The Baby Before Birth

A human being does not begin to exist on the day they are born.

 

Developmental neuroscience, early developmental psychology and foetal psychiatry now describe how prenatal experience can leave biological, sensory and relational traces that contribute to the earliest foundations of psychological life.

 

From life in the womb, the foetus is already capable of memory. The developing baby is already a sensory being, receiving a wide range of information that is gradually registered and forms a kind of memory—not a conscious memory of events that can later be narrated, but an implicit, non-verbal memory.

 

This imprint is made up of rhythms, sensations, states of tension or calm, hormonal variations, physiological tone, sounds and movement. Together, these experiences gradually shape the way the nervous system perceives the world and learns to regulate itself.

 

In a sense, the baby begins to learn what a predictable or tense environment feels like, whether it is containing or unsettling, and gradually adjusts their reactivity in response to what they experience. They do not yet understand through words, but they perceive emotional climates.

 

The body and nervous system therefore register an early imprint that helps form an inner map of the world: What is the world like? Is it predictable or unpredictable? Containing or stressful? And what place is there for me within it?

 

It is a silent language made up of sensations and a felt sense of safety, already carrying, beneath the surface, essential questions: “Is there a place for me? Am I expected?”

 

A remarkably subtle form of communication

Scientific knowledge now shows that the baby is sensitive to the many physiological changes that accompany the mother’s emotional states. Hormonal variations, bodily rhythms, breathing, movement, vocal intonation and changes in muscle tone all provide information to which the baby is exposed.

 

Beyond these well-established mechanisms, some clinicians suggest that foetal receptivity may be even more subtle. Although this cannot yet be stated with scientific certainty, they sometimes observe that the baby appears to participate in an extremely fine form of communication with the mother’s inner world, as though sensitive to the emotional atmosphere in which they are developing.

 

Whatever the exact nature of this communication, one point remains essential: the baby grows within a relational environment whose variations they perceive in their own way, without yet being able to distinguish what belongs to them from what belongs to the adult.

 

Making sense of what is experienced

All of this sensory experience already constitutes a genuine language.

 

Beyond what the baby perceives, an essential question is how these earliest experiences will be integrated and how the adults around the baby can help them move through them.

 

Putting words to the experience of a developing baby in the womb offers a framework through which that experience can be organised, soothed and given continuity.

 

Words help connect sensations to something coherent: “This is what is happening.”

 

Without words, a rise in tension may be experienced as a total state: “The world is dangerous. I am in danger.”

 

Words introduce an essential distinction: there is an event, there is a feeling—and then there is an outcome. Tension can ease. Calm can return.

 

This simple narrative helps protect against the implicit experience of stress that feels both “without cause” and “without end”.

 

It also creates continuity within the baby’s developing story.

 

Speaking to the baby is a way of beginning the story of the relationship. It says: “You are already someone to me. I am speaking to you. I recognise you.”

 

In more difficult circumstances—bereavement, a medically complicated pregnancy, conflict, significant anxiety or any other form of adversity—words may also help ensure that the baby is not left alone with an experience they can feel but cannot yet understand.

 

A protective presence

Words addressed to the baby can therefore form a genuine psychological holding environment.

 

They help organise experience: “This is what you are sensing. It is not you. It will pass.”

 

This early process of making sense contributes to the development of an initial foundation of inner safety. The world becomes easier to understand, and the relationship already begins to feel like a place that can help the baby move through life’s changes.

 

Speaking to the baby is a little like lighting a small lamp in the half-dark: it gives shape to what is being felt.

 

A voice that gently names what is happening: “I am worried, but I am taking care of myself. You are safe. I am waiting for you” does more than communicate information. It communicates presence.

 

Words weave an early thread between the inner and outer worlds and already tell the baby: “You are not alone in what you are going through.”

 

How I support expectant parents

In my clinical practice, I support expectant parents when pregnancy is affected by difficult events, significant anxiety, bereavement, assisted reproductive treatment, a medically complicated pregnancy, trauma or any situation that weakens the mother’s or the couple’s sense of safety.

 

The aim is not to create a perfect pregnancy, but to offer parents a space in which their emotions can be welcomed, understood and given meaning, so that they do not remain alone in carrying the weight of this period of transition.

 

Caring for the pregnancy also means caring for the bond that is already forming with the baby.

 

It means supporting the birth of a relationship before the child is even born.
