My sippy cup

Now that Lucas has taken to puffs, we have tried the sippy cup again. After making faces at it, pushing it across his tray, and throwing it on the floor, he finally figured out how to drink out of it. Good thing we got a picture because he refuses to have anything to do with the sippy cup now. If we put it on the tray, he screams at it and pushes it onto the floor. Oh well, at least they don't leak!
