check out this book by john gottman- i have posted on it before-it outlines really helpful ways to deal with your childs emotions and help them to identify how they are feeling and what they can do to feel better-its called 'the heart of parenting-raising an emotionally intelligent child'it also has a lot of ideas as to how parents can learn to 'coach' their children through different emotions so that the child learns about their emotions and how to identify what they are feeling and why. i would really encourage you to check it out. good luck!
