It's Mine by Leo Lionni - Caldecott Medalist
I enjoy this book very much. The characters are human-like in nature which gives the book charm. Lionni captures the essence of siblings in the cute frog characters. The moral is easy to understand and something to remember for all ages, not just children. A definate must have.
