UK’s Duchess of Cambridge, Prince William welcome new baby boy

LONDON — Catherine, Duchess of Cambridge, the wife of Britain’s Prince William, has given birth to a son, the royal family announced Monday.

The Duke of Cambridge was present for the birth of the couple’s third child, at 11 a.m. local time at St. Mary’s Hospital in Paddington, West London.

The newest arrival to the royal family weighs 8lbs 7oz (3.8 kilograms), and both mother and baby are “doing well,” according to the Palace.

“The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall, Prince Harry and members of both families have been informed and are delighted with the news,” Kensington Palace said in a statement on Twitter.

A golden easel bearing a framed notice announcing the birth was placed on display in front of Buckingham Palace on Monday afternoon. The bulletin will be on display for approximately 24 hours.

The practice of posting a bulletin on the occasion of a royal birth goes back to at least 1837, when Buckingham Palace became the Brtish monarch’s official residence.

The royal baby is fifth in line to the British throne, after grandfather Prince Charles, father Prince William and two siblings.

The newest addition to the royal family is a younger brother to Prince George, 4, and Princess Charlotte, 2, and the Queen Elizabeth II’s sixth great-grandchild.

Prince George was born at the Lindo Wing in 2013, and Princess Charlotte in 2015. Their father William was also born at the same facility.

The duchess’ pregnancy was announced in September. At the time, she was said to be suffering from hyperemesis gravidarum, which involves nausea and vomiting more severe than the typical morning sickness many women suffer during early pregnancy. The duchess was affected by the same condition during her two previous pregnancies.

As her symptoms eased she returned to public engagements, making appearances alongside William, Harry and his fiancee, Meghan Markle.

The birth comes just weeks before the wedding of Harry and Markle at St. George’s Chapel in Windsor on May 19.

William and Kate will mark their own seventh wedding anniversary on April 29.

The news of a royal birth is traditionally announced on a gilded easel placed outside Buckingham Palace. Large crowds gathered outside in July 2013 to see the announcement of the arrival of William and Kate’s first child.

The couple announced his name, George Alexander Louis, and that of their daughter, Charlotte Elizabeth Diana, a couple of days after each was born.

Among bookmakers’ favored names for the couple’s third child are Arthur, Albert and Frederick.
