Where did you get those?

Dave and I are trying hard to get Caitlin to eat the same meal we are eating. Suddenly she refuses and throws herself on the floor, even when the meal is something she usually likes. Last night, we told Caitlin that she had to eat her pasta (plain with cheese on the side) before she could have dessert. She was having a temper tantrum and left the room. When she came back she was eating animal crackers! I asked her where she got them. She answered so matter-of-factly, "Preschool." Apparently Caitlin is hoarding food for just such occasions.
