I'd pick her up, put her in the car, and drive her to school no matter what, even if she's in the middle of a tantrum. I'd tell her, "we'll talk about this later." And I'd make sure we did talk about it, although in a calm, matter of fact kind of way (not yelling and name calling). She needs to know that you'll be in control no matter what, so that she feels safe. I'd definitely be sure to talk to her and others about what's going on, too. For years, I was miserable going to school, and no one ever bothered asking me why. Not a good feeling... but she still needs to know that using words, not acting out, are going to be helpful to her. Good luck! I have a two year old and some days, like you said, I'm ready to throw a tantrum myself, so I understand. Take care--Lauren.
