Over the course of the project’s five years, USAID Advancing Nutrition worked to support the U.S. Agency for International Development, implementing partners, and national stakeholders to improve IYCF. We implemented more than 30 activities across the project’s core portfolio and six of its country programs (Ghana, Kenya, Kyrgyz Republic, Mozambique, Niger, and Nigeria). This learning brief summarizes key lessons learned from these efforts and shares resources we developed and recommendations for future nutrition programs.
