After helping stressed-out parents regain control of their kids, Jo Frost is calling it quits. She wants to have a family of her own, and her job hasn’t left her any time for dating, much less parenthood. Here’s hoping her dream comes true and that she’s the kind of mom she’s helped many others to become. In the series finale, she works with a family that has no mom — she died of cancer, and Dad is at his wits’ end with his three boys.
