A recent study suggests that physically healthier grandmothers may actually spend less time babysitting their grandchildren than those with poorer health, challenging what many people might expect. The research, led by Athena C. Y. Chan, PhD, analyzed data from the U.S. Health and Retirement Study, tracking over 5,500 heterosexual couples aged 50 and older who had at least one grandchild between 2010 and 2016. Researchers aimed to understand how grandparents’ health influences caregiving patterns within families.

Interestingly, the findings showed a consistent trend: grandmothers who reported better physical health were less likely to take on regular childcare duties. In turn, their partners—grandfathers—also tended to spend less time babysitting. This pattern stood out because it contrasts with the assumption that better health naturally leads to more caregiving ability and involvement.

Researchers suggest one possible explanation is that healthier older adults often have more freedom and options for how they spend their time. Instead of being primarily available for childcare, they may choose to work longer, travel, socialize, or pursue personal hobbies. Meanwhile, grandparents with limited mobility or fewer outside activities may naturally spend more time at home, making them more available to help with grandchildren.

Overall, experts emphasize that staying active remains highly beneficial in later life, supporting both physical and mental health. Whether it’s walking, gardening, or joining fitness activities, movement helps older adults maintain independence and well-being. And while grandparent childcare remains valuable, balancing family support with personal health and lifestyle choices can benefit everyone in the long run.
