As a weekend nanny, your duties entail providing childcare and completing household tasks for parents. In part-time weekend nanny jobs, you work a Saturday-Sunday shift. You may commute each day to the house or stay there for the weekend. Your responsibilities vary depending on the unique needs of the children and parents for whom you work. You may care for one or more children only at the home, arrange and participate in activities, prepare meals, supervise homework, transport them to events, or run errands for the family. Other duties can include cleaning the home and helping bathe and groom children.
