A live-in babysitter, also known as a NANNY, is someone who lives in the home of the family they are caring for and provides childcare services. They are responsible for taking care of the children, including feeding, bathing, playing, and providing emotional support. They may also be responsible for light housekeeping duties such as laundry and tidying up. Live-in babysitters are often employed on a full-time basis and may be required to work nights and weekends.
