As one would expect, welcoming a royal baby is a royal operation. From the security detail in the maternity suite, to the precise labor schedule, Kate Middleton and Prince William‘s birth plan for baby number three proves that no detail goes unplanned when it comes to tiny Palace newcomers.

With her due date rapidly approaching (reportedly April 23), it’s just been confirmed that the Duchess of Cambridge will deliver in a luxe suite in the Lindo Wing of St. Mary’s Hospital in Paddington, London, just as she did with the births of Prince George and Princess Charlotte.

The royal suite at St. Mary’s is far from your average maternity room, a source spilled to Us Weekly. Suites reportedly run upwards of $9,650 per day, and Kate and William’s exact room has been on lock-down since mid-March.

“Security does regular sweeps of the room, then it’s resealed each time with tamper-proof tape,” the insider revealed. “It’s a high-security operation. Even the crawl space above the room is checked regularly.”

And despite the fact that Middleton has given birth under similar security pressures in 2013 and 2015, the precise planning is only amping up in preparation for baby number three.

“Everything is planned down to the tiniest detail,” the royal insider explained to Us Weekly.

Per Us, there’s even an assigned “baby team” on high-alert at Kensington Palace, awaiting the official labor announcement.

The team (which includes Middleton’s mother, Carole), “is dedicated to making sure everything is ready, from media plans to security to hospital arrangements,” the source explained. “There’s a backup plan for everything.”

When the 36-year-old expecting mother does eventually go into labor, she and Prince William will drive directly from the Palace to the maternity ward at St. Mary’s (which is less than two miles in distance), and notify the hospital just moments before they arrive.

“The hospital will get only five minutes’ notice ahead of Kate’s arrival,” shared the royal source. The timeline is scheduled to be tight in order “to prevent anyone being tipped off that she’ll be leaving home,” the insider explained. “And because everything is organized so precisely, the hospital can handle such short notice.”

For the anxious brother and sister-to-be, Carole Middleton will reportedly jump into grandma duty, caring for Prince George and Princess Charlotte at Kensington Palace while their parents are at the hospital.

Finally, when the fifth in line to the throne makes his or her arrival into the world, per traditionan official letter noting the child’s birth date and time, sex, and weight, will be posted on an easel outside Buckingham Palace. For those of us in the states, a social media announcement will follow.

After the birth of the baby, the turnaround and recovery process is also expected to be speedy. “Depending on how Kate feels, it’s hoped she can return home the same day or the following morning,” said the insider.

With birth plans in insanely-detailed order, we couldn’t be more excited for the royal family’s new arrival to finally, well, arrive!
