Kate Middleton may give birth to her first child any day as she is reportedly overdue.

The supposed due date for Kate Middleton and Prince William's was July 13 and the royal baby is now two days overdue.

The royal baby watch is at fever pitch amid the scorching heat wave that is sweeping across the UK.

Us Weekly reported that the Duchess of Cambridge went to her parent's house in Bucklebury to escape the heat. Prince William was also spotted playing polo over the weekend.

Many speculate that the royal baby will be born today, or by latest Wednesday.

Reports suggest that doctors may consider inducing Middleton into labour now that the due date has passed.

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. Media and royal fans have been camping outside the hospital to catch a glimpse of the Duchess making her way into the hospital when she goes into labour.

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 Duke and Duchess of Cambridge do not know the sex of the baby.
