LOL!
When I was a new bride, I spent two weeks at my husband's uncle's farm, taking care of his kids while his wife was in the hospital having her 10th. All of them were under the age of 13.
I had never seen such hugh pans, nor cooked such hugh quantities of food in my entire life! I did it, though. And I washed all the dishes as well as all the clothes.
Whew!
But I left there, still convinced I wanted a dozen kids....
I assume the lady didn't breastfeed. I couldn't have kids that fast if I wanted to, unless I had multiples.
