Essential newborn care involves a comprehensive set of interventions before conception, during pregnancy, at birth, and in the postnatal period to improve newborn health outcomes. It includes clean delivery practices, temperature maintenance, early and exclusive breastfeeding, detection and treatment of problems, and special care for low birth weight babies. The goal is to reduce the major causes of newborn deaths like birth asphyxia, infection, and hypothermia through basic preventative measures and early detection and management of complications.
