Jamie Lynn Spears a role model for motherhood to Britney Spears?

"As happy as she was for all the joy Jamie Lynn is experiencing it was heartwrenching for her to think about her own situation with Sean Preston and Jayden James," a source close to the singer tells OK!. "She knows she has to do whatever the court, her attorneys and her doctors tell her to get the boys back."

Britney is finally ready to participate and play the game. On June 24, the singer,26, went before commissioner Scott Gordon asking for a change in her custody. In a huge win, Gordon granted Brit one overnight a week with her boys.

"Legally, Britney is a child," the insider tells OK!. "How can Kevin possibly give up any custody of his children to someone who is a child herself?"
