When David Sobel's children were toddlers, he set out to integrate a wide range of nature experiences into their family life, play, and storytelling. Blending his passion as a parent with his professional expertise, he created adventures tailored to their developmental stages: cultivating empathy with animals in early childhood, exploring the woods in middle childhood, and devising rites of passage in adolescence. This book is Sobel's vivid and moving memoir of their journey and an inspiring guide for other parents who seek to help their children bond with the natural world. As we share this family's experiences, we observe how wild play in nature hones a sense of wonder, provides healthy challenges, and nurtures Earth stewardship -- and we share Sobel's joy as his children, Eli and Tara, grow into earthbound, grounded young adults.
