Cadberry's mom is very forgetful. Every time they visit his doctor together she talks about C & F. She never remembers the other letters. When Cadberry draws a set of letters to help his mother remember them all, he discovers what C & F really mean and how those two tiny letters affect so much of his life. Developed for pre-school-age children, Cadberry's Letters uses simple, easy-to-follow language to explain Cystic Fibrosis and the daily care that goes along with it in terms young children can understand. Children will learn along with Cadberry about things like Pancreatic Enzymes, Chest Physical Therapy and more. Bright, full-page illustrations bring the story to life and feature a lot of the equipment and medications CF patients may use in their daily lives.
