My fiancé and I got engaged in June 2020 and have really only recently been finalizing our guest list. We have decided to have a kid free wedding but he has assumed that our 2 nephews (both under 3) and niece/nephew on the way (who will be one month old at our wedding) are the exceptions. By the time of our wedding in November 21 the oldest nephew will be 3 - and I agree would make a cute ring bearer but I don’t want his infant sibling at our wedding. My other sister in law has a one year old baby and I think that is too young for our otherwise adult only event. How do I tell my two sister in laws that I don’t want their kids at our wedding?
