Carolyn D’Ambrosio, MD, FCCP, returned to Yale School of Medicine on July 1, 2021, as vice chief for fellowship training and the pulmonary, critical care fellowship program director in the section of Pulmonary, Critical Care & Sleep Medicine.

“My interest in infant sleep happened here at Yale 20-plus years ago, and here I am 20 years later, not just returning to Yale, but in the same year that I finally wrote a book on infant sleep,” D’Ambrosio said. “It’s really interesting to me how that coincided.”

As a new parent, D’Ambrosio said she realized that the recommendation to leave a newborn or an infant in a “dark and scary,” room to cry themselves to sleep “just felt wrong,” she explained. “It’s been a 17-, 18-year process where we’ve talked to parents and other experts, we’ve looked at the data and research, and we’ve concluded that there’s really nothing to support those recommendations,” she said.
