[quote=epoh]. I would love for him to find another little boy like him, but we haven't come across anyone quite so obsessed with Legos/Star Wars/Diary of a Wimpy kid!

Aww, epoh I feel your pain. My DS8 is not ADHD, but has SPD (sensory seeker) and I am constantly worried about how that effects his ability to make friends (he touches people too much, invades personal space). But I have to say that he has gotten so much better at controlling his urges lately and he seems to be doing much better socially at school. Seven was hard, 8 seems to be going much better.

And I just want to suggest that it is not your DS but the other kids at the school who are unusual in their interests. Almost all the boys this age that I know have some level of obsession with Legos/Star Wars/Wimpy Kid! Yes, they talk sports too, but there have to be some kids that share his interests around! I would talk with the teacher and share your concerns about his social interactions. She may have some more insight into the issues and also may be able to silently intervene (by pairing him for a project with someone she knows might be a good friendship fit, or rearranging the seating, for example).

Also, maybe you can work with him to share his interests as well as listen to others. So, for example, my ds loves chess and he will sometimes teach friends how to play if they are interested. But honestly, social relationships for boys are hard at this age, IMO. None of them, not just your ds, have learned really how to be a friend, they are all figuring it out.
