The Duke and Duchess of Cambridge's baby is the first royal baby for 300 years to have a commoner for a mother and if William and Kate get their way, it won't have a typical royal upbringing at all.
It will begin the moment the new family leaves the hospital. Where other babes have headed straight to a royal palace, the Prince of Cambridge will spend its first six weeks in a common home.
Kate, William and their son will move in to Michael and Carole Middleton's middle class Berkshire home so Kate can be close to her own mother as she gets used to being a mum herself.
The trio will then return to Nottingham Cottage, the small two-bedroom house in the grounds of Kensington Palace where they have lived since their wedding in April 2011.
They won't be there for long however. The $1.5 million renovations on their new family home — Kensington Palace's 20-room Apartment 1A — are due to be complete in September or October.
The new family residence will be homely, not lavish, and include a large nursery for the baby and any other little ones that come along in years to come.
Kensington Palace holds lots of happy memories for William, who lived there with his mother until her death in 1997.
William and Kate will be keen to fill their new home with a lifetime of happy memories of their own and given how grounded and in love they obviously are, it's hard to see how they could fail.
