Just wanted to (fourth?--and fifth, based on my sister's experience with her DS7) previous comments about getting an independent eval. I know we tried to be seen as 'team players' by using the school-recommended psych last year, but the eval totally bit, being based as it was on questionnaires from the teachers who pretty much couldn't stand DD (in contrast to the previous two teachers who were wonderful with her while being completely honest with us about her various issues, Bless them). And we're still trying to get a 'fair' evaluation, and I'm still trying to not bug people on this forum by posting about this issue over and over again
So best of luck to you.
BTW, one view of Asperger's apparently is that it can manifest as impulsivity b/c one is not so concerned with what others think.
