My DD is in year 6, but recently has taken to being unkind by name calling and putting her siblings down. She also makes sarcastic barbed comments. DH and I do not do this, so I am not sure where she gets this from. My younger DD and DS are confused as they are not used to this either and get very upset by her comments.
We have explained to DD many times, that name calling hurts people's feelings and is not acceptable. We have also tried docking pocket money - but neither approaches are working. Any ow other ideas how best to deal with this?
