This document discusses the Care Group approach used in an intervention in Nepal from 2005-2010. It aimed to shift social norms around maternal and child health issues through community groups. Formative research identified key norms and barriers. Community groups engaged women to reflect critically and root issues in community values. Evaluations found sustained impact on behaviors like breastfeeding years later. Challenges included focusing directly on norm drivers and unrealistic community health worker workloads. Further research on accurate norm assessment and evidence-based norm-shifting is still needed.
