I agree completely with the posters who've said the crying might have more to do with intensity/sensitivity than with maturity. My DS6 started kindergarten a year early and still cries sometimes in first grade, but he's also a self-critical perfectionist who really takes things to heart. I see this all as part of the gifted package, but even my husband will occasionally tell my son he's too old to be crying over something, so I wouldn't expect a lot of teachers to know the difference between the two. I think it helps if, when a teacher brings up crying, you say something like, "Yeah, he has really strong emotions." It might help him/her look at things in a new way.
