C.S.
I have a 6 yr old boy with ADHA, for the most part he does just fine in school.We did put him on meds for school but he only takes it for school we don't give it to him on weekends or during summer. He does have to have more reminders then most kids and directions have to be broken down into smaller steps. But other than that kids with ADHD/ADD are normal little kids.
I would suggest finding a behavioral psychologist in your area. Our pediatrican gave us some suggestions for good psychologist. They will just help give you ideas on how to modify his behavoir and your parenting to down play the ADD.
