The Duke and Duchess of Cambridge are already parents to Prince George, seven, Princess Charlotte, six, and three-year-old Prince Louis. But royal author Duncan Larcombe said he “wouldn’t be surprised” if William, 38, and Kate, 39, decide to have a fourth child.
The royal expert said the couple’s children “bring out the best in them” and added that the Duchess is a “natural mother”.
Mr Larcombe told OK! magazine: “I don’t think Kate and William have ever ruled out the possibility of baby number four.
“Their children really bring out the best in them and Kate is a natural mother and very doting with children.
“With Kate, despite her focus on her royal duty, her family still come first.
“I wouldn’t be surprised if they decided on another baby.”
Royal author Katie Nicholl added: “Kate has made no secret that she wanted a fourth baby but William has always been content with three.”
The Duchess was spotted cooing over babies a number of times during her and William’s Scotland tour last week.
During a visit to Starbank Park in Edinburgh last Thursday, Kate chatted to new parents Natalie Randamy, 31, and Rory Stewart, 29, and their nine-month-old daughter Penelope.

In February, a source told Us Weekly that Kate and William wanted to become a family of six.
The insider said: “Having four children was always part of Kate’s plan.
“She put the idea on hold when [the coronavirus pandemic] hit, but now there is light at the end of the tunnel with the vaccine and [Prince George and Princess Charlotte] scheduled to return to school in April.
“She feels ready to start trying again.”
Kate and William welcomed their first child George in 2013 – two years after they married.
Charlotte followed in 2015 and their youngest child Louis arrived in 2018.
The Duchess suffered from severe morning sickness during her three pregnancies.
In a podcast interview in 2020, Kate admitted that this meant she was “not the happiest of pregnant people”.
