Use of everything to the extreme is always bad. Just like every other thing internet also has advantages as well as disadvantages in our lives. Children life is a phase of learning. They learn everything they see or listen. So keeping them away from ourselves and close to internet or away for social media and close to ourselves is bad. If we don't keep a check on their internet usage and timings, then it may be harmful. Children nowadays knows more than adults. They know how to hide or delete their usage on internet. So, they mustn't be given their own personal internet devices. In my opinion internet is both useful and harmful. Children usually prefer videos on audios and articles and in internet they may get access to every kind of videos they want. We must have to keep an eye on them and make them able to differentiate between useful and harmful websites.
