A guessing-game introduction to animal tracks . . . and the baby animals who make them!In this adorable introduction to animal tracks and habitats, a trail of paw, hoof, or flipper-prints wanders across the page, followed by a question: who made these tracks? Thirteen different species are represented, introducing not only their signature tracks, but what their young are called, and a fact about their behavior. On the final pages, some very familiar footprints are followed up by the question "Who learns to walk on two feet?" A baby, of course! With its simple question and response pattern, Step by Step is suitable for very young readers who will delight in guessing the answers and turning the page to uncover adorable baby animals. The hardcover edition includes backmatter with bonus facts about the baby animals pictured-- from caterpillar to human. For the very youngest readers, a board book edition is also available.
