Exactly. All of this screen time is bad for kids and the phone is the devil reincarnate is ludicrous. The type of content they are consuming is what parents should monitor. Allow kids to use the device appropriately. If they do something with the device that you deem as inappropriate, then talk to them and correct the behavior. It is through mistakes that kids (and adults) really learn. Sheltering and avoidance will do nothing to prepare them for the real world once they reach early adulthood.
