Nanny 911 is loosely based on the British television programmeLittle Angels, in which Americanfamilies with unmanageable children are reformed by Britishnannies, including one who served for the royal family. The introduction features montages of several clips of unruly children, whereupon stock footage shows a "call" being made to Nanny 911 where "Head Nanny Lilian" answers "Nanny 911". After the intro the selected family is featured on a separate clip. Head Nanny Lilian and the other nannies - "Nanny Deb", "Nanny Stella", and "Nanny Yvonne" discuss the clip, whereupon Lilian announces which nanny will visit the family. The nannies are featured visiting the family in traditional nanny dress. The nanny's first day is spent solely in observing the family dynamics in order to determine a suitable plan of action for changing the children's behavior; at the end of the daythe nanny discusses what needs to be done. The remainder of the week shows the plan being implemented, along with the parents' reactions. At the end of the week, the nanny generally compliments the family for the changed behavior. The last segment shows the family receiving a substantial gift from the nanny. The families that are eligible for the show usually have four or more 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. After Season Two, the gift portion was removed. In Season Four, Nanny Yvonne did not appear due to budgetary reasons and the format changed. Rather than showing a clip to the nannies then deciding which one would go, Lillian just called one of them and sent them to the family. In some episodes this season, the nanny observes for two days rather than one.
