**Core Concept**
The Reproductive and Child Health (RCH) program is a comprehensive approach to improve maternal and child health outcomes in developing countries. It focuses on providing essential services for women, children, and adolescents, with a holistic approach to address their health needs.

Maternal Health focuses on reducing maternal mortality and morbidity through antenatal care, safe delivery, and postnatal care. Child Health encompasses immunization, nutrition, and disease prevention, while Newborn Health addresses neonatal care and prevention of early childhood mortality.
