Prince Louis Has a Classic Little Brother Moment in New Video with Mom and Siblings — See the Clip Going Viral

Princess Kate took her children — Prince George, Princess Charlotte and Prince Louis — to a baby bank for some volunteering

Prince Louis is going viral (again!).

On Monday, the palace shared a new video of Kate Middleton bringing her three children — Prince George, Princess Charlotte and Prince Louis — to volunteer at a baby bank. The Princess of Wales, 41, George, 10, Charlotte, 8, and Louis, 5, sorted donations, organized clothing and selected toys that they thought other children their age might enjoy.

The footage was filled with adorable moments, from Prince Louis excitedly dubbing a gorilla toy as a "big guy" to Princess Charlotte laughing with delight to see a baby onesie decorated in Welsh flags.

But one relatable moment from Prince Louis is going viral. At around 1:10 in the video, Princess Kate and Princess Charlotte diligently fold clothing while Prince George stands nearby — and Prince Louis hilariously throws another garment onto the pile.

Prince Louis is known for his adorable antics on royal outings — most recently at Princess Kate's Christmas carol concert at Westminster Abbey on Friday. As the family exited the venue, Prince Louis leaned over with puffed cheeks to blow out Princess Charlotte's candle — and their mom saw the whole thing from right behind them!

In May 2023, the young royal went viral for a photo that captured him yawning during his grandfather King Charles' coronation, and photos of Louis covering his ears during a noisy flypast at Queen Elizabeth's Platinum Jubilee also made the internet rounds.

The same weekend, Prince Louis' hilarious dances and faces during the Platinum Jubilee Pageant went viral — prompting acknowledgment from his parents. Kate and William ended the of celebrations for Queen Elizabeth's 70 years on the throne by sharing a social media post that said, "We all had an incredible time, especially Louis…"

Louis is "a cheeky monkey — a typical third child," someone who knows the family previously told PEOPLE. "It's nice that the world got to see him enjoying himself."
