Prince George's birth

St James' Palace announced that William and Kate were expecting their first child on 3 December 2012. The exciting news came early in her pregnancy due to Kate being unwell with hyperemesis gravidarum and requiring hospital treatment. Fortunately, the Duchess felt better in the final trimester and the world celebrated with the royal couple when little Prince George arrived at 4.24pm on 22 July 2013.

William had the duty of calling his grandmother, the Queen, on a specially encrypted phone to tell her the happy news. Then he called Kate's parents, Carole and Michael Middleton, in Bucklebury, her sister Pippa and brother, James, his own father Prince Charles and his brother Prince Harry. The couple waited one day before leaving hospital with their baby boy.

In 2017, doctors from Kate's healthcare team shared some details of the pregnancy and birth. Professor Tiong Ghee Teoh, a consultant obstetrician and gynaecologist, and anesthesiologist Dr. Johanna Bray were a part of the royal's 23-member medical team that were on call three months prior to the birth in case extra assistance was required.

"We had a huge team,” Professor Teoh revealed. "Anything that could possibly go wrong, we had a team of people behind each speciality.” He added, "Everyone was sworn to secrecy.” The Duchess of Cambridge’s Imperial College Healthcare team included two obstetricians, three midwives, three anaesthetists, four surgical staff members, two special care baby-unit staff, four paediatricians, one lab technician and three to four managers.

Princess Charlotte's birth

The world learnt of Kate's pregnancy with Princess Charlotte on 8 September 2014. A statement read: "Their Royal Highnesses the Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their second child. The Queen and members of both families are delighted with the news.
