Because a child who hears the reason tends to carry the rule with them. “Because I say so” can buy peace in the moment, but rarely more than obedience while someone is watching. In 1967, researchers linked parents' explanations to children's empathy and moral development.

One sentence: “The rule is X, because Y.” Pick the strongest reason; give three and the good one drowns among the half-good. The reason can point to others: “When you pick up your phone at the table, grandma feels less important than a screen.”
From the article: “Because I say so” only lasts until you leave the room
Yes, just not in the moment. Give the reason once, calmly, and let the rule stand. The negotiation can come the next day, and it's worth the time: your child gets heard and practises arguing a case. A good enough argument can change your mind.
From the article: “Because I say so” only lasts until you leave the room
If you've explained the rule and the reason, you don't owe a second lecture. Answer calmly: “I hear you disagree, but the rule stays for now. Bring me a counter-proposal tomorrow if you like.” Your child has been heard, and there's a way forward.
From the article: “Because I say so” only lasts until you leave the room
Briefly. A three year old needs no lecture, just a short reason and a calm adult who follows through: “The iPad sleeps on its charger in the living room, so your brain gets to sleep too.” Same rule as they grow, just a fuller reason.
From the article: “Because I say so” only lasts until you leave the room
Same limit and same reason as when they were small, just in more detail. Our rules are written down, and when one frustrates my 15 year old, we put it on the table: is it outdated, or is she ready to regulate herself?
From the article: “Because I say so” only lasts until you leave the room
Rarely on its own. A ban without conversation can make the forbidden more tempting; psychologists call it reactance, and use tends to bounce back once nobody's checking. What seems to reduce risk is talking about the content, explaining, joining in and repeating it over time.
From the article: “Because I say so” only lasts until you leave the room
Not every time. If you usually give the reason, your child can take an “I don't have time for a speech now, so trust that I've got a good reason. We'll go through it tonight.” Say it every time, and your child stops believing it.
From the article: “Because I say so” only lasts until you leave the room
When it's urgent, like a child chasing a ball towards a road and you shout “Stop!” They stop first, and you talk it through afterwards. The deal that the reason reliably comes later is what makes “stop” work on the day it counts.
From the article: “Because I say so” only lasts until you leave the room
Possibly. Try giving each rule's reason in one sentence. If it won't fit, the rule may be a habit from your childhood. “Don't play with your food” may be about food not going to waste. The rule gets smaller, but truer and easier to accept.

Often because it was said once, while everything else your child meets repeats itself. The feed, adverts and friends say their piece many times a day, and what's repeated with gaps in between sticks. Repeat it calmly and often, spread out over time.
From the article: “Yeah yeah, I know”: repetition that helps kids
Yes, when the nagging is knowledge with a reason attached, repeated calmly and spread out over time. Repetition is one of the most solid findings in memory research: what comes back again and again sticks. Criticism, by contrast, survives almost no repetition.
From the article: “Yeah yeah, I know”: repetition that helps kids
More than you'd think, with gaps in between. Knowledge repeated over weeks is remembered far better than the same thing delivered in one go, across several hundred studies. Ten repetitions in one evening count as one. Once a week for ten weeks counts as ten.
From the article: “Yeah yeah, I know”: repetition that helps kids
Carry on, calmly. A child who knows exactly what you're about to say already has your sentence in their head, so I read it as a receipt: message received, currently being processed. Said with half a smile, it's often a running joke you share.
From the article: “Yeah yeah, I know”: repetition that helps kids
Often because the nagging has become criticism. “You're on your phone again” survives almost no repetition, while knowledge like “your brain needs breaks with no input” can take a hundred. And bring the reason every time, since rules without reasons tend to breed resistance.
From the article: “Yeah yeah, I know”: repetition that helps kids
Some repetition is probably unavoidable, but it can be honest and varied. Tell your child: “I'm going to repeat this until it sticks, then I'll stop nagging.” Keep the core message and change the wrapping: the car version, the dinner version, the one-liner.
From the article: “Yeah yeah, I know”: repetition that helps kids
Give the nagging an off switch your child controls. Say something like “the day I see you doing it without a reminder, I'm done nagging about it.” Then your child knows what it takes, and the goal becomes knowledge they own.
From the article: “Yeah yeah, I know”: repetition that helps kids
Largely because they repeat themselves. What we meet often becomes familiar, and what's familiar feels true and safe. Advertising and algorithms have built a business model on messages needing many meetings before they stick. The same mechanism is there for you at home.

