I usually let my kids pick their own snacks, and it makes them feel so grown up! We also play this game where they're the bosses who own a restaurant. They come up with the most creative names for their "establishments," write menus, take orders, prepare the food, serve customers and collect payments. It teaches them so many essential skills and keeps them entertained for hours! And when they finally tire of being bosses, it's easy for me to convince them to help out in the actual cooking process - they become my little sous chefs!
