The window for great-grandmothers is closing

The linked article is about the declining trend of having great-grandparents due to people having children at a later age. The author notes how their grandmother became a great-grandmother at an earlier age than their parents likely will, and how the trend of having children at later ages will inevitably lead to fewer and fewer great-grandparents. The author reflects on the historical context and the potential loss to society as a result.
