So my guest list is up to about 150 people, and I expect about 80 to come, however there are two very important people who I'd like to be there who will have infants. Both of them are out of town, and I DO NOT WANT ANYBODY THERE UNDER 18. I am COMPLETELY fine with them not attending, if it means they HAVE to bring their newborn.
I understand that is unreasonable to want someone to leave an infant at home with a stranger/relative at that age especially OOT. How do I specify on my invitations that I'd prefer they decline than bring their infant, either on a two hour car ride or a cross country flight? I love these people very much and will more than likely be visiting them after the wedding to meet their new children.
