I found out this morning that a certain four-year-old has been having two breakfasts every day and hadn't mentioned it. I didn't notice on the Pre-K schedule that, as opposed to the other kids in school, they have breakfast in their room every morning at 8:15. I'd been feeding her (and the other kids) breakfast at home each morning before school.
So either we don't feed her enough, she eats too much, or she's a Hobbit. Clever, nonetheless, not telling anyone about Second Breakfast.
