One of the highlights of the new programme was that super sweet snap of Prince Louis with his granddad. But while the fifth in line to the throne is still at the stage of saying hello by grabbing grandpa's fingers, his big brother and sister are already calling Charles a very special name indeed. Prince George and Princess Charlotte call him "Grandpa Wales" which as well as being super sweet is also filled with family meaning. The Queen used to call her grandfather, King George V, Grandpa England. It's enough to bring a tear to even the most royal eye.
