@amit @KimberlyHirsh Ohhhh yes that makes sense. Hmmm that's tough. I think peer pressure is inevitable, especially this more subtle kind. The only thing I can think of is to provide the best support in which you help her develop her independence as well as an understanding that it's ok to feel the need to fit into the group.
It's a very difficult balance, that's for sure, and I assume a lot depends on her own behaviour and the person she is and is becoming. I can only think that the best thing for her family to do is to be available for support, and provide opportunities in which she can both develop her independence and feel confident that she can confide in whomever she would like to.
