Supernanny - Season 4 Episode 20 Moy Family

Since Dad, Harding, has taken a job that requires him to travel away from home Monday through Thursday every week, his oldest daughter, Hailey, 11, acts out, setting the tone for behavior for her siblings, who then misbehave too. Hailey openly discusses how much she hates her sister, eight-year-old Camryn. She pulls her sister's hair and belittles her, trashes her four-year-old brother Matthew's projects and defies discipline around the clock, driving her helpless mom, Michelle, to tears. Hailey even hits her mother when she doesn't like what she hears. When Dad's at home, he is no more effective in enforcing discipline.
