Prince LouisandPrincess Charlottehad a total sibling moment atTrooping the Colour!

The little prince and princess joined other members of the royal family atKing Charles’ birthday parade last Saturday, where theytraveled in a carriageto watch military processions at Horse Guards Parade and caught the epic flypast fromthe balcony of Buckingham Palace. In a blink-and-you’ll-miss-it moment shared to social media, Charlotte, 8, and Louis, 5, accidentally knocked their heads together while out on the balcony.

As seen in an Instagram video from@Royal.fairy.tale, Charlotte leaned to her right just as Louis turned to chat withKate MiddletonandPrince William, and their heads collided.Prince George, 9, didn’t react to what happened — and neither did Louis! — who kept talking. The tap seemingly whacked Charlotte harder than Louis, who gently touched her temple after the bump.

The Prince and Princess of Wales’ children seemed to be on their best behavior during the festive flypast, where the Red Arrows Aerobatic Team of the Royal Air Force soared overhead. Prince Louis was ready for the noise and didn’tcover his earslike last year! Kate and William’s youngest son attentively stood as “God Save the King” was played and evencharmed the crowdwith a salute before retreating into the royal residence.

Fans also got a glimpse of Prince Louis’playful personalityduring King Charles andQueen Camilla’s coronation celebrations just a few weeks ago. The little prince sweetly held hands with Charlotte on the way into Westminster Abbey for the crowning on May 6, butcouldn’t help but yawnat one point during the two-hour church service.

Louis later made a few funny faces during the carriage ride back to Buckingham Palace andclapped, pointed and dancedwhen he appeared on the balcony there. He did not attend the Coronation Concert the next day (likely past his bedtime!) but tagged along with his family forThe Big Help Outon May 8, which was a bank holiday in the U.K. to encourage volunteer work.

Prince William, Princess Kate and their three kidsvolunteeredat the 3rd Upton Scout Group in Slough to pitch in on various projects, and a fellow helper exclusivelytold PEOPLEthat Charlotte was ever ready to keep Louis in line.

“She was advising him, obviously! ‘Don’t do that, Louis!’ — things like that,” Scout helper Anne Edwards said of what she saw when the siblings painted planter blocks, adding that it was sweet to see the Wales kids excited about volunteering.

“They were very relaxed and joining in, like normal kids. That was what was really nice about it,” Edwards said.
