I used to be on social media a lot. Everything I saw made me believe it is rotten to the core, especially for young kids just figuring out who they are. I'm hard pressed to think of a single positive thing a child could gain from being on social media. Social media is set up for predation at it's core, everyone is playing the likes and followers game. No one likes your post or people attack you and now it's a vector for depression. It's an echo chamber. It amplifies the worst of us. It's full of pornography. Especially if you are a young teenage boy looking for it. So overall for me it's a net negative. I can talk to them about it when they are older, and in highschool
I think you're right about the objective quality of most of what's there. It's garbage. I have two girls under age of 5 but this topic will inevitably bubble up to the surface up to the age of 5. We actually pulled YouTube out of rotation for my older one because, much like you fear, one video slightly off the path played more than a couple times directed the algorithm down a black hole of nonsensical kids videos.
I'm telling myself - with time to go - that at I need to know what's going on in social media to help them understand what their friends might be allowed to do or not when we get to that point. And I'll monitor phones/iPads. Not yet sure about full bans on all of social media but we'll see where things are in that moment and evaluate.
Let me flip side this around: do your kids come to you about apps/social media/etc. with curiosities? Surely they hear about things. How do you redirect?
For me the worst part of social media is the echo chamber algorithm. You click on something, algorithm decides you like it and the next thing you know the earth is flat. You can't understand why anyone doesn't think the earth is flat because everywhere you go on social media you are being told it's flat. As far as you know everyone else is seeing the same content you are. Switch out flat earth with your negative item of choice.
Luckily enough my kids don't ask about social media yet although I do ask them every few weeks if their friends are on it. Some of them have YouTube primarily for video game tutorials. One of my kids friends has more but he is in a single parent household and pretty much left to fend for himself. Any games my kids play I generally playa couple times myself to validate. Their main game is Fortnite, groups of their friends play together.
Told my oldest he can have a phone next year when he starts middle school but it's my phone and he can use it as long as he follows the rules. Have not defined what those are yet for him or me.
I really think social media leads to depression, bullying and change in beliefs. I'd rather sit down with my kid when it's time, discuss with him why he can't have whatever I am saying no to and have him be mad at me for a bit rather than he gets involved in something detrimental.
I don't spank my kids so it's always come down to discussion. Has worked well so far but tomorrow is another day.
