Ds is in a class of quite noisy kids (state primary, Y4) who seem to find it hard, as a group, to behave. This year's teacher has been saying 'damn' rather a lot - to the extent some of the kids are a bit bothered by it. I don't think it's acceptable, but what should I do? I like the teacher, she's young and newish, and apart from losing her temper things seem to be going fine.
