Hi.
As for the personality / nurturing issue: Your child's teacher does it differently than you would.
And I would say, think of that as a strength. If she is fair, calm, and kind, what does your child lose? Nothing! In fact, she gains a model of how a different personality functions in a somewhat different (but still decent, just) society. That is a plus! Your care providers need not share your personality.
I will just say that I think one of the greatest things we give our children when we send them to school is the chance to participate in another culture, another society.
However, the money and age-inappropriate expectations are a problem. On the other hand, she might have appropriate expectations but just tell two-year-olds to color in the lines. (I am not sure if coloring sheets are very Montessori--I thought not.)
I say, look at some other places. The money issue would bother me. Payment shoudl be transparent and simple. Otherwise, she's just asking for drama and who needs that?
