On Sunday afternoon, Prince Louis was observed in the Royal Box at the Jubilee Pageant shushing his mother, Kate Middleton, by placing his palm over her lips, as if he'd had enough of the Platinum Jubilee.
At Sunday's Jubilee Pageant march, Louis, Prince William and Kate Middleton's youngest son, could barely sit still in the grandstand.
In a video, Louis can be seen poking his tongue out at his mother and making funny expressions at her, as well as covering her lips with his hand while she speaks to him.
As of Sunday afternoon, the video had 1,200 likes and nearly 200,000 views. Some commenters chastised him for his actions, while others begged the internet to be patient with the toddler.

On the fourth and last day of Queen Elizabeth II's Platinum Jubilee, Prince Louis continued to steal the spotlight.
The 4-year-old king, whose antics earlier in the celebration drew comparisons to former New York Mayor Rudy Guiliani's son Andrew's on Saturday Night Live, spent much of Sunday's parade diverting his parents and grandfather.
The young prince appeared unimpressed in the day's celebrations in photos, giving his mother, the Duchess of Cambridge, a "stinky face."
Louis sat on his grandfather Prince Charles' knee at one point, with the heir-apparent to the British throne pointing to the march in an apparent attempt to pique Louis' interest.
