Wonderful write-up,seems we are in the same page because this trend is not my thing considering the evil people do. There's one thing I want to point out l.

What if after having party and revealing the gender of your baby and when the baby finally comes, the gender changed?

If gender is properly revealed nothing changes it ,unless it's wrongly revealed. That's why every pregnant woman should use good hospital with sound machines and qualified doctors. If you talk about miscarriage then I will agree 💯 percent.
Anyways I say no to this trend. Cheers .
