Marc Weissbluth

From 1973 to 1978 Weissbluth practiced solo general pediatrics in Chicago’s Chinatown. In 1978, he joined the full-time faculty at Children’s Memorial Hospital, and did research on sleep in children in the Sleep Disorders Clinic that he founded. In 1983, he returned to private practice and founded The Northwestern Children's Practice.

He conducted research in children’s sleep and discovered associations between infant colic and infant sleep and separately, between temperament in children and children’s sleep. His research also showed that moving the bedtime earlier significantly reduces the frequency of night awakenings in a child. In the Sleep Disorders Clinic, he developed a program consisting of several separate elements to help parents solve their child’s sleep problems. He called this program "sleep training", a term he introduced in Healthy Sleep Habits, Healthy Child. Subsequently, this term has been popularized as shorthand for a specific sleep solution called ‘extinction’.
