I know someone who is pregnant at almost 50 with her first baby. I didn't ask if it was natural or not (none of my business) but she did tell me she was still getting menstrual cycles. I know a few other women in their 40's who are pregnant. I am 39 but hope in a few years to have a child if things work the way I want. The guy I like even talked to me about us eventually having a child (and marrying) but this is at least 2 years away or more, which will put me in early 40's.
Anyway, I was talking to a mutual friend about all these other women (she knows them too) and she mentioned "oh they are all having change of life babies". At first I didn't give it much thought but then I thought it was rude because they aren't going through menopause so how could it be change of life babies?
Late babies run in my family too and all of my great grandmothers had babies late, in fact a few had babies when they were already grandmothers! In this way I understand the term because they were going into a change (change here being a grandma), but not the others. Unlike in the past, these were all planned pregnancies by women who realize their time of getting pregnant is coming to an end.
