In this delightful book the reader follows six-year-old Nicole, an excited brand-new big sis whose brother has been born six weeks early and is now a new patient in the neonatal intensive care unit or NICU. Nicole goes on a tour of NICU with Dr. Terri, the neonatologist, and learns all about the world of preemies, which is now the new world of her little brother, Charlie. This book will delight anyone who has had a premature baby, any sibling who has a brother or sister in the NICU, any former preemie wanting to know more about their first few days, and anyone who works in the unique world of the NICU.
