Prince William and his wife, Kate, the Duchess of Cambridge, are expecting their third child, Kensington Palace said Monday. The announcement came as the palace said that Kate was not feeling well enough to attend an engagement later in the day, reports the AP. As with her other two pregnancies, the duchess is suffering from Hyperemesis Gravidarum, or acute morning sickness; the condition forced the palace to announce Kate's two previous pregnancies before the 12-week mark, notes the BBC. "The queen and members of both families are delighted with the news," the palace said in a statement. Kate is being cared for at her Kensington Palace home in London. William and Kate, both 35, already have two children: Prince George, 4, and Princess Charlotte, 2. No details were immediately available about when the third baby is due.
The royals have said from the time of their engagement that they wanted to have a family — the only question was how many children they wished for. Royal watchers recorded every aside for clues as to what the plans might be. When asked on a royal tour in Singapore in 2012 about how many children he wanted, William said he was "thinking about having two." More recently, during a royal tour of Poland, Kate joked about a third child when given a cuddly toy designed to soothe tiny babies. Kate thanked the well-wisher for the present and turned to William. "We will just have to have more babies," she said laughing. Prince George is due to start school this week, notes the BBC's royal correspondent, and while "presumably his mother would be keen to take him to that, whether she is going to be well enough to do that remains to be seen."
