Health issues aside, there is another problem with advanced maternal age that I almost never hear anyone mention, but one that worries me with things trending the way they are, and with which I am intimately familiar: the older a woman is when she has a child, the younger that child will be when they lose their mother.
I was born when my mother was in her early 40's. She died when I was 20. Even if she had made it to the respectable age of 70 or 75, I would still have been a young woman when my mother died. My brother, on the other hand -- 17 years my senior -- had almost 40 years with her.
I came as a surprise, and I don't fault my mother for choosing to bring me into the world, but I know she would not have become pregnant intentionally at that age and I can't help but question the wisdom of those who do it now. They're subjecting their children to a very wide generation gap -- which believe me, can be a big problem -- and depriving them of who knows how many years spent with a young, energetic, healthy parent.
I feel terrible for the babies I've heard of who have been born to women as old as their sixties, at least one of whom died just two or three years later. How many such infants, in addition to lifelong health risks and problems these late births may saddle them with, will never even get to know their moms before they lose them?
