I work at a daycare and my son goes to kindergarten then comes to the daycare I work at after school. Yesterday he came into my room crying because another child and him were playing and the child somehow whipped my son in the back with a stick and now he has a huge bruise on his back. I asked the teacher in his class what happened and she said I don't know I didn't see what happened. I know you can't watch all of the kids 24/7 but it makes me angry that he has this huge bruise and she doesn't even know if it was an accident or not. My son told me what happened and who did it but the fact that the teacher didn't even see it makes me angry. They weren't outside they were in the class room so idk how she didn't see anything. Would this upset u?
