I am not sure if this is the right place to post, hopefully it is. I am at a complete loss as to how to sort out a problem at school.
Dd is 6.5 kind gentle hardworking girl, never ever been in trouble for anything. She has been 'friends' with a little girl since reception but it has always been very tempestuous to say the least. Not on my dd's part. In the beginning she would come home with fairly deep scratches on her hands and arms and seem very distressed and not want to go to school. She tried to explain what was happening but I decided to see for myself. I volunteered as I planned to anyway at our school. The little girl hurt my daughter regularly. I didn't get involved, I called the teaching assistant to sort out any disputes and kept my distance. It was eye opening to say the least. On just one occasion she came up behind my dd who was playing with the dollhouse and smacked her round the head with a large hard plastic doll, she regularly used to lay on her and crush her.
The teacher was fantastic and dealt swiftly with the problem, I spoke to the parent and we actually ended up quite friendly, she is a lovely woman and mum. Unfortunately the incidents continued and the little girl became very domineering and controlling over my dd the more friendly they became. It is awful to tell your child not to play with someone and I did try very hard not to do this. The little girl also tore up a book dd had brought in for a project, the teacher apologised and offered to replace it. It all came to a head when my dd ended biting the girl in retaliation, she had had enough and quite literally bit back. The school were again great and said it was understandable as she had put up with so much, dd apologised to the girl and the mum and I had a chat and agreed her dd was too boisterous but my dd should not have retaliated (she had as I said put up with so much I wouldn't have lasted that long) and we would work together to make sure things were ok. I secretly hoped dd would eventually drift away and form other friendships but the girl wouldn't really let her.
Moving into year 1, the first term dd came home with a deep bite which was bleeding. I spoke to the teacher she thought they were great buddies and was surprised but took it very seriously. Dd was extremely distressed. Mother apologised and brought a sorry gift in, little girl also very sorry. There were several incidents throughout the year but none as serious, mainly little girl banging into dd very hard, grabbing and shouting at her but all in the name of play apparently. Dd still wanted to be friends and I kept on trying to have a good relationship with her mum so it would be easier to sort out any disputes.
Dd is a creature of habit and personally I feel it is a habitual friendship as she can't avoid the girl at school even if she wanted too. They moved into year 2 this September, all was quiet until mid December. Dd came home so upset as the girl had allegedly pushed her over and crushed her in the style of behaviour from reception, wouldn't let dd get up. She also kept kicking her leg one day and wouldn't stop, I have taught dd to clearly say please stop or I don't like that and eventually to tell someone. Little girl kept saying these things were accidental.
We went to their nativity and dh and I were watching as little girl repeatedly head butted our dd as they were sat quietly, a teacher was also sat very close by but obviously couldn't see. We wanted to get her attention but too far away. Dd ended up giving her a push back after moving away several times which stopped her. Had a teacher seen that they probably would have told dd off not realising what had happened.At home dd was upset and hurt that this had happened as she just loves school and hates the behaviour of this girl. I was planning to go in to speak to someone but dd came home and said she is being nicer mummy I will be ok. I explained I would still come into school but discreetly and try to make things better and ensure it didn't happen again.
Against my better judgement I left it for a few days,but asked dd to let me know if anything else happened. More physical stuff did so I contacted the mother to say please could you have a chat and try to explain dd is unhappy and in her words frightened of the little girl because the boisterous behaviour has started up again. She said she would talk to her and I heard nothing more.
Coming back to school in jan I left it a week to see if the mum would speak to me and planned to yet again go back into school to speak to the teacher but yet again there was another incident,the girl apparently screamed in my dd's face frightening her so much she fell and bruised her head. The teacher said they were playing tag in the cloakroom, dd is absolutely insistent this was not the case at all.Today it was a nasty scratch on the top of her hand. The teacher at the time dealt with this as dd said it was on purpose. The girl admitted it and apologised. I finally had a reply from her mum, very matter of fact saying she had spoken to school they didn't see a problem and if there were any issues would contact us. No thought to dd being hurt, she said she was aware of the incident but had no concerns. I realised today she too has had enough and is no longer prepared to sort it out with me. She asked school how could she know what was going on and didn't think there were any problems. In denial, sadly so, and who wouldn't be but it is not going to help matters at all 
I went in for a meeting to discuss all of this with the teacher and was so shocked to find her defending and trivialising the incidents. She did in the end after checking with previous teachers and the history of incidents say they are taking it all seriously and making sure my dd is happy and safe but the mother feels HER daughter is being picked on because I have asked that this stops. Is it me or am I going mad in thinking this behaviour is no longer boisterous or never really was? The teacher even said yes she is very boisterous but doesnt mean any of it and is mortified afterwards. The mum had shown her my text but declined to mention we were actually friendly and had always managed to sort things out, it looks as though I have randomly text her asking that her daughter stop this behaviour. I explained everything to the teacher and she was surprised we had a good relationship.
I have been so so so patient as has dd and dh but we have all had enough. Going back in tomorrow to discuss today's injury but with dh this time who is livid but will be calm (I hope) the thing which comes to my mind is my dd has never( apart from the retaliation incident 2.5years ago) hurt another child or her siblings, she is never hurt by any other child at school accidental or otherwise. There have been far to many other incidents to mention. I just got the feeling that the behaviour is being dismissed, the teacher spoke about a nurturing group at school to teach the girl about boundaries and such like as i said if she honestly doesnt mean itand doesnt understand then can you help her to not push herself on dd and understand she is hurting her,then she went on to speak about improving dd's confidence to speak up. She bloody well has numerous times!!! I want to know if there are to be any consequences in future for physically hurting dd, I want it to stop now but realistically I don't see how. This is massively long but I feel we have done everything right and are being royally fobbed off. Thank you if you have lasted this long
