Thanks for those book suggestions, Indigo, they sound quite helpful. I'll add them to my ever-expanding DC library.

Dude, you are right about the perfectionism and anxiety. DS & I are about to embark on a joint project with What to do When Good Enough isn't Good Enough (perfectionism runs in the family). Which factors in to my concern about having him think he's dreadfully flawed if I add social perceptions to our agenda.

DS is struggling with EF in the classroom and I don't think we'll make much progress there until he acquires greater insight into how his behaviour is perceived by others. Upon reflection that's a much more compelling reason to work on his self awareness than general social interactions - he's part of a happily weird family, so we're probably reinforcing his oddballness! I shall try more social situations conversations and see how he reacts. Thanks for the suggestion.
