The newest royal family member was born at St. Mary’s Hospital in London – just like George and Charlotte. Kate was admitted to the hospital before 6 a.m. (U.K. time) in the early stages of labor on Monday.
The royal baby is the fifth in line of succession after Prince Charles, Prince William, Prince George and Princess Charlotte.
Per royal protocol, an official announcement will be posted with the full details on an easel in the forecourt of Buckingham Palace.
It’s expected that close relatives – led by Kate’s parents, Carole and Mike Middleton, and William’s father Prince Charles and his wife, Camilla, Duchess of Cornwall – will come to see the couple and their as-yet-unnamed newborn before the couple leaves the hospital.
Following the celebratory formalities, including a gun salute in one of the London parks, the couple is expected to take their baby home to nearby Kensington Palace, where great-grandmother Queen Elizabeth may then visit.
Kensington Palace said the name of the baby would be announced in due course and a formal notice of the birth would be posted on the forecourt of Buckingham Palace.
Senior royal doctors consultant obstetrician Guy Thorpe-Beeston and consultant gynaecologist Alan Farthing oversaw the birth.
Both were also called in for the arrival of Prince George in 2013 and Princess Charlotte in 2015.
The new prince, born on St George’s Day, shares a birthday with Lady Gabriella Windsor – the daughter of Prince and Princess Michael of Kent, who was born at the Lindo Wing on 23 April 1981.
Favourite names at the bookmakers include Arthur, Albert, Frederick, James and Philip.
Prime Minister Theresa May tweeted her “warmest congratulations” to William and Catherine.
She said: “I wish them great happiness for the future.”
The baby’s arrival comes just weeks before Prince Harry and Meghan Markle are set to tie the knot at St. George’s Chapel at Windsor Castle.
CONGRATS to all
