Thanks! I will check those books out.
My sister has ADHD, so it does run in the family.
When he was in Kindergarten (before I did the research about giftedness) he was taking some ADHD medication for a short period of time. He was a holy terror while on it. He got violent and had a hateful attitude...this was far off base from normal behavior. The medication was stopped and will not be given to him again. That is another factor in my thinking that maybe it wasn't ADHD after all. Hopefully your book reccomendations will shed some light on the situation for me.
