A select few family members kids are invited to our wedding. The only reason any kids are invited is because my fiancé has a niece...meaning flower girl. The other kids invited are immediate family - all of like 6 kids. A second cousin and his wife were invited. The invite had JUST "Mr. and Mrs.______ ______" They RSVP'd for 5 including their 3 young children. My mom is telling me not to say anything because they're family, but we really want as few kids there as possible. I can't use the reason "no kids at all" because a handful of kids are invited. Do I still say something or just let it go?
RSVPs are still coming in so we also don't know how many others aren't going to practice invitation etiquette.
