One fan wrote on X: “This video is just precious.”
Another said: “How special! Thank you so much for sharing with us. Hope Prince Louis is having the best birthday ever!”
A third commented: “What a sweet video.”
Someone else said: “The young prince is growing up fast, what a lovely video.”
The prince is likely to be celebrating his birthday with his family, including his parents Prince William and Princess Kate, and his siblings Prince George, 11, and Princess Charlotte, nine.
The young royal is also set to have a special birthday cake for his big day, which is likely to have been made by Princess Kate, who told baking legend Mary Berry in 2019 that it has become a tradition for her to make cakes for her children on their birthdays.
She said: “I love making the cake. It's become a bit of a tradition that I stay up 'til midnight with ridiculous amounts of cake mix and icing and I make far too much. But I love it.”
