Supernanny (2005)

The Froebrich parents get no respect. Erich and Beverly have 5 children ranging in age from 1 to 11 years old, and admit they need a Supernanny intervention. The Froebrich children smack, pinch, yell, fight and talk back, and homework is a battleground in which Mom brings her 11-year-old son to tears. Beverly's mom lives with the family since Beverly's dad died, and she considers her daughter a control freak; the stress for everyone has gotten worse since the death. Mom doesn't discipline the kids at all, but Dad will smack the children with a wooden spoon, pull their ears, and put hot sauce on their lips -- but neither parent's approach works.
