While sitting on a hill, a mother tells her young son, "You are so big," beginning a whirlwind tour of the natural world in which the boy is told that he is bigger than a toad, a desert hare, and a porcupine. Skillfully capturing the likeness of some favorite animals, Joseph Kuefler then depicts all the things that the boy is smaller than: a bear, an iceberg, a blue whale, and the stars. The final message of this beautifully produced book for readers 4 to 6 is that love between parents and children is that love binds us all together.
