A Grammy award-winning singer has become the first singer to release a song that is scientifically proven to make your baby smile.

鈥楾he Happy Song鈥� is a two-and-a-half minute long jingle, with lyrics about the sky, the sea and animals.

5 live鈥檚 Michelle Dignan tested it on her four-month-old baby 鈥� you can see the result in the picture!

It was created by C&G Baby Club and Felt Music, based on the research of Goldsmith University Psychologists, Professor鈥檚 Lauren Stewart and Caspar Addyman, who spoke to 5 live.

He said the song contains different elements that appeal to babies, such as a 鈥渇emale voice 鈥� babies love a female voice 鈥� and had to be in a major key鈥�.

Along with Stewart, Addyman played four melodies to a group of babies and said there was a 鈥渃lear preference鈥� for 鈥楾he Happy Song鈥�.
