S.H.
Just wanted to mention that ADHD can not and should not be diagnosed until school age. His brain is changing so fast right now that most professionals would be against meds. I am sure you could find someone that would administer them despite what many think. On the other hand behavioral therapies are most effective with his age and many people use them with medications. You did not mention what behaviors you were experiencing so I don't know what specific sites to recommend. You might want to google behavioral modification and reinforcement and then examine to see if you have a very structured environment. Since you report having ADHD yourself this may be where a professional could be of assistance. I hope your doctor is able to help.
Good Luck
