The Magic Years: Why Play is Serious Stuff!

Picture a six year old. She is lying on the kitchen floor, very seriously explaining to a wooden spoon that it cannot come to the tea party because it was rude to the fork. This is not messing around. This is not killing time. This is, if you look at it through the right lens, one of the most cognitively sophisticated things a small human can do.

We live in an age that is quietly suspicious of play. Especially unstructured play — the kind with no clear outcome, no app, no coach, no worksheet. We fill children’s schedules with enrichment and achievement, and then feel vaguely guilty about the unscheduled hours in between. I understand the impulse.

I want to invite you today, to remember the magic of play. Not just for our littlies, but for our big kids, teens (and even adults!). Drawn from decades of developmental research and a fair amount of time sitting on the floor with my own kids when they were little, and engaging in more sophisticated play as they have grown – I want to remind you of why play is not the opposite of learning. It is the engine of it.

What the science actually tells us

The evidence on play is not subtle. Research from Harvard, the American Academy of Paediatrics, and developmental psychologists around the world consistently shows that freely chosen, child-led play is one of the most powerful drivers of development across every domain - cognitive, emotional, social, and physical.

When children play, particularly imaginative and unstructured play, they are simultaneously practising language and narrative, building emotional regulation, negotiating social rules, tolerating frustration, experimenting with cause and effect, and developing a sense of agency and mastery. All at once. Without even trying. The brain during play is not idling, it is humming.

Stuart Brown, founder of the National Institute for Play, has spent decades studying play across species and cultures. His conclusion is unambiguous: play is not a luxury. It is a biological necessity. Animals that are deprived of play show impaired social development, reduced resilience, and difficulty reading the behaviour of others. Children are no different.

And yet, research from the US and Australia shows that children today have significantly less free, unstructured play than children a generation ago and the mental health statistics are trending in the wrong direction. That correlation is worth sitting with.

What happens inside a playing brain

Let me get a bit nerdy here, because I think it helps.

The prefrontal cortex, the part of the brain responsible for planning, problem-solving, impulse control, and emotional regulation, is not fully developed until the mid-to-late twenties. Play is one of the primary mechanisms through which it develops. Every time a child negotiates the rules of a game with a friend, resists the urge to cheat, or figures out how to build a tower that keeps falling over, they are literally training their prefrontal cortex.

Imaginative play, in particular, does something remarkable: it requires a child to hold two realities in mind at once. The spoon is a spoon and also a character at a tea party. This kind of dual representation is a significant cognitive achievement, and it is strongly linked to later literacy, mathematical thinking, and the ability to understand other people’s perspectives, what psychologists call theory of mind.

Physical play, running, climbing, rough-and-tumble, also plays a critical role in regulating the nervous system. Children who have regular opportunities for physical play show better attention, better impulse control, and better emotional regulation in the classroom. In short: letting kids run around is not a break from learning. It is preparation for it.

The magic of ‘nothing to do’

One of the most countercultural things I've been saying to so many parents lately is: boredom is a gift!

When a child says “I’m bored” and we resist the urge to immediately fix it and instead we hold steady and say “I’m sure you’ll figure something out” - something interesting happens (eventually!). After a period of protest and general grumpiness, most children find their way into play. Often creative, inventive, absorbing play that they generated entirely from their own imagination.

That process from boredom to curiosity to invention is not trivial. It builds what psychologists call intrinsic motivation: the ability to pursue things for the joy of them, not for external reward. It builds self-direction. It builds the capacity to sit with discomfort long enough for something new to emerge. These are skills that no worksheet can teach.

Maggie Dent, one of Australia’s most respected parenting educators, writes beautifully about the importance of unstructured outdoor play in particular, the kind where kids climb trees, get muddy, make up elaborate games, and manage their own risks. This kind of play, she argues, builds the resilience, physical confidence, and creative thinking that structured activities simply cannot replicate. I couldn’t agree more.

Play is also how children process the hard stuff

Here’s something that often surprises parents: play is not just how children learn about the world. It is how they make sense of their emotional world too.

Children often don’t have the words or the emotional vocabulary to process difficult experiences directly. But they will play them out. After a scary experience, a child might play hospitals, or act out a conflict at school through their toys, or repeatedly re-enact a scenario that frightened them, this time with a different ending. This is not accidental. It is the psyche doing exactly what it needs to do.

In child psychology, we take play very seriously for this reason. Play therapy exists because for children, play is the natural language of emotional processing. When a child is given space, safety, and time to play freely, they often work through things that words alone couldn’t reach. This is why we offer play therapy as part of our Manly Minds skills repitoire - it is hugely benefical and hugely important.

What this means practically for parents is that protective play - being available, providing safe and interesting environments, not over-managing or over-scheduling, is one of the most important things you can do for your child’s emotional health.

What you can actually do

Protect unstructured time. Not every hour needs a purpose. Leave space in the week for stretches of ‘nothing’, especially outdoors where possible. The boredom that precedes good play is part of the process.

Follow their lead. When you do play with your child, try resisting the urge to direct. Let them set the scene, assign the characters, make the rules. Your job is to be a willing participant, not a producer. Children light up when adults genuinely enter their world on their terms.

Protect risky play (within reason). Climbing, jumping, building precarious things - these are not accidents waiting to happen. They are children calibrating their own physical limits, building confidence, and learning to assess risk. Let them get a bit higher than feels comfortable. They are usually more capable than we think.

Don’t rush to the screen. When a child is bored or dysregulated, the screen is the path of least resistance, for them and for us. But screens provide stimulation rather than generating it. Whenever possible, give boredom a chance to do its work before reaching for the device.

Trust the mess. Mud kitchens, cardboard cities, cushion forts, nessy dining tables full of creations, things that take over the entire lounge room! These are signs of a child deeply at work. The investment in clean-up is worth it.

Remember

In a world that is increasingly anxious about outcomes and achievement, I think one of the most radical and loving things we can do for our children is to protect their right to play freely, messily, and without agenda. This is important for older kids too - to give them a chance to think, create and explore is one of the greatest gifts we can give our kids at all ages - even if they don't realise it initially, it is worth encouraging, facilitating and supporting!
