Your DD will probably be fine, mama . . . and so will you. No need to shoot yourself
My DD started preschool last year at the same age. We researched extensively to ensure the perfect fit for her and our family. I *still* didn't like it once she was there. I don't like her teachers. I don't really like the school. I missed her terribly. But she LOVED it. She looked forward to going every day. She missed it on days off.
"My beautiful angel has never ever been picked on, put down, shoved around, hit, kicked, bullied, judged, betrayed"
Neither had my DD. Last year . . . pretty much all that happened (albeit not often). But she STILL loved it. She would matter-of-factly tell me what sounded like the most horrible things, and the next day she would be best friends with whatever perpetrator it was.
"I want her to always feel as beautiful and wonderful as she does now"
My DD still does, and more so. She is even more confident, happy, and amazing than she was before starting school. My stomach is in knots as the days fall toward September (especially as I just finished reading Hold on to Your Kids), but she can't wait to go back. I lobbied hard to her to let me switch her to what I believe will be a much better school, and she refuses to switch. She LOVES her teacher (of whom I am not a fan) and can't wait to see her again.
The ps school system may not strip her of that . . . it doesn't ruin everybody. I'll bet the vast majority of MDC mamas went to ps, and look at how wonderful they are
And here's your (and my) lifeline: if it's horrible and she hates it, you can always pull her out. But I'll bet she loves it. Just send her with her own purple crayon so she doesn't have to wrestle with the monsters
