One of my families is like this. They "definitely" and "would be nice" want kids. Thankfully they had one, but each time after that they would refuse or argue. I pampered them so much to make sure they'd be in good moods, and have plenty of food, money, and even a bunch of house upgrades... but no! Baby boosters, etc, nothing worked. So I'm thankful they managed to have at least one. They were supposed to be my Middle-Class-working-huge-family Family!
I also have one family who don't want kids, and they ended up with four! They had one on their own, and then adopted three more. Hah.
... Then I have my free spirited yoga family who had triplets and then two more singles.
Anyway I think the adoption is supposed to be the failsafe? Kids randomly show up on their doorstep and you can adopt them. But my family who didn't want kids are the only ones so far to have them.
I have three separate families just to make sure everything goes alright and I have "backups" just in case, so things don't happen like what happened to your family.
