thanks for the replys. Sorry, wasn't very clear, my son was six months old when we found out my daughter had aspergers (she was six years old). Being in New Zealand our system is different to the US. At this stage he is too young to be referred to a speech therapist, they would say he may just be behind a bit and to wait. I have talked to my daughters psychologist about it and he said he will keep an eye on him and can refer him later on if he really doesn't take off, he said because my son can anticipate our feelings (he knows we would be annoyed when he gets into my wallet so he takes the wallet behind the sofa to play with it,so he can hide) this shows 'theory of mind', a sign that is not consistent with ASD. He does make a lot of noises and he tries to sing to music, but I can't hear any actual words in most of the sounds. However I know he can hear because if tell him to put something in the rubbish bin he goes and puts it in. His two older sisters do talk for him often, which doesn't help either. It just seems that he is not interested in talking, he is extremely active and only wants to try to climb things, open things, ride on his ride-on car and get into things. He had tons of toys but is not interested in them, except the last few weeks he has started playing with the blocks (stacking them). He can get out of anything (stroller, highchair, cot) so we never get a break from him. He is very good natured and smiley, which is very different from how my aspie daughter was at that age (always distressed, grumpy). I guess I just don't know if I could handle another diagnosis, am still getting over the first one. Also because he is a boy and boys are more likely to have ASD and the likelyhood of it reoccurring because of being genetic makes me over sensitive to everything he does (or doesn't) do.
