Hi
We have been to this class with my little girl and she loved it, the lady could speak English and to be honest not much language needed during the 30 min class apart from me asking questions....ofcourse all the songs are in German.
this is the website and they run in different places www.babys-im-wasser.ch
I have a swimming school and we have babyswim classes on Tuesdays and Wednesday mornings. Here is a link to our Facebook page where you can see our photo gallery (we have parental permission).
Our courses are held in Kilchberg¨Get back to me if you have any further question.
