Prince Harry and Meghan recently announced via a statement from the Palace that they will shun the royal tradition of a delivery at the Lindo Wing of St Mary's Hospital in London.
The Sussexes will also skip the trademark photo call immediately following the birth in favour of a press shoot in the grounds of Windsor Castle some time after when both Meghan and Baby Sussex are settled and comfortable.
Another rule Harry and Meghan are foregoing is the practice of giving their child a royal title.

The alternative arrangements favoured by the couple have been taken as even more signs of a rift between Harry and Meghan and the Cambridges, who adhered to protocol with each of their children, Princes George and Louis and Princess Charlotte.
Prince Louis, the youngest child of Prince William and Kate Middleton, celebrates his first birthday today.
To mark the occasion, Kensington Palace treated royal enthusiasts to a stunning series of new photos of the little Prince.
