Mine probably had slightly less on some weeknights as they did a sport 2 nights a week but definitely more on the weekend. I never had children who had a lie in so they were up at 7am, quiet as mice and would make a lovely cup of tea for you in bed when you woke up.
They also did all chores without being asked, homework to a very high standard, had family lunches and dinners with us and everyone chatted. They also helped prepare dinner, set the table, cleared away afterwards. We played co-op board games together, cards, played musical instruments etc. We also watched films together every weekend at home and some tv shows. It is about balance.
In my opinion it does depend what they are doing whilst on tech. Ds2 is like a sponge so would spend a lot of time learning about world history, engineering and the likes. The games he played were things like Kerbal Space Program where you build a rocket to fly to space but you had to calculate payload, boosters and fuel and it is based in realistic aerodynamic and orbital physics. Ds1 learned how to play both piano and guitar from Youtube.
Both children played co-op game with each other or their mates. It is how they all talk and connect over headsets when they live a 45 minute walk away from each other. They are on opposite catchment borders for their school. They have never played Call of Duty or GTA but have played first person tactical shooter games like Valorant and Counter-Strike.
It also depends on their attitude too, what frame of mind are they in when they come off the tech? Are they okay coming off? Are they jubilant from playing? Happy even? If they are aggressive and churlish then we would ban that game for a bit but we would talk to them about how they were feeling. I filmed Ds1 getting a certain level in a game and honestly he is pure joy. There was not a lot of rage quitting or anger. When they were younger they would get upset at games not going their way but again, we talked to them about it. It also helps build resilience.
Ds1 played that game for his university. Ds2 is at uni now and also plays e-Sports for his university. They both attended top tier universities.
@CeciliaMars if all their mates are playing a co-op game where you work as a strategic team to achieve a goal and your son or daughter is the only one not allowed then they are going to feel left out. This isn't limited to the game playing but also conversations in school about the game they played, how they will work better next time. It is just a different life than we had. Homework is also online a lot too so they are researching websites for information.
