Don't overlook gluten-free foods for kids! Case in point — this EnviroKidz Organic Amazon Frosted Flakes Cereal ($5/box). This cereal is tasty and made from gluten-free ingredients like organic corn meal, organic evaporated cane juice, and sea salt. It's also fat-free, USDA organic certified, and is probably one of the nearest matches to Kellogg's Corn Flakes you'll find available.
