The royal couple opted to go without a nurse when Prince George was born, but this time around they've decided to follow royal tradition.
George is now 18-months-old and although the couple have childcare help from housekeeper Antonella Fresolone, Kate and Wills are sure to welcome the extra pair of hands when their second child arrives.
The question is, will she live up to Antonella's high standard? The 42-year-old Italian has really raised the bar in the nanny stakes.
"Antonella has already been proving invaluable to the duke and duchess," a royal insider has revealed to the Express.
"She is very capable and a great cook. It's like having their very own domestic goddess.
"She made sure the Duchess was well fed during her pregnancy, cooking up steaming bowls of pasta and delicious risotto dishes. They couldn't do without her."
As Kate and Wills will have the odd royal engagement to attend once the royal baby is here, a full-time maternity nurse will definitely take the pressure off during the first three months.
And potentially avoid too many sleepless nights.
