The Queen suffered post-natal side effects after giving birth to Andrew having used the now discredited Dammerschlaf technique for the delivery of her first three children, a new book claims.
It tells of how the late Queen showed considerable stoicism in her later years as she suffered deteriorating health and yet continued to keep herself busy until the end.
But it has also given a rare insight into the details over the births of her children which are normally kept private, with the book by Gyles Brandreth giving some surprise information about the deliveries.
