing to do them now and again.
6. What style of Speech Pathologist are they? Is the therapy play based or structured learning at the table, is it adult directed or child directed?
   I very much believe in a play-based, child-directed and practical therapy approach where building a relationship with the child that is based on fun, trust and respect is pivotal to successful treatment. If a solid, trusting relationship is not present then your child will not build their desire to interact or learn from the therapist and the effectiveness of therapy will be compromised.

   A relationship builiding approach to speech pathology ensures that we are not only working on the ‘Communication’ element of the triad of impairment but also the social part. This is essential when treating speech and language skills and MUST NOT be ignored because social skills development drives communication development!!

   Some speech pathologists use a skills-based approach where they set the agenda for the child’s learning and carry out ’structured teaching’ sitting down at a table drilling them on certain concepts or commands. This type of learning can often be very unmotivating for the child and often does not tap into what learning is important and meaningful for the child.

Now obviously it would be an ideal world if every child with autism could be matched with the right speech pathologist (and you should absolutely keep striving for this), but the practical reality is often quite different. Specialist services can often be hard to come by and most of the time parents will settle for ANY help rather than none! And even when you manage to get ‘a good’ therapist, it takes time and a few sessions to determine whether they are ‘right’ for your child.

This is exactly why parents need to be able to step in and fill in the gaps and to recognise when things aren’t working as well as they could be and to make changes in their child’s program that will result in positive outcomes for the child.

How do you do this? By knowing your child better than anyone else (including their therapists). You need to understand what they need, what motivates them, how they learn best and what type of therapy approach is going to get the best results for them.

If this is kind of making sense for you and you’d like to have a greater understanding of all these things about your child so you can feel more empowered and confident to make these sorts of decisions for them then I’d really suggest that you check out my Autism Essentials In-home Training Program.

I hope you’ve found these tips helpful. Just make sure to keep them in mind when choosing a therapist for your child.

I’d be really interested to hear your thoughts and stories on this.

Howdy everyone,

I’m sorry that some of you have not heard from me for a little while. Things have been crazy busy!!!

Not only am I due to have our second child any day now but I have also been running some training workshops here in Sydney for other speech pathologists to share my knowledge and experience in working with children with autism.

I really enjoyed doing the workshops and the attendees got a lot out of them, which was great!

One of the main aims of running the workshops was to help shift the way that speech pathologists work with children on the autism spectrum. I figured that if I can help fellow speech pathologists work more effectively with these kids then I will indirectly be helping many more families because they will have greater access to speech pathologists who are trained with the unique knowledge and skills that are needed for treating children with autism.

The title of the workshop is “Effective Speech Pathology… what works and what doesn’t”. Some of the key messages that I shared were:

1. It IS possible to treat the social part of the triad of impairment
2. When we use a developmental approach to treatment we are treating the core deficits of autism
3. We must get to know the ‘individual differences’ of the child if we are to achieve greater therapy outcomes
4. Parent training and empowerment is an essential part of effective treatment
5. Practical and meaningful speech pathology is a must

I then went on to practically explain how I carry out ‘effective therapy’ with the families I treat, using lots of client examples and video footage etc.

In a nutshell….
As speech pathologists I strongly believe that we need to be carrying out a ‘relationship building’ and ‘developmental style’ of therapy rather than sitting these children down at a table, drilling them with specific, isolated skills that are often not meaningful or motivating for the child.

After specialising in the treatment of autism for over 12 years and consulting to many different programs, I’ve treated enough clients and seen the case history of enough families to know that this structured style of teaching does not address the core deficits of autism or lay the foundations for even more effective learning.

I am a very open-minded therapist and certainly not ’stuck in my ways‘ but I still continue to practice a relationship building style of therapy today for one very simply reason… because I find it get results.

My plan now (after our baby is born!), is to travel around the other capital cities of Australia to carry out the workshops there, then head overseas to do the same. Towards the end of the year I’ll be running more advanced training days for speech pathologists to increase their skills even further.

So along with continuing to manage Connect Therapy and creating more Training Resources I’m very excited to now be training other therapists in autism as I know that it will reach so many more families and quite possibly indirectly assist each one of you in your journey as well as other families that will follow in your footsteps!

So that’s what I’ve been up to… how about you guys?
How effective have you found Speech Therapy to be in your child’s treatment? What type of therapy approach has worked for you? I’d love to hear your experiences from a parent’s perspective.

Happy New Year!

My first blog entry for 2010. I hope it’s a great year for everyone.

This is Part 2 of how to help children with autism maximise their learning and connection using picture books. It’s a follow on from Part 1 which we did last week. If you missed Part 1 please watch it first, otherwise this may not make much sense to you.

You can watch Part 1 here http://www.autism-essentials.com/blog/maximising-learning-with-picture-books/

So as promised, in Part 2 I walk you through some real examples of exactly how I use picture books to connect powerfully with children with autism and explain the various techniques I use during the process that will really help to maximise their learning and connection throughout the activity.

There’s some really valuable tips in this, so I hope you enjoy it!

I really hope that you trial some of these techniques with your own child or those that you treat. Please let me know how you go.

P.S: As always If you have any thoughts or stories to share about this week’s article please leave your comments in the box provided below.

1. Maximising Learning and Connection with Picture Books – Part1
2. Maximise Your Child’s Learning With Visuals

Wow! Only 4 more sleeps until Christmas!

I thought I’d squeeze in one more autism tip to help get you through the holiday period.

This week’s video is about getting the most out of your interactions with your child with autism while reading picture books with them. And because this is an activity that almost all children and parents enjoy doing together quite frequently, I’m sure you’ll find this one very helpful.

