Serious suggestions

• steal huge amounts of media - books, movies, shows, radio serials, whatever you can get, and give it to them. Just whatever crap you can steal that isn't algo-driven dopamine thief predatory skinner box stuff. I bet someone has a torrent of the entire run of sesame street, shining time station, peewee's play house, beast wars, cspan. Steal it. Give it to them. Let them go nuts with it, engage it on their terms. Make it special, a secret pirate internet just for them.

Give your kids a phone asap and train them to use it as a tool and a weapon. Let them call grandma or whatever, family friends, foreign heads of state. Give them a curated phone list. Call them. Send them pictures and stuff from your day. See if you can find them foreign penpals somehow. Help them learn to use it as a tool for community and communication

Fill their phone up with cool tools. I've got an astronomy program called stellarium, 9 different photo and video editing apps, a bunch of network analysis stuff, a radio scanner. There's tons and tons of weird, useful tools out there. Ai stuff that will id plants and bugs for you

teach them to hate. Kids understand right and wrong even if they're not always very good at it. Teach them how media is used by bad people to hurt workers. I think 8 or 9 is a good time to start in on behavioralism. Buy some rats, teach them to do tricks, show kids how there's no difference between making rats roll over for a yogurt drop and getting their schoolmates to sit for hours watching tiktoks. (Rats are also great for teaching kids about cancer and death. And definitely rats! Hamsters are insane little monsters. Mice are dumb. Guinea pigs are boring. Rats are very smart, very very social, more durable than most pocket pets, and i cannot stress this enough very social. They will love your kids and make them part of the rat social unit in a way other pocket pets cannot. They will genuinely enjoy playing with and engaging with your kids. I would advise getting all girls and looking for rescue rats than need homes). Teach them that it's a weapon and that the badguys want to use it to hurt them and show them how the weapon works.

Trust your kids omg trust your kids. The little bastards are smart, they know stuff, they'll cheat and figure out how to get their own access and lie to you about it. They'll go to school and look up how to root your locked down parental controlled iPad and then steal it and watch stuff all night. Just assume that they're smarter and more canny then you and extend trust, let them make safe mistakes, be a safe resource and not a jailor.

Give them the sex talk as soon as they can talk and keep giving them the sex talk their whole lives. They're going to encounter a whole lot of porn at a frighteningly young age and there isn't much you can do to stop that, so make sure they're well armed with knowledge about sex, sexuality, consent, feminism, before they encounter it so they don't get blindsided and they know right from wrong going in. Teach them about misogyny and man-o-sphere shit before the encounter it.

Let them play whatever games their friends are playing, especially if it's complex shit like minecraft or whatever where they can build stuff. The children yearn for the mines, so many games these days are unlimited fantastical lego boxes with infinite legos. Hell, if you find a good game with lots of building and no mtx bullshit talk their friend's parents in to getting the same game, set up a private server, let them go nuts with their friends. Host lan parties like the days of yor. And let them play the dumb violent stuff with innapropriate violence and sex too if they want to. Just, you know, give them tools to understand when they go in. If they want to play shooters teach them squad tactics, or the geopolitics or cultural history behind the setting in the game. Teach them how network latency works. Break the game in to pieces, make it a machine they understand and control.

Idk, i guess what i'm getting at; your kids are going to be at war from the moment they have color vision and can coordinate their hands. You can't shield them from that war, they're going to be exposed to it constantly. There are countless stories about parents who tried to raise their kids without violent media only to find them playing swords with sticks. Kids start to internalize gender roles and media depictions of beauty from like, idk, sixish? You can't shield them from the war, but you can train them, give them weapons and armor and knowledge. Make them warriors, help them be strong.
