I do wish there were some way (other than personal responsibility!
) to insure that those who don't want children don't have them, and those that do can do so without undue hardship.
We were married for 20+ years before having our one and only son. As my wife approached 40YO it became evident it wasn't "just going to happen" and we deeply desired to have a child. This was not a case of "Oops, an accident". No one was ever able to diagnose the problem which is how we ended up doing the Full Monty of IVF+ICSI.
And it was so totally worth it. Our son is truly one of the finest humans we know, and that's not just a proud Dad talking. As an infant he showed some signs of what I interpreted as potential autism but I specifically worked with him as a baby to avoid that and now, at 19YO, he is perfect in every way. A competitive swimmer (so no physical issues), in his junior year of his BSEE degree (so no mental issues), can play in a crowd but also study alone, an internationally ranked drone racing pilot that's been on TeamUSA at the World Cup two different years, etc.
I understand your comments about "went to lengths to make it happen and he ended up with severely autistic twins". I was frankly terrified of "pushing too hard" and overriding nature with technology. But as a result I kept a close eye on his early development and actively managed what I perceived to be risk factors. I don't know if other people pay attention like that, or if any of it mattered at all, but here he is and things couldn't be more perfect.
Well, OK, they could be more perfect in the sense that we wanted more children and went the IVF route a couple more times but it never worked again. Amazing odds BTW... they say you have a 30% chance of carrying to term for each attempt so "don't get your hopes up on the first couple of attempts". Yet after everything else had failed, IVF worked perfectly the very first time - and then never again.
We cherish our son and are thankful for every single day with him. He's soon off to school again and has openly told us that while he'll come home for visits, he likely won't be home "to live" again due to internships and other opportunities. Emotionally we hate it, but we recognize this is exactly how his life should be progressing. Parenthood isn't for everyone and we respect that, but it's been the single best thing to ever happen in our lives.
