While the family claims the fetus clapped three times, the American College of Obstetricians and Gynecologists told [TODAY.com](http://www.today.com/parents/ultrasound-video-shows-baby-clapping-mom-sings-if-youre-happy-2D80574882 "undefined") 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. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3763270/ultrasound-fetus-clapping-womb/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3763270/ultrasound-fetus-clapping-womb/"},"headline":"This Fetus Appears to Be Clapping Along to Mom's Singing in the Womb","datePublished":"2015-03-30T15:19:29.000Z","dateModified":"2026-04-13T07:18:10.994Z","description":"Captured during an ultrasound appointment","url":"https://time.com/3763270/ultrasound-fetus-clapping-womb/","keywords":["Newsfeed","Family & Relationships"],"thumbnailUrl":"","author":[{"@type":"Person","name":"Olivia B.
