The relief was evident on William’s face when he finally left the hospital.
The Duke of Cambridge is “immensely grateful for the good wishes they have received,” his spokesman said.
Queen Elizabeth and the rest of the royals found out later Monday after William and Kate raced to the hospital, where the stricken princess was diagnosed with hyperemesis gravidarum, a malady that affects one in 50 expectant mothers and can turn pregnancy into torture.
Citing royal sources, the Daily Mail reported the Duchess of Cambridge was holding her own “but her symptoms of severe vomiting may last for much of her pregnancy.”
Kate, who is 30 and believed to be about 12 weeks pregnant, was expected to remain in the hospital for several more days followed by a “period of rest” at home. She is reportedly on an IV drip to combat her dehydration and taking pills to stop the nausea.
“When this occurs, the simple treatment is to get fluids into them — and usually they feel considerably better,” Dr. Peter Bowen-Simpkins, medical director at London Women's Clinic, told the BBC.
Easy for doctors to say; they’re not the ones getting sick, HG survivors told The Daily News.
“If Kate's back in circulation by the second trimester, I'll be very impressed,” said Lucinda Herbert Flynn of Westchester, who was sick for duration of both her pregnancies.
Carole Middleton leaves her home in Berkshire, England on Tuesday.
“I remember being so weak I would simply lie on the bathroom floor — vomiting seven or eight times per day — even in labor,” the mother of two wrote. “Each time, I was hospitalized for a week and hydrated intravenously.”
Another mother of two, who wished to remain anonymous, wrote that she was laid low by the illness during both her pregnancies and what she “experienced the second time can only be described as hell on earth!”
“Not only was I robbed of any joy in anticipating the arrival of a new life — I was robbed of the joy of more children,” said the 31-year-old mom, who underwent a tubal ligation rather than risk getting pregnant again.
William, 30, is second in line for the throne after his father, Prince Charles. Under new rules, William’s first child — whether a boy or a girl — would be third in line to become monarch.
The baby would be the first grandchild for Charles and the third great-grandchild of Queen Elizabeth.
The intense speculation about when the Duke and Duchess of Cambridge might have a child began shortly after they tied the knot on April 29, 2011.
Now oddsmakers are betting that they royals will name their first firstborn John or Charles if it’s a boy, Elizabeth or Diana if it’s a girl.
William’s mother was the late Princess Diana.
While the rest of the Royal-watching population have spent the past few days focused on Kate’s extreme morning sickness, London’s super-rich Moms have been busily speculating about where the royal tot will be born.
