All eyes are on the Lindo Wing of St. Mary's Hospital in Paddington as we wait for Kate Middleton to give birth to her second child with husband Prince William.

The Duchess of Cambridge went past her mid-April due date setting off the "Great Kate Wait" as people anxiously wait for the royal baby to arrive, The Telegraph reports.

Whitehall sources confirmed Kate Middleton is more than a week overdue because the baby, who is fourth in line to the throne, was expected to arrive on April 23.

Meanwhile, other sources say she was due on April 25. Either way, doctors have up to two weeks after the due date to induce labor.

A source whose children were born at the Lindo Wing said doctors usually don't wait more than a week to induce labor enticing people to believe that the baby would be born Friday evening. It is not unusual for the Duchess to give birth late since Prince George was born after his due date in July 2013. Prince George was born by a natural delivery, so it is expected that the next baby will too.

Prince William has been dividing his time between Staverton in Gloucestershire, Cambridge and Norwich as they wait for the baby to arrive while he was completing his air ambulance pilot training.

The Duke of Cambridge has completed his training as we approach the finals days of Middleton's pregnancy and is expected to be present during the birth.

One of the best medical teams led by Guy Thorpe-Beeston, Surgeon Gynaecologist to the Royal Household, is in charge of safely delivering the baby.

The sex of the baby has not been released but many people are convinced the new royal baby will be a girl, according to The Telegraph.

Up to 90 percent of all bets are on the possibility of a girl since the Duchess of Cambridge has been wearing a lot of pink during her pregnancy, and Prince William previously said he wanted a daughter.
