Gender reveal

[HearingMyOwnVoice]

I saw a video of an acquaintances gender reveal today. She has an older son and three daughters. The paper gun thing went off to reveal she was expecting another girl. Everyone groaned.
I know this is one of those things that is completely divisive and I'm completely for anyone's choice to be respected.
I have two children of the same gender who are close together in age. We had another five years ago. We didn't find out the sex. I'd assumed that they would be the same as their siblings. They weren't. We were happy but not because they were a different sex to their siblings. I struggled a bit at first tbh as I was expecting the opposite.
Anyway to get to my point part of my reason for not finding out was seeing kids end up so sad at gender reveals when it wasn't what they wanted. I reasoned that when the baby arrived and they met him/her that they would be so caught up in excitement that they wouldn't really care what the baby was.
Is the chance to find out the gender worth the upset and disappointment that some kids feel for months after they find out?
Completely expecting to be flamed for this but I'm genuinely intrigued by it.

The worst thing wouldn't be the 4 children who were there watching it a few years later. The worst thing would be the baby girl who is yet to be born watching it many years later and thinking so that's why they don't like me. I know adult who were told as children that their sex was a disappointment to their parents or grandparents and it still hurts. I think sending round robin Christmas letter mentioning how disappointed you were to have a second girl or whatever is also pretty callous. The chance of a copy being tucked away in a box by doting great auntie and found when clearing out her stuff is quite high.

And everyone groaning? the parents as well? That is going to hurt that little girl so much. It is so sad when you think how many people would so love a baby regardless of it reproductive system.
