Intergenerational family ties include relationships between grandparents and their grandchildren. Historically, scholars have examined intergenerational solidarity including the influences of contact, comfort, geographical proximity, beliefs, and values within the grandparent–grandchild relationship. In the early 21st century these issues are still important; however, scholars have become more interested in contemporary intersections between individuals and families, leading to advancing the understanding of the grandparent–grandchild relationship. Researchers have found that grandchildren provide care‐related tasks for grandparents when the latter are frail or sick. Further, regardless of sexual orientation of grandparents and/or grandchildren, close ties remain. Grandparents also continue to assume parenting roles to grandchildren as custodial grandparents. Issues related to grandparent–grandchild relations are likely to receive greater attention as the number of older adults who experience grandparenthood continues to increase.
