Potty trained?

Before JG turned 2, I started putting him on the potty. I didn't do it all the time, and I definitely didn't make him do it when he didn't want to. Then, when he started Mother's Day Out, they started taking him and he wanted to start trying more at home. The last few days, I've put him in underwear for just a few hours for him to try them out. This morning, when he woke up, he asked for his underwear, and to my amazement he stayed clean and dry all day... even through a 3 hour nap. I'm so proud of him! I'm sure our ups and downs are yet to come, but today we were victorious. (I tried to get a cute pic of him in his underwear, but he right now he screams "NO" whenever he sees me get the camera out).
