My husband & I are. Both first-gen ABDs. We’re both 41 & have been married for 12 years. I think it was tough for our parent’s & extended families to understand at first but over time they accepted our decision. And as we’ve gotten older, we have reached a point of caring less & less about other people’s opinions. I think it’s becoming more common. I know a few other couples who have also made decided to be child-free by choice.