Take a look…

Duration – about 10 min

Here a little peak inside this weeks video…

There are essentially 4 types of interactions a child with autism can have whilst reading a book.

Which one does your child experience the most?

1. They enjoy the physical, visual experience of turning the pages ad looking through the book and it’s usually an activity they prefer doing on their own.
2. They don’t mind if you sit with them, but they like to control the reading of the book and don’t really involve you in the experience.
3. They enjoy reading books because they like the process of rote learning, the sequence of events and knowing what is on the next page. They don’t mind if you get involved but they are really only using you as a tool to help them get from page to page and it is not a true shared experience.
4. Your child genuinely enjoys reading books with you and it is usually a highly interactive experience with lots of back and forth conversation and emotion sharing.

If you said number 1, 2 or 3 that’s fine. However number 4 is the type of interaction we want to aim for. This is where your child is going to get the most out of the experience and will get the most opportunities to maximise their learning and their ability to really ‘connect’ with you and eventually other people too!

So I’ve really tried to focus this video on giving you some simple steps that should really help improve the quality of your interactions with your child whilst reading together. So what are you waiting for. Go back up and click play now!

Stay tuned for Part 2 – which I’ll be releasing next week.
Until then, stay safe and have a really great holiday break.

Part 2 is now available here – Watch Part 2

All the best

2. If you want more language you need to expand your child’s world

Often toy libraries can be a very underutilised service in many communities… but they have a lot to offer, particularly for children with autism, aspergers or pdd-nos.

Many families say “We have so many toys at home…the last thing we need is more toys”

But let me give you a little bit of food for thought….

I saw a boy named Oli on the weekend for a session who will be going to a mainstream school next year.

He is doing really well with his play and interactions at home with his parents and his brother. This family have done an incredible job at building their relationship with Oli, helping him realise that they are heaps of fun to be around and can add so much value to his life. In fact, when I recently analysed some video footage of Oli playing with his family at home it really was not apparent that he had autism!

Yet aside from all of his wonderful progress at home his parents report that he is having significant trouble forming relationships with his peers.

One of Oli’s challenges is that he experiences a considerable amount of anxiety which is getting in the way of helping him develop friends. The thing that triggers this anxiety for Oli is new and unpredictable things. For example when he has play dates with friends, away from home, there is soooo much unpredictability (new home, less familiar people and of course new toys!).

So we needed to focus on helping Oli become more comfortable with new situations. Therefore I recommended that this family create more unpredictability in their play time at home, where Oli already felt very safe and secure.

One excellent way to create this unpredictability is by introducing different toys into your child’s play sequences.

But as you no doubt know, kids can get bored of the same toys very quickly. So if you’re child is no longer motivated by the toys you have at home, an excellent source of new and interesting toys can be your local community toy library… just like a plain old book library but instead you can borrow toys! Plus what’s also great is that as soon as your child gets bored of them you can simply return them!

Just do a Google search for toy libraries in your local area. Obviously some toy libraries are better equipped than others but it’s definitely worth checking out! And if you can’t find any toy library in your area then you could always organise to swap some toys with friends or family members.

Even if your child is not up to the same stage as Oli, toy libraries can also be a great way of trialing toys or equipment (e.g: mini trampolines) to see if your child likes them before purchasing. Because we all know how much money we can waste on toys that we think our child is going to like!

Til next time

2. Part 1 – Why ‘Play’ is SO Important for Children with Autism
3. Is there a ‘Magic Formula’ for Autism?

This week’s video tip is self explanatory really.

Again, this is another strategy I use regularly with my private clients that can work quite nicely.

Particularly suitable for higher functioning children with autism (typically 3-6 years old) who are up to the stage where they ‘get’ the basic meaning of situations, but who are then challenged by real life situations where they are required to interpret the complex feelings and thoughts of other people through their words, facial expressions, gestures and tone of voice, then put all of that information together to really understand a deeper meaning of a particular situation.

If this sounds like your child, then you could really benefit from this.

You’ll have no problems doing this at home with your child and all you’ll need are a few of their favourite DVDs

Running time : 15 mins

Brief Overview

1. When is the right stage to introduce DVDs as a tool for building comprehension with your child
2. Why DVDs are such a great tool for doing this, compared to books and other resources.
3. Why it’s so important to choose DVDs that are ‘pitched’ at the right level for your child’s development.
4. How to use both familiar and unfamiliar DVDs with your child to maximum effect
5. To finish off, some insider tips to help you get the most out of this technique.

Question Time

P.S: If your child isn’t quite up to this stage but you would like to learn more about building them towards piecing together all of the information in DVDs, there are SO MANY other visual strategies you can use. Please take a look at DVD 7 from my Autism Essentials Training Program. It goes for over 2 hours and covers virtually all of the other visual strategies you can use. http://www.autism-essentials.com/shop/products/Volumes-6%2C-7-%252d-Learn-Part-1-and-2.html

Hi everyone,

I have to say I’m finding video to be a great way of explaining all of the concepts and techniques that I have to share with you and also for bringing to life many of the examples that will help with applying these tips to your own situation. So I hope you’re enjoying them too!

This week’s tip focuses on how you can improve your child’s articulation and speech clarity skills using a technique called Video Modeling. There are many ways to improve articulation, but Video Modeling is one technique that I’ve found to be very effective over the years with the children I treat.

So anyway, I created a quick, step-by-step guide to show you exactly how you can use Video modeling to help your child’s articulation and speech development. So if your child is struggling with this then I think you’re going to find this video tip particularly helpful.

It goes for about 10 minutes.
