The Duke and Duchess of Cambridge are expecting their baby in April. 

Kensington Palace said the couple were “delighted” to confirm the month their third child is due to be born. 

The duchess has been suffering from hyperemesis gravidarum - a severe form of morning sickness - but made a surprise appearance at a royal engagement on Monday, and is due to visit Norway and Sweden with the duke on an official visit early in 2018.
