Our son is attending school. Your job would be to pick him up from school at lunchtime by bike (!). Since there is no lunch there, you would have to make him a little something. Maybe he needs a break first or you can start with his homework.
Our daughter has to be picked up from kindergarten at 2/3 p.m. When you get home, you can play with the children, read aloud, do crafts, bake, go to the playground or meet other children from the neighborhood. Another au pair lives a few houses away. Maybe you can do something together with the children.

Sometimes we need help around the house, e.g. vacuuming, washing or moving laundry, tidying up toys, setting the table... You are responsible for your own room. You have to clean it yourself. But if you want, your clothes can be washed with the family laundry.

As our children are still young, they only speak German. You need at least A1-Niveau.
Furthermore, there's a lot of water here (the river Elbe, small moats), we have a little pool and we go swimming regularly, so you need to be able to swim.
