Father of 10 years old. Technology is everywhere. Pixels, Gaming laptops, Youtube. I think my son have not seen an ad in a long time. TV is replaced with Youtube (mainly kind of stupid local streamers), all Chromes (phone, laptop, tv) are equipped with ad blockers. The time spend on these devices is not limited at all.

The trick is my son spends a lot of time on all kind of outside activities. Like playing with friends, language courses, math courses. When at home, I purposely try to find activities outside tech - like just chatting, lego before, currently doing random house projects. Also he is wikipedia expert - name a unknown topic and he is on wikipedia reading about it.

At the end he has like 2,3 hours free a day. He can do whatever he want - mainly playing games with his friends, when he is not installing all kinds of software he finds on internet.

So to sum it up - nothing is forbidden, time on devices looks healthy to me. I see some of his friends spending quite a lot time online though.

As for the ads, this streamer was advertising a stupid PC mouse. We bought it knowing it will be a disaster. His monthly budget was spend on it, it sucked and now he knows firsthand about the ads and as a bonus - he doubts the streamer and online content in general.
