We all know that high pitched cry-scream combo that only a baby can make.
As cute as babies are, they can be pretty hard on the ears.
Parents try all sorts of wacky things to get them to stop crying.
One mom discovered the trick. When she plays Taylor Swift's hit "Blank Space," her baby immediately stops crying. Turn it off, though, and she'll start up again.
Watch baby Rosie react to Swifty's voice in the video.
Share this with your friends. Maybe it'll stop them from crying too.
