Traumatised my 5year old child

My son is being bul**** at this school by both teacher and some learners, he reported that the teacher hits them with a wooden stick on the head and shouts at them. He is literally scared and you can see that his confidences and self esteem has gone down, I cannot wait for the year to end so I can take him out of this school. He’s only 5years and in Grade R🥺😭 when I complained about it, the teacher told him not to share what happens at school at home. I’m even considering home schooling.
