Paul has been SOOOOOOOOO naughty lately, and I don't know what to do! He's two, and he really is TERRIBLE. Today at the grocery store, he bit Katie, not once, but TWICE. He's never done that before. Not to mention all the kicking, hitting, pushing, etc. I was very clear that this was unacceptable behavior and I separated them, but there's only so much you can do at the grocery store, KWIM? He's obviously exhausted, but he refuses to nap. This is a new thing for him. Then he's miserable the rest of the day and I feel like I'm always angry with him. He's blatantly disobedient and goes out of his way to disobey the moment I tell him that something is bad. Nothing I say or do to him seems to make any difference. He seems to think it is all one really funny joke. We've tried time outs, removing privileges, separating him from others, excessive praising of good behavior...Please tell me this is just a stage! Do you have any suggestions? I just feel like I'm not getting through to him at all.
