 The paper reflects on the implementation progress of breastfeeding, complementary feeding, and young children's malnutrition strategies and programs in Brazil, using the RIM framework to analyze implementation barriers and facilitators. Common challenges include unclear goals about program reach, difficulties assessing effectiveness and fidelity during implementation, discontinuation, or lack of funding, and insufficient monitoring and evaluation impacting sustainability. The paper suggests that high-quality implementation research is necessary to catalyze progress towards achieving adequate nutrition by 2030.
