Smug. Again, sorry to hear what you are going through. We have similar goings on at the moment.
I have been on 2 Webster-Stratton courses so far. I've actually enjoyed them, and some of the reward systems do work for a certain time (until my DS starts demanding bigger and better rewards). All these strategies tend to be short lived in my experience but I have to say consistency is the key to even a short length of success.
Following four months of assessments we have been told my son has something, but the Pscyhologist does not know a name for it! She says from my descriptions he has ASD, but during ADOS and School observations he is not. the psych and I am at a loss and quite confused. He has been diagnosed with food phobia, and anxiety has been mentioned.
I have also asked the question of early intervention. The psychologist has told me that early intervention only really counts for classic autism, as opposed to High Functioning/Aspergers etc, so she's told me not to worry too much on that score. She has said that even if we did get a diagnosis of HFA/Aspergers (she's referring us for a 2nd opinion), then not a lot would be different for us. She said there's no guarantee of a statement at School for example.
One thing the Psychologist said was that you can apply strategies that work with ASD children to any child as it is the ASD child who will be most challenging. So I don't get the strategy you've been told, as treat them like a normal child. For example, if you were telling my DS that his plate of food was all he would get that week, would he eat it? Absolutely not! His teacher has said the more pressure you put on him the less he complies.
while I don't want my DS to have a label for the sake of it. I constantly have to apologise for (what seems like) him being ignorant. Selfishly, I want to know what it is! I have just gone down the route of private assessments also (for dyslexia etc) - just waiting for the quotes.
I wish you all the best.
