Dorothy and Kip Baulisch of Papillion, Nebraska, are deaf parents raising four hearing children. They rely too heavily on their eldest daughter, Melissa (18), who understands sign language, as a surrogate "hearing" parent, and it's put a huge strain on her relationship with them. She's giving up her youth to be a full-time interpreter in her own house. The three youngest daughters are nightmares -- Jessica (8) and Jennifer (7) challenge their parents to the point where they simply give up trying to control them; the youngest daughter, Kristin (5), ignores her parents completely because she can't understand what they're saying, and constantly throws temper tantrums. On a typical evening in the Baulisch household, it takes Kip and Dorothy at least three hours to get the younger girls to bed, as they run amuck through the house, refusing to settle in.

The oldest Park child, Kyle, 6, has attention deficit hyperactivity disorder (ADHD), but his parents took him off medication when they didn't feel it was working.

All the children act out, refuse to follow instructions and take dangerous risks, such as playing in the swimming pool when it's forbidden, but the parents, Heather and Michael, are clueless about establishing control or maintaining boundaries. The kids not only smack each other with abandon, but hit their parents and Alejandra at will.

He punches, shoves and hits, and has a bullying style, whether dealing with his big sister, Cally, 16, or younger sibs Corey, 10 or Carli, 9. All of the children swear like sailors and refuse to do chores, stubbornly saying that they're not paid enough per chore! Gina admits that she doesn't enjoy being around her kids, and husband David erupts in nervous laughter whenever the children defy him. His physical horseplay with Casey results in Dad getting injured, but he laughs it off, to Jo's amazement.

John and Sarah Manley have been separated for over six months. John has his own apartment but has tried not to disrupt his children's lives, so he has daily meals and spends every weekend in the family home, but overnights in his own apartment. The children, Max, 7, and Claire, 4, can't quite figure out what's going on, but they handle their worry and confusion by acting out with anger, backtalk, fighting and tantrums. A simple trip to the grocery store is so fraught with the kids' antics that Sarah cannot keep track of their whereabouts, and shoppers won't even go down the same aisle as the Manleys. Sarah finds it hard to hold her ground in the power struggle with her kids, partly because she's nearly as confused as they are about the state of her marriage.

Wisconsin parents Shawn and Shannon thought it would be fun to have a baby. They were only 18 at the time, and were stunned to discover that Shannon was pregnant with twin boys. The early years with Bryce and Brandon were relatively easy with the help of both sets of grandparents, but now those days are a distant memory, with the addition of a daughter to the mix. The twins, now four years old, have outgrown toddler stage and know how to flip their parents the bird, hit, kick and curse like sailors when they are told "no."

In the midst of this, an unexpected family secret is revealed that affects everyone in the house.

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.
