KATE Windsor – the Duchess of Cambridge – is responding well to treatment for severe pregnancy sickness after spending a second day in hospital, St James's Palace has said.
A spokesperson said she was "continuing to feel better" and was "immensely grateful" for the messages of support she had received since being admitted on Monday.
Her improvement was reflected in Prince William's expression as he left the King Edward VII Hospital in London yesterday wearing a broad smile after spending almost six-and-a-half hours at his wife's bedside.
Bookmakers have slashed the odds on the duchess giving birth to twins from 50/1 to 8/1 after it was reported yesterday that her medical condition was associated with a threefold increase in a mother having twins.
Betting on the duchess giving birth to a girl may also increase after it emerged that the duchess's illness and lifestyle factors make her statistically more likely to have a daughter.
The odds on triplets, meanwhile, have come down from 1,000/1 to 100/1.
Surprisingly, punters have also placed money on the baby being called Wayne or Chardonnay, both at 500/1.
The bookmaker also said it had taken "hundreds of pounds" on the baby having ginger hair, like its uncle, Prince Harry, at odds of 6/1.
Kate is still expected to spend several more days in hospital, where she is thought to have been put on a drip to prevent dehydration after being diagnosed with hyperemesis gravidarum, which causes repeated vomiting.
A St James's Palace spokesman said: "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."
The duchess is being seen by Queen Elizabeth's former gynaecologist, Marcus Setchell, though the current queen's gynaecologist, Alan Farthing, the former fiance of Jill Dando, was also at the hospital yesterday, where he is thought to have been consulted on the duchess's treatment.
The duke (30) arrived at the hospital in a green Land Rover Discovery at 11.30am wearing an open-necked shirt, jumper, jeans and trainers.
He walked straight inside, without glancing at the scores of journalists and television crews from around the world gathered on the other side of the street. When he left shortly after 5.45pm there was a noticeable difference in his mood, and he made no attempt to hide his apparent relief at his wife's improvement.
Kate did not receive any other visitors, though her parents and siblings are expected to travel to the hospital from their home in Bucklebury, Berks, today. (© Daily Telegraph, London)
