The newest arrival to the Royal household arrived this week. Prince Louis Arthur Charles was born on Monday weighing in at 8lb 7oz becoming the Duke and Duchess of Cambridge’s third child. He is 5th in line to the throne just behind his two siblings George and Charlotte. His name honours Louis Mountbatten (uncle of Prince Philip, Duke of Edinburgh). As the biggest feel good news story of the week, we couldn’t help but post one of the first photos of the young prince.
