This Fetus Appears to Be Clapping Along to Mom’s Singing in the Womb

YouTube user “Jen Cardinal” uploaded an ultrasound that appears to show a fetus clapping as the doctor and the baby’s family sing “If you’re happy and you know it, clap your hands.” The video has racked up more than 2.4 million views and questions about whether a fetus could really do that.

While the family claims the fetus clapped three times, the American College of Obstetricians and Gynecologists told TODAY.com in a statement that a fetus could unknowingly make movements that look like that, and if it did clap, then it is possible that it happened once and the video was edited to look like it happened over and over again.
