My son was diagnosed with ADHD around age 3 by our developmental pediatrician, who we disliked so much we never returned to again. 3 seemed way too young to diagnose ADHD for me, and he even prescribed medication which we didn't feel good using. (Don't they now say you can't even diagnose ADHD until 6 or 7?!) Since then, he hasn't received any additional services or therapies. I've been very frustrated because this dev. ped. was supposed to be top notch and it took us 6 months to get in to see him. we had a few appts. with him that proved to be useless.
Fortunately, DS's situation now seems to be pretty mild. He's still pretty hyper, which I think is all related to sensory seeking, but it's manageable most of the time. He does well at his school because it's so structured. However, I would like to find another developmental pediatrician to work with. Our regular pediatrician was clueless when I was explaining sensory issues to him.
