I realize that this is very early to be asking, but my niece has been wanting to come to Switzerland for 2 years now so we are looking for an au pair position for next summer (2010 May-Aug). She's the oldest of 6 children and has grown up helping with everything from diapers to dishes/laundry/cooking - she is very responsible.
I was trying to find her something around either the Zurich/Basel area as those are the two cities where I work/live and know them quite well (and enjoy them). She will be coming the summer before she starts at the university in the US and this would be a great way for her to experience a different culture and learn a language.
If anybody is at all interested, or knows somebody who would interested for next summer, please send me a PM and I can give you her email address directly.

Thanks!
