The job of a housekeeper nanny is to perform the dual role of child care and housekeeping. Depending on the family, you might be more focused on one role than the other, but there is always a combination of the two. Your responsibilities revolve around assisting the household in any way needed. Your duties generally include cleaning, cooking, and looking after the children when the parents are not around. Especially if you are an independent contractor, there are no universal qualifications needed to become a housekeeper nanny. However, nanny or housekeeping agencies may require experience in childcare and cleaning, as well as a high school diploma or GED certificate. Moderate cooking skills are usually a must, but other qualifications vary by employer.
