Just seven hours after giving birth to her third child, Kate Middleton appeared (in heels!) on the steps of the Lindo Wing at St. Mary’s Hospital on Monday evening with Prince William by her side to introduce their new baby boy to the world.
The royal baby was wrapped in a white shawl (from royal favorite brand GH Hurt and Son Ltd) in his mother’s arms as he was presented to the enthusiastic crowds of well-wishers who gathered outside the hospital, anxiously awaiting a peek at the newborn prince.
Kate looked stunning in a red dress with a white collar (almost identical to the dress Princess Diana wore after giving birth to Prince Harry) by Jenny Packham (shop similar looks here and here) after a visit from her go-to stylist, Natasha Archer, who was spotted leaving the Lindo Wing an hour before the royal gave birth. She paired the look with nude suede heels.

A group of devoted royal fans have been camped outside the hospital since April 9 in anticipation of the royal baby’s birth. Terry Hutt, 83, and John Loughrey, 63, are among the supporters who have a clear view of the famous door to the Lindo Wing, where Will and Kate will debut the royal baby.

“I had a sense it was going to be today,” he says.

The soon-to-be mother of three first announced her pregnancy in September in a statement from the palace.
“Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their third child,” the statement read. “The Queen and members of both families are delighted with the news.”

Just like her previous pregnancies, Kate suffered from Hyperemesis Gravidarum during her first trimester, which led her to miss Prince George’s first day of school. But she resumed her royal duties by her second trimester, keeping up a busy schedule until the weeks leading up to the birth. At an event in February, Kate joked that William was “in denial” ahead of the arrival of their third child.

Kate gave birth to daughter Charlotte in May 2015 only two-and-a-half hours after being admitted to the hospital. And just 10 hours after she gave birth, she appeared on the hospital steps looking stunning as she introduced the baby princess to the world.
The arrival of Will and Kate’s third child could be historic: If the baby is a boy, he will not displace big sister Charlotte in the line of succession, thanks to a measure that passed just after Will and Kate’s 2011 wedding. Up until this change, a younger son would usurp his older sister’s place when it comes to inheriting the throne.
THE Duke and Duchess of Cambridge beamed with joy as they introduced their baby boy to the country and the world.
William and Kate left St Mary's Hospital with their new arrival after posing for pictures on the steps of the Lindo Wing.

KATE Middleton gave birth to her third child on April 23, 2018.
But these are the unusual royal birthing rules that the Duchess of Cambridge had to follow in order to adhere to tradition. Here's the lowdown...
Getty - Contributor Kate Middleton has given birth to her third child - a baby boy
The royal family has a set of customs they follow when any baby is born – including who the first person to be told the news is.
Other practices dictate who is allowed in the birthing room and how the birth is announced to the British public.
1. The Queen has to be the first to know
The Queen must be told a child has been born into the royal family before the news is announced publicly.
It's reported that Prince William rang his grandmother on an encrypted phone when Prince George was born.
Traditionally, the announcement has always been on an easel outside Buckingham Palace.
Kate and William broke this protocol and announced it on Twitter with Prince George.

2. The town crier announces the news to the public
Town crier Tony Appleton announced the births of both Prince George and Princess Charlotte.
This custom harks back to medieval times when people couldn’t read or write.
3. Home births are preferred
As is tradition, the Queen gave birth to all of her children in Buckingham Palace.
Princess Diana broke this rule and gave birth to sons Prince Harry and Prince William at London’s St. Mary’s Hospital in the private Lindo Wing.
Kate also had her three children at this hospital.

4. Dads are banned from the birthing room
Giving birth is considered a female-only event and fathers are not allowed in the delivery room.
This rule is believed to have been relaxed after the birth of Prince Charles.
