I decided that since DD was with MIL and we had a playdate planned for my house today, we'd try going straight into underwear and see what happens. Well, he did AWESOME. He had a couple accidents in his underwear before nap, but woke up completely dry from nap and didn't have any accidents all afternoon! We put him to bed in a diaper, but after a couple potty runs I decided to just keep him in underwear. I'm going to wake him up a bit before I go to bed to try the potty, and see what happens in the morning.
I'm so proud of him, and surprised he did so well! I can't believe my little man is getting so big.
