Britain’s Prince William says he and wife Kate are happy about the pregnancy, but not looking forward to another royal baby mania.

The baby will be fourth-in-line to the British throne, after grandfather Prince Charles, father William and elder brother George, the couple’s first child born in July last year. There is no mention of when the new baby is due. The announcement was made on Sept 8 after Kate was forced to pull out of an official engagement at the University of Oxford because she was feeling unwell.

“We’re mostly thrilled, it’s great news, early days but I’m hoping that things settle down, she feels a bit better,” Prince William tells reporters on the visit. “She’s feeling ok, it’s been a tricky few days, week or so. I’m going to go back and look after her now.”

Buckingham Palace says Queen Elizabeth and both the royal and Kate’s families are delighted.

William’s office says Kate, 32, is suffering from hyperemesis gravidarum, an acute morning sickness which causes severe nausea and vomiting and requires supplementary hydration and nutrients, a condition that led to her hospitalization in the early months of pregnancy with her first child.

A spokeswoman says Kate has not needed hospital treatment this time, but is under the care of doctors at Kensington Palace, the couple’s London residence. Her future engagements, including her first solo overseas trip to Malta, will be reviewed on a case-by-case basis.
