This is one of the hardest conversations there is to have well, and it is hard for a structural reason: you are asking someone to hand over the thing that regulates their mood, in front of you, on request. Most adults could not do that either.
So the aim here is not a conversation that goes perfectly. It is a conversation that leaves the door open, because you are going to need to have it more than once.
The one thing that changes the odds: confiscation ends this evening's incident and teaches your child to hide the next one. Almost everything below follows from that.
Be curious, not prosecutorial
Ask what they actually do on there. Who they talk to. What is good about it. Not as a trap — genuinely. Some of it really is good: friendships, jokes, music, things they are making. A parent who cannot admit any of that has already lost the argument, because the child knows it is not all bad and now knows you are not being straight with them.
Get on the same side of the problem
“These things are built by professionals to be hard to put down, and I find it hard too.”
That is true, it is verifiable, and it turns the conversation into the two of you against a designed system. Compare it with “you are on that thing too much”, which is the two of you against each other, over something they cannot control on their own.
Do it yourself, and let them watch
Children calibrate to what is modelled, not what is instructed. A parent who has done their own detox is asking for something they have done. A parent who has not is issuing instructions from the sofa while scrolling, and the child can see it.
The course here is free. Doing it in front of them is the strongest argument available to you and it does not require you to win a single debate.
Watch it with them, at least sometimes
A meta-analysis of 88 studies found that being in the room, watching together and talking about what you are both seeing had a stronger protective effect than either encouragement or restriction. It is the best-supported thing any parent can do and it costs nothing but your evening. It is also, inconveniently, the least compatible with being busy.
Two sentences to say in advance
On sextortion: “If someone ever gets a photo of you and threatens you with it, my first move will be to help you. Always.” See why this matters.
On anything frightening: “If you see something online that scares you, you can tell me and nothing gets taken away.” If the price of telling you is losing the phone, they will not tell you.
Something to hand them rather than say
If your child is eight or older, Jonathan Haidt and Catherine Price's The Amazing Generation is written for children rather than about them, and it lands better than anything a parent can say out loud.
Michael has spent much of his working life online—and much of the rest of it trying to stop that technology taking over. He has thrown a phone into a lake, locked devices in boxes and experimented with long periods offline. He writes about what helped, what failed and how to keep the useful parts of digital life.
