Prince William and Kate are considering taking their eldest son, nine year old George, to the Queen's funeral at the request of senior advisors.
The new Prince and Princess of Wales have been told it will send a "powerful and symbolic" message.
At just nine and having embarked on his first year of secondary school, Prince George is now second-in-line to the throne.
Aides have told his parents that seeing the young Prince attend the funeral of the late monarch - whom he affectionately called "Gan Gan", would be good for the public.
According to the Daily Mail, one insider said: "Courtiers are keen for Prince George to be at the funeral in some capacity, if only to reassure the nation of the order of succession."
Another palace source added: "It’s currently under discussion. No decision has been made yet."
George was said to have a close relationship with his great-grandmother.
The Queen marked his ninth birthday in July by sharing a picture of them together on the balcony at Buckingham Palace at the Jubilee weekend.
The Monarch’s official Instagram page featured the post: "Happy 9th Birthday Prince George!" along with a celebratory cake emoji.
One Christmas the monarch shared a snap showing George stirring the Christmas pudding mixture as his father, grandfather and great-grandmother looked on.
Prince George and his younger siblings, Princess Charlotte and Prince Louis, have not been seen in public since the death of the Queen on Thursday, September 8.
Two of the late Queen’s other great-grandchildren, Mia and Lena Tindall, were at Westminster Hall on Friday for her lying-in-state.
They were in the gallery with their parents Zara and Mike Tindall as their grandmother, Princess Anne, took her place alongside her three brothers for a silent vigil beside the Queen’s coffin.
Last week, William revealed how walking behind his grandmother’s coffin as it left Buckingham Palace for the last time on Wednesday had evoked memories of his mother Princess Diana’s funeral 25 years ago.
William and Harry, then just 15 and 12, were just boys battling their grief when they were thrown under the public eye as they followed Diana’s coffin along the same route down the Mall and Whitehall.
It became one of the defining images of the day and left a lasting impact.
William has previously said it was "one of the hardest things I’ve ever done", while Harry said: "I don’t think any child should be asked to do that, under any circumstances."
Despite the reservations he may have about putting his own son in that position, Prince William and Kate have increasingly included their children in public events and duties.
The children were a popular feature with the public on the royal balcony for the Platinum Jubilee celebrations.
