Everything to Know About Meghan Markle and Prince Harry's New Home

A source tells ET the Duke and Duchess of Sussex have finally moved into Frogmore Cottage ahead of Baby Sussex's birth.

Meghan Markle and Prince Harry have so much to celebrate!

In preparation for the arrival of their first child together, a royal source confirms to ET that the Duke and Duchess of Sussex have finally moved out of their two-bedroom home at Kensington Palace and into the 10-bedroom Frogmore Cottage.

According to the source, the home was gifted to them by Harry's grandmother, Queen Elizabeth II, and is "a stone's throw" from the queen's Windsor Castle, where the parents-to-be are expected to spend Easter Sunday.

Meghan is "feeling great" ahead of her late April to early May due date, says the source, adding that the former Suits star and her husband couldn't be more excited about starting their life together with their new baby.

"[They] are keen that their child will be able to enjoy their privacy away from the goldfish bowl," the source says of the couple, who are "over the moon" about Baby Sussex. "Harry's attention is completely absorbed with the birth of his first child. He can't wait to become a father. He's been doing everything he can to put Meghan at ease."

Frogmore Cottage has been completely remodeled over the past few months, a process Meghan has been involved in every step of the way. The renovation includes everything from double panel windows and noise proofing, our source says, to two conservatory extensions, a new kitchen and several fireplaces. The royals' new residence also features extensive gardens, which the source notes will allow Meghan and Harry's kids to play outdoors and enjoy their childhood away from the paparazzi.

Another advantage? The home provides a space for Meghan's mother, Doria Ragland, who is expected to be in London for the birth of Baby Sussex. Our source says she is not expected to permanently relocate to the area, but the new home will allow her to comfortably stay for extended visits as she gets to know her first grandchild.

While Meghan will surely be happy to have her mother by her side as she enters this new chapter in her life, the duchess' close pals have no doubts she'll be a natural.

"She'll be a fantastic mother," one of Meghan's friends tells ET. "She is so wonderful with children and they are both so excited."
