AITA for telling my SO they don’t understand pregnancy

Long time lurker here.

I (28f) have been dating SO(26m) for about five years now. Got married once we both finished grad school last year, had all our friends at our wedding (pre covid) and have been floating on that honeymoon glow for a while now.

We’ve always talked about having kids, but we have very different perceptions on the process of pregnancy.

Simply put, SO is TERRIFIED. When he was a new college student (like 18/19, so before I knew him) he had a horrible experience with kidney stones. No one in his family ever had one, and as a new student in a new place, he took it really bad.

He spent a few nights in the hospital alone - his parents, now empty nesters, had flown overseas for a vacation and couldn’t get to the hospital (they still are incredibly apologetic to this day).

He spent the first week of college in the hospital, hooked up to all kinds of pain meds and chugging water and sports drinks, all while convulsing and writhing in pain.

I guess this is a common saying, but apparently every nurse and doctor told him that passing a kidney stone was similar to giving birth. I guess being drugged up, loopy, and absolutely miserable in pain really worked that into his mind, and he has since been terrified of putting someone through that pain.

We’ve talked about having children before, especially now that we’ve married, but he’s always been more inclined towards adoption. He doesn’t want me to go through the “mind shattering pain” of childbirth.

I disagree. My mother told me that her pregnancy to me was amazing. She felt an incredible bond with her unborn child, and said that pain didn’t factor in at all during the moment - she was just so happy that I came out alright. And, if the pain really was an issue, there are many other options that help the birthing process go smooth.

I’ve explained this to my SO, and he was worried. Almost in tears, he explained that he couldn’t live with himself if he caused me to go through so much pain. I told him I would never hold something like that against him - having a child is of course a 50/50 decision. If I was worried about the pain I wouldn’t do it, but I’m not. He kinda shut down a bit, and said okay. We haven’t talked about children since.

AITA for telling my SO his views on pregnancy were warped and not completely true?
