Baby sitters and au pairs about ten years ago got a lot of bad publicity about having injured their charges.
I am reminded of overhearing a couple of homeward bound baby sitters on a bus in outskirts of Boston. One was complaining bitterly about her charges having made so much noise she couldn't enjoy her rock and roll tapes. Her companion said smugly: I don't have that problem. I turn on the gas in the oven and shove their heads in until they shut up."
