Hi all.
Here is a post and video we put together on - How to teach a child with Autism using ABA techniques and the power of positive re-enforcement.
Hope it helps in some way.
Also there has been a lot of activity on the web page re: the Adelaide Autism School, hopefully something will come from it!
