I would recommend this book for any parent who has a child on the autistic spectrum.Jon and Polly Tommey have dedicated there life towards helping there son Billy and have had wonderful results, they have over the last few years used there expertise to help other children ( mine included) . The ratio of children on the autistic spectrum is 1:59 , and no doubt will increase , the government need to listen to people like Jon & Polly , they may even save some money!?!
The Autism File magazine is also a very useful read, there are many therapies and interventions that can help children with A.S.D.
