we had a good time...and compared to my current conventional preschool parent child class I postively pine for waldorf snacks (current is a co-op so the parents bring the trashy snacks. Really. Cookies, candy, cupcakes, donut holes. I was the health food freak for crackers, cheese, pumpkin bread, raisins, dried cranberries, etc. Cheese puffs are as good as it gets usually! for 2yo at lunchtime!!)
Anyhow, instructions through song, handwork, and a more beautiful and soothing environment than your typical parent-child class. I'm not sure I'm totally comfortable with everything waldorf, but the p-c class is perfect since I'm present for everything. I agree, a lot of it is about parent training. In my area there is a at least one and probably more waldorf playgroups too, for people looking to save money.
DD had a hard time at 16-18m being still for story/circle, so we would sometimes have to step out. We also had a very large age span (up to 3.5 yo maybe even 4) The oldest children sometimes had trouble knowing how to treat pre-verbal walkers...so we had some pushing and tears. Officially, I think waldorf wants children to work things out on their own...but I don't know what age that starts. Allowing toddler kids to push my toddler was not on my agenda, so I just kept an eye out and sometime tired to explain the older girls that while DD looked to be her age, she was really much younger and still mostly a baby. Our class had very tippy chiars too so that was always hard for dd who was new to chair-sitting.
