If you look at mortality birth rates before medicine, you will see the population did not grow as quickly.<quoted text>
No one in my immediate family needed any medical assistance at all to get pregnant or keep their children alive until birth. So I'm not sure why you are saying this. As I have a huge family, you saying "most" should have affected my family by probability.
You are suggesting that without medical assistance, children would rarely be born. How do you explain the population of the earth up until the modern medical age? You are making some very off the wall assumptions that have thousands of years of evidence that you are wrong.
And this isn't even relevant. If a child isn't born because of natural causes, it has nothing to do with forcefully stopping a child from being born. You are making it sound like people are creating life in a Petrie dish and then pouring bleach on it when the bell rings at the end of class.
But many people back then had multiple babies due to the mortality rate. Many if not most had, or tried to have several children. Most always, some died.
