Pregnant Princess Catherine is getting better

London: Pregnant Kate Middleton, the Duchess of Cambridge, was `feeling better` after spending a second day in hospital with acute morning sickness, palace officials said.

Prince William smiled with relief as he left his pregnant wife in the care of two top royal doctors and issued a statement last night saying Kate is `continuing to feel better`. Quoting sources, The daily Mail said the Duchess, 30, is responding well to treatment. The couple also said they are `immensely grateful for the good wishes they have received` as the Duke left the King Edward VII hospital in clear good spirits after spending hours at his wife`s bedside. A St James`s Palace spokesman said last night: "The Duchess of Cambridge is continuing to feel better. She and the Duke are immensely grateful for the good wishes they have received. She will remain in hospital at present and will continue to be treated for Hyperemesis Gravidarum." Duchess`s rare illness could mean she is expecting twins: Doctors reassure Wills and Kate that condition is not dangerous if treated (and could mean double baby joy). The name game has begun. Elizabeth already hot favourite as couple surprise the bookies with their early pregnancy announcement. New Royal baby will bump Uncle Harry into fourth place in the line of succession. Kate, 30, who is less than 12 weeks pregnant, has been on a drip to restore lost nutrients since being driven to the King Edward VII Hospital in central London by her husband yesterday. MailOnline sources today confirmed the Duchess is bearing up well - but her symptoms of severe vomiting may last for much of her pregnancy. She is likely to be taking anti-sickness tablets after developing the rare illness Hyperemesis Gravidarum that affects one in 50 women. PTI
