According to the Sunday Telegraph, the 39-year-old is due in June and will begin her maternity leave in about four weeks.
"It will be the summer and they want to make sure they both take their leave so they have some real quality time together once the baby arrives," a different insider previously shared, adding that they will "both take some proper time off."
The pair first revealed they were expanding their brood on February 14. "We can confirm that Archie is going to be a big brother," a spokesman for the duo said. "The Duke and Duchess of Sussex are overjoyed to be expecting their second child."
Meghan and Harry's friend Misan Harriman also shared a photo of the couple outside, with the Suits star touching her growing bump.
"Meg, I was there at your wedding to witness this love story begin, and my friend, I am honoured to capture it grow," Harriman captioned the sweet snap. "Congratulations to The Duke and Duchess of Sussex on this joyous news!"
During the tell-all interview, which aired on March 7, the couple revealed they were having a baby girl.
"To have any child, any one or any two, would have been amazing," Harry gushed. "But to have a boy and then a girl, I mean what more can you ask for? Now we've got our family, we got the four of us and our two dogs."
Meghan is planning on having a home birth in their Montecito, Calif., home, an insider revealed. "It’s a beautiful setting to give birth to her baby girl," they shared.
In the meantime, Harry recently flew back to the U.K. to attend Prince Philip's funeral, while Meghan's doctors advised her to not to travel. According to royal reporter Omid Scobie, she "made 'every effort' to travel but didn’t receive medical clearance from her physician."
