My sister-in-law comes from a family with 17 kids. The mom lost two at birth so she has actually produced 19 children. But since there were 2 sets of twins I guess she has only been pregnant 17 times (!!) I'm always fascinated with her family and asking all sorts of questions... like how do you all live in one house. She says, actually, we have 2 houses, one is across the street omg, I can't even imagine. But yes, the older ones provide a lot of care to the younger ones, and the older ones also grow up and move away from home, so there isn't everyone living under one roof (or 2 in this case) at once.
I was always just amazed and had to meet this woman, who's body had produced 19 children! Think of the biomass alone! I thought she would be the most tired looking person I ever met. I was even more amazed when I did meet her, a petite bubbly woman with TONS of energy! And lots of fashion, she always wears a big fashionable hat, reminds me of some long ago time when women wore hats a lot.
