Agressive child in at School Montessori.
I am working in at a Montessori kindergarten. In my group there is one very aggressive child. He is aggressive not only for towards other children but for towards teachers as well. He is biting, scratching, kicking, etc. Many times I am often come coming back home with scratches and bruises on my legs and arms (sometimes even so hard that I have blood on my hands). The other teacher that who works with me reacts but nothing can change the boy's bad behaviour. He doesn’t respect anybody and even punishment (that shouldn't be used in Montessori) doesn’t change him.
How What do you think: what can I do in with this situation?
