I'm using the parent posts because we are wondering IF our 5 year old has AD/HD or not. I, the father was diagnosed around 1993, was very active with Chadd locally and went to a few national conferences back in the 90s. We have a 5.75 yr old girl and with some of the recent emotional outbursts are wondering if its getting time to see a professional. Has anyone had a child diagnosed before 1st grade? I always thought the soonest to check is at 1st grade. Olivia, our daughter, is in Kindergarten.
