The aim of this study was to describe experiences of peer support among mothers of children with congenital heart defects. Ten mothers were interviewed through a semi-structured approach and interviews were analyzed with systematic text condensation. The respondents established various channels used for peer support and navigated between the channels depending on what type of information or support they needed. Through the channels, they found peers they developed strong friendships with and who they relied on for emotional support. Communicating with peers involved the reciprocal exchange of unique emotional support between peers who understand each other as well as the exchange of information derived from their collective knowledge, and thus, difficult to find without the help of peers. The findings illustrate the potential strengths of establishing reliable collaboration and liaisons between clinical units and peer support networks.
