Whether or not you agree with the inclusion of "Gaming Disorder" as a diagnosis, this work highlights the fact that many children (and adults) struggle to control/manage their gaming activity. It is important to have clear parameters/limits regarding game use. However, when your child is not following those parameters and responds negatively to requests to stop playing, it is important to remember that your child is not giving you a hard time, he or she is having a hard time and therefore needs help rather than punishment.
