The other night I asked a couple people -- including a stranger -- how much we should pay the babysitter if the kids were asleep the whole time. They all said, "Nothing." WHAT?! I know that's not right, but how much is fair? We usually end up paying between $13-$16 for three kids age 6 and below for between 2-3 hours (they're usually asleep for at least some of it). Is that good? What's fair?
