Supernanny (2005)

The Coliers of Cleveland, Georgia, are a blended family on the brink. Dad Jason coddles his three young sons under the age of 5, but is hostile to his 13-year-old stepdaughter, Madison, whom he adopted last year. Jason showers his little boys with affection but his relationship with Madison is frosty and contentious -- she doesn't call him "Dad" and says he doesn't seem like one; he counters by saying she's a pathological liar and carries on "like a moron." Jason also spoon feeds his three-year-old and holds the older boys back from gaining valuable life skills by doing everything for them.
