Kate Middleton's third pregnancy was announced last month as she was suffering from severe morning sickness once again.
But now that the Duchess of Cambridge is officially three months along, Kensington Palace have announced that the baby is due next April.
The royal family were forced to confirm Kate's pregnancy earlier than usual, as she was suffering from hyperemesis gravidarum as she did with her previous two pregnancies.

After an initial announcement was made on 4 September, the news was today confirmed by the Kensington Palace official Twitter account, who posted: "The Duke and Duchess of Cambridge are delighted to confirm they are expecting a baby in April 2018."
Congratulations to the family!
This comes a day after Wills and Kate were spotted meeting the cast and crew of upcoming film Paddington 2, starring Downton Abbey's Hugh Bonneville, Julie Walters and Hugh Grant.
Prince Harry was also there, and shook a mascot Paddington's hand - what a good sport!
There was just a HINT of a baby bump on show, as Duchess Catherine appeared to keep her bag in front of her tummy at all times.
Whilst Kate could be seen holding her hand protectively over her tummy in a lot of the photos, she got into the spirit of things and could be seen dancing along with the mascot dressed up as Paddington.
The newest baby will be fifth in line to the throne, below Prince Charles, Prince William, Prince George and Princess Charlotte.
They will overtake their uncle Harry, who is currently in the fifth slot.
Paddy Power have the names Alice, Victoria, Arthur, Henry and Elizabeth as their top five names, with Mary, Alexandra, Frederick, Albert and Grace following to make up the top 10.
At 20/1 is Diana - as is Catherine, with William at 25/1.
What do YOU think the Royal Baby will be called? Let us know over on Facebook and Twitter.

Bink's red carpet debut is miles away from her current aesthetic - which is very 'glowy, yummy mummy who is perennially sipping kale juice'.
