If I had known there was a song that could calm my son down when he was a bit younger, I'd have played it a lot!
Through lots of experimentation with noises, beats, tempo, and more, scientists engineered this song and determined that it was ideal in making babies happy! They even gave it to some parents to try out for a week, and it worked!
I'm gonna try it out on my (almost) 2 year old tonight.
