Why "just playing" is the most serious work of childhood

June 11 marks the International Day of Play, established by the United Nations General Assembly in 2024 to champion and protect children's right to play. For many parents, play sounds simple — until the quiet pressure begins. Should I be teaching letters? Should I be doing more? Is this enough? Often, learning in childhood does not look like sitting still or completing a task with a clear outcome. Often, it looks like a mess.

A child pouring water from one cup to another. A baby dropping a spoon again and again. A toddler pretending a box is a car. A preschooler building a tower, watching it fall, and starting over. To adults, it may look like "just playing." For children, it can be one of the most important ways they explore the world.

Why does play matter in early childhood?

Play is recognised internationally as a child's right. UNICEF's 2024 International Day of Play guidance highlights play as essential to children's wellbeing and development.

This matters because executive function includes skills children will continue building over time — working memory, flexible thinking, and self-control. Play gives children a way to practise these skills before they can explain them.

• A child stacking cups is testing balance, timing, cause and effect, and persistence
• A child pretending to cook is using memory, language, imagination, and social understanding
• A child running, climbing, or dancing is learning what their body can do and how to adjust

Why does "optimising" play feel so tempting?

Many parents feel pressure to make every moment count. A toy should teach letters. A game should build vocabulary. An activity should prepare the child for school. That pressure often comes from love — parents want to support their child and give them the best possible foundation.

But when every moment becomes something to optimise, play can start to feel like another performance. The child is expected to produce learning. The parent is expected to direct it.

What children learn through open-ended play

Open-ended play gives children space to explore without one fixed answer. A block can become a tower, a phone, a bridge, or food for a pretend animal. A blanket can become a tent. A cardboard box can become almost anything.

For children ages 0 to 5, these skills are still developing. They are practised slowly, often through ordinary moments.

• Waiting for a turn A simple act that practises self-regulation, attention, and the understanding that others exist in shared space.
• Trying a different block when the tower falls Flexible thinking in action — adjusting a strategy based on what just happened, without a prompt from an adult.
• Remembering the rule of a simple game Working memory practice. The child holds the rule in mind while doing something else — a foundational cognitive skill.
• Changing the story when a playmate joins in Social flexibility, communication, and the early experience of collaboration — all without a structured lesson.

What is guided play?

The part parents often worry about is where they fit in. If play matters, should the adult step in — or step back? The answer is often somewhere in between.

Guided play happens when an adult supports the child's play without taking over. The child still leads, but the adult notices, follows, asks, extends, or gently supports the next step.

• A toddler stacks cups. The adult says, "You made it taller."
• A preschooler pretends a spoon is a microphone. The adult asks, "Who is singing today?"
• A child lines up toy animals. The adult says, "The small one is beside the big one."

What kinds of play support development?

Different kinds of play give children different opportunities to practise emerging skills — and they often overlap in the same moment.

What if play feels hard for parents?

Many parents do not lack the desire to play. They lack energy. After work, errands, appointments, caregiving, and household responsibilities, inventing a new activity can feel like one more task.

The good news is that play does not need to be elaborate to be meaningful.

A spoon. A box. A towel. A bowl of water. A song. A mirror. A soft ball. A familiar story told in a new voice. The value is not always in the object. Often, it is in the interaction, repetition, and curiosity it invites.

A final thought

When a child plays, they are not taking a break from development. They are exploring how the world works. They are testing what their body can do. They are practising attention, language, imagination, movement, and connection.

For parents, the work is not to turn every moment into a lesson. It is to protect space for play, notice what is happening inside it, and join when connection is needed.
