What is happening in your teen’s brain? Want to peek inside? Healthy 15 – 16 year olds may engage in some thrill seeking. Help them experience positive thrills so they don’t have to find them through alcohol, drugs, or sex. Teens may be stressed about grades, relationships, or their appearance, but they’re also developing their sense of self and defining who they are as individuals. They go from know-it-all to unsure, from concrete thinking to abstract. Keep the lines of communication open and set safe boundaries so teens can process their problems and come up with solutions.