Yes, a little boredom is probably good for them. When nothing is happening, the brain switches on a network of its own that tidies memories, rehearses the future and incubates ideas. A child who gets to be bored is practising being in their own head.
From the article: You're bored? Good!
It changes jobs rather than resting. A network researchers call the default mode network works harder when you're doing nothing in particular: sorting memories, running through plans and conversations, letting ideas mature. It uses roughly as much energy as solving maths problems.
From the article: You're bored? Good!
The research suggests so, though the experiments used adults. People given a dull task during a break came back measurably more creative than those who worked through it or simply rested. Boredom seems to tip the brain into daydreaming, and the daydreaming does the work.
From the article: You're bored? Good!
Ideally something that leaves the boredom unanswered, no activity suggestions. Try “Lovely, that means something's on its way.” Add a short why: “Your brain has a work mode that only switches on when you're a bit bored. That's when it comes up with new ideas.”
From the article: You're bored? Good!
Yes, it can be. The research isn't an argument for banning screens in the car. At our house I still sometimes say no to music on long journeys, and once the complaining dies down we often get conversations and nonsense we'd never have had otherwise.
From the article: You're bored? Good!
A break from the sound is probably wise. The brain tidies memories and incubates ideas only when nothing is playing. With a podcast from waking and music on the school run, it rarely gets the chance. One sound-free hour a day can help.
From the article: You're bored? Good!
Let the boredom sit for a bit. Fixed input-free times help: no screens, no podcast, no music. Ours are the first hour after waking, the last hour before bed and every meal. The complaining usually dies out, and what follows is often surprisingly good.
From the article: You're bored? Good!
Because sitting alone with your thoughts is uncomfortable for many of us. When researchers asked people to do just that for a quarter of an hour, plenty preferred giving themselves small electric shocks. The same discomfort has us reaching for a podcast or the phone.
From the article: You're bored? Good!
More than anything you say. Kids do as you do. Queue at the checkout with your phone out and they learn that spare minutes are for filling. Pick one regular waiting situation where the phone stays in your pocket. They'll notice without being told.

More than you do, and often more than a busy family week allows. A preschooler needs 10 to 13 hours, a school-age child 9 to 11 and a teenager 8 to 10. The best move is a fixed bedtime with room for enough sleep.
From the article: The science of good sleep
Children build their brains while they sleep, so they need more of it than adults do. Deep sleep repairs the body and fixes the day's learning; dream sleep processes feelings and impressions. A child who has slept too little finds it harder to learn.

Ideally, yes. The body clock settles when the days look alike. Two extra hours on Sunday feel like flying two time zones west, with the flight home due Monday. Wake-up time matters most, so try not to shift it far at the weekend.
From the article: The science of good sleep
Because the body clock shifts later in the teenage years. Teenagers get sleepy later, need 8 to 10 hours, and school drags them up before the body is ready. Sleeping in at the weekend makes Monday even harder. Spare them a little extra sympathy.
From the article: The science of good sleep
I'd recommend a screen-free hour, with phones sleeping outside the bedroom. Bright light near the face holds back melatonin, so the body waits to get sleepy. In one experiment, reading on a glowing tablet delayed melatonin by about an hour and a half.
From the article: The science of good sleep
Yes, because it cools you down afterwards. Core temperature must drop about a degree before sleep. The warmth opens the skin's blood vessels, so heat escapes faster once you're out. Shower about an hour before bed; in studies, people fell asleep almost ten minutes faster.
From the article: The science of good sleep
Around 18 degrees, a little cooler than most homes. The body has to cool down to fall asleep, and an overheated room is a common reason children lie tossing and turning. Air it before bedtime; it should feel slightly cool under the duvet.
From the article: The science of good sleep
Ideally early in the day. Caffeine has a half-life of five to six hours, so half of a 3pm coffee is still in you at 9pm. In one study, caffeine six hours before bed measurably worsened sleep. Same arithmetic for a teenager's energy drink.
From the article: The science of good sleep
Try dropping the demand to sleep. “Go to sleep now, or you'll be tired tomorrow” teaches a child to lie there monitoring whether sleep is coming. Something like: “You don't have to sleep. Just lie here and rest, and sleep will come by itself.”
From the article: The science of good sleep
A light evening snack is fine; it's the big, late dinner that can cost you some sleep, since your body is still digesting. In one study, adults who ate within three hours of bedtime woke during the night more often than those who ate earlier.

