The five photos of Louis show the Duke and Duchess of Cambridge’s third child with his hands covered in paint as he creates his rainbow poster, echoing similar artworks made by children across the country and put up in windows of their homes.
All the photos of the young prince were taken this month by Kate at their family home in eastern England where they are staying during the coronavirus lockdown, Kensington Palace said.
Louis, fifth in line to the throne, has a six-year-old brother, Prince George, and four-year-old sister, Princess Charlotte and last month the family released a video of them joining a nationwide applause of thanks to the nation’s healthcare workers.
Earlier this week, Kate disclosed they had been home schooling the children, but had not let them have a break during the Easter holidays.
“Don’t tell the children, we’ve actually kept it going through the holidays. I feel very mean,” she told a TV channel.
Louis’s celebrations come just days after his great grandmother, Queen Elizabeth, celebrated her 94th birthday.
