The editor of the NST has with the help of many Zurich based people published a book called

In and around Zurich with Kids

http://www.thestork.ch/html/guide.html

In this book you will find almost everything that you possibly would like to know.

You can order it from the NSt website but if you want to flick through before shopping, it's on sale at Orell Füssli in Zürich
