[WATCH] This Astonishing Ultrasound Video Proves That Unborn Babies Just Want to Have Fun

Researchers say that babies as young as one or two days old have a definite sense of rhythm and they can detect changes in a musical beat, even when they’re sleeping.

But Baby Cardinal, an obvious overachiever at only 14-weeks gestation, was caught on ultrasound clapping along to music in his mother’s womb!

His mother, Jen Cardinal, wrote in a note accompanying the amazing video she posted on YouTube, “At our 14 week ultrasound our baby was clapping, so I sang a song with our doctor as my husband filmed.”

In the ultrasound video you can clearly see the tiny baby clapping his (or her?) hands together as his parents sing “If You’re Happy and You Know It Clap Your Hands.”

Amazing that he’s able to do this just 3 1/2 months after he was conceived!
