My daughter is this way right now. It's so frustrating.. I'm going to go through this thread with a fine tooth combed this week.. She was easy as pie at two but now she flies off the handle over silly things. She's incredibly bright, has had excellent communication skills since she was a tiny little thing.. but she just makes zero sense now. :| She's also four - just turned four two weeks ago.
