I think the point is that boomers are now 60 to 80, and some of their their children are reaching their 40s without yet having kids, and the boomers are finally realizing it isn't gonna happen.

The "prime grandparenting age" part is just headline fluff.

According to Pew, 85% of Gen X women have had at least one child. This is just boomer doomism.

44 to 60 thank you. I aint no goddam millennial.
