This case study provides an overview of two formative assessments by MOMENTUM Country and Global Leadership on current practices, barriers, facilitators, and programmatic approaches affecting the provision of specialized, high-quality nutritional care for small and/or sick newborns (SSNBs) in public health facilities in Ghana and Nepal. These assessments are an important step in expanding the evidence base around SSNB feeding in these contexts and present insightful cross-cutting recommendations to support and/or strengthen breastmilk feeding for SSNBs during inpatient stays and post-discharge.
