Only a cold-hearted soul would ignore the sad pleas of a crying baby. But those who’ve heard this urban legend might think twice about opening their front door if they hear a baby crying. According to the tale, a would-be criminal puts a recording of a wailing infant on your porch and hides nearby. When you open the door to check on the distressed tot, he suddenly attacks. In another version of the story, a recording of a mewling kitten or whimpering puppy is used to lure you out of your house. Or they might place a baby carrier beside a deserted road while they lurk nearby, hoping you will stop.
