Not sure about this but I wish they would have.
When DP went to pick up DS he was told that DS had been bitten by another child today. The little boy bit him so hard that he broke the skin through his jumper (Apparently he clung on until one of the teachers removed him). The teacher said DS was hysterical and he was still quite shaken and sobbing when he got home (He's not really a crier when it comes to getting hurt)
Now I know kids bite and it's usually no big deal (My niece was a biter and bit DS quite a few times but not to this degree) the nursery put an ice pack and a bandage on it and said they will take steps to make sure this never happens again which is great! But I do wish they had rang me to let me know this had happened and gave the option to take him home.
His arm is quite bruised and sore looking and DS is now reluctant to go back incase it happens again and the other boy "makes angry faces" at him. He said he cried for me and DP.
I probably am! But it wasn't nice :(.
