If you can give a small certificate and a small award to encourage your child to behave well, I personally feel that it is not good to find a teacher. The first point is a matter of principle. If you don't deserve it, it's meaningless to go. If you don't deserve it, you will give the child false praise and give the teacher a feeling that you like the child very much. Teachers will inevitably wear colored glasses.
Of course, it still needs to be judged according to the actual situation. I don't think you deserve it, so don't ask for it.
