Prince Harry and Meghan Markle's Baby Is Reportedly Due Sunday

Prince Harry and Meghan Markle may just be welcoming their first child today, according to a new report.

The Sun broke the news that Markle's due date allegedly falls on Sunday, amid rampant speculation about when the royal baby will arrive.

As for how the Duke and Duchess of Sussex are handling the big day, they are apparently "on standby but relaxed." Markle is apparently opting for a natural birth and has been practicing her breathing techniques alongside her husband.

"It won't be long now. Meghan's really excited. Of course she's nervous like any first-time mum but she and Harry can't wait," the outlet's source said. "She's been preparing for the birth – she wants it to be as natural as possible – and so has been practicing hypnobirthing and breathing techniques with Harry."

Despite the due date falling on Sunday, Harry is apparently keeping up appearances by carrying out his civic duties as the Duke of Sussex. He made a public appearance in London on Sunday during the 2019 Virgin Money London Marathon. He greeted competitors and volunteers, as well as championed the event's charitable impact and sense of community.

Today, The Duke of Sussex, Patron of The London Marathon Charitable Trust, attended the 2019 @LondonMarathon where he cheered on runners, thanked volunteers for their selfless support, and congratulated the winners. The Duke has been Patron of the Trust since 2012 because he believes that mental fitness is absolutely crucial to our wellbeing. These runners not only set a goal for themselves personally and emotionally, but the majority of runners choose to raise money for charity. It’s the perfect fusion of doing something good for yourself while doing good for others. The joyful atmosphere created by locals, tourists, families and friends speaks to the spirit of what community is all about - supporting one another, even complete strangers. The @LondonMarathon is the biggest one-day fundraising event on the planet. This year’s Marathon will see the total raised for charity surpass a record-breaking £1 billion. So for every runner, volunteer, sponsor and member of the public that has played a part in making today a success - thanks a billion! Photo cred: PA

Despite Harry being out on the town, Markle is not alone. The former Suits actress' mother, Doria Ragland, is with her daughter at Frogmore Cottage as she prepares for the little one's arrival.

"It's been a huge support having her mum by her side and now she's just getting as much rest as she can."

Meanwhile, The Sun also reports that signs forbidding drone use have also been posted around Windsor's Home Park, which encompasses Frogmore Cottage. This possibly signals the royal family's attempt to stop photos of the baby leaking ahead of an official announcement.

The royal family has not responded to the publication's due date report as of press time.
