As an au pair, you will be living with your host family like a regular family member assuming daily tasks throughout your stay with them. As a „son or daughter for a defined period of time“, you are primarily in charge of childcare, a task which requires a great sense of responsibility on your part. Furthermore, you will help with light housework related to childcare, such as:
preparing the children's meals
washing and ironing their laundry and putting it back into the wardrobes
helping the children tidy up their rooms
taking the chidren to school or their spare time activities and back home
helping them with their homework and supporting their school development
However, you should not only be aware of your duties, but also of your rights: an au pair is neither a nanny nor a home help or carer for the elderly. He or she is no employee, but must be considered a fully adequate family member throughout his or her entire stay as an au pair.
