Royal children must travel abroad with their parents when on royal tours. Prince George and his sister Princess Charlotte are already no strangers to the jet-set lifestyle, despite only being seven, five and two-years-old respectively.
For instance, on a royal tour to Canada, the two little royals both wore the colour blue as did their parents.
It is likely this theme will be continued once the family embark on their net royal tour.
This is not the only rule little members of the Royal Family must follow.
According to one royal etiquette expert, the children must be prepared for public appearances and formal events from a young age.
This includes both at home and abroad.
They are introduced to etiquette lessons “as soon as they’re old enough to sit at a table,” says etiquette expert Myka Meier.
“They are raised having formal meals, going to formal events and practising everything from voice levels to dressing appropriately to even, of course, how to curtsy and bow,” she told People Magazine.
These rules will then be put into practise when the children are on global escapades with their parents.
Etiquette will continue throughout their lives well into adulthood too.
One of these comes into play as soon as the royals touch down abroad.
When departing the royal plane it is vital that they maintain a sense of grace and elegance.
Reports state female royals must not bow their heads, and instead must keep their chins parallel to the ground, pointing their toes as they walk.
They may rest their hand upon a bannister or rail for extra support if there is one, but if not they must keep their hands at their sides.
If the female royals are accompanied by a male royal, he may assist her by offering his arm as support.
