Sorry, I don't know of any groups in your area. In fact, I'm going to tag myself onto your thread since the header is general and ask if anyone knows of any playgroups in the canton Neuchatel. English speaking is great but not necessary. I'm closest to La Chuax-de-Fonds, but I'm so desperate [okay, that's hyperbole, but you all know what I mean] that I'm willing to drive. I have a 3 yr old and we don't know another soul with young children.
There is a English speaking Pre-School in Bulach old Town which is only five minutes from Kloten by car and 10 mintues by bus,their website is www.first-steps.ch,my son goes to the Art Class and Reading and Writing Class and loves it!!!
