(CNN) – It’s a boy! Catherine, Duchess of Cambridge and husband Prince William on Monday welcomed their first child. The baby boy was born at 4:24 p.m., weighing 8 pounds 6 ounces. A name has not yet been announced for the child, who is now third in line to the throne.
The royal baby’s birth is “wonderful news,” British Prime Minister David Cameron said Monday night. “I’m sure that right across the country and indeed right across the commonwealth, people will be celebrating and wishing the royal couple well,” Cameron said. “It is an important moment in the life of our nation, but I suppose above all it’s a wonderful moment for a warm and loving couple who got a brand new baby boy.”
The Duke and Duchess of Cambridge spent some time with their new baby before calling family members — starting with Queen Elizabeth II — to announce the birth, a Kensington Palace source told CNN’s Max Foster.
Prince William remained at Catherine’s side throughout the labor and the baby was born vaginally, not via a C-section, a Kensington Palace source told CNN’s Max Foster.
Prince William and wife Catherine “could not be happier” over the birth of their first child, he said Monday night, according to a Kensington Palace spokesman.

As a nation and the world awaited news of a child who could one day sit on the British throne, Catherine, Duchess of Cambridge, was experiencing a normal labor on Monday, Kensington Palace said.
The duchess and Prince William, Duke of Cambridge, traveled by car from Kensington Palace to the Lindo Wing at St. Mary’s Hospital, his office at Clarence House announced at 7:37 a.m. Monday (2:37 a.m. ET.) Kensington Palace issued a progress report about 90 minutes later.
The hospital, next to Paddington Station in London, is where William and his brother Prince Harry were born.
The duchess’ mother, Carole Middleton, was expected to be on hand at the hospital.
The baby’s name will not be announced when its sex and birth weight are posted on a notice board at Buckingham Palace, a Kensington Palace spokesman said. A formal press release containing details of the birth will be issued shortly before the formal signed announcement leaves the hospital, on its way to Buckingham Palace.
The baby’s name may be announced when the family leaves the hospital, CNN royal correspondent Max Foster reported. Prince William’s name was announced a few days after birth, his brother Harry’s on departure from hospital.
Some British parents have delayed naming their newborns in recent days in hopes of either copying or avoiding the royal name, he said.
British bookmakers favor the names Alexandra, Charlotte, Elizabeth, Victoria, Grace, James and George. The field is open for both boys’ and girls’ names because royal sources said the parents did not want to know their child’s sex in advance.
The child’s title will be His or Her Royal Highness Prince or Princess (the baby’s name) of Cambridge, St. James’s Palace said this month.
Protocol dictates that the first to know about the arrival of the baby will be Queen Elizabeth II, Prime Minister David Cameron and the governors general of each of the Commonwealth nations — along with the rest of the royal and Middleton families.
The queen returned to Buckingham Palace on Monday from Windsor Castle, another of her official residences. Crowds have been gathering outside the palace gates as news of the birth is awaited.
Meanwhile Monday, on a visit to the city of York, in northern England, Prince Charles was given a gift to pass on to his grandchild by a child among the crowd of well-wishers.
“I’ll see what I can do,” said Charles, adding that the baby “hasn’t quite appeared yet.”
British Prime Minister David Cameron sent his “best wishes,” to the Duchess of Cambridge during her labor.
“The whole country is excited with them, so everyone is hoping for the best,” he said.
Justin Welby, the archbishop of Canterbury and head of the Church of England, tweeted: “My thoughts and prayers are with Kate and the whole family on this enormously special day.”
The baby will be third in line for the throne now occupied by the queen. Her son, Charles, will succeed her, followed by his son, William.
Thanks to a change agreed by the leaders of the Commonwealth countries in 2011 and passed into law this year, the baby’s place in the order of succession will be the same regardless of sex.
Previously, boys automatically trumped female siblings. So a first-born daughter could be pushed out of line by a younger brother.
The British monarch is also head of state in 15 Commonwealth countries, including Australia, Canada, New Zealand, Belize and Jamaica — so many people there will also be waiting for news of the birth of their future sovereign.
The royal birth is expected to be good for business. The UK-based Centre for Retail Research estimates retailers will sell $121 million worth of royal-related baby toys and souvenirs. Merchandise ranges from diaper covers and clothing to a “prince potty chair,” which of course is in the shape of a throne.
On Twitter, at least seven topics related to the royal baby jumped to the top of the trending list in the United Kingdom Monday morning. And “Kate Middleton” was trending in the United States.
Many tweets were along the lines of the comment of Holly Thrift, who wrote, “The royal baby is coming! I am freaking out!”
The baby was the only topic on the radio talk show hosted by Vanessa Feltz on BBC London 94.9 on Monday morning.
But not everyone was thrilled. Feltz read on air a message from “Gary” asking, “Please, please please, I implore you not to devote too much of the morning’s show to the royal baby.”
Feltz replied, “C’mon, Gary, give an inch. …. It’s huge, we can’t ignore it.”
She reported Gary sent another message: “OK, point taken. I’m a beaten man.”
