An adorable round of applause from Prince George, Princess Charlotte and Prince Louis!

Kate Middleton and Prince William‘s three children made an appearance on the couple’s social media pages on Thursday, enthusiastically clapping for all those helping patients affected by coronavirus as they joined in on a viral hashtag initiative amid the pandemic.

“To all the doctors, nurses, carers, GPs, pharmacists, volunteers and other NHS staff working tirelessly to help those affected by #COVID19: thank you,” the video was captioned, along with the hashtags ##ClapForOurCarers, #ClapForCarers, #ThankYouNHS and #ClapForNHS.

Prince Louis, who turns 2 next month, stands between his older siblings — and sweetly glances up at them both as they all clap in unison. George, 6, and Charlotte, 4, smile throughout the clip, with the little princess letting out a giggle towards the end.

Kate Middleton, Prince William and their three children are believed to be staying at their Sandringham country estate, Anmer Hall, which is about 110 miles north of London in Norfolk. The family of five is based at Kensington Palace in London, but they often escape to their second home — a gift from the monarch for the couple’s 2011 wedding — during breaks from school. Given that Prince George and Princess Charlotte‘s school closed in favor of online learning due to the pandemic, the children can do their home schooling from the country.
