We don't mean to alarm you, but "Royal baby watch" has officially begun.
The suspended parking notices will run from today until April 30, so it's just a waiting game from here. Prince George, 4, and Princess Charlotte, 2, are the current children of the Duke and Duchess.
The barrier installation comes after royal photographer Arthur Edwards spotted that the railings outside the Lindo Wing were being painted last month.
The Duke and Duchess of Cambridge, who do not know whether they are having a boy or a girl, will introduce their baby to the world when they leave the Lindo Wing through its now famous front door, before returning home to Kensington Palace.
This is because the two-year-old will become the first female royal to retain her claim to the throne irrespective of whether her new sibling is a boy or a girl, reports the Independent. Kate's precise due date has not been announced, although Kensington Palace confirmed that William and Kate's third child is expected in April. Her birth dominated the news agenda in the United Kingdom and hit the headlines around the world.
Kensington Palace made the announcement in September previous year, saying that the Queen and members of both families were "delighted".
October 10 - Kate, showing a slight baby bump, makes her first public appearance since her pregnancy was announced as she attends a Buckingham Palace reception honouring mental health campaigners.
Nonetheless, Kate and William have certainly perfected this whole routine. Their father Prince William was also born at the same facility.
In the Lindo Wing, Kate will again be given a bespoke experience akin to a five-star hotel with en suite rooms available "providing a modern, homely environment in which to start your new or expanded family life", the unit's website states.
