What happens when a girl
has the brain of an 8-year-old,
and the body of a 13-year-old?

The New Puberty is a reassuring, empowering guide for millions of parents – as well as teachers, coaches, pediatricians, and family members – by two notable experts in the field. Compiling original research and clinical experience, Drs. Greenspan and Deardorff offer practical strategies for supporting girls entering this complex stage of their lives.

“The New Puberty offers parents and caregivers important up-to-date information, insight, and support about early puberty. It also provides clues for identifying the emergence of more serious problems for girls entering puberty at a younger than expected age. An indispensable guide for helping our early bloomers.”

Chris Hayward, MD, MPHProfessor of Psychiatry, Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine

“The New Puberty is a truly important book. Without jumping to conclusions, this book shows concern without alarm, discusses the scientific factors that could be triggering it, and most important details the psychological consequences that girls might go through, and the support they need.”

Po BronsonCo-author of NurtureShock

“Filled with surprising and fascinating research, as well as practical and empowering strategies, The New Puberty is a book every parent and health practitioner needs to read.”

David Kessler, MDAuthor of The End of Overeating and former commissioner of the US Food and Drug administration

“Increasingly parents are asking why their children are heading into puberty at a much younger age than they ever did. Combining their backgrounds as both scientists and parents, Greenspan and Deardorff give them all of the answers they are looking for. Anyone who has a young girl will want to read this book!”

Cara Natterson, MDPediatrician and author of The Care and Keeping of You 2

“The New Puberty is a treasure trove of information. In it, the authors take a deep dive into the psychology and biology of teen girls. It is destined to become a classic for parents and educators.”
