Yes, as long as they receive appropriate medical care and supervision after they are born, most babies born with NAS can safely overcome their symptoms along with heroin dependence and grow into healthy, functional children. NAS is rarely fatal, though treatment in the hospital may last between one and six months. After babies with NAS are released from the hospital, mothers must properly care for their infants with lots of rocking, cuddling, and swaddling, and must provide them with healthy formulas or breast milk that supports growth and recovery.
