Information about the births of all the late Queen Elizabeth’s children. Some medical authorities in Britain certainly seemed to be fans of the ‘twilight sleep’ procedures.

About Charles ….. apparently the Queen was in labour for about 30 hours and nothing was happening. A bit like the QM before her. So a c-section was decided upon.
‘Eventually Charles was born by a Caesarean section in a music room in Buckingham Palace which had been converted into a theatre. She was attended by Obstetricians Sir William Gilliatt and Sir John Peel, and also midwife Helen Rowe, who was thought to be present for all the births. Caesarean sections were also less common in the general public at that time; in the 1950s only around 3% were caesarean section. It would have been of some concern that the Queen required one. It is known Prince Philip was not present for this birth, playing squash with his private secretary until he received the news. It was usual for partners to not be present during labour and birth; it was not until 1960s that this became more accepted.’
