Prince Louis demanded all the attention during his great-grandmother's Platinum Jubilee celebrations.
With all that the focus on little Louis, what was his older brother's reaction?
And how is the rest of his family feeling about all the scrutiny of their youngest member?
Keep watching to find out.
The Queen's Platinum Jubilee celebration weekend will be remembered for many things: The hologram.
The parade pageantry.
A lot of flags.
And, of course, the historic milestone the celebrations marked: Queen Elizabeth II's
70-year reign, the longest of any British monarch.
There was also all the drama surrounding Prince Harry and Meghan Markle taking part in select
events, given that they are no longer officially working royals.
As such, the Duke and Duchess of Sussex weren't allowed to stand on the balcony of Buckingham
Palace during the Trooping the Colour ceremony.
It was also reported that the Queen didn't agree to take a photograph with Harry and
Meghan's youngest daughter Lilibet for fear of the photo's release overtaking the headlines.
She did, however, meet with her namesake one-year-old great-granddaughter, and the meeting reportedly
went well.
And then, there's 4-year-old Prince Louis.
The third and youngest child of Prince William and Kate Middleton officially stole the show
by acting pretty much like any other preschooler.
"There's quite a significant amount of people calling him brattish and entitled."
Prince Louis is fifth in line for the British throne, after his grandfather, Prince Charles,
his father, Prince William, and his older siblings, Prince George and Princess Charlotte.
But just because the royal was born into a position of power most people could only dream
about, he's also still very much a kid.
Hello!
magazine notes that he enjoys riding his bike, watching construction vehicles, and munching
on cereal for breakfast.
He also gets bored at events just like other kids his age.
During the Jubilee celebrations, he entertained the world with his adorable faces and over-the-top
antics.
Some onlookers chose to criticize his behavior, but the New York Post talked to a group of
child behavior experts who said it was totally normal behavior for a 4-year-old.
As licensed therapist Kaitlin Soulé told the outlet,
"With children around his age, part of their developmental task is to push boundaries and
figure out how to be in the world."
"I can't think of a better example that shows that this is developmentally appropriate."
Everyone seems to have an opinion about Prince Louis making faces while the world was watching.
But it wasn't just Twitter that was abuzz about the youngster's hijinks — along with
mom Kate Middleton's attempt to tame him.
Prince George also seemed to delight in his younger brother's silly behavior during the
Platinum Jubilee Pageant.
George, who is 8 years old, apparently found Louis' attention grab hilarious, laughing
and covering his face during his little brother's outbursts.
The eldest son of Prince William also turned to his dad at one point as if to gauge his
reaction.
While William was definitely more reserved, it was pretty clear the Duke of Cambridge
was also similarly charmed by his son's zany gestures.
One Twitter user pointed out that when William was a kid, he too had his moments in which
it was obvious being in public was the last thing he wanted to do.
Publicly, Prince William and Kate Middleton seemed to have fun with Prince Louis' Jubilee
antics.
Their official Twitter account even tweeted a humorous message alongside an eyes emoji.
It read:
"We all had an incredible time, especially Louis..."
But no matter what their social media account proclaimed, it seemed like the Duchess of
Cambridge made at least a small attempt to discipline her son in the moment.
It was mostly to no avail, with Louis continuing to act out for the world to see.
And, of course, the royal family is always under a microscope, so parents and experts
took the opportunity to alternately criticize and defend Kate's actions.
Meanwhile, Princess Charlotte seemed to also try to get her brother to act the part of
a prince, even chastising him at one point.
Yet even big sister couldn't get the antsy prince to cut out his fidgeting.
He simply carried on creating meme fodder that will last for years.
