My grandmother had five children. She had her first at the at the age of 23 and gave birth to her last,in 1954, at the age of 47.
No IVF involved.
I had my first child at 24 and my 10th at 45, simply by the natural operations of biology.
Yep! I knew many women in their mid-50’s with biological children under 10 (and sometimes children in their 20’s and 30’s at the same time).
Most women my age didn’t marry until 30-ish, and they still had children easily through their 30’s, early 40’s, and sometimes late 40’s without planning to.
You put my Grandma to shame!!
My biological mother had me at 15 and my youngest sister at 42.
