It used to be custom for royal mothers to give birth inside royal residences, but times have now changed, with the likes of Princess Kate, Duchess Meghan and sisters Princess Beatrice and Princess Eugenie welcoming their babies in hospital.
The late Queen's daughter, Princess Anne, was a trailblazing royal as she was one of the first royal mothers to break the tradition of home birth - delivering both of her children, Zara Tindall and Peter Phillips at St Mary's Hospital in Paddington, London.

Royal home births were originally part of a long line of traditions that saw royal ladies go into 'hiding' in the late stages of their pregnancy, as birth was seen as a strictly private experience.
However, after Princess Anne's hospital births, the late Princess Diana, and more royal mothers followed suit, also opting for hospital births.
Princess Anne was the first British royal to give birth in a hospital
Read on to find out how Princess Anne delivered her two children…
Princess Anne's birth of Peter Phillips
The Princess Royal's eldest child, Peter Phillips, was born at 10:46 am on 15 November 1977, in the Lindo Wing of St Mary's Hospital.
According to BBC's On This Day, Princess Anne was driven to the hospital in Paddington at 4 am by her then-husband, Captain Mark Phillips, and Peter was born less than six hours later in the Lindo Wing, weighing 7lb 9oz.
As Anne was the only daughter of the Queen and Prince Philip, her children weren't guaranteed a royal title – unlike the children of the monarch's male offspring. However, the Queen still offered courtesy titles to both Mark when he married Anne, and their children, which the Princess declined.
