The song goes: "If you're happy and you know it, clap your hands!"
Which is exactly what this unborn baby did.
When mom, Jen, and her husband noticed their baby clapping in an ultrasound, they decided to sync the clap-like movements with the cleverly picked song.
Watch the hilarity unfold below:
In 2013, The Washington Post quotes Eino Partanen, a University of Helsinki psychologist, who says, "The voice of the mother is the most salient sound in the womb." According to Partanen, the sound is transmitted through the bones and can be more effective than recorded music.
So hopefully this happy song is one the baby will remember.
