Kate Middleton and Prince William's Baby no. 3 is going to arrive in April, and the hospital where she is about to give birth just dropped a major hint.

The Lindo Wing of the St. Mary's Hospital, where the Duchess of Cambridge will deliver her third bundle probably dropped a bomb in a subtle way. They had the railings outside the wing repainted. A photo circulating showed a "Wet Paint" sign at the railings. This just gives hint on when she will actually be giving birth, which is expected anytime soon.

Preparations

Clearly, hospital staff are gearing toward the upcoming arrival of the royal baby of Middleton and Prince William. The preparations are in order, as the newest addition to the family will make a debut in that place, so the hospital need only be picture-ready when the time comes.

To pump up the pressure on hospital personnel, Middleton and Prince William posed on the same area when the prim and proper gave birth to their first two children, Prince George and Princess Charlotte in 2013 and 2015, respectively. It was even where Princess Diana showed to the world Prince William and Prince Harry, so the tradition might probably still be followed in the upcoming birth. The Lindo Wing was last renovated in 2012, before Prince George's birth. It opened in 1937.

Middleton's Due Date

On Middleton's due date, several reports say it is on April 23. However, Kensington Palace only said she is giving birth in April and did not mention any specific date. The announcement came in October last year.

Of late, Middleton made a public appearance, but what is special with this one is that it was dubbed as the last for the preggo. Meaning to say, the next time the public will see the Duchess, it will be when she's with her newborn and probably be outside Lindo Wing.

Surely, fans will miss the fashionable royalty during the time she will be taking off from the spotlight. After all, she had been out and about in the past months, even with the baby bump visibly getting bigger.

Public Appearances

In late October, Middleton was seen playing tennis with none other than the lovely children of Tennis for Kids. Photos showed the expectant mom having the time of her life as she mingled with kids and coaches at the event. This meant that even while she's pregnant, she makes sure she attends to her duties, like that in January, when she went to the King's College to understand one of the pressing issues that moms experience: postpartum depression.
