I'm new to this forum and also to Asperger Syndrome - my 8 year old son was diagnosed about 3 months ago. I have a ton of questions but will stick to one for the moment. My son, who is in most ways a very gentle and sensitive child, spends a fairly significant part of his day making very loud explosion noises and also pretending to shoot people with imaginary guns, cannons etc. This is okay in the privacy of his bedroom (although it can sound as if WWII is going on in there) but he also makes a pretend gun out of his fingers and shoots at us, or other people, if something happens that he does not like or if he gets annoyed. He seems obsessed with the idea of guns and shooting people / blowing things up although we have never encouraged this. I think the exploding noises are probably a kind of tension release but am concerned about the gun obsession as other people may get the wrong idea about him. Does anyone else have experience with this kind of thing?
