Sorry, just seen your message and it's now quite old. I've lived here in Birmensdorf for the last 6 years and have a 5 year old so if you've still got questions let me know and happy to help!
How are you? My name is Karina and I've been in birmensdorf for 4months with my partner. What nacionality are you? I'm Brazilian/British, I don't have kids but it would be nice to meet someone else...
Personally I think its too far from Zürich. Rural=boring. Not good for kids when they get older.And the locals are friendly -as long as you are not a refugee.
