Kate and William show off the royal baby.

The royal baby, born Monday to William and Kate, the Duke and Duchess of Cambridge, is expected to leave the hospital soon with his parents.

Earlier Tuesday, Prince Charles saw his new grandson, the Prince of Cambridge, paying a visit to St. Mary's Hospital in London along with his wife, Camilla.

The newborn stands a good chance of reaching the prize that has thus far escaped Charles' grasp -- becoming king of England.

UPDATE: The new parents and baby have made their appearance. Watch what they had to say above.

The infant prince's maternal grandparents, Michael and Carole Middleton, also paid a visit, with the new grandmother emerging to call the royal baby "absolutely beautiful."

The Times' London bureau chief, Henry Chu, has been following the royal birth, and posted these tweets on the baby's first full day as not-quite-ruler of the empire upon which the sun never sets. (Or does it?)
