Today when John got Anne up from her "nap" (she talked and played through her 2 hour stint in the crib), he found her 100%, completely naked. She had stripped down every last piece of clothing on her. Take add a cherry on top of that delectable ice cream sundae, she peed in her crib. (Because, yes, of course, the diaper came off too.)
