Once upon a time there was an extremely wealthy couple who was IF. To try and make a baby, they had 20 IVFs. That is not a typo. 20. After 20 failed IVFs, they decided to move to surrogacy. Everything was going fine - but then at 8.5 months - the baby died. Devastating. Was it not meant to be? The couple persevered, and started two more surrogacies at the same time after that. One of the baby girls - born very early - for a while it didn't look good. Were they never to have a baby? But in the end, she was ok. Other girl was born no problem.
So this IF couple was finally happy, they had their almost-twin girls, they resumed life.
And then a few years later....
Pregnant. Naturally. 40 years old. They weren't even trying. Now they also have a healthy son!
And they lived happily ever after.
