Tennessee mum pulls a brutal 'switcheroo' prank on husband during barbecue

A mom has sparked a fierce parenting debate after she pulled a brutal prank on her husband.Mariah Miller, 29, from Tennessee , decided to test her partner, Alex, 34, to see how well he knew their 10-month-old daughter, Belle, and it went incredibly wrong.She and her best friend Joy noticed their daughters look a lot alike, so they decided to switch them and see how long it took Alex to notice.During a recent barbecue, Mariah handed Joy's daughter, Elsie, to Alex pretending it was their own daughter.Despite looking at her face multiple times, fixing her hair, and giving her a kiss, Alex did not realize that the baby he was holding was not his own offspring.It wasn't until Mariah brought their actual daughter out that he made the realization that he had been playing with an entirely different child the whole time.
