Parent–child reminiscing conversations in early childhood have received theoretical attention as a forum for children's self‐concept development, but this has been little addressed in empirical work. This study examines associations between emotion reminiscing and children's self‐concepts and, building from the reminiscing and personality development literatures, also explores the role of children's coping. Sixty 4‐ and 5‐year‐old children and their mothers completed reminiscing conversations about events in which the child had experienced negative emotion, children completed an age‐appropriate assessment of their self‐concept, and mothers and teachers reported on children's coping strategies. Children's self‐perceived timidity was associated with their explanations for negative emotions during reminiscing. Children's self‐perceived negative affect was associated with fewer emotion resolutions during reminiscing, and with distinctive patterns of coping. Both reminiscing and coping made unique contributions to children's self‐concepts, and findings also suggest that coping may in some contexts indirectly connect reminiscing with self‐concept. These findings suggest that reminiscing conversations both reflect children's characteristics and provide a context for learning about their characteristics, along with strategies for emotion management.
