hi annie, i too have had similar concerns about my son eg innapropriate behaviour, talking in a silly voice, not a good mixer, high level of intelligance etc Then i was recommended a book to read by Gael Lindenfield (i think the surname is spelled correctly?), called confident children or words to that affect (i'll check it later if u like), and it listed so many of my sons problems and said that actually it was all low self esteem and confidence. weve worked on him a bit in terms of confidence and he's sooo much better, and i dont have any concerns, hes just shy. I have also read that children can have aspergers "traits" but not nececsarily be an aspergers child. I believe that aspergers children have more problems in terms of taking what you say literally, for example, if you asked a child with aspergers, where did they go on the train....they may answer, down the track. or you might say, put a sock in it and they wonder where to put the sock, literally. hope this helps.
