M peed in the potty!

I can't even believe it! For the past couple of days M has wanted to use the potty. Every once in a while (about 3 times a day), he will say "potty, potty." So, I encourage it by taking him right to the potty and letting him sit. Well, today right before nap when I told him we were going to change his diaper he said, "potty, potty." and off we went to the potty. Then he did it, he peed. Big brother E was so supportive and proud of him saying, "What a big guy you are now M. You need some big guy underpants now." Then he went on a search for some big guy underwear for M. We found some of E's that were too small in the basement and E gave them to M. I put them on right over his diaper but he was so happy. We'll see what happens but it's an exciting day at our house.
