LONDON (CBSNewYork/AP) – From a royal wedding to a royal arrival.

The Royal Palace announced Monday that Prince William and Kate Middleton, the Duchess of Cambridge, are expecting a child.

But even for royalty, pregnancy is not without its complications. Middleton was admitted to a hospital in London today due to acute morning sickness.

“As the pregnancy is in its very early stages, Her Royal Highness is expected to stay in hospital for several days and will require a period of rest thereafter,” the Palace said in a statement.

Ever since their storybook wedding at Westminster Abbey in 2011, royal watchers had been asking the question:  When will the couple start their family?

As the first born to William — who is second in line to the throne after his father, Prince Charles — the couple’s first child stands an excellent chance of one day becoming monarch.

Whether boy or girl, the child will be behind Prince William in the line of succession to the throne, Cabinet Office officials said.

The royal couple’s pregnancy news had many people on both sides of the pond, from Westminster to the West Village, excited.

Nicky Perry, owner of Tea and Sympathy on Greenwich Avenue, threw a block party to celebrate the royal wedding and now she’s planning a baby shower.

“I’m going to blend all your food and you can all have baby food for the day,” Perry joked. “I don’t know how fish and chips is going to work in a blender.”

Customers were also delighted by the big announcement.

“I think it’s amazing, I’m glad,” customer Hayley Simmons said. “That means we get another big holiday, right? Well, over there.”
