This baby nearly jumped out of her skin when she heard a pig grunting sound come out of nowhere.

In the video, Tierney-Rose is seen being cradled by her mother when she suddenly hears a strange sound. Her eyes widen in shock as she looks at her mother.

The mother told Newsflare that she and her sister had the idea to scare Tierney-Rose. Her sister hid behind a sofa, away from the baby's view, where she then emitted the strange sound.

"Me and Holly couldn't help but break into laughter," she said.
