A Little Light in the Dark

From carved turnips to clay diyas, festival lights around the world offer young children rich sensory learning and a deep sense of belonging.

The moment the sun sets, a small flickering light can instantly capture a young child’s entire attention. Across cultures around the world, letting children light or carry a lamp in the dark seems to be a universally shared instinct.

Whether it is the Räbeliechtli (turnip lantern) processions in Switzerland, the clay diyas of Diwali in India, or the paper lanterns of the Mid-Autumn Festival, these illuminated traditions are much more than beautiful ceremonies. They are precious moments for children to make sense of the physical world and build a deep sense of security.

Learning between the fingers

The pioneering Swiss educator Johann Heinrich Pestalozzi famously advocated for learning through the "head, heart, and hand." For young children, the magic of a festival of lights usually begins right at their fingertips.

In many Swiss towns and villages, as late autumn turns to winter, children sit with their families to craft Räbeliechtli. They use small spoons to carefully scoop out the inside of a purple-topped turnip, carving stars, moons, or animals into its skin. When a candle is placed inside, the translucent root glows warmly from within. Similarly, shaping a clay diya for Diwali or folding crisp paper for a Mid-Autumn lantern engages a child’s senses completely. As they touch damp clay, firm vegetables, or delicate paper, they practice fine motor skills and hand-eye coordination. Working with these real, tactile materials is one of the most effective ways for a growing brain to understand the physical world.

Little scientists in the light and shadow

Walking outside with a lantern is an impromptu natural science lesson. The renowned developmental psychologist Jean Piaget observed that children construct knowledge actively by experimenting with their environment.

When a child holds a lantern in the dark, light streams through carved gaps to dance on the pavement, and their own shadow stretches long and tall against a wall. This immediately sparks curiosity. Where does the light come from? Why did my shadow get so big? When a child watches a shadow shift, or asks their little companion Sparkie, "Why is my shadow following me?", they are acting as early scientists. By moving the light source and observing how the shadow changes, they are naturally testing hypotheses about optics and spatial relationships.

A shared rhythm in the night

The dark can be intimidating for young children, but the glow of festival lights transforms this experience. Psychologist John Bowlby’s attachment theory highlights the importance of a "secure base." When a child is surrounded by the warmth of their family, holding a parent's hand while walking in a community lantern parade, that secure base extends from the home out into the wider world.

Amidst shared songs and flickering lights, the unknown night turns into a safe, magical space. Children feel a deep sense of belonging, learning that with the right support, they can step bravely into the dark.

Three small things to try this week

• Craft a jar starlight: Find a clean, empty glass jar and help your child paste overlapping pieces of colored tissue paper on the outside. Once it is dark, drop in a battery-operated LED tea light and watch how the colors glow.
• Post-dinner shadow theater: Turn off the main lights in a room and turn on a single flashlight. Let your child use their hands or small toys to cast shadows on the wall. Encourage them to move the toys closer to and further from the light to see what happens.
• A twilight walk: On a mild evening, head out for a walk around your neighborhood carrying your homemade lantern. Prompt your child to listen to the quiet sounds of the night and observe how their little light illuminates leaves, pebbles, and the path ahead.
