Last in the the Prince and Princess of Wales's brood is four-year-old Prince Louis Arthur Charles of Wales. The youngest sibling was born at 11.01am on 23 April, 2018.
Prince Louis made quite the entrance at the late Queen Elizabeth's Jubilee celebrations, and reminded parents all over the world that kids will be kids. For starters, the young prince was pictured screaming with his hands over his ears as planes flew over the balcony at the 2022 Trooping the Colour, before becoming a ball of energy at the jubilee concert. He may be the youngest of the siblings, but he's certainly the feistiest!
