Usually it's individual items being taken from the lunchbox, mostly at lunchtime at the table, although the entire lunchbox was stolen from the cafeteria as well once or twice. She started saving all of her trash until the end and throwing it all away at the end. Additionally, she has gotten permission to keep her lunchbox in her backpack until lunchtime instead of putting it in the cafeteria with all of the others. Her most "healthy - looking" (i.e not as much fun) items usually get left alone, but making it all look boring makes her less likely to want to eat it even if it's more likely to be there when she's ready for it. Also, having to save her Babybel cheeses and the fruits she gets to pick out for herself until after school seems like a punishment to her. She works so hard to earn the right to choose her lunch snacks at the grocery store and I don't want to undermine that privileged if I don't have to. Packing a spare sandwich that will keep all day separate from her lunchbox is a good idea, her backpack has an insulated pocket on the front just large enough for a sandwich and sliced fruit.
