If your library has this book:

http://www.amazon.com/Misdiagnosis-..._1?ie=UTF8&qid=1321918049&sr=8-1

I would check it out. I was starting to get the "ADHD" comments about my oldest daughter and even though we home school, I knew I would have gotten them if she were in school. She would be the "bored gifted" you mentioned in your post. But I figured I should prepare for an "ADHD talk" so checked into it and now have great information for discussion as to why she is NOT ADHD.
