Royal Family reacts to the birth of Duchess Kate and Prince William's baby #3

Catherine, the Duchess of Cambridge, gave birth to a healthy baby boy in the Lindo Wing of St. Mary's Hospital in Paddington.

She went into labor shortly before 6 am on April 23, 2018, and the fifth in line to the throne made his appearance at 11:01 am, weighing 3.827 kilograms.

As reported by Royal Central, Queen Elizabeth II was the first to be informed of the birth, before the news was announced on Kensington Palace's official Twitter account.

Other members of the Royal Family were also informed, including the grandparents, Prince Charles and his wife, Camilla, the Duchess of Cornwall.

The news was shared with Prince Harry and with 'members of both families' as well. Kensington Palace confirmed that family members 'are delighted with the news.'

At 2:30 pm, a golden easel bearing a notice was placed on the forecourt of Buckingham Palace, marking the official announcement of the birth of Prince William's third child.

In addition, a large Union Flag was hoisted over the Palace an hour later, while a standard-size state flag was raised over Windsor Castle to mark the joyous occasion.

Prince William was seen leaving St. Mary Hospital, and Kensington Palace's administration tweeted that he had to attend to Prince George and Princess Charlotte, who remained at home.

He returned to the hospital at 16:50 pm, with Prince George and Princess Charlotte in tow. All three wore shades of blue as they walked up the steps of the Lindo wing.

They only visited their mother and baby brother briefly, before returning to Kensington Palace, while the Duke stayed behind at the hospital.

According to Kensington Palace's Twitter account, the Duke and Duchess will return home later this evening, with their newborn son.

His name will only be announced in the coming days. The Sun reported that the name Arthur has odds of 7/4, while James had 5/1 and Philip 6/1.
