The prospect of a new addition to the family thrills some people – but may be hard to swallow for others.
This was certainly the case when Tiffany McCall decided to reveal her pregnancy to her daughter, Braylee.
In a video filmed in their home in Anderson, South Carolina, the five-year-old empties out a gift bag to find some clothes and a picture of an ultrasound scan.
"You're gonna be a big sister," says McCall.
But Braylee doesn't take the news well.
Sending a darting look between McCall and her off-screen husband, Landon, Braylee insists: "You're just kidding!"
When it all becomes clear that it is not a joke, Braylee rips up the photo and discards it in disgust.
McCall told Newsflare: "She also wants a brother and she's adamant about being upset if we have a girl.
"Should be interesting to see the reveal!"
The clip was filmed on June 20.
