A book that acts as a visual yardstick for preschool children to gauge just how much they've grown and learned since they were babies. It begins with a full-color group photo of six winsome preschoolers juxtaposed against their individual baby photos. A series of vignettes follows, each one focusing on the dependent infant the child was and his or her contrasting accomplishments now. Readers see each of them revel in the realization that ""Now I'm big!"" There is an element of mystery to the story: matching the initial baby photos to the grown children in the group shot. Miller (My Five Senses, 1994, etc.) offers a simple concept, carefully executed, that will reinforce all children's sense of mastery of basic tasks.
