And while we'll all be eagerly anticipating a first glimpse of the little boy or girl when it arrives, there's one person who'll be lucky enough to be there to get to know them from the off - the new Royal baby nurse.
The Mail Online reports Kate and William have plans to hire a nurse to help them through the baby's early stages rather than relying on help from friends and family as they did with Prince George.
A source told the tabloid: "It was really hard work with George and there were lots of sleepless nights, so Kate has said she's going to have help with the next one."
We're pretty sure every nanny in the land is going to be after this gig, especially if the new addition is anywhere near as cute as gorgeous George!
In the lead up to the baby's birth poor Kate is suffering with chronic morning sickness and it's likely she'll have to cancel a number of official and social engagements as a result, including her first solo Royal tour of Malta.
"The likelihood is that Kate is not going to be up to the trip," a source told Vanity Fair. A spokesperson for Kensington Palace added, "We will be planning this on a case by case basis."
Clarence House are yet to disclose how far along Kate is in her pregnancy, but they have said they will disclose her due date when she reaches the three month stage.
