Throwaway for reasons that will become clear. My eldest is 13, she had a phone from about 5 which for a long time seemed like a perfectly fine decision - it wasn't this unobtainable shiny object that only grownups have access to, it was a boring thing with no games on it, so she never had that device addiction. We have all Facebook domains blocked on NextDNS, she has no desire for a Twitter account, or Snapchat or anything else. It helps that she has a rabidly anti-surveillance-capitalism parent who can talk through the real world meaning of having one of these accounts. These days she does have a few games on there, but none of that pay to unlock rubbish. We use Apple Screentime for what it's worth (it's not worth much), but have had to restrict device use to the ground floor of the house as it turned out recently that she'd been self harming and sharing photos of the results when using it in her room. I think that's stopped now, and I don't believe it's related to actually owning the device at all - just a conduit for sharing it. Overall I think our policies have been successful, but with retrospect I would have banned devices from bedrooms from the start.
