If I tell them off for answering back/being naughty they look at each other and snigger. If I'm telling them off and say for eg 'Go to your room!' They'll say something along the lines of 'Oh I love going to my room.' Whatever I say or do seems to have no effect on them whatsoever. I'm really losing my temper and it's getting to the point where after school is just a misery for me and them. I'm snappy before I've even picked them up. They aren't always badly behaved but when they are I don't feel I'm handling it properly. After school seems to definately be the problem time and although I'm not passing the blame they do seem to be friendly with children who have similar behaviour. They go to a tiny village school so it's impossible to seperate them. I've smacked them, taken things away, sent them to their room etc I basically feel like a nagging old cow and I'm sick of hearing my own voice!
