What's a nice way to say "make your kids behave"?

It's an outdoor wedding, so no separate rooms. I put in another post above that I'm realizing I really don't want to "kid orient" my wedding...were not having yard games, or anything like that, though I would be fine with kids having their own little games/coloring at the tables...but our friends and family are going to be drinking, having fun, not thinking about the kids there, and it just seems like such a pain to me to have to worry about what the kids are doing...also I don't know most of these kids. Even FH hasn't met most of them. So the unknown is a little rough. This thread has made me realize that I really don't want kids there, and will be talking to his mom today about it.
