Best explanation I've been given this week in 100 or fewer words:
Each night Brooke climbs into her bed after a long day. (She’s no longer on the floor.) She’s always dressed in pajamas – footed ones with frogs, cozy ones with ballerinas, or my favorite, cuddly fleece ones with monkeys.
Each morning she wakes up and enters our bedroom, rubbing her eyes, announcing “good morning,” and wearing her diaper.
Just her diaper. The pajamas are long gone. Apparently she takes them off during the night. Why be encumbered?
What I like the best is her explanation: “I want to wear my belly button to sleep.”
Apparently, not much else.
