S.C.
I have a 6 yr old boy, and at that age it is hard for them to "sit still" I wouldnt worry about anything. I think it is way to early to say a 6 year old has ADD. They wanted to test my oldest which is 10,she doesnt have any problems she's just lazy and doesnt want to do the work. Dont worry give her time to learn how to sit and learn.
