Chelsea-based company Arklu is the toymaker behind the doll. They've been inundated with requests to create a pregnant version of their already best-selling Duchess of Cambridge.
Despite the potential volume of requests, the company may want to consider that pregnant dolls haven't gone over well. In 2002, Mattell released a pregnant version of Barbie's friend Midge (at the time, her bio included a marriage to a man named Alan and a firstborn son named Ryan). But Wal-Mart pulled the doll after customers complained that it was too real for their little girls (Midge had a magnetic removable stomach with a baby in fetal position inside. TMI, said parents.)
The company told The Huffington Post that there are no current plans to create such a doll, despite customer demand.
