When parents Shaun and Heidi Guerard wanted to surprise their daughters, Giuliana and Grace, with the gender of their yet-to-be-born baby, they had no idea how the young girls would react.
In an adorable YouTube video posted by their mother, the sisters were given cupcakes and told to break them open. If the inside was pink, then the family was having another daughter, but if the cupcake was blue, the family would be welcoming a baby boy.
Giuliana, 7, opened the cupcake revealing blue on the inside, much to her delight. Grace, 3, was not as excited to have a future baby brother.
The video was posted last year but recently went viral because of National Sibling Day.
Their brother, Grant, was born in October, and according to their mom, he is loved by his sisters.
"They're like little mommies," Heidi Guerard told ABC News. "They look out for him."
