The 37-year-old Duchess of Sussex has been taking classes in the trendy approach — which relies on natural child birth methods and self-hypnosis techniques — at the yoga center she secretly visits in London.
And her husband, Prince Harry, has even been talked into attending a session with her to familiarize himself with the methods.
"Meghan has always boasted of her super-healthy lifestyle," a palace insider told RadarOnline.com. "She is fixated on making the birth as natural as possible so she can boast to her L.A. pals she went drug free."
But Markle has been warned her hippie-style birthing plan may be overruled by royal protocol, which states the baby's safety is paramount.
"It's just not the 'done thing' in the royal family," pointed out the insider. "If something went wrong then they would want Meghan surrounded by the top doctors and the whole hypnobirthing idea doesn't really sit with that."
Despite the rules, the expecting mom is "determined to do things her way," said the source, adding, "She is adamant that this is the birth plan she will follow, but she could have a fight on her hands."
As RadarOnline.com reported, Markle is due to give birth in April to her and Harry's first child together.
And while Markle's mom, Doria Ragland, will be in England for the big event, her daughter also plans to fight protocol by having her move permanently into Kensington Palace once the couple's bundle of joy arrives.
"They definitely don't like non -members of the royal family being too much on the scene," said the palace source. "So Meghan will come up against some resistance to that idea."
"She really wants her mum around as any woman having their first baby would, but the royals are no normal family and they tend to keep 'outsiders' away from actually living in any of the palaces or having too big a role in the day-to-day life of a prince and princess," explained the source, who noted Meghan doesn't care about keeping the peace.

"Meghan says she wants Harry to step in and clear it so her mum can be at the palace and even have her own quarters there," revealed the insider.
"It's putting Harry in an awkward position because he wants to do what's right by Meghan but he also knows it's not the way things are done in the royal household."
