The good, the bad, and the potty

Here's the interesting thing about David's budding potty habits: he will typically go without complaint - but many mornings when he gets up he refuses to go and has a huge tantrum over it. Other than in the morning it's not typically a problem, and he's getting better at it as well. Our one friend is lobbying heavily for us to just go straight to regular underwear (and stop using pull-ups), but we're very reluctant to take that risk in our house. So far it hasn't really motivated him and just creates more mess.
