I have a six year old who is the same way. We've actually started referring to his "time of the month". He will have a week out of four where he is just off the wall. Very hyper, wakes up that way, and little things set him off. He will then have a fairly even temperament (not an angel, but not acting crazy either) for several weeks.

We took him to be diagnosed when he was a little younger and he really didn't fit any category. The actions have to be consistent to warrant ADD or ADHD. We've found the older he gets, there seems to be more space between the hyper periods, but I sure would love to know what sets him off!

His is every day ,only time he his quiet is if i sit with him or if he is doing something .But it does not last for long.
