Hosting an au pair it is a great experience for all your family. You will have the opportunity to meet somebody from another country with another culture in your own house. It is a nice experience to share your own culture and language with an au pair. Like a host family you have to treat the au pair as an equal member of the family. The usual practice is that the au pairs eat with the family most of the time and join in some of the usual family activities such as outing and trips.
Both the family and au pair are expected to respect cultural differences and display tolerance towards one another.
