Trying to have fair and realistic screen time rules for 8yo?

[boomsonicca]

I never went overly strict on screentime rules and it never seemed to be a massive issue, and I didn’t want to make it a forbidden fruit.
Lately however my 8yo son has become more and more obsessed so I think I need to step in now with some boundaries before he gets older and it gets more difficult.
I want to be fair and realistic, cos I do want him to be able to enjoy what he likes, but I don’t want it to take over.
I know when I was younger and I played games, an hour can fly by and sometimes it is fun just to have a good proper play. So I want to find a good balance.

My initial thoughts are
Mon-Thursday
No gaming at all,
YouTube up to an hour per day
More flexible on Netflix series/movies

Fri-sun gaming/youtube allowed (do I give a time restriction?)

Any tips on what works for you??? Flexible, fair but firm approach is what I am looking for.

My eight year old has no screens at all Mon to Thursday (no TV or anything). He is allowed it from 3 on weekends. I try and limit it further during this time by offering alternatives and he loves board games and things. If we are out and about, he obviously doesn't have it. I find it easier to have yes or no times rather than limits as I don't have to think about what they have already had and juggle adding up multiple screens. Time limits are great and my elder kids have time limits on their phones, but I find that when they run the time out on one device, they will go over to a switch or an iPad or the television. Whereas if they are only allowed it in certain time periods, I don't have to think too hard about whether it is a yes or a no!
