Nancy is a preschooler who is tired of being the nondescript child in the middle. Her older sister is big; the baby, whose gender is never identified, is small. The comparisons continue--straight and round bodies, dark and fair skins, and first and last in bath order. But the concepts are confusing, unconnected, and oversimplified, with little in the text or pictures to help preschoolers relate to the abstract ideas. Nancy finally gets fed up just in time to celebrate the fifth birthday that supposedly resolves all her frustrations. This is a marginal picture book, except for the fact that Nancy's family is black, lives in an integrated neighborhood, and is shown doing everyday activities. But even collections with a dire need for this type of material will want clearer, better-constructed concept books for their readers.
