Catherine, Duchess of Cambridge, has expressed a wish to have "more babies" with her husband Prince William.
The royal couple, both 35, already have three-year-old Prince George and two-year-old Princess Charlotte together, but it seems the brunette beauty still wants to expand her brood.
Catherine made the lighthearted comment during her trip to Warsaw, Poland, on Monday when she was given a cuddly toy designed to soothe tiny babies during a visit to an event for start-up tech companies.
Upon receiving the gift, Catherine told her husband: "We will just have to have more babies."
The soft toys, from company Whisbear, are designed to comfort newborns by replicating the sound of the womb, responding to their cries to soothe them.
Julia Sielicka-Jastrzebska, who founded the company with her sister, said after giving the gifts to the Duchess that the beauty admired the bears, but noted they were made for children younger than George and Charlotte.
Julia said: "We gave the Duchess some presents for Prince George and Princess Charlotte. She said they should have more babies, and they laughed."
Prince William and Duchess Catherine are currently on a five-day tour of Poland at the request of the Foreign and Commonwealth Office, as part of an effort to maintain good relations with European countries despite Britain's impending exit from the European Union, and have brought their brood along on the trip.
A Kensington Palace spokesman explained prior to their trip that the Duke and Duchess are excited to be travelling with their children.
The spokesperson said: "The Duke and Duchess are very much looking forward to this tour and are delighted with the exciting and varied programme that has been put together for it.
"They have decided that their children, Prince George and Princess Charlotte, will travel with them and we expect the children to be seen on at least a couple of occasions over the course of the week."
