The family represents the cause of as well as the solution to childhood overweight in many family-based childhood weight management interventions. Involving the family also entails involving the individual family members’ experiences with, attitudes towards, and understandings of obesity. This study explores how families with life-long experiences of overweight manage and experience a family-based childhood weight management intervention in Northern Zealand in Denmark. The analysis is focused on family narratives and their temporal character. The families’ narratives about overweight and past weight management interventions are crucial to how they understand and manage the present intervention. Additionally, the families expect the focus on weight management to continue to be a constant part of their everyday life. The paper concludes that the understanding of weight management in interventions should take its point of departure in the life-world, which the individual family creates through members’ narratives about overweight.
