THE OLDEST CHILD ACTS OUT WHILE DAD IS ON THE ROAD, DRIVING HER MOM TO TEARS, ON ABC'S "SUPERNANNY," JUNE 25

"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. Jo digs deep to find out what is motivating Hailey's horrible behavior, and finds that the youngster keenly misses her relationship with her frequently absent Dad and feels as if Mom doesn't trust her. Jo sets out to deepen the father-daughter bond and to develop trust between Mom and Hailey with some imaginative exercises. But she's also got to help build up Mom's backbone, since Michelle's passivity only feeds Hailey's unrest. Does it work? "Supernanny" airs WEDNESDAY, JUNE 25 (9:00-10:00 p.m., ET) on the ABC Television Network.
