Unless William and Kate's second child arrives on 30 April, the couple look set to have a May-born baby. While Kate had previously said that her due date was around "mid-to-end of April" during a London-based engagement in March, it would appear that the little royal isn't ready to make his or her way into the world just yet.
On Wednesday Westminster Council extended parking restrictions outside St Mary's Hospital in Paddington where the Duchess, née Kate Middleton, is due to give birth.

William and Kate to set to have a May-born baby
Parking around the Lindo Wing had initially been off limits until 30 April, but it is now suspended until 5 May.
When the new baby was thought to arrive in April, royal watchers were keen to note that it could be born on the Queen's birthday, 21 April, or William and Kate's fourth wedding anniversary, 29 April.
Now, however, it is possible that the baby could arrive on the May Bank Holiday on 5 May, or the day of the General Election on 7 May.
Fewer that one in 20 babies are born on their due date and while it is unknown how many days Kate is overdue by, the option to induce labour is available on the NHS to women who are around ten or 12 days overdue.
The Duchess is thought to be several days overdue
The Duchess appears to be taking the delay in her stride and has continued to go about her normal day-to-day activities.
On Tuesday the relaxed royal was seen driving to Buckingham Palace to take Prince George for a swimming lesson at the residence's private pool, while Thursday, which marked four years since William and Kate tied the knot, saw the parents-to-be return to the iconic building where they shared their first public kiss as a married couple.
The duo were spotted driving to the palace and although the purpose of their visit is unknown, it's possible that they were joining their one-year-old son for a swim in the pool.
