22 month old little boy with bad behavior.

Hi!  I have a 22 month old son who can be as bad as he is sweet!  He is constantly moving and never wants to sit still except for when he is ready to take a nap or go to bed with an occasional break to lay down in his bed and watch Dora or Blues clues.  He constantly says NO and smacks at the air, himself, myself, my husband, my daughter, the dog or whatever seems to be around at the time.  He screams A LOT!  He has had screaming fits during the night that almost seem to fit the description of a night terror and has a couple of instances where he would scream out NO and I would think he was awake and I wold walk in his room only to find him asleep!  He seems to get bored very easily with toys.  I have often thought that he could possibly have hyperactive (adhd) but have read that no one wants to try to diagnose that at such a young age.  I don't know what to do and sometimes feel like I am at my wits end.  His pediatrician won't listen to me and says it is just attention getting behavior...I just don't believe it and have other people comment they don't either.  Please Help!

This is common behavior for this age, he is learning boundaries and who's boss.  Kids this age also will yell out something while completely asleep just like we will talk in our sleep.  Night terrors are common and it sounds like he is having these as well. They are caused by a lack of sleep so make sure he gets in a good nap during the day.  Are you disciplining him for bad behavior and rewarding him for good?  You can try "time out," and always get down on his level, when talking to him and tell him "we don't hit others" or "we don't scream."  A 22 month old is a very busy guy and always on the go, so at this point I wouldn't be concerned.  He does a lot of things because he can!  He needs to learn that we don't act this way.  He understsnds much more than he can speak right now, so always tell him why he is getting time out.  Then renforce why he had to be in "time out" and end it with a big hug and an I love you.  He's learning the ropes, what is allowable and what isn't.  When he screams you may try totally ignoring him, not even a look, when he sees this gets him nothing, he will stop.  I think he is a normal 22 month old, and truly wouldn't worry at this point.
