On March 26, Jen Cardinal posted a video pregnancy announcement on YouTube showing her 14-week old baby clapping in the womb. The video has gone viral, receiving over 100,000 views in less than a week.

While Jen and her husband filmed the ultrasound, the baby started clapping. Jen sang “If You’re Happy and You Know it Clap Your Hands,” and it looked as if the baby was clapping along.

“The experience is one I’ll never forget, the baby clapped three times, then the doctor rewound and scrubbed it while we sang. No mystery. It was amazing,” Jen wrote in the YouTube comments.

This video pregnancy announcement documents a memorable moment for the Cardinal couple, but it also demonstrates the miraculous capabilities of babies in the womb.

A study published in Infant Behavior and Development showed that babies in the womb can begin to recognize nursery rhymes if the mother repeats them between 28 and 34 weeks of pregnancy.

Another study published in Pediatrics Journal found that the more words a early term baby hears in NICU, the more they can respond with their own sounds. Additionally, increased parent speech is linked to higher language and thinking scores when the babies are older.
