It seems the world has been watching for news of a baby almost since Britain's Prince William married Kate Middleton last year.

Speculation about Middleton possibly being in the family way has been rampant. Headlines were generated when Middleton declined to eat peanut paste, when she posed for pictures while holding her purse on front of her stomach, and when the royal pair decided to move into a larger home.

People magazine has devoted the cover of its latest issue to the topic, citing palace sources in reporting that the couple has put plans for an upcoming trip to Africa on hold because the vaccinations Middleton would need are dangerous for a fetus.

There's no official word from the Buckingham Palace that Middleton, 30, is pregnant, but the royal couple - to celebrate their first wedding anniversary on Sunday - generated other baby news when they were photographed Thursday admiring a 3-week-old at a party in London.

Royal watchers said the pair's demeanor with the infant indicated they would make great parents when the time comes.

Prince William, 29, held the baby, Hugo Eric Scott Vicary, and told the boy's father, Vic Vicary: "He looks very sweet," People reported.

Vicary described the prince as a "natural" with the baby, according to the magazine.

Middleton said the baby was very cute, Vicary told People.
