When they had 12 children, husband was working down the mines 16 hours a day, no transportation, no frozen/canned food, no fridge, constantly pregnant. No help if somebody suffered a disability (and I think this was likely working down the mines those days).
I just wondered because I have far less then 12 children and dh does not work down the mines and still we are often soooooo tired. Children keeping us awake play a role in this... how would we cope if there was 12 of them and we had to live under the conditions described above?
