The Krolikowski Family Supernanny : Season 4 Episode 21

Shannon and John both have high profile jobs at a large church, but their home is a far cry from a peaceful sanctuary. All four of their children fight with each other so viciously and so frequently that mom usually intervenes only if someone has drawn blood. That happens regularly because the kids bite, pinch, kick and pull hair for all they're worth. Mom's yelling isn't working, and Dad says he spanks to discipline, since he doesn't believe that timeouts or talking work. But in spite of the hardline tactics, neither parent has much authority. How will Jo deal with these challenges, especially with a dad resistant to her methods?
