Kate Middleton may want to reevaluate her friendships. A “family friend” of the British royals has revealed the Duchess of Cambridge and her husband, Prince William, are planning on adding a third child to their growing brood.

“If wouldn’t surprise me if they were pregnant by Christmas,” the unnamed source told US Magazine Thursday, saying the couple wants a “baby soon.”

While the the 34-year-old Duke and Duchess are reportedly not yet expecting their third bundle of joy to join son Prince George, 3, and daughter Princess Charlotte, 1, the source said the pair is already accommodating for the new baby. According to the magazine, they’re planning to “curtail” their royal tours in 2017 if Kate becomes pregnant.

“I think they both would have been overwhelmed at the thought of a third child a year ago but now it sounds perfect,” added the friend. “They’ve both always wanted a big family.”

While Kate and William may be considering taking a break from their royal duties should baby No. 3 come along, they’re scheduled to make several appearances this month. Kensington Palace has confirmed they will tour Canada Sept. 24 through Oct. 1. Kate and William are also reportedly planning a trip with their children for a week-long stay in Balmoral in Scotland ahead of their tour, though this has yet to be confirmed.
