My 2 1/2 yearold is hitting!

Is she doing it to get attention? In other words, are you giving her positive attention when she isn't hitting? Or does she mostly get attention when she misbehaves? Kids prefer positive attention, but if they aren't getting enough to suit them, they will do something bad to get negative attention. Any attention, even bad, is better than little attention from a kid's perspective. And their idea of the right amount of attention is different than an adult's.

If you aren't already, you should praise her when she does things the way she is supposed to. Even if it's something that you think she should be doing anyway. Look for things to praise her on.
