I'm so dealing with this too. The funny thing will be that he will wake up in a cantakerous mood and I know its going to be a high drama day of screaming and yelling. Then the next day he will be in fantastic happy mood.
Thursday was a bad day. He dropped a toy at his own feet (not on but next to his feet) and he started screaming like he was hurt. I had to tell him it was ok and all he needed to do was pick it up. He did and he was ok for a few moments until the next major tragedy.
