Britain's Duchess of Cambridge had a medical team "on call for three months" before the births of her two children.
The brunette beauty, 34 - who is married to the Duke of Cambridge, 31 - had 23 Imperial College Healthcare specialists supporting her at London's St. Mary's Hospital in 2013 and 2015 when she was pregnant with Prince George, now aged two, and 12-month-old Princess Charlotte.
The group were invited to a Buckingham Palace garden party on Tuesday (24.05.16) and greeted by the royals and Catherine's anesthesiologist, Dr. Johanna Bray, also revealed details of the huge work commitment but said it was a "wonderful" experience.
She said: "(We) were behind the scenes. We were all on call for three months - my husband did the childcare for three months! You never know when you need to be called. You need to be in town and available. If you are at a party you need to have your car keys at the ready. No drinking!
"There were about 20 of us that would regularly meet to discuss things. It was a wonderful feeling... it was a real morale booster for St. Mary's at the time.
Professor Tiong Ghee Teoh was a consultant obstetrician and gynecologist in the team and added their top priority was to be able to fix any problems should anything go wrong.
He added: "We had a huge team. Anything that could possibly go wrong, we had a team of people behind each specialty. Everyone was sworn to secrecy."
And Catherine suffered from the condition Hyperemesis Gravidarum - which can leave a woman bedbound or need to be admitted to hospital due to extreme dehydration - during both her pregnancies but had no idea her support network during those delicate months was so big.
He said: "(Catherine) was very appreciative. She said there were a lot more people behind the scenes than she realized."
