Some families get rid of TVs and smartphones for the proper growth of children, but are those things desirable?

I think it's desirable. When exposed to the media from a young age, you won't be able to control it because you're still growing your self-control ability. In that case, if you are exposed, you can't control the use of your smartphone by yourself. You should be exposed to the media after you have some self-control. In order to have self-discipline, you must be 5 or 6 years old.

But smartphones have a lot of addictive content, so in my case, I don't want to give you a smartphone when you're in elementary school. Because if you spend a lot of time with your family instead of watching TV, it will have a more static effect than the positive effects you can get on TV.
