Prince Harry and his wife Meghan posed with their two-day-old son at Windsor Castle. Standing in the vast, red-carpeted St. George's Hall, Meghan declared the baby was "a dream" and called motherhood "magic." Baby Sussex, whose name has not been announced, slept through his first photo-op in his father's arms, wrapped in a white blanket and wearing a matching cap. When asked which parent the baby took after, Harry said it was too soon to tell. The couple left the photo call to introduce the baby to his great-grandparents, Queen Elizabeth II and Prince Philip. The infant is the eighth great-grandchild of 93-year-old Elizabeth, Britain's longest reigning monarch. Family members have welcomed the new arrival. Prince William, Harry's older brother, joked on Tuesday that he would be glad "to welcome my own brother into the sleep deprivation society that is parenting!"
