Over one-fifth of children of below school age in Australia are currently cared for by their grandparents as part of regular child care arrangements. How do grandparents view this role? Insights into grandparents' experiences have the potential to inform child and family policies. Following a short outline of previous grandparenting research, this article draws on data from the recent Grandcaring Study, which sought to gather the perspectives of grandparents on their role as (informal) carers of grandchildren on a regular basis, and to identify the joys, frustrations and dilemmas associated with that experience. Underlying its experiential orientation, the study was also open to investigating the sensitivities of relationships between grandparents and their grandchildren and between grandparents and their adult children who were the parents of the grandchildren.
