How do you deal with a guest's rambunctious child?

"Many experts say to talk to the parent, but I would approach the child first. Say something like 'Hey, Junior, that's not a toy, and we need to put that back.' I think most parents would be grateful not to have to say 'Stop that!' for the eight-billionth time. (I know people who say, 'I would never let someone else reprimand my kid,' and that's why their kids are nightmares.) I'd give a child two chances. If he does it a third time, address the parents and say, 'You know, this is kind of getting out of hand for me.'"
