The trio will be visiting their home in Norfolk - Anmer Hall, which is on the Queen's Sandringham Estate. But according to The Mail on Sunday the visit could be for longer than expected and couple could spend the next couple of years there.
"William and Catherine are not pavement people; they prefer the countryside," the source said. "They really miss Anglesey. They can't wait to move to Anmer Hall.
"All of George's things will be there - it's very much going to be their family home.
"William has told me that while Kensington Palace is their long-term home, and I think the plan is that it will always be so, they both love the countryside."
Last year, Kate whisked baby George off to Mustique (where Cheryl just married her man Jean-Bernard Fernandez-Versini) for a family break with the Middleton clan while Wills was studying at Cambridge University.
