The WHO Model of Care for Small and/or Sick Newborns (SSNBs) aims to reduce neonatal mortality and address the needs of vulnerable newborns. Three MOMENTUM awards--Country and Global Leadership, Private Healthcare Delivery, and Integrated Health Resilience--partnered with governments and stakeholders in Indonesia, Mali, Nepal, and Nigeria to implement SSNB care models. MOMENTUM Knowledge Accelerator spearheaded a common learning agenda to document the rollout of the small and sick newborn care model (SSNC) in diverse contexts, revealing insights into strategic approaches and technical actions for effective SSNC provision. This resource bundle includes the resources and products that were generated from the joint learning efforts across the suite.
