Look, a baby sleeping with a butcher knife. Awww, how cute! Milwaukee's public-health unit and local agency Serve Marketing produced these controversial ads to warn parents about the dangers of co-sleeping with their infants. Wags might suggest it's not that dangerous, then, since most babies don't know how to use knives. Frankly, if the spitty, squealing brat hasn't had its baba yet, I'm not willing to take that chance. Joking, of course. It's a serious issue, and emotions run high on both sides of the debate.
