I'm going to ask my fiance's maid of honor to not bring her son to our wedding
Why don't you want her son at the wedding?
I cannot stand children. Their noise stresses me out.
You should allow your important guests to bring their family members to a wedding. Maybe you can create a separate area for the children if they're too loud. That way the children won't disturb other guests.
No, it is my wedding, my rules.
Guests might need to bring their kids because they cant find someone to watch them. If you ask them to keep them at home you might lose a large part of your wedding party.
