The investigators will conduct a cluster-controlled, stepped wedge implementation science trial of a bundled reproductive, maternal, neonatal, and child healthcare (RMNCH) delivery intervention within an approximate population of 300,000 people in rural Nepal. This intervention integrates five evidence-based approaches for reproductive, maternal, newborn, and child health focused on the "golden 1000 days" from conception through age two: 1) Community Health Worker model of home-based care to monitor and increase utilization of services, maternal and neonatal health knowledge, self-efficacy, social support, and emergency planning among mothers; 2) Continuous surveillance of all pregnancies and children via an integrated electronic medical record; 3) Delivering community-based integrated management of newborn and childhood illness (CB-IMNCI) via CHWs; 4) Group antenatal and postnatal care to improve care delivery and reduce mortality during the "golden 1000 days" from conception to age two; and 5) Balanced counseling to increase post-partum contraception.
