While the Duchess of Cambridge won't be heading back to the hospital this time, Prince William reportedly canceled his appearance at the British Military Tournament Sunday to be by her side at Kensington Palace as she recovers, a rep for the royals confirms to E! News.
"The Duke of Cambridge will no longer attend the British Military Tournament at Earl's Court this evening," the rep said in a statement. "But will spend Sunday privately with the Duchess instead."
"It is well known that hyperemesis gravidarum often recurs and, until further notice, to allow the Duchess a degree of privacy during her pregnancy, we do not intend to offer regular condition checks or advise of routine developments associated with it."
Saturday, Prince William commented about his wife's health to former Centrepoint chariman Michael O'Higgins at the Winter Whites Gala, saying "I don't know why they call it morning sickness—they should call it all day and all night sickness. It's a long old process but she is getting there. She feels like it is going to go on forever," according to Gossip Cop.
After announcing her pregnancy Monday, Middleton was admitted to the UK hospital for treatment for this acute form of morning sickness and was released Thursday.
