Violence exposure can negatively impact early childhood development (ECD), yet limited research exists in low- and middle-income countries (LMICs). This study aimed to determine what effective integration of ECD plus violence prevention (ECD+VP) can look like in LMICs. Seventeen key informants were selected using purposive sampling, representing U.N. agencies, donors, implementers and research organisations. Using open coding of semi-structured interviews, the authors identify five priority areas for promoting an integrated ECD+VP agenda: (i) parenting and parent child relationships, (ii) family systems, (iii) development in an ecological context, (iv) system strengthening and integration, and (v) building and translating evidence.
