I was privileged to have worked with Berry Brazelton (Fig) for over 40 years. In 1978, as a new graduate student from Ireland, I first looked over his shoulder in the company of his pediatric fellows, as he used the scale he had just developed—the Neonatal Behavioral Assessment Scale (NBAS)—to examine a less than 1-day-old female newborn in the old Boston Lying-In Hospital. Even as he examined the baby’s reflexes, I was immediately struck by his—what could only be called gentleness, even tenderness—in the way he both held and spoke to the baby. He called her by her first name. “You are so alert, Sarah.

She and Berry Brazelton left their mark on me and on all the pediatric fellows who were present on that August day, many years ago. In this clinical newborn encounter, we …
