Kate has come down with another bout of acute morning sickness, just days after the Duchess checked out of King Edward VII hospital.
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, according to Us Weekly.

"It is well known that Hyperemesis Gravidarum often recurs," a St. James Palace spokesman told the mag, using the medical term for this type of morning sickness.
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.
