The Latest on the royal baby (all times local):
Meghan and Prince Harry have shown their new son to the public, with the proud new mother declaring that the baby is "a dream."
The Duke and Duchess of Sussex posed with their son for cameras at Windsor Castle - the first in a lifetime of photo calls for the two-day-old baby, who is seventh in line to the throne.
Harry cradled the apparently sleeping baby, wrapped in a white blanket and wearing a matching cap, in his arms.
Meghan declared motherhood to be "magic."
She said the baby had "the sweetest temperament" and has "just been a dream."
Asked which parent the baby took after, Harry said it was too soon to tell: "His looks are changing every single day, so who knows?"
The newborn son of Meghan, the Duchess of Sussex, and Prince Harry is set to attend his first photocall and meet his great grandmother - all in one day.
Harry and Meghan are expected to introduce the infant, known only as Baby Sussex for the moment, to Queen Elizabeth II and show off the baby to the media on Wednesday.
Baby Sussex was born Monday at 5:26 a.m. (0426 GMT; 12:26 a.m. EDT) at an as-yet-undisclosed location. An overjoyed Harry said he and Meghan are "thinking" about names.
Family members have welcomed the new arrival, with Prince William saying on Tuesday he was "absolutely thrilled."
The infant is seventh in line to the British throne and is the eighth great-grandchild of 93-year-old Elizabeth, Britain's longest reigning monarch.
