caleb has discovered his fist. and he loves it! when it's time for a nap, i turn out the light in his room, he lets out one little "wah" and then immediately stuffs his fist in his mouth and closes his eyes. then, he's ready to sleep! i love it because he falls asleep on his own, he can fall back asleep if awakened mid-nap, and his fist never moves away like the pacifier does.
