A pediatrician with thirty-two years of experience, Marc Weissbluth, M.D., is also a leading researcher on sleep and children. He founded the original Sleep Disorders Center at Chicago’s Children’s Memorial Hospital and is a professor of clinical pediatrics at Northwestern University School of Medicine. Dr. Weissbluth discovered that sleep is linked to temperament and that sleeping problems are related to infant colic. His landmark seven-year study on the development and disappearance of naps highlighted the importance of daytime sleep. In addition to his own research, he has written about sleep problems in manuals of pediatrics, lectured extensively to parent groups, and appeared on Oprah. Dr. Weissbluth has four sons, two grandsons, and, thankfully, one granddaughter–and they are all good sleepers. Linda, his wife of more than forty years, has provided both inspiration and original ideas for this book.
