According to the insider, Meghan struggled without a support network in the UK.
“She said that being pregnant in the UK without any of her family and friends felt incredibly lonely and uncomfortable for her.
“So she’s keen to change that the second time around and would like to buck tradition to ensure she’s happy – although that may ruffle feathers along the way,” they said.
The news comes as the Duke and Duchess are set to take a six-week break from their royal duties.
During this time off the couple plan to spend time with Meghan’s mother, Doria Ragland.
The royal insider explained that Meghan wanted some time to recuperate from her official duties and quality time to bond with Archie.
The source said: ”Meghan wants to spend the first three months post-birth at home in LA with Doria and bond with the baby away from prying eyes.
“It’s the place she calls home, after all, which she says is vital for her mental health.”
The insider added: “Harry was initially concerned at the implications of having their second child in the US, as well as the problems it could cause with his family.
“But it’s believed he’ll support Meghan and do whatever it takes to make her happy and alleviate any anxieties or stresses.”
