A controversial new app has some parents up in arms. 

The mobile app is based off the popular children's movie "Frozen," and allows users to deliver Anna's baby via Cesarean-section.

Sisters Anna and Elsa were children in the movie, but are all grown up in the controversial game. 

"Anna got married and she was pregnant in the spring," the app's description read. "Now nine months had [sic] elapsed, and it's time to give birth to a baby. Anna needs a very experienced doctor to help her deliver her baby. Let's come to help her!"

Users inject Anna with a solution that puts her to sleep, and then use a scalpel to cut her stomach open. After the baby is pulled out, the umbilical cord must be severed. 

Psychotherapist Andrea Nair called the game disturbing. 

"It's potentially harmful to young children," she told Yahoo Parenting. "Cesarean deliveries are typically an emergency room procedure," she said. "You don't want children to expect that that's how babies are always born." 

Nair also expressed concern that children playing the game "aren't old enough to understand what's happening," and "they may even think, 'Cool, I cut someone and a baby comes out.''"

Parents have called for the game to be pulled, but Nair provided a quick solution for those concerned their child may have played "Anna Giving Birth."

"Just tell them, 'Oops, that's not for kids,' and delete it immediately and forget about it — and hope your children do too," she said. 

"Say something like, 'Only doctors cut, and cutting really hurts. It happens in a hospital, and this game is not OK.'"

Parents were also advised to keep their phones and tablets password-protected to minimise their children's exposure to inappropriate materials.
