HELLO! magazine reports that whilst the Duke and Duchess of Cambridge, who are currently expecting their third child, travel around the two countries, George and Charlotte will remain at home in the UK.
In the official statement confirming the royal tour, which will take place from Tuesday 30th January to Friday 2nd February, the youngsters are not mentioned.
Four-year-old Prince George has attended several royal tours already, undertaking a trip to New Zealand and Australia with his mum and dad when he was just eight months old.
Younger sister Princess Charlotte, two, made her royal tour debut during the family's visit to Canada, and the pair have since travelled to Germany and Poland with their parents, making official appearances at the airports in both countries.
However, the visit to Sweden and Norway marks the first royal tour since Prince George started school at Thomas' Battersea, and this is likely to be the reason why the adorable duo will be staying put.
The latest royal tour was originally due to take place in November of this year, and set to cover Finland as well as Norway and Sweden. However, the bulk of the occasion had to be postponed as Kate was suffering from severe morning sickness throughout the early stages of her pregnancy.
William instead jetted to Finland alone, where he marked the centenary of the country's independence, and met with Santa Claus at a Christmas market to give him little George's handwritten wishlist, amongst other engagements.
A photograph of the note showed that Prince George has just one request for the festive season this year: a police car.
