I used to play this song to Billie a lot when she was in my belly. I was putting the headphones directly on my belly and would play music to her. For some reason, I was really into this specific song at the time, so she heard it for sure a lot during her 9 months in there.
After she was born, everytime she was crying a lot and seemed in panic, I used to play her this song and it worked, it was calming her down. I don't know if she remembered the song but it made me very emotional to see the effect it had on her.
