The evidence is slim that time spent by teens on a device is linked to lower wellbeing. My advice to parents is to ensure that your children have a mix of activities which may include time spent on devices. A combination of attending school, engaging in sporting, cultural or other interests along with family responsibilities such as joining in family meals and completing chores, face to face socialising with peers should mean that your child has only a limited amount of time to engage with digital devices and it seems that the science so far is confirming that this is a healthy approach.
