I am a mum of twins, aged six years . One daughter is very popular. At home she speaks her mind but with friends she goes with the crowd and tends to be a follower. The other daughter gets on well with others but prefers to spend time on her own at times. She speaks out regularly when she sees injustices and doesn't like the cattiness that goes on in the friendship group. As a result she sometimes gets left out. Her sister, rather than support her, leaves her and joins 'the gang'. This breaks my heart and I'm not sure what to do. I applaud my one daughter for being strong and having strong morals and standing up for what she sees as wrong but at the same time , to get on in life, sometimes you need to just bite your tongue. I want her to be strong and independent and have integrity but don't want her to be ostracised for it. How can I help her find a happy medium?
