Like his father before him, Britain's Prince George is visiting Australia and New Zealand with his parents, Prince William and Kate Middleton, before turning 1 year old.

"Taking a 9-month-old on a royal tour is not a first, but it has not happened in this royal family's context for many, many years, so there has been much to think about -- as any new parents traveling long-distance will recognize," Miguel Head, the couple's private secretary, said in a statement Sunday, explaining, "The tour has been designed with Prince George's consideration and comfort in mind."

The prince was born July 22. The royal family is scheduled to arrive in Wellington, New Zealand, on April 7, and leave for home from Australia on April 25.

The trip will accommodate the young prince through a hub system, in which rather than traveling serially from place to place, William and Kate will return nearly every night to one of three hub cities: Wellington, and Sydney and Canberra, Australia. A nanny, whose name has not be released, will accompany the child.

The itinerary includes a war-memorial wreath-laying; visits to a children's hospice, military bases, the National Portrait Gallery and the National Arboretum; and a meeting with aboriginals at the National Indigenous Training Academy.
