Nannies and au pairs differ in regulations. Au pairs are young persons (18 - 30 years old) who go abroad to live with a native family to learn the culture in exchange for childcare. What’s more, an au pair works for a maximum number of hours per week. They also receive pocket money from the host family. In contrast, nannies get a salary like any other job. Their working hours are flexible to the family’s requests and are regulated by the country’s labour law.
