My DC (age 9) has been bullied by another child for 6 months. It takes the form of saying my child is horrid, saying he is annoying but to multiple kids in the class, intentionally. At times it has involved mocking and pushing. The child has told lies saying my child has done something when has hasn't. School have not been great and the child has also extending the bullying to another child.
The mum of the child doing the bullying is highly critical of my DC and has complained numerous times over things like my DC tripping and knocking into the child's arm during tag. The child was not hurt, my DC was and my DC apologised at the time. But the child 'did not like it'
The latest complaint from the mum is that my DC talks about his outside school plans at school and this upsets this child. All children in the class do this. They regularly do show and tells and talk about play dates, holidays and parties. My DC has listened to others speak excitedly about their playdates. When my DC has felt left out or sad hearing about this I have said - this is a fact of life. They're not doing it to hurt you. You also do fun stuff/ with friends.
For context one of specific examples the mum has given to school is my DC talking to his friend about after school plans. My DC wasn't speaking to that child but that child overheard apparently. The activity they were planning to do was free.
The teacher spoke to my DC and told him he was not to talk to that child about anything he does outside or school. We queried this with the teacher today. And found out the mums complaint is that my DC has spoken at school about a holiday he went on at Easter (to visit family). Multiple children in the class went on holiday at Easter and have spoken about it at school. The "you can't talk about your outside school plans or activities" is only applying to my child. My child is neurodiverse and stressed about this. He is worried about being overheard by this child if he chooses to talk to a friend.
My take is that this is targeted action only to my DC by the school on behalf of the parent. That it extends the action of bullying form that child and family to my DC.
Do I have the right to see the full range of complaints about my DC from this parent? Would this come under a subject access request?
Would it be reasonable to say to school that this ban of talking about outside activities has to apply to all children in the class not just my DC or it will be discrimination?
Would this action by the teacher be worthy of a complaint to the school?
