Thanks to all of ya'll for the great responses! I am the OP, and, after much reflection, have arrived at the conclusion that this incident was probably a good thing, much as I hate the fact that my dd was hurt & confused by the other childrens' behavior.
Ultimately, this little incident provided me w/some valuable insight into how this director handles what I believe was bullying behavior. I know, earthmama4, that kids in the preschool age range are exploring their world & know only what they've been taught by their parent(s), teachers, etc. ... so I don't blame these children. Of course not. I view the adults' inaction (most notably the director's & her assistant) as totally inappropriate. And while I fell in love w/the classroom & crafts & all organic snacks, I cannot in good conscience send my dd to a school where she's already been badgered & none of the adults acknowledged, re-directed, practiced GD, whatever. If I was right in the room, what would happen if I dropped her off for several hours? Oh, and this & the makeup incident were not the only things. Dd told me later, clearly frightned & upset, that one of the little boys told her that if she even thought about entering his improvised fort that he would "knock her head off."
Now, I didn't witness this, I was probably peeking into the other room or something, but I was shocked. She's never said those words before. Now, I saw the little boy she described. He looked older, about 6, and was obviously isolating himself the whole time we visited, sitting in a corner, outright refusing to participate in the circle, etc. None of the teachers ever tried to engage him. Maybe he had emotional or learning difficulties, Idk. So I felt badly for him as well. And, yes, I know that kids are kids and that this sort of thing can & probably will happen ANYWHERE-- but I expect that the adults in charge would attempt to stop it. That said, I am so glad dd stood up for herself & was able to stop the taunting before I had to get involved & get all "mama bear". She is very much a leader.
JennifaBest, I certainly did talk w/dd. She was clearly hurt. It's been 2+ wks, and she still brings it up. A couple of days ago, very sadly, she said, "I'm different from those kids. I speak Spanish. And they don't like the toys I like." Very sad, IMO.
Though I have been very upset, I really did my best to stay calm & objective, both during our Waldorf school visit & since.
MamaInCA & zinemama, I did calmly communicate my concerns to the director & brought up these incidents. I even thanked her for allowing us the opportunity to tour her facility. Her response was basically, "Okay, since you've communicated your disappointments, you're obviously not interested in our school." That's it! Pretty sad, considering that I read about her school while I was pg & kept it in mind as a very viable alternative ever since. Oh well. Guess we won't be a Waldorf family unless we ever move. The only other "Waldorf inspired" school in our area is 50+ miles from us, and the only other one in TX to my knowledge is in Austin. Guess I'll be exploring Montessori now.
