Ain't really your call.

But even ignoring that, I tend to agree with them on the no kids policy. Kids take over weddings, the dance floor, etc. They distract from the party atmosphere IMO. So I've always preferred kidless weddings, just on a personal level. But obviously I understand the hardship it can create for you and others, so I get where you're coming from.

But again - not your wedding, not your place to dictate.
