Narei, cerca un babysitting a Zürich

Hello ! We are a couple of scientists from France participating to a conference in Zurich, and since it's now holiday time in France, we need to bring with us our kids. We would need help to take care of them, for example when both of us would like to attend the same part of the conference, or for social evening events (like conference diner).
We would need in total something around 10 hours of babysitting during the week of July 8th.
Our kids only speak french ! It is thus mandatory to be able to understand and speak french, even if this is not fluently.
Don't hesitate to ask more questions if needed !
