At one stage in the future, Prince George will become a senior royal and will start carrying out official engagements and foreign visits of his own.
While he has already accompanied his parents to New Zealand, Australia, Canada, Poland and Germany and enjoyed private trips to Jordan, France and Mustique, many will wonder what age the nine-year-old Prince will be when he makes his solo debut.
As there are no strict rules that dictate what age the royal has to be, it is likely that his first appearance will be similar to those of Prince William and Prince Harry who both debuted at the age of 23.
If he follows in his father's example, Prince George could carry out his first engagement in his early twenties.
In Prince William's case, this event coincided with his first solo tour to New Zealand in 2005 when he joined the British and Irish Lions rugby team and then represented the Queen at events to commemorate the end of the Second World War.
As well as attending these events, the Prince planted a tree at Government House, attended rugby training sessions and threw the ball in the water to signal the start of a championship water polo game - a sport that he was very fond of at University.
While Prince William's first official visit to the US didn't come until 2011 when he and Kate spent time in California after a successful nine days in Canada, it is a likely contender for where Prince George could go in his early days as a senior royal.
While uncle Harry's first tour was a rather exotic one to Brazil, The Bahamas and Jamaica.

A visit to Washington D.C. was one of King Charles' first official visits without his parents when he and Princess Anne visited the White House as guests of President Richard Nixon.
This is a similar scenario for the late Queen as she made her first visit Stateside when she was still a Princess in 1951 and was pictured with US President Harry Truman.
When the time comes, it is likely that George will first be dispatched to a key Commonwealth country such as Canada, Australia or New Zealand - but a visit to the States would also be seen as vital owing to the warm relationship between the UK and US.
Following the announcement that The King and Queen Consort will undertake their first state visit to France and Germany this month, it was previously revealed that the monarch is determined to carry out many more foreign tours in the early years of his reign.
In what will be a two-year blitz of foreign travel aimed at "extending a hand of friendship and support", it is understood that The Prince and Princess of Wales will also play an instrumental role.
A royal source previously told The Mirror: "The King and his family are keen to hit the ground running in these crucial first few months and years of his reign.
"He certainly wants to carry on the long-held mantra from his late mother of being seen to be believed, and is very keen to get out and meet as many people as possible."
Sources have said the royals could undertake as many trips as the Queen packed in during the 1970s, with her 52 Commonwealth visits and 21 trips to other countries to mark her Silver Jubilee.
The King - who has so far visited 45 of 56 Commonwealth countries - has already opened discussions with his chief advisers over visits to major British realms including Australia and Canada “as soon as possible”.
Royal sources also said the monarch is “acutely aware” that his accession to the throne comes at a time of unrest across a number of realms, especially in the Caribbean, as they assess whether to become republics.
