For us it did. We wanted to make sure we were financially stable before having our own kids. My hubby already has four children and neither of us wanted them to go without just so we could have a baby. To me it wouldn't have been very fair on them. I don't think there is anything wrong with people getting by on little money if they can make it work. As long as people have enough to provide NEEDS, if you put that with love, happiness and a stable environment and that's all you need.
My parents are proof of that - Dad came from nothing and was one of 4. Mum came from a comfortable lifestyle and was also one of 4. Dad went to public school, went without pretty much everything growing up, hand me downs, shared bedroom etc etc but he turned into a wonderful, amazing, loving father and husband. He had a great career and lived a happy life and was able to provide us with a wonderful life. Mum went to private school, was the first in her street with a colour TV, went on family trips all the time, had a family nice car etc etc and she also turned out to a be a wonderful, amazing wife and mother with a great career. They came from completely different financial backgrounds but both had parents who loved them and created a happy home.
Having a baby is a costly experience for us (IVF and another operation) so we needed to make sure we had enough saved before we started trying.
We both earn a very good combined salary which helps but we still waited until we knew we would have enough so that the other kids didn't suddenly start missing out. Which for both of us was very important that they didn’t feel they were suddenly second best because of a new baby.
But at the end of the day it doesn't matter how much money we have - no amount of money means you can actually have children For some people it's not as easy as just saying "yep lets have another baby". Some people struggle to have just one and that has nothing at all to do with money.....
