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.

Me and my sister (named holly) decided it would be fun to make a video of my daughters (named Tierney-Rose) first scare. Holly hide in the kitchen and crawled into the living room slowly and quietly hide behind the side arm of the sofa she jumped up making the first sound that came out of her month. A pig grunting sound, Tierney-Rose was relaxing having cuddles with me when she was startled by the sound, she looked at me to say what the heck was that. Me and holly couldn't help but break into laughter. Tierney-Rose looked to me in shock as to say whats so funny.
