Hi, I need some rational advice here. When I picked dd up from nursery yesterday I was informed that she had "unfortunately" been bitten by another child whilst arguing over whose turn it was to wash hands at the sink (!) I was ok until I actually looked at the bite. There is a perfect imprint of every tooth which is raised and swollen and this morning going purple with bruising. Obviously nursery can't tell me which child did this but this morning dd didn't want dh to leave and was really quite distressed. Nursery won't say whether the child has done it before and are really being quite evasive about it. I seem to be getting more upset about it by the minute rather than less.
What do you think I should do (if anything)?
