Ditto AC below.
Okay...no the Teacher CAN do something about it.
The school/Director... SHOULD have rules and policies about bullying.
My daughter was bullied in Preschool (when she was 3 years old) ... I told the Teacher. The Teacher said this child has caused trouble before to others. The Parents were called in and met with. They were told, that if it continues... their child will be asked to leave the school. Other parents, in addition to me, had complained about this child. The Teacher ALSO talked to this child.... the Teacher also talked to the ENTIRE class as well (without using the child as an example), and talked to about Bullying/proper behavior/what is unacceptable/how to tell a Teacher is someone if being picked on etc.
So yes, the Teacher CAN do something about it.
Yes, a child can be picked on/bullied...at this age. I saw it firsthand... with my daughter and the child that would pick on her. ON purpose. I saw it. My Daughter, was NOT in any way, an instigator. In fact, my daughter always steered clear of this child, because she knew she was a troublemaker. The Teacher even saw, this child pick on others.
I suggest, you DOCUMENT everything and write a letter, to the school.... expecting something be done about it.
You said your daughter was "hurt." This is UNacceptable....
It cannot continue...
You are the parent, you MUST advocate for your daughter... and EXPECT it be handled, properly by the Teacher and the school/Director.
all the best,
