I have attempted to give my DC an 'old fashioned' childhood in some ways (lots of family time, crafts, outdoor activities, books, board games etc etc), but firmly believe that denying them access to technology is pointless - and actually detrimental in the current day and age.
Why deny your DC screen time, or the opportunity to develop good technological skills, when it is so obvious that they will need to be tech savvy to access decent education and career opportunities? Why force a child to try and do their homework on a parent's mobile phone - hugely frustrating and limiting - when it must be blindingly obvious that this approach disadvantages them and will continue to do so?
I was watching my 14yo work on a homework project this afternoon. He's at a highly academic indie school, he is a very high achieving child, loves learning. All of his homework is set via the school IPad. All of it. Am I supposed to contact the school and say no, it all has to be paper based? What good is that going to do him in the longer term?
Eldest DC is at uni - again, high achieving - aiming for a 1st. Every assignment is set online; every assignment is submitted online, and feedback is provided, yep, you've guessed it, online. If he'd been denied sensible access to tech throughout - with severely 'old fashioned childhood' values (TV only, and maybe half an hour on an IPad once a year?) he would probably be failing his degree.
As with all things, we can aim for a balance. You can put in sensible rules without being autocratic; you can allow your DC to develop skills without being permissive. It is entirely possible for a child to love gaming and to be a keen reader, for example (DS2, who games like a maniac and reads like a geek).They can be a Minecraft expert and also love climbing trees (looking at you, DS1). Or spend many hours on Fortnite and many more drawing beautiful sketches (that'll be DS3).
Honestly, you can allow DC to have phones/tablets/gaming devices and set reasonable boundaries around them and it is possible to have old fashioned elements of childhood whilst acknowledging that the world has to move on, too. But I genuinely think that children whose parents are draconian about severely limiting tech access/denying access altogether are at best making them vulnerable and at worst failing them in the longer term.
