Hi all
When I went to pick up dd (16m) from nursery yesterday, they took me aside before I saw her to say there'd been "a biting incident", then showed me the 2 big bite marks on her face. It was apparently a 2.5yo who had "misunderstood" what dd was doing (trying to grab a toy, probably). My first reaction was pretty calm, "don't worry, these things happen" - possibly partly relief as my first thought had been that dd was the biter 
But later the crazy mummy emotions kicked in, when I got a good look at her poor face. The bites didn't draw blood thank god, but she has 2 pretty nasty circular bruises, and one bit is grazed. The thing I got upset about was that she was bitten twice, i.e. the attendants didn't notice/ get there in time to stop the second. It is not a huge nursery, there were 5 or 6 children there yesterday and 3 adults. Dh is pretty angry about it, and wants me to speak to the nursery (though not sure what what I'd say or ask of them).
Thing is I have no idea how common or serious this type of incident is - I don't have much experience of nurseries or 2 year olds for that matter.
So this is a double AIBU I guess - AIBU (and probably suffering from PFB syndrome) to be annoyed that they didn't intervene quicker? Or AIBU to not be more outraged than I am? I really can't tell if I'm over- or underreacting! What would people do/have people done in a similar situation?
