thank you my friend! as i mentioned it was my first visit to one of those forest-kindergartens, and i was astounded of how balanced those kids were. in the morning it was a little bit rainy, they just stood outside and danced in the rain :D so fund to watch. but those kind of kindergartens are very seldom here in asutria as well .. government doesn´t sponsor it a lot, even though they are much cheaper because you do not have to pay a lot of rent for them ..
they also started as "private kindergartens" here in austria, so maybe it is a business idea indeed. if you need some more information i´d be happy to help you.
