Haha, wait...cereal isn't proper?! ;) Breakfast is served at schools here, so they usually only have cereal on the weekends. But it's great that you are teaching your girls to notice when foods are running low. Little tasks like that help build their self-reliance for sure! My 7 year old loves to help make the grocery list before we go shopping, though there are usually some of his choices on there too...Ice cream, candy, etc :)
