Well, children should probably not have unrestricted internet access. If necessary, the parents should establish a while list and only add sites needed for things like homework, education or supervised entertainment.
Internet is not a safe place, its like taking a country boy/girl to a large city and leaving him/her there abandoned.
The problem with that is that kids learn to break those restrictions. Many of them
start to watch porn before they are teens.Even girls watch porn at a young age. When porn was only accessible when you had to go personally to a store to buy a magazine or a DVD, very few women watched porn. And the few that did were adults and they used to do it as a couple.
Today girls have access to porn in two clicks but I don't think that is making them adults before time, it's just that things are different.
I think that if they tried to learn on how to break those restrictions, then the parents is kinda late when they start to put restrictions on net surfing. They should make it start at earliest as possible. Children's curiosity will be always at the peak at their young age. The more you restrict, the more they rebel. Ergo, proper explanation about the reasons, and understanding on the concept on how they think will be the key.
Apart from that, parents should also give the effort to try to learn how to put extra securities, blocking and supervision in the home wifi, It is not that hard to learn ways on how to restrict them strictly without breaching their privacy.
when we were at childhood, really me and my friends did not any type of thing that do i adult age(like sex and lust things etc).Because we all time palyed at field, ground and outdoor game. But now a day child do not go outside for play, they just use mobile phone and watch tv. So can we blame on tv or social media???
in your example, the difference between that is outdoor activities will be a physical activities, while using mobile phones and watching tv is just an activity. there's not much difference between those two, both can communicate with their friends, play games, and learn new things while you're at it. The thing that we must perceive is that, we must supervise, like the old days. They must have restrictions about the time they are able to play, conditions to get a hold of the gadgets, and strict guidelines on the things they are allowed to do.
