When I do the math, one particular consequence of having children later in life hits me squarely in the face.
I had my first daughter at 39. If she has kids when she's older like I did -- let's say she gives birth the same age I was -- I will be a whopping 78 when I become a grandmother. 78!
Will I be able to be the Nana I hope to be, have close relationships with my grandchildren and watch them so my daughters can devote more time to their careers, or will my girls need to be taking care of me in addition to their own children?
