My daughter is always happy.
I find myself watching her sometimes and wondering why. She moves through the day so lightly. Reading her books, playing with her toys, jumping from one corner of the house to another, speaking in half-formed words that only she fully understands. There is a kind of joy that sits naturally on her.
Even nursery follows the same pattern. She may not be as excited when she is dropped off, but by the time I pick her up, she is back to herself. Smiling. Energised. As though the day has been kind to her.
She will be two in a few months, and I have noticed the same thing in other toddlers.
Their days are simple. A rhyme repeated over and over. Toys scattered across the floor. Random bursts of laughter. Moments of tears. Then laughter again. They cry, yes. Often and loudly. But not in the way we do.
Their tears do not carry stories.
A child cries because something is wrong in the moment. Hunger. Discomfort. Frustration. And once that need is met, the emotion dissolves almost immediately. There is no lingering weight. No replaying of events. No quiet suffering carried into the next hour.
They do not live in sorrow.
Somewhere along the way, that changes.
At a certain age, a child begins to understand the world. Or perhaps more accurately, begins to absorb it.
And with that comes a different kind of awareness.
You start to notice things that were previously invisible. How things work. What could go wrong. What has gone wrong. The quiet complexities behind everyday life. Bills that need to be paid. Relationships that are not what they seem. Outcomes that are uncertain. News that never seems to end.
Knowledge expands your world. But it also expands what you can worry about.
A child has no concern for how the lights stay on. No awareness of what is happening in someone else's home. No interest in who won or lost last night. Their world is small, and because of that, it is manageable.
As we grow, the world becomes larger.
And with that expansion comes weight.
It is easy to say knowledge is power. And it is.
But knowledge, without direction, can become heavy.
Because knowledge rarely sits still. It demands something. A response. A decision. A form of action. Or at the very least, space to be processed and understood.
When it is not given that space, it lingers.
And when it lingers, it accumulates.
You begin to carry things you were never meant to hold all at once. Headlines. Opinions. Possibilities. Comparisons. Half-formed thoughts that never fully settle. It builds quietly, until your mind feels crowded without you fully understanding why.
And when this happens repeatedly, day after day, it does something to you.
Not always in a dramatic way. Sometimes it is subtle.
A low hum of unease. A background noise of worry. A sense that something is always unresolved.
What you are feeling is not always the weight of your life.
Sometimes it is the weight of everything you have taken in, but not processed.
And in that sense, the difference between the child and the adult is not just responsibility.
It is accumulation.
The child experiences the moment and releases it.
The adult collects the moment, stores it, revisits it, and then adds something new on top.
And over time, that changes how you move through the world.
It makes you heavier.
Perhaps the lesson is not to reject knowledge. That is neither possible nor wise.
But to be more careful with it.
To ask, not just what am I learning, but what am I doing with what I know?
Is it leading to something? Is it being processed? Or is it simply being added to a growing pile in the background of your mind?
Because not everything needs to be carried.
And not everything deserves space in your thoughts.
There is something we can learn from children, not in their ignorance, but in their ability to release.
To feel fully, and then let go.
To return to the present without dragging yesterday into today.
And maybe that is why they seem so light.
Not because life is easier.
But because they are not holding more than they need to.
