I hardly ever swear, well never unless you count the very occasional things like crap and get stuffed as swearing which I don't
Have two DDs who are 6 and last few months I have noticed a few swear words creeping in, not used maliciously, but things like this is f rubbish, or where is my bloody bag.
At school they got marked down for swearing a couple of times but they have not really made an issue of it
It was a post on MN a few days ago that got me wondering, how do you all handle swearing by your DC, do you allow it, turn a blind eye, punish or does it depend
