How do I handle my children's use of mobile phones and technology?
Replace scrolling with katha and family kirtan
Use the same screen for good: play a katha or discourse for the children, and sit together as a family for kirtan in the evening. Children are reformed by what you do, not by what you tell them.
There's no problem with the mobile as such. Open YouTube and put on a katha. Children will hear four good things and learn four good things.
