Prince William and Kate Middleton have been dealing with pregnancy sickness since it was announced that they are expecting a sibling for Prince George.

The Duchess of Cambridge has been feeling unwell, suffering from extreme morning sickness (Hyperemesis Gravidarum) that has forced her to stay in to recuperate at the home of her parents in Bucklebury, about 55 miles west of London.

People.com reports that the Queen had given her all the time she needed to decide if she would be able to travel. The Duchess was asked by the Queen to go to Malta, on her behalf, to join the celebrations marking the island’s 50th anniversary of independence.

After consulting with her doctors, Prince William and Kate were initially set to make decision on whether to travel on Wednesday. The date was then pushed back to Thursday, but now it turns out that Prince William will take over for his sick wife. The report said that the Duchess was very keen on going to Malta but was advised by her doctors to stay home.

Prince Charles apparently hopes the new baby will be a girl. “It’s wonderful to be a grandfather again. I’m looking forward to it – but I hope it will be a girl this time,” said Prince Charles, as reported by Independent.

Reportedly,  Prince Harry wants the baby to be a girl as well, but for different reasons. “I can’t wait to see my brother suffer more,” he said. “I would love to see him try and cope with [a girl].”
