Finally, I want to remember my late mother, Dr. Janet Sax, who, as a pediatrician, devoted her professional life to teaching parents how to guide their children. In the years before her death, she and I had countless conversations about the topics I address here. She had a vast depth and breadth of firsthand experience with children and adolescents acquired in more than 30 years of clinical practice. Throughout the book, I have often wondered, What would Mom have said? Wherever you are, Mom, I hope you like the book.
