More than 30 years ago, Elder theorised multiple life-course trajectories in domains such as family and work, punctuated by transitions that create the structure and rhythm of individual lives. We argue that in the context of population ageing, family care should be added as a life-course domain. We conceptualise life courses of family care with core elements of 'care as doing' and 'care as being in relationship', creating hypothetical family care trajectories to illustrate the diversity of life-course patterns of care.
