RE: Hitting
There's good info in the Sears links. I think I have tried most of those things at various points in time. As someone said, sometimes something works and sometimes it doesn't, so having a repertoire of things to try is good. I have almost always found that hitting correlates to her being tired or hungry or frustrated. But you know, sometimes when she's tired I still may HAVE to go to the grocery store, and I don't want to hit me then either.
Now that she is older and is more verbal, I have found that talking about her feelings really helps. When she seems like she is going to hit I will say something like "you seem angry" and she will usuaully then try and talk to me about what she is feeling. And lately she has even begun volunteering "mommy I am really angry!" which lets us discuss what she is feeling and why. But I think that just over 2 is too young to expect this.
Good luck. I know its super frustrating...
