Final answer:
Children are more likely to have grandparents in their lives due to changes in family structures, societal changes, and recognition of intergenerational relationships.
Step-by-step explanation:
There are several reasons why children are more likely to have grandparents as part of their lives today than in the past. Firstly, changes in family structures, such as single-parent households and nontraditional families, have led to an increased role for grandparents in childcare.
Secondly, societal changes, like increased life expectancy and improved healthcare, have allowed grandparents to be more active and involved in their grandchildren's lives. Lastly, there is a growing recognition of the importance of intergenerational relationships and the positive impact they have on children's development.
