Kate wore a yellow patterned dress and cradled the sleeping baby wrapped in a white blanket in her arms. William drove his wife and daughter to Kensington Palace in a black Range Rover after carrying the baby in a car seat. The baby who assumed the title 'Her Royal Highness Princess of Cambridge' is the first to use the title princess since Princess Eugenie, 25, younger daughter of the Duke of York. The official notice announcing the new princess' arrivalhas now been put up on an easel of the Buckingham Palace forecourt, as per royal tradition.
