If a child had entered to a wrong path, the answerable is adults. It should not be proved. Adults of that child have to bear all of the responsibilities. Adults have to show their child the correct path. Adults have to show their children the correct path. Therefore they attend them to pre-schools.
Some parents give their children what they do not have to give. Every time this is on the love but the harm is hidden. Present parents have no leisure to stay with their children. Therefore they try to give their children such things. They do such things because of the love and for console their children.
To drive children to the correct path, parents have to show the goal to the children clearly. Then parents have to decide what their children need to achieve that goal and give those to their children. First you have to guide your children to go to the goal. Most of the parents give their children the technology, but they do not know the usefulness or harmfulness of that technology. If parents had any understand about the danger or harmfulness of that they may be able to watch what their children do. New technology is compulsory to children. But when you give these technology you have to understand the danger side correctly and watch if children do such wrong things.
Therefore concern very much about what your children needs and when they need those.
