How can we prevent our children from modern means of communication (social media)?

You heard the answer, that you prevent them while they are young and not let them go. And this requires Jihad (striving), it requires patience with them, it requires observing [them] and not being lenient. Otherwise, there is no doubt that society nowadays is, as you know, rife with temptations and evil. And if you let your children go to their non-religious neighbors and relatives, no doubt that they will be affected and it will be difficult to guide them. And preventing them requires patience, strength and being present, Because some fathers do not go to their house except late, or some nights they do not go to their house, and they do not ask about their children and do not ask about what is in their house. Even though he is the shepherd (i.e., guardian) in his house, "Each of you is a shepherd and each is responsible for his flock." [Hadith] The man of the house is a shepherd and is responsible for his flock.
