I've only been to one wedding that was "Adults Only", and actually, it wasn't really, but they didn't want really young children there in case they cried/caused a scene during the ceremony. Maybe it's a regional thing, or maybe it's just not the norm in my circle? The Adults Only reception seems to be pretty common on this and other boards I've visited. Personally, I have no problem with kids and one of the things I'm most looking forward to is watching the young ones play and have a good time, because I have many great memories of family weddings from when I was a kid. What is your plan for including/not including kids at your wedding?
