He got hit in the eye by his classmate (using a water bottle) on Day 1 of school & I was told by the principal that its a "small matter" & its a norm that children fight.
No medication was administered by the form teacher. He was crying alone at the back of the queue waiting to be dismissed. When I questioned the teacher what happened to my son, she just told me off abruptly to bring my crying son home. "Are you his mum? can you bring him home now? he can't stopped crying." These were the exact words that she used when I asked her what happened to my son. (The incident happened while they were queuing up for dismissal)
i think the principal gave you a straight forward and frank answer.
i wouldn't want teachers to give or apply medication to my children, except for first aid for emergencies such as heart attack or choking. teachers are not doctors. what would be appropriate is to call up the parents if the child is sick or injured, or for serious injuries, to send to clinic or hospital.
my very young child got into a "fight" with someone bigger, and i think double the age, and lost and ended up crying. i said i will teach you to fight, then you can fight back better next time round.
