lead by example
Parents should try not to play mobile phones in front of their children, set an example and guide them correctly.
In a dredge way of education
If the child has become a "mobile phone control", parents should focus on sparse, not containment.
Reach an agreement in advance
Every time a child plays with a mobile phone, make an agreement first. For example, if you behave well this week, you can play your mobile phone once on weekends.
Control how long you use your mobile phone.
Every time you play mobile phone, you should control the time, not too long.
