Maybe, my own children have had problems, though. I got married at 21 (DH was 25) but my kids got married at 28. waiting to have a child was not what they hoped. Maybe just the waiting is what’s doing it but they were the same age I was when I had my second child.
The wait will do it. My wife and I waited too long and ended up adopting. We did all the testing and could have gone the hi-tech route, but that’s expensive with no guarantees, and meanwhile kids are sitting in orphanages waiting for homes. It was the right choice for us.
