My DS is 5 and in Year 1.
He's just come home from school with a big bite mark on his arm - skin not broken but teeth marks visible and a large bruise. It apparently happened in class this morning and caused him to cry for quite a while. The other boy was told off by the teacher.
Now I know boys do this sort of thing and am happy that the teacher has dealt with it properly.
What worries me is that the school didn't mention it at all. Is this the sort of thing you'd expect them to tell you?
We had a slight problem last week too when DS came out of school in tears. He wouldn't tell me why and so I asked his teacher the next day if anything had happened and she just said, "yes I noticed he was crying as he came out but there didn't seem to be a reason".
