Grandparents whose grandchildren are exposed to domestic violence are faced with some unique challenges in their grandparenting, which have thus far been little discussed in research. This paper discusses the narratives of 10 Swedish grandparents whose grandchildren have been exposed to violence towards their mother. The aim was to explore grandparents' narrations of their responses in the face of violence, and their understanding of the role they play in their grandchildren's social networks. Two significant responses are discussed: ‘being there’ and ‘acknowledging the independence and self‐determination of the adult children’. Grandparents experienced these responses as contradictory and felt powerless when it came to their possibilities to protect their grandchildren. The paper suggests that grandparents could be a resource for domestic violence services, and social work practice needs to assess the roles of grandparents of children exposed to domestic violence. Social workers should consider the challenges these grandparents are facing and what support they may need in order to support their grandchildren.
