My son is gifted and has ADHD. It's sort of apparent. He has learned some coping methods on his own for controlling it. He'll clinch his fists and push himself to the point of shaking.... he says it makes him feel better.

In school he is able to complete his work and the teacher is aware that he has it. He's in 3rd too. His teacher is very tolerant of "wigglers", there are quiet a few kids in his class that have it.

As for the age thing, he's 7 and is sort of out of place. Most of the kids in his class are 8 or 9. There are a couple who are 10 and I think one boy is 11. But he goes to a typical public urban school.
