My mother could not tell you where I was between about nine in the morning and whenever I got hungry. Not vaguely — genuinely could not have told you, on most Saturdays of my childhood, which of about four fields I was in.
This wasn’t neglect. It was the standard arrangement. Everyone’s mother didn’t know where they were. You went out, you found whoever else was out, and the group did whatever the group did until someone’s mum shouted from a doorway. In the course of that you climbed things, fell off things, ran without noticing you were running, and arrived home filthy and exhausted having done what a modern parent would call four hours of vigorous physical activity and what we called being outside.
Nobody organised it. Nobody drove anyone anywhere. There was no kit.
That arrangement has more or less ended in a single generation, and I don’t think we’ve properly reckoned with the consequences — including the fact that we’ve responded to its disappearance by inventing an elaborate replacement that works considerably less well.
The great substitution
Here’s what happened, roughly. Free-range childhood roaming contracted sharply — for a mix of reasons involving traffic, perceived stranger danger, shrinking tolerance for risk, screens, and the simple fact that if no other children are out, yours won’t be either. It’s self-reinforcing: the fewer kids outside, the less reason for any individual kid to go out.
And into that gap came organised activity. Clubs. Sessions. Coaching. Fixtures. Kit that gets outgrown in a season. A calendar of appointments that parents drive to, wait at, and drive back from.
On paper this looks like a straight swap, possibly an upgrade — actual coaching, proper facilities, structure. In practice it’s a substitution with at least four problems.
It’s rationed by money and by parental time. Roaming was free and required nothing from adults. Organised sport costs, sometimes a lot, and consumes an evening. That means access now tracks household resources in a way it didn’t, which is one reason activity levels in children now vary by circumstance far more than they used to.
The volume is far lower. A ninety-minute session, twice a week, is roughly three hours. A single Saturday of unsupervised outdoors could exceed that on its own. And in a coached session a meaningful chunk of the time is standing in a queue, listening to instructions, or waiting a turn.
It’s selective, and it selects early. Organised sport sorts children into good and not-good remarkably fast, and the not-good ones learn a lesson about themselves that tends to stick for thirty years. Free play doesn’t do this nearly as brutally, because the rules get adjusted on the fly to keep the game going — which is, when you think about it, an extraordinarily sophisticated social technology that children invented without adults.
It teaches that movement is an event. This might be the deepest cost. A child who plays out learns that moving is simply what bodies do. A child whose entire physical life happens in scheduled sessions learns that exercise is a bounded thing you attend, at a time, in specific clothes, supervised by a professional. That’s the adult gym relationship, installed at eight.
PE, and the thirty-year hangover
Ask adults who describe themselves as “not sporty” where that came from, and a startling number will produce a specific memory from school. Being picked last. Cross-country in the rain. Being made to do something in front of everyone that they couldn’t do.
School PE, in its traditional form, had a design flaw that’s obvious in retrospect: it was largely built around competitive team sport, which is excellent for the children who are already good and mostly humiliating for those who aren’t. The kids who most needed to develop a positive relationship with movement got the version most likely to put them off it permanently.
I know a woman in her forties who genuinely believes she “can’t run.” She can. She’s perfectly healthy. What she actually can’t do is stop feeling fourteen and last, and that feeling has cost her three decades of a thing she might have enjoyed.
If you have children, this is worth knowing about, because it means the emotional content of their early experiences of movement matters far more than the physiological content. A child who arrives at twenty with the belief that they’re an active sort of person will figure the rest out. A child who arrives with the belief that they’re rubbish at sport will spend their twenties avoiding it.
What actually works, according to people who study it
The research on children’s activity is less prescriptive than you’d expect, but a few things come up repeatedly.
Parental behaviour matters more than parental instruction. Children of active parents are substantially more likely to be active themselves, and this seems to be about modelling rather than encouragement. Telling a child to go outside while you sit indoors is a much weaker intervention than going outside with them. Slightly annoying, but there it is.
Active travel is the biggest available lever. Walking or cycling to school is the single largest chunk of routine daily movement most children could have, and it’s declined enormously. If it’s possible where you live, it beats almost any organised alternative, because it happens five days a week, forty weeks a year, without anyone treating it as exercise.
Variety beats specialisation, especially young. Early specialisation in a single sport is associated with higher injury rates and higher dropout. Children who do lots of different things develop a broader movement vocabulary and are more likely still to be doing something at twenty-five.
Enjoyment predicts continuation better than competence does. The child who’s mediocre and loves it will out-participate the child who’s good and doesn’t, over a lifetime, by an enormous margin. Which means the thing to protect fiercely is whether they like it.
Risk is not the enemy. There’s a growing literature suggesting that risky play — heights, speed, rough and tumble, tools, getting a bit lost — does real developmental work, and that removing it doesn’t just cost fitness but appears to cost something in emotional resilience too. Children need to occasionally frighten themselves in a manageable way. The scraped knee is not a failure of supervision.
Two things to avoid saying
There’s one area where I’d be unusually careful, and it’s about how bodies get talked about in front of children.
Don’t make it about weight or appearance. Ever, really — not about theirs, not about yours, not about anyone’s on the television. The evidence here is fairly clear that weight-focused talk directed at children tends to backfire, damaging both their relationship with food and their relationship with movement, and it makes exercise into a punishment for the body rather than a thing the body does. Children who hear a parent criticise their own body learn the framework and apply it to themselves.
The alternative framing is capability. Not “this will help you lose weight” but “look how far you got,” “you climbed the whole thing,” “you were faster than last time.” Bodies as instruments that do things, not objects that get assessed. It costs nothing and it’s a completely different childhood.
And don’t turn it into a performance you’re invested in. The touchline parent shouting instructions is a cliché because it’s common, and the effect on children is well documented and uniformly bad. The moment a child perceives that their sport is something they do for you, the enjoyment — which was the whole point — is gone.
