The present-day involvement of men in many facets of childrearing stands in contrast to previous eras when men accepted that the major task of fathering was to provide a secure income to support the family. This imperative often required long hours away from the family. However, when men whose contact with children has been limited due to work and cultural constraints retire, their newly acquired lifestyle may bring fresh opportunities for involvement with grandchildren. An important question therefore concerns the impact of caring for young children on men's perceptions of their role as grandfathers. This interview study explores the experiences of 19 Australian grandfathers. The analysis found themes that relate to relationships and change, as well as themes concerning core beliefs and existential questions. The findings demonstrate the potential for insight into family relationships and personal growth in older age when studying the topic of grandparenting and caring from the male perspective.
