In October, Kensington Palace announced the third baby would be born in April 2018. On Sept. 4, the couple announced the Duchess of Cambridge was pregnant and suffering from acute morning sickness, also known as Hyperemesis Gravidarum.
The baby's expected due date was revealed hours after Kensington Palace announced the Duke and Duchess of Cambridge would be making an official visit to Norway and Sweden in early 2018, at the request of the United Kingdom's Foreign and Commonwealth Office.
Dr. Alan Farthing and Dr. Guy Thorpe-Beeston presided over all three of Middleton's births. Farthing is Queen Elizabeth II's surgeon-gynecologist and obstetrician Thorpe-Beeston specializes in high-risk pregnancies.
Queen Elizabeth is the longest-reigning monarch in British history. The monarch has ruled the United Kingdom for more than 66 years. Just a few short days ago, Prince Charles was named Commonwealth Leader after being endorsed by his mother.
The 91-year-old monarch made her comments at the formal opening of the Commonwealth Heads of Government Meeting, which took place in Buckingham Palace.
"It is my sincere wish that the Commonwealth will continue to offer stability and continuity for future generations and will decide that one day, the Prince of Wales should carry on the important work started by my father in 1949," she said at the meeting. "By continuing to treasure and reinvigorate our associations and activities, I believe we will secure a safer, more prosperous and sustainable world for those who follow us."
Kate Middleton and Prince William's latest addition to the royal family marks the Queen's sixth great-grandchild. Congratulations to all on the exciting baby news!
