Nap on the Rocks?

The above photo captures the essence of Daniel's nap this afternoon: An hour of singing and playing (and unbeknownst to me, tossing every stuffed animal, blanket, pillow, and book out of his crib onto the floor), followed by a half-hour of him calling, "Mommy! Mommy! Mommy!" He finally exhausted himself and fell asleep in his empty crib. Two hours later, when I went in to get him up, this is what I found. The look on his face was a cross between, "What did I do?" and "Who, me?" I have a sinking feeling that naptime is an endangered species.
