Question
I have 3 step daughters ages 10, 13, and 15. I never have had a sister but my nieces are close in age and the best of friends. My daughters won't share and are so mean to each other. Attitudes, snide comments, facial expressions so hateful!!! They are always on each other about the way they chew, dress, grades, weight - just any opportunity to get in a jab. The negativity is contagious. If one of them wants to borrow something they won't let them and even if they offer for the other to borrow something in trade they won't do it. I have never seen anything like it. What should we do? I have tried to show a positive example and show kindness but so far nothing is working. Please help....
