“Am I safe? If I cry, will someone come? Can I explore the world without being afraid?”
These are some of the first questions a child asks without yet having words for them. They are “asked” through the body, through crying, through the gaze, through the search for an embrace, through the need to play and explore.
And the child’s brain learns what to expect.
The first years of life are a period of extraordinarily intense brain development. Neural connections form rapidly, and the child is not only learning how the world around them works. They are also learning what to expect from it.
When I am afraid, is there someone to protect me?
When I am in pain, is there someone who will notice and soothe me?
When I need help, can I turn to someone?
When I am happy, is there someone who will be happy with me?
The brain learns through relationship
A small child cannot yet regulate anxiety, fear or arousal on their own the way an adult can. They need an adult to help them settle.
The embrace, the voice, the gaze, the adult’s presence, their play together, the repetition of the same reassuring experience all work as a kind of external regulation. Little by little, what another person initially provides becomes something the child can develop within themselves.
Security, then, is not simply a pleasant condition of childhood. It is part of the environment within which neural and biological systems are organised — systems related to stress, attention, emotion, memory and threat detection.
When, by contrast, a child grows up repeatedly amid fear, stress, unpredictable reactions, neglect or abuse, their organism will have to adapt to that reality.
The brain is plastic and will try to adapt to the environment in which it is developing. It learns and readjusts through the relationships it exists within.
If the environment is constantly saying “watch out”, the alarm system can become especially sensitive. If it says “you never know what will happen”, vigilance can become a way of being.
When the body keeps waiting for danger
Sometimes the consequences of a chronic sense of insecurity appear through the body.
Neurologically, there are people who present with real and very intense symptoms — episodes that resemble epileptic seizures without being caused by epilepsy, difficulties with movement or speech, chronic pain, or intense fatigue and “brain fog” — while neurological investigations do not explain the symptoms in the way one might expect.
In some of these people there may be a history of significant stress or adversity in childhood. This does not mean that every difficult childhood experience leads to such symptoms, nor that every neurological symptom has a psychological cause. Symptoms always require appropriate medical assessment.
The brain and the body, however, are not two independent systems. A person’s history can also be inscribed in the way their nervous system reacts, regulates itself and perceives something as threatening. By this we mean something the person fears, or whatever they have learned to associate with danger, or something they feel they cannot manage or regulate emotionally.
A perfect parent is not required
Perhaps this is where one of the most important messages for parents lies.
Security does not mean a perfect childhood. It does not mean that the parent will never get angry, never be tired, never make mistakes, or that there will be no moments of disconnection.
A child does not need a perfect adult. They need a person who, most of the time, is there. Not always.
Someone who will hear their crying. Who will hold them. Who will play with them. Who will let them explore and will be available when they come back, without punishing them or becoming angry with them. Someone who can bear their big feelings without making them ashamed of them.
And when the relationship is disrupted — because inevitably it will be — repair can happen. Not withdrawal, punishment, disappearance or retaliation.
“I got angry with you, but I am here.”
“I frightened you, I am sorry.”
“Let’s find our way back to each other.”
These small moments matter more than we perhaps imagine.
Perhaps, in the end, what a secure caregiver offers is not only protection from fear.
It offers the child the freedom not to organise their whole life around it.
A child who feels there is someone to return to can more easily move away, play, try things, fail, learn, take risks, get to know the world. This security, initially provided by the parent, can over time be internalised by the child and become part of their own inner sense of safety and trust.
And perhaps this is one of the most profound things we can offer a child: not the promise that the world will never hurt them, but the experience that, when something difficult happens, they will not have to face it alone — and that they can always find their way back to safety.
Because the first years are not simply the time when a child grows.
They are the time when, through thousands of small everyday experiences, a child begins to learn what the world is like, what they can expect from others, and whether they can feel safe enough to be themselves within it.
