I'm skint and my teenager doesn't have access to most social media.
He has a smart phone, with WhatsApp. No TikTok, no insta, no Snapchat, no FB, no youtube. I can see what apps he downloads and have to approve them. I can also see how long he spends on what apps.
He is allowed to watch all his special interest YouTube videos on the TV in the living room. Often I'll sit down and knit with him and watch stuff he is interested in. So he isn't deprived of everything YouTube has to offer, he's just not allowed to sit on his own and watch whatever shite the algorithms throw at him!
We go out a lot. Dog walks, museums, the odd theatre trip, castles, nice gardens, that sort of thing. Free stuff mostly but obviously some of it does have a cost attached. The shit they want when they've seen it on YouTube ain't free either though! Stanley cups and wanky trainers etc... I'd rather spend the money we do have on things that actually enrich his life!