Not long. Facebook opened to everyone over 13 in 2006, the iPhone arrived a few months later, and at that point not a single study existed on what social media does to a teenager over time. The big studies only came a decade later.

Mostly luck, with your inner life and your friends playing a part. The apps are built to a recipe for holding our attention, and plenty of us parents still scroll in bed at one in the morning. That says nothing about being strong or weak.
From the article: We were the experiment: our kids are round two
The apps are stronger, at least. The ones children meet today have been sharpened by twenty years of measuring what keeps us in the feed; what we met in 2006 were student projects. What helps is known now, though, which it wasn't for us.
From the article: We were the experiment: our kids are round two
It's more nuanced than the headlines. The big analyses find smaller effects than many expect, and much depends on how you measure. The most encouraging finding is that parents who talk with their child about screens and set limits together seem to make a difference.
From the article: We were the experiment: our kids are round two
Banning on its own seems to work less well than getting involved. Parents who talk about the apps, explain the rules and set limits together with the child are linked to less problematic use than parents who simply ban things. Guiding appears to work.
From the article: We were the experiment: our kids are round two
Yes, and you don't need to be the finished article first. Children do what you do, so what teaches them most is watching you work on your own habits: “I'm leaving my phone in the kitchen, or no reading is getting done tonight.”
From the article: We were the experiment: our kids are round two
Start with your own story. Tell them about the hour that vanished or the post you regretted. Children listen harder to “this happened to me” than to “this could happen to you”, and limits feel less shameful coming from someone who struggles too.
From the article: We were the experiment: our kids are round two
Give the rule a reason, ideally your own story. Decide the one thing you wish an adult had taught you as a kid, write it down, and hand it over as just that. A rule with a reason is easier to accept than one without.
From the article: We were the experiment: our kids are round two
Ask for a tour. Pick the app your child uses most and you understand least, and let them show you what's fun and what turns up in the feed. One tour teaches you more than the theory, and your child sees you being genuinely curious.

Because irritation rests on an expectation that isn't being met, and home has the most expectations per square metre. Most we've never put into words, and with our kids we often set them by what we ourselves can do, years before the child can.
From the article: Why do I get so irritated with my kids?
Irritation rests on an expectation that isn't being met, anger on a demand, and disappointment on a wish. If what you feel is irritation, a wish has become an expectation, and the expectation is yours. So you can check whether it fits your child's age.
From the article: Why do I get so irritated with my kids?
Less than we think. A four year old tidies up with you. A nine year old remembers her plate with a reminder. A fourteen year old remembers it herself, but not every day. Everyday things only. If someone is unkind to your child, speak up.
From the article: Why do I get so irritated with my kids?
Rarely because they don't want to. Remembering to do something later, while something else is more interesting, is a skill of its own that develops through childhood. Working memory grows steadily from 4 to around 14, so a forgotten chore is mostly lack of room.
From the article: Why do I get so irritated with my kids?
Because breaking off something the brain is fully absorbed in, on command, uses the part of the brain that finishes last. That's an adult expectation. If you say in advance when the round has to end, with a small buffer, your child often manages it.
From the article: Why do I get so irritated with my kids?
There are four ways: try to change your child, change your own expectation, leave the room, or stay irritated. The second is the strongest. Look for the sentence that starts with “I was expecting”, and check whether it's set at adult level.
From the article: Why do I get so irritated with my kids?
Try naming it as a wish: “I wish you'd remember to put your plate in, but I'm not irritated or angry.” It's hard to get angry about something you've just called a wish, and your child sees an adult sorting out their feelings.
From the article: Why do I get so irritated with my kids?
Because repetition is how children learn, and remembering to do something later matures right through childhood. Until your child does it unprompted, the reminder is often part of your job. Said as a wish, even for the fortieth time, nothing in you has to escalate.
From the article: Why do I get so irritated with my kids?
Yes, ideally the same day, because your child learns from it: “I got irritated, and it wasn't your fault. I expected you to remember the plate by yourself, and that's maybe too much for a nine year old. I'll keep reminding you, without being cross.”
