So my son is 3 years old and has attended preschool for the last year now. About 3 months my son would come home calling us poo poo head, jerk, saying he hated us, and doing an annoying repeating thing after we would say something to him. I was concerned because he was not learning this sort of behavior at home so I figured maybe from kids at school. I expressed my concerns with the teacher who then informed me that she was having problems with one of the other boys who was teaching the others that stuff. I told her I didn't feel it was right that my son learn all of this and it was coming from one child. I get he is in school now and that sort of things will be said etc I just felt the way to handle the problem was for her to talk with his mother. Over the time things got a bit better but today I found some disturbing info. As the teacher and I were talking she mentioned she had to talk to that little boys mom again because lately he has been saying to the other kids "I want to kill you, I'm going to slit your throat, I'm going to shove your dead body in a trash can", he is 4 by the way...... First off my concern is where is he learning this from? Is this the kind of language used at home? I just fear not only for this child but my own now. I feel he is way to young to be exposed to this sort of talk, especially at preschool by a fellow classmate. The teacher said she would talk to the mother of the child again but I feel it will not stop. Now I'm debating whether or not I should find a new preschool? How would some of you handle this situation?
