Was Steiner advocating this or just stating where he saw things going?

Not advocating at all, if you study the modern Anthroposophic doctors (based on Steiner's philosophies) they have a fascinating view of the benefits of childhood disease as a part of a child's spiritual evolution. So every fever and every illness helps to fortify one's development. If you look at books by Dr. Michaela Glockler they will cautiously and neutrally suggest very few vaccines in certain circumstances. Glad I discovered Steiner before I had my kids :)

Back in my day, our parents used to take us to someone's house who had a child sick with measles or mumps, so we would get it and be done with it... It worked.. This was the old kind of doctoring. We also played in the dirt, outside every day. We drank water straight from the outside spout. Used what they call old wives tales remedies that always worked. Need to get back to this. 💞💓👍

LOL we pretty much do live like this, except we drink our water from the ground (a local spring) ... we are lucky and blessed.
