I'm having a medium-sized wedding (about 75 people). It's something of a destination in Orange County CA, where the groom grew up, and most of the guests will be traveling in from out of town. There are two children of family I'd like to invite, one is 8 and one is in middle school, but otherwise I'd like to exclude kids from the event. I have some family with infants and small toddlers and while I love them all and would happily invite everyone if I were throwing a much larger wedding, I just think it will be a more enjoyable event and easier to keep the guest count where we want it if young children and infants are not invited. It seems tricky to explicitly say kids are not invited but then have a couple of exceptions, so my question is if it's appropriate to indicate that we are not inviting any children under the age of 7. Is creating an age cutoff like that helpful or inviting hurt feelings?
