If you're a parent of young kids, you know sometimes you'll do anything to get them to stop crying! Well, put this in the "anything" category.

Child psychologists at the University of London recently hired Grammy-winning singer Imogen Heap to help create the perfect song to make babies happy.

They used a test group of babies and monitored their heart rates and body language while they played different songs and melodies until they found the sounds the babies liked most.

Examples.... the word "boo," the sound of a dog barking, and other babies laughing.

The babies wanted 163 beats per min for their happy song, and they liked a woman's voice better.

 

Here ya go... it's the first song that's been scientifically engineered to make babies happy.
