It is well worth taking the time to be very specific about the duties you are expecting the au pair to complete. Do not underestimate the cultural differences that may be highlighted when you have someone new living in your house. If you like things done in a particular way, then these will need explaining and demonstrating to the au pair. Remember, the smallest of habits can lead to misunderstanding so, if you like the dishwasher loaded in a certain way because that works best, you will need to explain this. This area is particularly critical where an element of childcare is involved. We all bring our children up slightly differently, and you will want to ensure that the au pair reflects your desires and standards in all activities relating to the children.
