My daughter is in year 3. A new girl recently moved to the school and it seems (from what my dd is saying) that this child is playing manipulative games with the others (they are only a class of 7) - one day including some of the children but not the others in her games and generally stirring up trouble and being divisive. She also encouraged others to bullly ad taunt my dd about her watch and ear muffs (which the teacher has said she is allowed to wear). The teacher apparently dealt with this but problems are still going on. This girl is as nice as pie to my dd one week, trying to encourage her to come to her house etc and then turning on her the next (and doing the same with others as far as I know).
My dd has always been a popular girl who generally gets on with everyone and is rarely involved in conflict (as stated in her school report). Now for the forst time, she's coming home very unhappy though. I have told her that she needs to communicate with her teacher but she just dissolves to tears and says she feels sick.
The problem is of course that there are always going to be people you don't like in life and who knows why this girl is behaving like this (I tend to think you can't blame a child for their behaviour). But I don't know how to help dd deal with the situation more effectively.
