babies like to hear people slurp wine

Based on this video from Japan, apparently babies are curious and will stop crying with the sound of the slurping noise that wine drinkers make to aerate the wine in their mouth. In the video it makes it look like the babies stop crying all together. Too bad they don't continue to show it for a few more seconds later when they get bored of the new sound and start crying again.

Oh well, I'm going to have to try this the next time we go babysit the nieces.
