I have twin boys who are 5.5 and I have recently started getting a constant refrain of "I'm telling!" followed by one of them running through to me and moaning about how their brother messed up their puzzle or kicked them or snatched a book or whatever. Now one of them has also started telling me that at school he often "tells the teacher" when other children are being naughty (very minor league stuff like forgetting to wash their hands etc...).
I think I have probably made the mistake of reacting to it and telling off the other child but I now want to put a stop to it. So any advice on how to stop the unimportant stuff without coming down so hard they never tell me anything??? For example, I am worried about them not telling me if they are being bullied or something. And I also don't want them to become hideously unpopular at school because they are constantly grassing up the other children....
