6 smartphone habit is negatively impacting kids

Nobody would want to put their phones aside when they were kids. Instead, they would rather lose hours on end to online gaming, which has the potential to become addictive. This shortens their study period and clashes with their sleep, which makes it more difficult for them to concentrate in class.
This is the point where parents should establish game time limits, particularly on school nights. To keep kids entertained without using devices, introduce them to offline hobbies, sports, and reading.
