I'm new here, looking for anyone with experience with ADHD in 2-3 year olds.  My son has autism and (I believe, though never diagnosed) ADHD.  His behavior and hyperactivity is getting progressively worse, despite intense behavioral therapy, so we are going to start him on dexedrine asap.  I guess I'm wondering what to expect? Any success stories for that age? Any weird side effects? TIA!
