Kensington Palace has formally announced that royal couple William and Kate are expecting their third child.

The Royal family had to announce the news early on in the Duchess’s pregnancy as she’s suffering from severe morning sickness (hyperemesis gravidarum), as she did in her previous two pregnancies, forcing her to cancel all royal engagements. The condition affects one in approximately every 200 pregnancies, causing severe nausea and vomiting.

William and Kate have two children: George, aged 4, and Charlotte, 2.
