Climbing out of the Crib

I wondered when it would happen, and now it has. Mace can climb out of his crib now. About an hour after I put him down for a nap, which is how long it takes sometimes for him to fall asleep, I finally went into his room because he was being so noisy! He was singing and banging on something. When I walked in, this is what I saw.

Interestingly enough, he doesn't climb out all of the time. He still sleeps in his crib really well, but if he doesn't fall asleep within a half hour, that's usually the time he starts banging and singing and climbing. :o)
