"Mommy, I have to potty"

Finally, it's sinking in. We've been trying to potty train for MONTHS. Lately he's been saying when he has to pee. Today we're using real underwear. Not pull ups, real cotton, leaky underwear. I'm using my friend's strategy and setting a timer for every 30 minutes so I can ask Alex if he has to go. The thing about him is, if you ask him he'll tell you "no". Going to the bathroom has to be his idea.
