The youngest child of a family, usually with a large age gap between that child and the next youngest. Generally a product of a mom who had the kid in their 40s or later.
I had my first three kids in my 20s. I thought I had entered menopause when I turned 40 as I stopped having my period. But it turns out I was pregnant with my "oops baby."
