A photographic paperback series designed to introduce the fascinating world of animals and how they develop. Appealing step-by-step photography allows children to see a butterfly emerge from its cocoon and spread its wings, or see what happens when an egg hatches and a chick emerges. Each book comes with a sticker sheet packed with cute images of the animals featured in the book. See How They Grow: Lamb follows a lamb on its path from newborn to adult sheep.
