Premanand Maharaj Ji
How do I handle my children's use of mobile phones and technology?
Be a friend, watch, and keep them unafraid
Talk to your children privately and as a friend, check their phones, and go to their school to look into their character. Govern them with love, and tell them not to be afraid to tell you if they make a mistake.
Parents should take their children aside in private, in a friendly way, and slowly explain their faults to them, saying that this will harm them.
