6Every year, nearly 4 million babies are born in the United States. Most arrive safely and go home with their families in a matter of days. But not all babies come into the world healthy and almost half a million arrive well before they are expected. These newborns need tiny medicine. Told from the first-person perspective, Dr. Chris DeRienzo--a neonatologist, health system leader and frequent keynote speaker--walks readers through the human experience of caring for the world's smallest and sickest patients. His stories share the absurd and the sublime parts of being a doctor and detail how they have shaped who he is as a husband, father, and person. Readers will learn the secrets of the NICU, the loneliness that comes with life and death decisions, and the incredibly powerful sense of purpose and triumph that comes with just making it through the night and keeping everyone alive. In the end, this book delivers an insider's view of a doctor's life never before accessible without a white coat.
