The study aimed to identify feasible complementary feeding practices for caregivers in Malawi during the lean season when food insecurity is highest. Through a Trials of Improved Practices methodology with 36 caregivers, the study found that it is feasible to improve practices in four key areas: providing vegetables, fruits, fats, and increasing food quantities. While most caregivers could not increase animal-source foods, alternative protein sources like legumes and groundnuts were acceptable. Fathers also played an important role in trialing improved practices by providing financial and food resources. The findings will inform the development of behavior change materials to promote improved infant feeding during lean seasons.
