I to have a 8 yr old with alot of trouble staying focused and sitting still, I know part of it is that he likes to daydream but I really think some is due to his meds. I especially notice it when he is on tripple cortone for an infection, he can't sit still and he's okay at reading but if there are alot of words on a page or a long book he can't stay on task long enough to get through it.
