Dr. Marc Weissbluth, sleep expert and author of Healthy Sleep Habits, Happy Child, returns to the Y next week to share the science of slumber in two talks for parents, Sleep Smarts and Twins. The video above is from November 2007 when he hosted a panel of parents at the Y to talk about effective strategies for establishing healthy sleep patterns for their children—and themselves. These smiling parents are the best indicators of how good his advice is.
