I have twins who will be 3 in a month. They are very quick! They go to nursery and we have (unfortunately) had to sign the accident book a few times. Mainly they direct their frustration at each other.
The injuries in the photo are pretty bad, but one of my boys hurt his eye by falling off a chair and onto the corner of a table. It was horrible, OH felt awful as he was sitting next to him and didn't catch him. We took him to hospital to have it checked out, and luckily he was fine. Looked awful for a long time.
The accident report looks normal to me, aside from the biting which is excessive. I feel really sorry for the little girl who has allegedly done these things - unless this is all witnessed by parents or the nursery staff are telling the parents who it was (they are not allowed to, and from the article they wouldn't anyway) then how do they even know it is this girl all the time? Two and 3 year olds are not always so reliable.
And maybe the reason she is in nursery is because the mother can then charge for looking after a child her age and thus she earns more money?
Just trying to find some rational explanations as this story is borderline hysterical.
