LONDON (AP) - Prince Harry and Meghan have named their son Archie.

Buckingham Palace says that the baby's full name is Archie Harrison Mountbatten-Windsor.

The palace made the announcement hours after the couple posed with the two-day-old for the media. He also met his great-grandmother, Queen Elizabeth II, for the first time.

He is the queen's eighth great-grandchild and is seventh in line to the British throne.

The new arrival is the eighth great-grandchild of Queen Elizabeth II, who smiled when asked about the baby's arrival at a luncheon Tuesday.

Asked if life is good, the 93-year-old monarch said: "Yes, thank you."

The baby boy is the first of her great-grandchildren to have an American parent. His mother Meghan is the daughter of a white man and a black woman, bringing a biracial heritage to the House of Windsor.

Trevor Phillips, a retired black broadcaster who headed Britain's Equality and Human Rights Commission, wrote an open letter to the royal baby, saying his arrival reflects British society's more open attitude nowadays and the increasing inclusiveness of the royal family.

"This is a family that lives the reality of a multicultural world daily," he said. "It's their job: to interact with people of different backgrounds to themselves on behalf of the nation, and to treat them all with respect. I have to tell you, they are pretty good at it."

He went on to tell the baby: "Whether you like it or not, you're going to have a special place in the nation's heart."

Prince William, Harry's older brother, joked Tuesday that he will be glad "to welcome my own brother into the sleep deprivation society that is parenting!"

"Obviously thrilled, absolutely thrilled, and obviously looking forward to seeing them in the next few days when things have quietened down," William told reporters.

The birth produced a moment of high drama likely to be replayed for the rest of Harry's life. The prince, who has battled mental health challenges since the abrupt loss of his mother at a young age, emerged with the world's most satisfied grin Monday afternoon to announce the birth of his son before TV news cameras.

"We're both absolutely thrilled and so grateful for all the love and support from everybody out there. It's been amazing, so we just wanted to share this with everybody," the normally press-shy royal gushed.

Harry also burnished his feminist credentials - and paid tribute to mothers around the world - after witnessing the birth.

"It's been the most amazing experience I could ever have possibly imagined," he said. "How any woman does what they do is beyond comprehension."
