The Queen has been at Kensington Palace to meet her great-grandson for the first time and see his parents before heading off on her summer holiday.
Her Majesty, who will travel to Balmoral on Friday, spent half an hour with the Duke, Duchess and Baby Cambridge, as the guessing game over the future king's name continues.
She told guests at a Buckingham Palace reception last night that she was 'thrilled' at the birth of her great-grandson, and today William and Kate may have discussed potential names with her.
On the eve of the so-far-unnamed baby's birth, the Queen told a 10-year-old schoolgirl that she didn't mind if it was a boy or a girl, adding: "I would very much like it to arrive. I'm going on holiday."
Dressed in a turquoise floral outfit she looked relaxed and happy as she left, having travelled the short distance from Buckingham Palace without the Duke of Edinburgh, who is still convalescing at Windsor Castle following exploratory abdominal surgery last month.
Baby Cambridge has spent his first night at home after a dramatic evening where the waiting world had its first glimpse of him.
