Today was my last day working in a nursery as I am leaving to go to a new nursery. I spoke with a little one today who had some marks on her. Some bruises/mark on neck. Small scratch under the eye, larger one under neath that. And a large scratch on the arm that was deep and bleeding. I asked him what he had done and he said ‘mum’ then pointed at the marks and said ‘mum, mum, mum’ and then ‘mum’ again and hit his hand against his head. I said ‘who did that?’ He said mum again. Reported it to the room leader who wasn’t concerned and said he thinks because his speech is behind why he was saying mum. But to me , I took it more serious. As I’ve left the nursery now and they didn’t take it seriously. I don’t know how to approach
