Rest of Their Lives: A Practical Sleep Guide for Healthy Kids and Thriving Families (From Birth to Early Adulthood)

A practical, science-backed guide to optimizing children’s sleep development—from birth through early adulthood—by one of the world’s leading pediatric sleep specialists.

Sleep is one of the most important forces shaping a child's development. It influences brain growth, learning, emotional well-being, behavior, and physical health—yet it remains one of the most misunderstood aspects of childhood. Whether improving sleep health or when sleep problems arise, parents are often left navigating conflicting advice, internet myths, and endless trial and error.

In The Rest of Their Lives, pediatric sleep specialist Dr. Daniel Lewin draws on decades of clinical experience and groundbreaking research to explain how sleep evolves from birth through early adulthood, and what parents can do to support healthy sleep and development every step of the way. Central to his approach is the concept of family sleep health: the understanding that a child's sleep never exists in isolation, and that healthier sleep strengthens not only children, but the well-being and resilience of the entire family.

Warm, wise, and deeply reassuring, The Rest of Their Lives is more than a guide to better sleep. It is a road map to raising healthier, happier children while cultivating calmer, healthier, and more connected families.
