LONDON — Tired but beaming, new parents Meghan and Prince Harry presented their 2-day-old son to the world as he slumbered Wednesday and also revealed his name: Archie.

The royal couple, known as the Duke and Duchess of Sussex since their marriage not quite a year ago, said the full name of the child born seventh in line to the British throne is Archie Harrison Mountbatten-Windsor.

The baby slept peacefully through his carefully orchestrated media moment. His mother, making her first public appearance since giving birth early Monday, called Archie “a dream” who “has the sweetest temperament.”

Harry and Meghan did not choose an aristocratic title for their son. He is not a prince but could have been given the title “Lord” before his first name.

Instead he will be known for now as “Master Archie Mountbatten-Windsor.”

The surname, used by some members of the royal family, was created to recognize the lineage of both Queen Elizabeth II and her husband, Prince Philip.
