Nanny 911 is loosely based on the British television programme Little Angels, in which American families with unmanageable children are reformed by ex-pat British nannies, including one who served for the British Royal Family. A similar show, Supernanny, is its arch-rival.

Each nanny specializes in one area, ranging from proper etiquette to controlling temper tantrums. Each nanny attempts to help unruly families get into working order. The current nannies are Deborah Carroll, Stella Reid, and Yvonne Finnerty. Lillian Sperling decides which nanny goes to which family. It should be noted that Nanny Yvonne gets picked less often than the others.

The families that are eligible for the show usually have four or more children (though some episodes show homes with fewer children), and the children are usually younger than 9 years of age. The parents usually have an income that allows them to be upper middle-class.
