My little stinker of Izabella

Izabella has been doing very well in her big girl bed, no more crying when going to bed or taking a nap. But this afternoon after her nap, she knocked on her door as she normally does to let me know she is up and ready to get out. But this time when I went to go let her out of her room, she had locked her door. So of course I had to get a butter knife to unlock it, and when I opened her door, oh let me just tell you, she had made a BIG mess. When I asked her what had she done, her reply: All done... What a little stinker.
