My mother had her first c-section 28 years ago, her 8th 16 years ago. I think Mrs. Duggar’s ovaries will give out before her uterus does.
I’m surprised her womb hasn’t collapsed from so much use. I had a cousin who had 4 babies in 4 years and she almost lost the 4th one because her uterus was weakening. I realize that all of our bodies are different, I would think that somewhere around the 13th or 14th child, her body would start rebelling. I guess not.
