My lovely nephew has started taking other children's football cards, lifted things from his class and afterschool club. Despite being caught a few weeks ago and being reprimanded for it he has stolen football card again. This time my DSIL has marched him round to the child's house to return the cards. What is upsetting my DSIL the most is that he doesn't seem bothered by it all, like he's not quite getting that this is wrong. What methods have people used to punish bad/encourage good behaviour? Any ideas, thoughts?
