Hi Doris,
We're moving to Geneva mid july with our 7month old daughter - so I'm watching this thread with interest! I think if you search the history of this forum someone has posted a thread about some playgroups in Geneva.
On a recent visit I picked up a copy of the know-it-all passport from a bookshop. It has loads of information about playgroups/activites with children in Geneva. They have a website which has some links on it:

I found this on it which looks like fun!

Feel free to PM me if you would like to chat - it might be nice to meet up for a coffe once we've moved out - you should know all the good playgroups by then
