5 year old son Teacher is saying he has the HD part of ADHD?

I didn't read your entire post but I can tell you I am also a parent of a child with ADHD. HD part of it means that your child is very hyper. He has alot energy. Your child school should have performed a "child study team evaluation" to determine if a smaller clroom is better. The only person who can give a medical diagnosis of ADHD is a child neurologist. Oh by the way, I don't believe in medication either. My child has never been on medication. I read up on my child's condition and treat it with alot of patience, behavioral therapy if necessary, and my child has a schedule everyday of the week. My child failed every subject in kindergarten last year my child made student of the month, so just because your child has this condition, doesn't mean he cant succeed and do well in school. It has nothing to do with foods that he eat and how you parent.
