Here are some great books for helping kids understand celiac disease. We have found these books to be a great resource around our house and are often requested bedtime stores. They are all very much written with kids in mind and are easy to understand. I also know of several parents who have used these books in their childs classroom to help the other children better understand celiac disease. I have included links to where you can buy them. These may also be available in your local bookstore.
