The home environments in which children are raised fundamentally shape their health, wellbeing, and development outcomes in early childhood and throughout their lives. Exposure to violence in the household is linked to poor health and development outcomes and intergenerational cycles of violence. Bandebereho is a gender-transformative intervention in Rwanda that helps new parents to become more equitable, caring, and responsive caregivers. The intervention is proven to reduce violence within the home and to foster men’s engagement in their children’s lives. When implemented at scale through community health workers it has the potential to reach all newly expectant parents and to positively impact child development for thousands, if not millions, of future children.
