The Duke and Duchess of Cambridge are expecting their second child
The Queen and members of both families are delighted with the news.
As with her first pregnancy, The Duchess is suffering from Hyperemesis Gravidarum. Her Royal Highness will no longer accompany The Duke of Cambridge on their planned engagement in Oxford today. The Duchess is being treated by doctors at Kensington Palace.
-- Hyperemesis Gravidarum is very acute morning sickness, which may require supplementary hydration, medication and nutrients.
