Lo and behold, he was on his stomach at the foot of the crib! This is the first time that he has rolled over and woken himself up while napping. Normally, he stays pretty centered and on his back while in his crib. My guess is that he was so excited about his new-found skill that when he finished his first sleep cycle (they are 45min each) instead of putting himself back to sleep and sleeping for another cycle, he decided to do some practicing.

How funny. This seems to be the start of a whole new world to come! Wish us luck! Time to buy some baby gates and start being more diligent about vacuuming! YiKEs! -- mam
