Over the last few days British bookmakers have slashed the odds of the Duchess giving birth on little Lottie's big day, but all details of the where the royal baby will be welcomed have been kept firmly under wraps.
Last month, Kensington Palace said the royal couple "look forward to sharing the exciting news with everyone once they have had an opportunity to celebrate privately as a new family", Express.co.uk reports.
However, reports have surfaced indicating 37-year-old Meghan has opted for a home birth at Frogmore Cottage and will be taken to NHS Frimley Park Hospital - 30 minutes drive away - should any complications arise.
The Surrey-based medical facility was reportedly placed on standby yesterday.
"The plan has never changed. Meghan has been very clear what she wants," a source told The Sun.
If Meghan and Harry's baby is born at Frimley Park, they will be the third royal delivered there.
Prince Edward, the Earl of Wessex and his wife Sophie, Countess of Wessex, welcomed their first baby girl Lady Louise Windsor at Frimley in 2003.
The Wessexes' second child, James, Viscount Severn, was born there in 2007.
Other sources say the Duke of Sussex and Meghan's baby will be delivered at American-owned hospital The Portland, where Sarah Ferguson welcomed her two royal babies Princess Beatrice and Princess Eugenie of York.
One thing is certain, thought - the former Suits star will not follow in the footsteps of her late mother-in-law Princess Diana who started the trend of giving birth at the Lindo Wing of St Mary's Hospital in London, welcoming her two sons with Prince Charles there.
Kate Middleton echoed the Princess of Wales' trailblazing choice and gave birth to her and Prince William's three children, Prince George, Princess Charlotte and Prince Louis at the ultra-exclusive, $11,000 AUD per night Lindo.
Meghan and Harry's new royal baby could break records just a few months after their birth if reports from the Express are accurate.
ABC News' royal correspondent Amy Robach claims Their Royal Highnesses are considering taking Baby Sussex on a long tour of Africa.
While details of the trip have yet to be announced, if the plan goes ahead the newborn would break their cousin Prince George's record by becoming the youngest member of the royal family to travel overseas.
Ms Robach said: "Buckingham Palace say they will not comment on an official visit so far in advance but is this trip does happen, and they do take Baby Sussex, he or she will be one of the youngest royals to take to the road."
"In 2014, Prince William and Kate Middleton took Prince George on their tour of Australia and New Zealand when he was eight-months-old and there was some serious royal baby mania down under."
Baby Sussex will be seventh in line to the British throne and the fourth grandchild of Prince Charles and the late Princess Diana.
According to Express.co.uk, punters are expecting a baby girl with Elizabeth in top spot for the royal baby name.
Diana, Grace and Victoria are other strong contenders, while Alice, Albert and Philip all have odds of 12/1.
