Hullo there Mrs B

, only place I could find was this
http://kinderbetreuung.liliput.ch/it....aspx?Id=17360 It's in Ittigen, so not too far away, but not sure if this is what you are after at all.
As well, from what I could make out with my shaky French, she should be 3 yrs of age, but I won't tell if you don't
Otherwise, suggest putting a notice up say, in the Migros or Coop to ask around about a French speaking buddy for her. My French is abysmal so I can't offer to write out a notice for you, but you could probably write it up in English and be surprised at what response you get.
Good luck and please to give those two sweet-peas a little squeeze from me won't you.
take care now,
Ros
