Neither one of us was anywhere near the girls' room when I heard their door open. Squeaker came out into the hallway looking for Daddy. Eventually we got her back into her bed, but then she climbed out again and closed her bedroom door (we keep the door open the tiniest bit in case we have to go in when one of the girls is sleeping and the other is not). She and Muffin were playing "Muffin takes things out of her crib and hands them to Squeaker, who puts them back into the crib," which, while fun, was not the point of going to bed.
Ah, the joys of having two-and-a-half-year-olds.
