Today Prince Louis celebrates his third birthday. We haven't seen much of Louis over the past year because of coronavirus lockdowns, but when we have seen him he's shown us plenty of personality. Clapping for the NHS, showing off his painting skills and having a chat with David Attenborough are among his highlights, as well as having lots of fun with siblings Prince George and Princess Charlotte. Louis is Prince William and Kate Middleton's youngest child. | The Royal Family Channel
