While this woman and her husband were going in for their 14-week ultrasound, they noticed their baby was doing something out of the ordinary. Believe it or not, the unborn baby appeared to be clapping inside the womb. The doctor suggested they should film the unique moment. So dad pulled out his cellphone and started recording. Then, to make it even more fun, mom started singing “If you’re Happy and You Know It.” Well, I guess it’s pretty reassuring to know your unborn baby is happy inside the womb and he/she knows it. Now clap your hands!
