09:53 here. No, I haven't brought up my concerns with the director yet, because I've been waiting to see what happens, since the center has only been open a week. I figured, "Maybe it's growing pains."
My child was at a center (DC's spot has been taken, as well) where when DC walked in in the morning, the teachers smiled and started singing. There was always lively music playing, and all 3 teachers were young and vibrant. Not to be ageist, but most of the teachers at the center are past their 40s. One morning when I walked in, the teacher and an aide seemed so irritated with the kids as they took their snack. The aide actually reprimanded one child loudly and firmly put him back in his seat when he stood up. I walked in, and there was no smile from the teacher for me or for my child. The aide didn't bother to say anything to me.
Granted, I am there only for drop-off and pick-up, so perhaps things are different during the day. But I somehow doubt it. It would be helpful to have other parents weigh in.
