JO FROST FACES HER BIGGEST FAMILY YET -- 10 KIDS! -- AND AN UNEXPECTED FAMILY SECRET IS REVEALED, ON ABC'S "SUPERNANNY"

"Costello Family" -- Amy always dreamed of having 12 kids, but she had no idea how hectic it would be. With husband Dale on the road most of the week as a truck driver, and 10 kids ranging in age from 6 months to 15 years old to take care of at home, Mom is so overwhelmed that she's unloaded half of her parenting responsibilities onto her teenaged kids. The younger children couldn't care less who is disciplining them; whether it's eldest brother Logan, 15, or their own father, the six kids under 12 have no respect for authority, barely do chores and revel in the chaos. Meanwhile, Logan and his teenaged sister, Carley, 14, have little time with their own parents or friends because they're wrapped up corralling their younger siblings. In the midst of this, an unexpected family secret is revealed that affects everyone in the house. Jo Frost has faced challenging situations with families with lots of kids, but can she help the biggest family we've ever seen find some balance and harmony? Find out on "Supernanny," FRIDAY, FEBRUARY 6 (9:00-10:00 p.m. ET) on the ABC Television Network.
