Royals There's a Major Royal Baby Clue Outside the Hospital Where Kate Middleton Will Give Birth! The groundskeepers at St. Mary's Hospital are in nesting mode! By Erin Hill Erin Hill Twitter Senior News Editor, PEOPLE People Editorial Guidelines Published on March 28, 2018 09:24 AM Share Tweet Pin Email The groundskeepers at St. Mary’s Hospital are in nesting mode! The railings outside the Lindo Wing at the hospital where Kate Middleton is due to give birth just got a fresh coat of paint — indicating that the royal baby’s arrival is imminent. A “wet paint” notice has been hung up on the railings outside the Lindo Wing, which is where Kate and Prince William will introduce their third child to eager well-wishers as they make their anticipated debut after the birth. According to reports, her expected due date is April 23 (which is St. George’s Day in the U.K.). Will and Kate posed for photos on the very same steps after the births of Prince George in 2013 and Princess Charlotte in 2015. It is also the same spot where proud mom Princess Diana debuted Prince William and Prince Harry following their births. Can’t get enough of PEOPLE’s Royals coverage?

Kate, who stepped out for her final engagement before giving birth last week, will likely be looked after in one of the more expensive suites – one of about 10 en-suite rooms set aside for births. The maternity unit in the Lindo Wing consists of 16 rooms: five for labor and 11 for postnatal care.

In the lead-up to Prince George’s birth, there were ladders in position across the road from the hospital doors for at least three weeks before Kate welcomed the baby prince on July 22, 2013.
