At 67, with no husband, and planning to continue full-time work, perhaps she should just accept that she's not in a good situation to be a first-time mother, through birth or adoption.
That is probably true, and a more accurate representation of the very difficult choice that she faced.
I just wanted to correct the misrepresentation that her choice was between giving birth and adoption. Her options were more difficult than that, and I have sympathy for her, and the child.
One does wonder why she didn't do something about any of this earlier. She may indeed be not in her right mind.
