Jamie Lynn Spears and Casey Aldridge preparing for the arrival of their baby girl

They've moved into their new home in Liberty, Miss., the town where Casey grew up. It's only 30 minutes from Kentwood, where mom Lynne Spears lives at Serenity, the estate Britney owns and where Jamie Lynn was raised.

The couple's new $300,000 house has four bedrooms, a large yard and a swimming pool, something Jamie Lynn told OK! was an absolute essential.

"I love to swim," she said.
"Britney will almost certainly have to juggle some of her visitations with her kids while she's off seeing her sister and new niece," an insider tells OK!. "She's not going to want to miss too many of those."

"As soon as she knows Jamie Lynn is in labor, Britney and her dad will be on a plane," a source close to the family tells OK!.
