For the most part, you're not likely to find a new parent who would say that they love it when their babies cry.
At best, they might think it's a useful indicator that they need to do something but it's a sound that definitely serves as the soundtrack to parental stress, particularly when it happens during the night.
However, there's on exception to this rule that can make a baby's cries almost seem like the most beautiful sound in the world. For my dad, this was when we were in a serious car accident that he wasn't sure I had survived until I wailed.
And for one Louisiana couple, that sound was their beacon of hope when their infant son ended up in a similarly life-threatening situation.
