Which statement best describes the role of nannies?

The role of nannies is best described by the statement that they care solely for children from one family. Nannies typically work in a domestic setting, providing personalized care that caters to the specific needs of a single family. This involves not only looking after the children but also engaging them in developmental activities, cooking meals, and sometimes assisting with household tasks related to the children.

While there are other childcare options such as childminders or nursery staff who care for children from multiple families or in a shared setting, nannies focus on one family's needs, creating a more tailored and consistent environment for the child. Their role is distinct in that it often includes building a close relationship with the children and the family, which is key to their effectiveness and the trust placed in them by the parents.
