I understand that mother instinct and wanting to protect one's child fiercly. The poor girl! What an uncalled for thing to happen.

I would bring behaviour like that to the attention of the school principle. Something in general should be said to the entire school. But then again, that might embarrass your daughter further ... so I don't know.

Continue to love your daughter as you do. Reinforce the fact that it is NOT her fault and that those children are fools. All you can really do is be there for her, every time she might want to cry about it or talk about it. Hold her often - as there is nothing more soothing than a Mom's comforting hug.

You are obviously a wonderfully kind and supportive Mom.

I really feel for you and your poor daughter.
