Like all royal fans, Prince Charles is eagerly awaiting the birth of Baby Sussex.
A source close to the royal family tells ET that Prince Harry's father, Prince Charles, is "over the moon" about becoming a grandfather again, after already being a granddad to his older son Prince William's kids with Kate Middleton -- 5-year-old Prince George, 3-year-old Princess Charlotte and 1-year-old Prince Louis.
The source notes that Charles is particularly a big fan of his daughter-in-law, Meghan Markle, whom he walked down the aisle at her and Harry's wedding at Windsor Castle last May. Since then, the two have been snapped smiling and joking together at royal events, obviously enjoying one another's company.
"Charles is extraordinarily fond of his new daughter-in-law Meghan," the source says, adding that he is looking forward to the big day Meghan gives birth and can't wait to meet Harry's firstborn.
Earlier this month, Meghan and Harry made the move into their new home at Frogmore Cottage at Windsor Castle, after previously living at Kensington Palace, where Will and Kate also reside. Our source says that one of the reasons for the move to Windsor was the opportunity to bring their baby up away from the “prying eyes of the paparazzi." But according to the source, Meghan and Harry have already been welcoming family as guests in their new home, which will continue when the baby comes. The source says a series of Meghan's closest friends have recently been to London to visit, and she has more visits scheduled after the baby.
It has been "a time filled with love and excitement," the source says of the couple eagerly awaiting their first child.
As for Meghan and Harry's plans for when the baby arrives, the source says the couple has opted to have a lower-profile birth in order to celebrate privately as a family first. Earlier this month, Kensington Palace revealed that Meghan and Harry are breaking with protocol regarding the arrival of their first child, and won't be immediately announcing the birth of the baby. Additionally, unlike Prince William and Kate Middleton, who posed for photos outside St. Mary's Hospital following the arrival of their three children, Meghan and Harry will have a photo op with their newborn on the grounds of Windsor Castle when they are ready.
The Sussexes "want to spend time with family and enjoy the first special days of their baby's life," the source says, adding that the public will have less access to Baby Sussex than George, Charlotte and Louis because the child is not directly in line to the throne.
