It seems that the much awaited royal arrival is showing no signs of making his / her grand entrance, quite yet.

While all eyes are on the Lindo wing, in anticipation of the birth of the fourth-in-line to the throne, it seems local officials think it could be something of a wait for Kate yet.

The Duchess of Cambridge is already five days over her delivery date. While the royals had not revealed the official due date, it was predicted that she would give birth around 24 April.

Now, as the wait for the royal baby continues, in an indication that it could be some time yet, parking restrictions have been extended outside the private unit of St Mary's Hospital in Paddington, London, where the Duchess of Cambridge is due to deliver her second child.

The restrictions began on April 15 and were due to run out on April 30. They will now end on May 5. The yellow notices cite 'Special Event' as the reason for the suspension in front of the exclusive Lindo Wing.

A spokesman for the Westminster City Council said: "The parking restrictions will be extended at the moment for the next five days until May 5. If there is still no news by then it will be extended again. The signs will be amended possibly today, if not tomorrow morning."

It was hoped that the royal baby would arrive today, on April 29, the day of the couple's fourth wedding anniversary, making for a double celebration.

And it seems the Duchess of Cambridge is also keen for the baby to show itself. The Princess, who was once dubbed 'Wait-y Katie,' was spotted driving herself into Buckingham Palace this morning, for a swimming session in the Palace pool. Its thought swimming can have the effect of stimulating labour.

The fact that the Duchess is still going about her day-to-day routine at such a late stage in her pregnancy has added to speculation that she is likely to be induced.

Although some expectant mothers can wait up to two weeks after their delivery date, before being induced, medical experts have suggested that the Duchesses consultants – led by Surgeon-Gynecologist to the Royal Household Guy Thorpe-Beeston –probably won't wait for much more than a week before inducing labour.

Meanwhile, the Duke and Duchess haven't forgotten the royal super-fans, who have been camped outside the Lindo wing all this time.

The large crowd, who have braved all kinds of weather in the hope of being the first to share in the happy news, were treated to a special delivery of coffee and pastries from the Cambridges yesterday.

The town of Paddington are also bracing themselves for the imminent arrival and will adorn the streets lining Praed Street where St Mary's Hospital is situated, with appropriate coloured bunting - either pink or blue.

In a break with tradition, the birth of the royal will be announced on Twitter, but in Paddington a town crier will ring out the happy news. Tony Appleton - president of the Guild of International Millennium Town Criers - will announce the birth and call on residents to come outside and 'wet' the baby's head.

The Hilton London Paddington Hotel will also be lit up in the appropriate colour for a boy or girl as part of the local community's celebrations.

Kay Buxton, chief executive officer of PaddingtonNow, said: "Paddington is no stranger to welcoming royals, whether via the famous rail station, in a procession through Sussex Gardens or, of course, at St Mary's Hospital, and it's thrilling to be the host of the activity once more this year to welcome the new prince or princess.

"The arrival of Prince George saw all eyes on the area and as excitement builds for the next arrival, we're bringing together the community across the area to welcome him or her with a grand celebration on Praed Street."

Royal biographer Christopher Wilson said: "It's time to rename it the Royal Borough of Paddington.

While the public are ready to celebrate, and the world waits for news, and even the future King and Queen are growing impatient, it seems this royal baby knows just how to make an entrance.
