I'm honestly not that old, but when I got married and every wedding I've been to until say, the last decade, it was B&G (sometimes their parents) hosting friends and family while they celebrate joining two families together.
Therefore it would be odd if children weren't invited, little children on the dance floor were.oftenbthe highlight of the day, it would be really strange if the aesthetics.ofnthe day and the photos were more.importnst than the guests enjoying themselves, in day it would have been really odd if anyhhtibg was more important than the guests being comfortable and having fun.
If none of that is important to you, why invite anyone to your special day? Go and have a special day on your own.
