Understanding your child and his or her behavior is the most important skill you should have as a parent. A child starts showing his or her personality gradually from birth to age six. They are young explorers and each one has a unique personality and different traits. Thus, each child expresses differently. The real change or growth begins in the adolescent years … 6 to 12 years. During these years, you can see the dominant personality of your child, such as Peace Loving, Problem Solver, Organizer, Leader or a Rebellion. You as a parent need to learn the skills necessary to work with your children through their teen years and beyond.
