Leonard Sax argues that rising levels of depression and anxiety among young people can be traced to parents abdicating their authority. The result is children who lack self-control, who look to their peers and to social media for direction. Sax shows how parents can and must reassert their authority—for example by limiting screen time, by prioritizing the family, and by teaching humility and perspective—to renew their relationships with their children. In this new edition, completely revised and updated with new stories, new evidence, and new recommendations, Dr. Sax provides concrete guidance for parents seeking to help their children fulfill their potential in the midst of a toxic culture. Sax offers a blueprint parents can use to help their children thrive in an increasingly broken world.
