We have very very limited screen time. It's all about moderation for me.
The children can have 30'mins each (but there are 4 of them, they pool it together) on a Saturday and Sunday.
They can use this for either tv or switch. (Limited games, just dance and Minecraft).
My kids are complete bookworms, love to do art and crafts and we swim 5 times a week. Plus walks etc.
The two older ones (12&13) have phones but it's limited useage. They use them the most for music. We have the right to check them, DH can see everything they looked at and blocked things like YouTube. They have to ask us for access to anything new. (I don't know how he does that, he is in IT).
Absolutely no social media at this point. We know that will come but for the moment we have explained why and they accept it. We don't use social media much as a family and they know why. We also don't have Netflix, sky, amazon tv etc.
I work in a school which is screen free, so the kids don't have great exposure. DC go there too.
It's really not hard, the biggest resistance is questions or confrontation from other parents who generally are shocked or think that it's weird. (It's not, we know lots of families like this). You will find yourself having to defend your decision every time it's brought up as many people will insist that screens do no harm to their children.
