This Is How I Grow

Explore what it means to be all grown up!

​All newborn mammals—whether they have hooves, flippers, claws, or wings—rely on mother’s milk to help them grow. In order to survive, every cub, calf, and kit must eventually figure out how to find their own food. From bats learning how to fly to elephants gaining control of their trunks, animal families help their young develop the tools they need to hunt, forage, or scavenge. Open this book to explore the incredible variety of skills baby mammals must learn in order to survive and thrive.

How do baby mammals grow? Food! And with a lot of help from their mothers.  


This book shares the life cycle story of eight different mammal babies from habitats across the globe. Readers learn essential facts about each animal’s birth, nursing, weaning, hunting or foraging skills, and other techniques that they must learn from their mother (and community) before they can be “all grown up.”


As they page through the expansive panoramic illustrations, readers explore the vast diversity of the mammal world and learn about those things that unite all mammals. The written text foregrounds the importance of mother’s milk in infancy and learning to find food as each animal matures; the lifelike visual text provides more information about each species, including their habitat, family group, and relative size. The animals in the book are drawn from habitats across the globe and arranged from shortest to longest childhoods.
