On April 23, 2018, Prince William and Kate Middleton welcomed royal baby number three! Here are the best photos of the baby's debut – as well as the most precious moments as the royal couple introduced their first two children, Prince George and Princess Charlotte, after their births at the exclusive Lindo Wing of London's St Mary's Hospital. MEET BABY CAMBRIDGE #3! The evening of April 23, Prince William and Duchess Kate emerged with their new bouncing baby boy, whose name has not yet been announced.

THE HEIR IS HERE! It was the moment royal watchers had been waiting for – with proud mother Kate Middleton by his side, Prince William introduced his firstborn child Prince George to the world outside the Lindo Wing. The beautiful boy, third in line to the throne, was delivered at 4:24pm on July 22, 2013 at St Mary's Hospital, and William and Kate greeted the press as they left with him on the following day.

Upon the arrival of the little boy – whose name would later be confirmed as Prince George Alexander Louis of Cambridge – Kensington Palace released a statement. It read: "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. Her Royal Highness and her child are both doing well." Photo: Getty Images

New parents William and Kate spoke to the huge crowd of press and well-wishers who had gathered outside the Lindo Wing in anticipation of George's big debut. Photo: Getty Images

"We could not be happier," said first-time dad the Duke of Cambridge, who was at his wife's side when she gave birth. Also thrilled was new grandfather Prince Charles. "Both my wife and I are overjoyed at the arrival of my first grandchild," the Prince of Wales said. "Grandparenthood is a unique moment in anyone's life, as countless kind people have told me in recent months, so I am enormously proud and happy to be a grandfather for the first time."

Kate, wearing Jenny Packham, laughed as new dad William relayed an anecdote. An ecstatic Prince William had called the Queen to break the news that she was a great-grandmother, and that a future King had been born. Prince George is third-in-line to the throne and the Queen's first great-grandson. Photo: Getty Images

The day old little Prince had managed to sleep peacefully through his first time in front of the press. Little did he know he would return to the Lindo Wing in 2015 to meet his little sister! Photo: Getty Images

HELLO, LITTLE PRINCESS! The world gained a new Princess after the Duchess of Cambridge gave birth to her second child Princess Charlotte with Prince William by her side. Prince George's little sister was born on May 2, 2015 at 8:34 am in the exclusive Lindo Wing of St Mary's Hospital, London. The baby royal weighed in at 8lbs 3oz – and made her public debut just 10 hours after her birth! Photo: Getty Images

William and Kate – who again chose Jenny Packham for her leaving the hospital look – looked thrilled as they walked down the steps of the Lindo Wing hand in hand with their new baby in tow. Photo: Getty Images

When the couple emerged with their new daughter, we got the very first close-up of Princess Charlotte as she made her debut! The Princess was the first girl to have been born to a direct heir to the throne since the Queen gave birth to Princess Anne 64 years earlier. Photo: Getty Images

The little girl's name would later be revealed as Princess Charlotte Elizabeth Diana of Cambridge – with one of her middle names dedicated to her late grandmother, Princess Diana. In this photo, Charlotte co-stars in the shot with her mom's sapphire engagement ring, which once belonged to Prince William's beloved mother. Photo: Getty Images

One of the sweetest moments of the day was when Prince George arrived at the Lindo Wing to meet his baby sister for the very first time. Shortly after 4pm, the little royal arrived with his proud father Prince William to be introduced to the newborn Princess of Cambridge. Photo: Getty Images

Dressed in a nearly identical outfit as his son, William paused briefly outside the doors to the Lindo Wing, talking to George all the while to reassure the little boy. He then gave his son a tender kiss before heading into the hospital to start their new chapter as a family of four. Photo: Getty Images
