Duchess of Cambridge Kate Middleton and Prince William went to the Lindo wing just before 6 AM this morning Greenwich Standard Time.  A spokesperson for Kate Middleton and Prince William said: "Things are progressing as normal."

Prince William and Kate Middleton have not revealed the Royal Baby name, but contenders are reported to include Elizabeth, Phillip, and Alexandra.  Prince William and Kate Middleton have also not revealed the royal baby gender.  It is not known whether Prince William and Kate Middleton have chosen to know the royal baby gender.

Prince William's first call to the Queen will be via encrypted phone.  After Prince William has informed the Queen, the royal couple's private secretary will inform Prime Minister David Cameron, the Archbishop of Canterbury, and selected other individuals.  Officials will then notify the heads of state of commonwealth countries of the Royal Baby Birth.

Royal watchers must wait to be told of the baby's arrival from the palace.  The palace is planning to reveal the news through a mixture of tradition and social media.

Palace officials have said that the first hint will come when a royal aide emerges from the hospital with a signed bulletin carrying the Buckingham Palace letterhead. The bulletin will be given to an official who will be driven to Buckingham Palace, where it will be posted on an easel in public view in front of the building.

At the same time the bulletin is posted, there will be an official announcement on Twitter and the media will be formally notified. The document will contain the baby's gender, weight and time of birth.

The baby's gender that is of particular interest because the prospect of Kate's pregnancy prompted a change to laws of succession to ensure a daughter would not be passed over for the crown by a younger brother. Boy or girl, the child will be third in line to the throne and the prospective future monarch.

The Royal baby will be third in line for the British throne, and should eventually succeed grandfather Charles and father William as king or queen of Britain and 15 other countries including Canada and Australia.
