Maybe dangerous for a natural birth...but a c-section is certain.
C-section?
Not necessarily.
My mother turned 14 three weeks after I was born and didn’t have a c-section.
Now I don’t know how big? Physically Mom was at the time but Mom has never been above 4’11” and 95-100 lbs.
So I’d guess she was a typically small little girl at 13.
My dad was 17 and yes, my parents raised my brother and I until we were grown.
(Helped by dad’s parent’s until he joined the service a year later.
And after boot camp.)
