Oh No for Mommy!

Today I was trying to study for my Geography test today. I have to memorize places on the map. While I was studying, Katie was entertaining herself with her toys for half an hour. When I was finished, I needed to get Katie ready so that my Mom can watch her while I go to class. I took her into the bathroom to give her a bath, and noticed her diaper wasn't on! She took it off of herself! I'm so bummed she knows how to do that! lol. I don't want her doing it at night and peeing in her crib :( Depressing lol. Then when I asked her "Where's your diaper?" She smiled and layed her head on me. Great, she also knows she's cute, and how to use it :/ lol
