Too early: Two years of age is too early to diagnose a child with ADHD. Also drugging a child to sleep is not wise. Try other alternatives such a Triple P positive parenting program. The program can be done online if you cannot find a group in your locale. More about Triple P positive parenting http://www.triplep-parenting.com/us-en/about-triple-p/positive-parenting-program/
