Thomas Berry Brazelton (born May 10, 1919) is a noted pediatrician and author in the United States. Major hospitals throughout the world use the Brazelton Neonatal Behavioral Assessment Scale (NBAS). Many parents know him as the host of a cable television program What Every Baby Knows, and as author of a syndicated newspaper column. Brazelton has written more than two hundred scholarly papers and twenty four books. His Columbia Alumni Profile describes him as "America's most celebrated and influential baby doctor since Benjamin Spock" (also a Columbia alumnus).
Brazelton was born in Waco, Texas. He graduated in 1940 from Princeton and in 1943 from the Columbia University College of Physicians and Surgeons in New York City, where he accepted a medical internship at Roosevelt Hospital. From 1945, after war service in the U.S. Navy, he completed his medical residency in Boston at Massachusetts General Hospital (MGH) before undertaking pediatric training at Children's Hospital of Boston.
He entered private practice in 1950, in Cambridge, Massachusetts. His interest in child development led to training in child psychiatry at MGH and the James Jackson Putnam Children's Center. He subsequently served as a Fellow with Professor Jerome Bruner at the Center for Cognitive Studies at Harvard University, then combined his interests in primary care pediatrics and child psychiatry and in 1972 established the Child Development Unit, a pediatric training and research center at Children's Hospital in Boston. Since 1988, he has been Clinical Professor of Pediatrics Emeritus at Harvard Medical School.
Brazelton was president of the Society for Research in Child Development (1987–1989), and of the National Center for Clinical Infant Programs (1988–1991). He has appeared many times before Congressional committees in support of parental and medical leave bills, and continues to work with the Alliance for Better Child Care for a more comprehensive day care bill. He is a co-founder of Parent Action and serves on the National Commission on Children.
Brazelton has appeared several times on The Oprah Winfrey Show and Ellen DeGeneres Show.
