To second a comment up above, we were told by a psychologist when D was about 5 that he did not believe she had Aspergers. But at age 15, we recently had a psychologist tell us our D probably DOES have it. He was testing for other things and did not do the actual testing needed for a formal diagnosis, but after reading up on it after he brought it up, I think he is right. We have not pursued the formal diagnosis yet, but probably will so we have it if she wants to request accomodations in college. Her current (private) school is great about accomodations already, so we just haven't had a need for the formal diagnosis. But my point is really that even a psychologist can miss this diagnosis in a 5 year old, so I would at least get a 2nd opinion beyond your pediatrician. Maybe it is not what is going on with your son, of course, but it if is it explains a lot!
