Reasons for low fertility rates and the wokeism cancer

Shugard

I think in the end it on the female to decide how many kids to have. People can change too. I never wanted to have kids. I may have been in a similar mind set to your friend. Lucky I woke up!

BTW where I live in semi rural Western Australia it's not uncommon to meet families who have 4-5 kids. I think it also comes down to happiness and stress. If you're enjoying life, you naturally want to have more. Unfortunately for us, we started pretty late and it looks like its going to be 2 kids. We'll see, you never know!

Good luck!
