It can take a lot of 'nagging' to get help...

My son is now grown up. He was diagnosed with Aspergers at the age of 9. At primary school level he had a dual school placement where he spent some time in the Centre for Autism and the rest of the time in a mainstream school. This worked very well but it took a lot of "nagging" to get help. In fact, the worse he behaved, the more help we received. If he hadn't been troublesome in the classroom I believe he would have been left forgotten in a corner. The Ed. Phsch. once came to see him in school and he behaved fantastically. When the same professional came to assess another child she saw what my son was really like and we got the help.
What I am really saying is NAG, NAG, NAG and put forward your worst scenarios as evidence to all the professionals. Never feel that you are being a problem.
My son ended up with 7 good GCSE's and went on to college. He now has a well paid job but, sadly, only one friend. My big wish in life is that he gets friends and builds good relationships.
