Thank you for the reply.
I really appreciate your advice.
The school knows the diagnosis, but no one else. My husband and I are beginning to think it's time to share the diagnosis with our son. Funnily enough, our son has said to us "my brain is different to other people's" so it may be helpful for him.
I just don't want the diagnosis to get round the playground at this stage, as it may make it even harder to get kids to play with him, and I don't want the sympathy vote!
I have ordered a kids adventure book featuring a boy being diagnosed with Aspergers, and I will preview it. If suitable, I may give this to him and see if he recognises himself as being similar, and it may open up the discussion.
I am not at all ashamed of the condition, I love the way my son is, but I want to smooth his way in life. If he had extreme behaviour, then I would be shouting about it, as a useful explanation! But as people may not notice, I'd rather give him the option to stay undercover for now.
As he is rarely chats to other kids, it's unlikely that he will spread the word around himself!
