School is out for summer - and Prince George, Princess Charlotte and Prince Louis are currently enjoying their long break with their parents the Duke and Duchess of Cambridge.
But it's set to be all change when class starts again in September as not only are George and Charlotte rumoured to be starting a new school, four-year-old Louis is set to join them. He currently attends nursery now and will be ready to make the step up to regular school next month. And it could be that Louis follows in his older siblings' footsteps and adopts a different name at school.
For example, George's name is George Alexander Louis, while his official title is His Royal Highness Prince George of Cambridge - but at school, he goes by George Cambridge.
Similarly, Charlotte's full name is Charlotte Elizabeth Diana, and her official title is Her Royal Highness Princess Charlotte of Cambridge, but at school, she is simply known as Charlotte Cambridge.
Their dad, Prince William, and uncle, Prince Harry, followed the same rule while at school, using Charles' title - Wales - as their surname. William and Harry also continued to use this moniker throughout their military careers.

So it's likely that Louis will go by the name Louis Cambridge when he starts his formal education.
It comes as the Cambridges are reportedly upping sticks from Kensington Palace and moving into the four-bedroomed Adelaide Cottage on the Queen's Windsor Estate.
Their children are likely to be educated locally and are rumoured to be joining Lambrook School in Berkshire as day pupils.
The co-educational school charges up to £7,000 a term - plus a further £1,481 for boarding - and many of its leavers eventually head off to prestigious secondary schools including Eton.
It caters for both boys and girls, making it a more convenient option for the school run as both George and Charlotte can attend.
They will have to attend Saturday School which takes place each week, however, followed by an afternoon of sports fixtures for pupils in Year 5 and above.
William and Kate have reportedly been seen visiting the school "multiple times" - with William even chatting to one pupil about Latin classes.
Making the move from London to Windsor would be a huge step for the Cambridges.
But one royal insider told the Daily Mail that the relocation is due to William wanting to be closer to the Queen as she continues to delegate additional royal duties to him.
William is said to speak to his grandmother, who mostly spends all of her time at Windsor Castle, on the phone several times a week.
