A nanny is a person whom provides child care. Typically, this care is given within the children's family setting.Throughout history, nannies were usually servants in large households and reported directly to the lady of the house. Today, modern nannies, like other domestic workers, may live in or out of the house, depending on their circumstances and those of their employers. There are many employment agencies that specialize in childcare. Nannies in many areas are a sought after member of the workforce. Many nannies become a part of their family's household. Although previously looked at as a lesser-than job, today's demand has made it a popular and valued addition to the lives of the family's household.
