"There'll be a little bit of time when they get to know the baby. A little bit of downtime," an aide tells PEOPLE.
But the new mom and dad aren't facing their new roles alone – Pippa Middleton and boyfriend Nico Jackson have already been to Kensington Palace to help take care of the newborn and help the Duke and Duchess settle in, the aide adds.
And while there is currently no nanny in the household (a housekeeper and an orderly who helps with driving and general duties are the only domestic staff), "[Their] families will help them and the excellent advice they've had at the hospital," a royal source says.
But a friend says that will likely change. "It goes with the territory as it'll be a very short time before [Kate] goes back to her public duties," a friend tells PEOPLE.
Meanwhile, the couple have asked the public, in lieu of gifts, to donate to the charity of the hospital where Baby Cambridge was born.
In a message on their website, the Duke and Duchess thank well-wishers for their generosity and suggest "you could look to support Imperial College Healthcare Charity … [helping] women, their newborn babies and young families from London, across the U.K. and beyond to benefit from the latest research to ensure they receive the best possible care."
