One child at 3 y/o DC’s nursery is constantly hurting the other children, including DC who has come home with several bite marks, marks from being hit and pushed etc.
We have raised concerns both in person and via email, and the staff have explained that they are aware of the child’s behaviour and are trying to manage it. But yet again today DC has a red mark on their cheek from being hit 
AIBU to expect the nursery to do something to manage this? I understand they often go through biting/hitting phases, but over the last 2 weeks there have been 4 occasions where DC has been hurt by this child now. I am considering pulling them out of the nursery.
