There are rumours that the British royal family is planning to get bigger soon. Prince William and Kate Middleton are allegedly setting their sights on having a third child in the near future, since they wish for all their children to grow up close in age.

Prince George is turning three years old in July 2016, while Princess Charlotte recently turned one in May. Some of their friends reported that the royal couple is planning to add a third child soon.

Insiders told Vanity Fair that William and Kate want at least three children and for them to be close in age.

The Telegraph reports that according to their friends, the Duchess of Cambridge will have her third baby before she turns 35 years old. She was born in January 1982, which means that she has less than one year to go forth with her plans if the talks are true.

Kate has two siblings, which may have been one of the reasons why she and William are aiming for at least three kids, too. Reportedly, Kate told friends that she wants at least three children so that Prince George and Princess Charlotte would have the opportunity of having the same kind of family environment that she experienced.

If Kate gives birth to a third baby in 2017, the royal couple would have had three kids born within a span of about four years only, which is well within their intention to have their brood grow up close in age. The three potential siblings would have the chance to interact with each other better and enroll in the same school.

According to The Independent, at present, the royal couple mainly lives in Amner Hall. They frequently visit Kensington Palace for business purposes. William reportedly wants to stay in their country estate as much as possible, to provide his family with more privacy and allow them to live a more normal life compared to what he went through as a child. Prince George is currently enrolled at Westacre Montessori nursery in Norfolk. More updates and details on the royal couple’s next baby are expected soon.
