Re: My child does not like school
My younger brother had a similar problem, he got a new teacher at school and almost immediately he changed.
He didn't want to go to school, and he would come home with a change of clothes because he had soiled his during school.
My parents had a feeling it had something to do with the new teacher. I can't remember if this was around the same time or not, but one day he came home with a plaster on his finger and he had injured it somehow, but there was no explaination as to how this had happened.
In the end my parents went in to the school and had a talk to the headmaster.
I'm not entirely sure what happened, but I know the teacher was changed again (not sure if the previous one was fired), and soon he was back to normal.
My advice would be to talk to someone senior at the school and explain your concerns. If as you say other parents have concerns as well, they will have to look into it to find out what the problem is.
