This song works wonders on a fussy Harper. Anytime she is crying or upset for any reason, Grace can sing this song to her, and instantly she stops crying. Works every time. The kicker is that she has to continue singing the song over and over because as soon as she stops, Harper starts crying again. It's kind of funny.
Here is the song... Grace is practicing her Soprano (I think... I know nothing about music...anyways, she's singing in the high notes...)
