Community theatre can be an effective way to support positive changes in health knowledge and behaviour as well as related social norms. This is a guide for programme managers and community theatre groups on how and why to integrate maternal, infant, and young child nutrition content into existing community theater activities. It provides recommendations for strengthening theater performances based on PATH’s successful experience implementing Magnet Theater for a variety of public health topics throughout Africa and Asia, and the Infant & Young Child Nutrition (IYCN) Project’s experience using theater to promote optimal infant and young child feeding practices in Zambia.
