I want to distract the child from viewing the smartphone. Son is 9 years old. He is not interested in reading books like I was when I was a child. He plays phone or computer in the evenings. I'm thinking of finding an alternative job for him. But I can't think of any. What can you advise?

Are you unable to install a parental control type program? Who allowed the child to use the gadget uncontrollably? Do you know what is harmful? You can see at his age for about an hour a day in total. I suggest that you purchase such a learning device as a home planetarium. This is a really entertaining device that allows the child to learn a lot about the planets, space, constellations. One disc is sold with the device. but it's better to immediately order flux star projector discs https://astronomix.info/planetarium-discs.html
