There were reasons for having kids and also lot more kids in the past; death or chronic illness of some of them, needing kids to take care of the elderly and work the lands and, the one many forget; religion nonsense as in not being allowed sex if not for reproduction. In the village where I was raised, all families had kids until the wife cannot have them anymore or dies because of that. And because of the rapid decline of religion over there, it was pretty much inbreeding as there are not many candidates that want a life like that outside these families, so always some of them have massive defects (my neighbour had a son born without a left arm, a blind daughter, a son with a disabling low iq, and more like that).
