A nanny is an individual who looks after children. This care is usually provided in the family environment of the children. Nannies have traditionally worked as servants in large homes, answering directly to the lady of the house. Like other domestic workers, modern nannies may choose to live in or out of the home, contingent on their own and their employer’s needs. Childcare-focused employment agencies are plentiful. In many places, nannies are in high demand as employees. A lot of nannies settle in with their families. Despite being viewed as a lesser-than-job in the past, the demand for it today has made it a valued and popular addition to the household of the family.
