little houdini

This weekend we put Annabel down for a nap and then put the monitor on in the living room. After a long while I realized the static that had come through was continually uniform and I wondered if the transmitting monitor was off. Yup. As I got close to the nursery I heard her insistently talking, not quite crying, so I assumed she'd been up a little while. When I looked into the crib this is what I saw:

We put her down dressed in a onesie, and somehow it was completely off and still snapped. It's a 3-6 month size so not too big on her. How does this happen? What I wouldn't give for a video of this!
