Speculation is rising that the little prince, almost 2, will join his parents at Buckingham Palace on Saturday

With jets flying overhead and scarlet-uniformed soldiers lined up below, could there be a better sight for a little prince?

That’s the spectacle nearly 2-year-old Prince George could survey from the balcony at Buckingham Palace for his Great-Granny Queen Elizabeth’s annual birthday extravaganza, known as Trooping the Colour, on Saturday.

Asked whether the heir will make his debut on the historic Buckingham balcony, a palace official would only tell PEOPLE, “Watch this space!”

George’s dad Prince William is set to take part in the annual birthday parade for Queen Elizabeth, 89, on June 13, and his wife Kate may well join him and other members of the decorated royal family.

Although George would skip the parade and his 5-week-old sister Charlotte is most certainly too young to attend – “it’s conceivable [George] could be in his mum’s arms on the balcony for the fly-past,” says Dickie Arbiter, a former press secretary at the palace and author of the recent On Duty With The Queen.

“At the end of the day the cameras will be on him and the focus will be taken away from the Queen,” Arbiter adds. “It is her day.”

Prince William was around George’s age when he was first brought out for the crowds by his parents in 1984 – and his brother Prince Harry was even younger, at just nine months.

“William likes to protect his family rather than expose them and he may make the decision to say ‘not this time, maybe next year,’ ” says Arbiter.

Mark Stewart, a veteran photographer who has covered the Trooping of the Colour ceremonies and balcony shots for more than 20 years, believes there is another consideration where a young child is concerned.

“If you are under the fly-past, it is incredibly noisy on the ears. Sometimes there are about 14 different planes. It might be too much for him,” he tells PEOPLE.

“But, saying that, he did behave beautifully at the hospital and they may decide he will be fine with it. Let’s hope so.”

For her part, experienced chronicler of royal affairs, Ingrid Seward, editor-in-chief of Majesty magazine, says, “They have always produced the youngest heir. The Queen loves to talk about family and continuity and the succession and I would think someone would think it would be good to have George there.

“My guess is that George will appear. It is the continuity of the family. I’m sure she will be around, looking at her longevity, but the family are aware that each year could be her last.”
