Join three babies as they grow more and more active with each day—crying, smiling, nursing, teething, rolling, crawling, walking, and talking—culminating in a birthday celebration for all the kids. In this book for prereaders, Michael Emberley's skillful pencil illustrations capture the restless energy of toddlers, while Nancy Raines Day's rhythmic, rhyming text is a whirlwind tour of the babies'—and parents'—first year.
