Bully darvo-ing dd

[RockStarship]

Dd (11) has been bullied by one girl in her class for the past 6 weeks. The bullying involves exclusion from her friendship group, name calling, belittling her, humiliating her, coming up with a derogatory nickname for dd and encouraging other children to call dd this name, giving her constant dirty looks, whispering about her to another girl and when dd looks over at her (having heard her name) the girls start laughing...the list goes on. This girl started off targeting dd on her own but she has now got two other girls involved. Dd feels scared to go to school most days, cries a lot at home and is emotionally all over the place- she's not herself at all.

A couple of DD's friends have told me what these girls are doing to dd and I've found some heartbreaking messages on DD's phone to another friend outlining what these girls are doing and saying she doesn't want to tell a teacher what is happening unless it gets worse.

I have spoken to the teacher about it and she was sympathetic. The teacher spoke to the three girls- two of them have backed off a lot although they're still making snide remarks within earshot of dd and referring to dd by the derogatory name to other children. However, one of these girls has decided on a counter attack approach and now keeps bursting into tears and accusing dd of giving her nasty looks, talking about her, saying nasty things about her. No other child bar the other two bullies has been able to back this up, and tbh this doesn't sound like something dd would do. Dd just wants to be left alone and deliberately winding up other children is not something she has ever done in the past and I can't imagine for a second would be something she is doing in a situation where she's frightened of these girls.

Dd and I were told by the school that every time these girls do something to dd that we need to let them know so they can investigate what has happened, yet dd has reported a few things this week but the teacher just said "oh ok, thanks for letting me know" and hadn't done anything else. The teacher has also ignored an email from me about dd being called the derogatory name.

Dd feels alone, and I feel so upset and angry that dd is suffering so much at the moment and the school are dismissing things that are happening to her. On top of that this girl is now trying to get dd into trouble. This girl did the same thing with an another girl in their class and the other girl ended up being moved to another class.

Can anyone advise me on how to handle this situation because I feel helpless.
