Prince George turns eight on Thursday, and might already be enjoying his summer holidays at Anmer Hall, the Norfolk home loved by his mother and father.
The oldest Cambridge child and his sister, Princess Charlotte, finished school for the year on 8 July at Thomas's Battersea.
But with his eighth birthday comes a potential life change for George.
He could be sent to boarding school as his father and uncle, William and Harry, were at about the same age.
Prince William went to Ludgrove School in Berkshire, until he passed the test for Eton College, which he attended from the age of 13.
William's younger brother Harry followed in William's footsteps, at Ludgrove and then Eton, although their paths then diverged as Harry went into the Army.
However there is a key difference between the schools William and Harry went to and where the Cambridges have sent George and Charlotte.
William and Harry had to move school each time because they had reached the final year of education in each place.
Before Ludgrove, they went to pre-preparatory school at Wetherby, which educates children up to the age of eight.
And Ludgrove then caters for ages 8-13, before Eton which is for boys aged 13-18.
But at Thomas's, the royal children could go straight through to 13.
As Thomas's is not a traditional royal school, William and Kate might have given a clue about wanting to keep George and Charlotte close to home when they chose it.
Former royal editor Duncan Larcombe told OK magazine: "It's my understanding for some time, possibly even before George was even born, was that William was quite keen that any child he had wouldn't be packed off to boarding school."
Prince Charles and Diana opted not to send William and Harry to Gordonstoun, the Scottish school loved by Prince Philip.
It's where Charles had gone but hated, dubbing it "Colditz in kilts".
Charles was one of the first royals to be sent to school at all, as the Queen had been educated at home alongside her sister, Margaret Rose.
Sources said Diana regularly visited William and Harry at weekends in Berkshire when they attended Ludgrove.
The Cambridges are no stranger to changing royal tradition either, as they decided to keep George and Charlotte slightly closer to home by choosing Thomas's, near to their home of Kensington Palace.
And they might be able to keep them nearby as they grow up, as Thomas's has been given permission to convert the former Royal Academy of Dance building, also in Battersea, into a senior school.
As the youngest Cambridge, Prince Louis, turned three, William and Kate used his birthday to announce he had started at nursery school, going to Willcocks in Kensington.
With the timing of George's birthday in July, they may give an update about plans for the next stage of his education too.
No news is likely to indicate the young prince, and future king, is going to stay put for a few more years.
