Terrible twos, temper tantrums, and grocery store meltdowns are usually the first things that come to mind when people think of toddlers. But pediatric emergency medicine physician and researcher Dr. Hasan Merali has long thought toddlers are among the best people in our society and adults could do well to learn from them. These extraordinary youngsters can be impulsive, yes, but with this comes a remarkable ability to take risks and ask questions—two qualities that can help us enjoy life more. To unpack this behavior, he includes many humorous examples from his experience as a pediatrician and father, but the core lessons are drawn from two decades worth of fascinating and surprising studies in child psychology and development. He received his medical degree from Harvard Medical School and Master of Public Health degree from Johns Hopkins University. His writing has been featured on CNN, Science, the Boston Globe, NBC, CBC, and Popular Science.
