Erin and Jacob Harmony are at their wits' end raising three boys -- Jake (11), Ian (5) and Grant (3). Big brother Jake is not the big problem, but his two little brothers are. Ian is the master of back-talk. He torments Grant into frenzies, and the two have violent battles. Grant's temper gets so out of control that he bites furniture until he bleeds from the mouth. He has major separation anxiety, and has been known to follow Erin's car all the way to the highway when she tries to leave the house. On top of it all, Grant wakes up at 3:00 a.m. every morning and insists on sleeping with Mom. Dad gets so fed up with the crowded conditions that he moves himself onto the living room sofa! With discipline attempts going nowhere and no one getting any sleep, this family needs Supernanny now. Can Jo restore harmony to this household?
