Kate Middleton due date July 13? Royal baby birth any day as Queen prepares travel arrangements for Prince William

Prince William said he and his wife wanted to use philanthropy as a "catalyst for meaningful change"PA

Kate Middleton is due to give birth to the first Prince or Princess of Cambridge any day.

The official due date is believed to be July 13, but the baby may make its way into the world any day as the betting odds continue to reach an all-time high, with punters betting on everything from the baby's sex and name to what University he/she will attend in the future.

The Royal Mint revealed last week that it will be making special edition silver coins in honor of Prince William and Kate Middleton's first child. These coins will be handed out to all babies born in Britain on the same day as the future Prince/Princess.

A high-speed helicopter has been put on standby so that Prince William can be flown from his RAF base to be by Middleton's side in London when she goes into labour. The Duke, who works as a rescue pilot in Anglesey, has reportedly promised to be by her side when the time comes.

Middleton is set to give birth at the private Lindo wing of St Mary's Hospital in Paddington – the same hospital where Prince William was born.

According to The Mirror, Prince William is prepared to be the modern father that his father Prince Charles never was. A source told the paper: "William will very much want to be a modern father. He has huge love for Kate and is adamant he'll be with her when she gives birth. Charles was there when William was born but he never changed a nappy – it just wasn't the done thing. But William is a generation on and the practicalities of fatherhood mean very ­different things to him. He'll expect to have sleepless nights and take a hand in changing nappies. He'll be very hands-on – and that means from Day One."

The Queen will be the first to receive the news of the birth of the baby. The news of the birth of the baby will first be reported to the Queen before any official announcement is made. An aide from the hospital will carry a piece of paper with details of the baby's gender, weight and time of birth, which will then be taken to Buckingham Palace. The official notice will be put on an easel on the forecourt of the Palace for the world to see before the Palace's official Twitter feed sends out the news.

The baby will be delivered by Queen Elizabeth's former gynecologist, Marcus Setchell, along with her current gynecologist, Alan Farthing.

The pair says they do not know the sex of the baby yet.

Possible royal baby name that have been circulating the web are: Alexandra, Diana, Elizabeth, Victoria, George, Andrew, Catherine, Charles and Alexander.
