Why should I not have 1 child when you have 4 or 5? Wouldn't it be better for us to have 2 each? It is only overcrowded because of families like yours. I'm not the one that needs to make the changes.
LOL @Wolfgirrl.
You're not keeping up with demographic trends, are you?
Despite the best efforts of parents having larger than average families, the UK fertility rate was 1.7 children per woman in 2018.
In developed countries, the sub-replacement rate for the population is a fertility rate of under 2.1 children per woman. In order for the population to increase through births and for the environment to be totally and completely swimming in disposable nappies, each woman in the UK would have to apply herself considerably to the production of more than 2.1 babies.
For every woman having five babies, more than 2 woman have none at all. Two women, remainder one leg, perhaps. I've never been any good at division in my head.
Whatever about the finer points of the maths, it's clear there is no need to fret.
Enjoy a nice cuppa and chill.
