Matrescence: The Transformation No One Prepared You For

How motherhood reshapes your brain, body, and sense of self

Every morning used to begin in the same way. I would wake up, walk slowly to the kitchen, and make my coffee. I drank it while it was still warm, sitting quietly in the soft light coming through the window. Some mornings the sun warmed my face, and other mornings I watched the snow gathering on the streets.

Those mornings were slow and intentional, and they belonged only to me. Fifteen quiet minutes with breakfast and coffee, silence and presence, a small ritual that grounded me before the day began. They gave me the energy to stand up, get ready, leave the house, and step into my work and my ambitions. I did not know at the time how much of myself lived inside those quiet mornings. I did not know how deeply I would miss them.

I woke up one morning and realized that those mornings were gone. I no longer went to the bathroom alone. My body felt heavy and slow, as if I were dragging it through the day. The energy that used to come naturally had disappeared, and the coffee I poured every morning was almost always cold by the time I remembered it.

On paper, I was still the same person. I was ambitious, committed to my goals, and competent in my work. Yet it didn’t feel like that. Something inside me had shifted in a way I could not explain, and the person I used to be seemed to have quietly disappeared.

The ambivalence of becoming a mother

In its place there was exhaustion, worry, milk stains on my clothes, and a body that did not feel entirely like my own. At the same time there was also something else that had entered my life with an intensity I had never experienced before. It was the love I felt for my baby boy when he curled into my arms and breathed slowly against my chest. When he slept there, resting on me, a deep calm filled the room and for a moment everything else in the world felt distant and unimportant.

Before I became a mother, a friend once told me that parenthood meant that the highs would be higher and the lows much deeper. I now understand that this experience can also be described as ambivalence. Few experiences are as emotionally ambivalent as early motherhood. The sudden loss of autonomy can feel overwhelming when another human being depends on you for survival every minute of the day. Exhaustion can coexist with an intense longing for your child the moment you step outside the door. It is possible to feel grateful for becoming a mother and at the same time mourn the simplicity of the life that existed before.

Even though I tried to accept this ambivalence, I continued to feel uncomfortable with the depth of the change I was experiencing. I often wondered whether something was wrong with me. I asked myself whether I was failing as a mother. Humanity has been giving birth for millennia, so why did I feel so lost in this process? Surely other women must have navigated this transition with more ease.

If you have ever sat with a cup of cold coffee and wondered where the person you used to be has gone, you are not alone.

Matrescence

Over time I realized that what I was experiencing was not a personal failure but part of a profound human transition. The transformation that accompanies motherhood affects the brain, the body, the hormonal system, and the sense of identity. It is a developmental shift that has a name.

It is called matrescence.

The term was first introduced in 1973 by the medical anthropologist Dana Raphael, who proposed it as an analogy to adolescence. Just as adolescence describes the psychological and biological transition from childhood to adulthood, matrescence describes the transformation that occurs when a woman becomes a mother. It captures the profound changes in identity, biology, and social roles that unfold during this period.

I remember the moment I first came across the word. Something in me softened. The confusion and instability I had been experiencing suddenly appeared in a different light. What had felt like a personal failure was, in fact, part of a larger developmental transition that countless women experience.

The maternal brain

Research increasingly supports the idea that this transition is comparable in magnitude to puberty. During pregnancy and the months following birth, the maternal brain undergoes substantial remodeling. Studies have shown structural changes in regions associated with empathy, motivation, and social cognition. Some of these changes persist for years. Brain imaging studies have even demonstrated that researchers can distinguish women who have been pregnant from those who have not with striking accuracy long after the pregnancy has ended.

These biological changes are not abstract scientific observations. They shape daily experience. Many mothers notice that their attention becomes finely tuned to the cues of their infant. The sound of a baby’s cry can instantly capture attention, even from across a crowded room. Your brain begins to treat your baby as the most important signal in the world. What is sometimes dismissed as “mom brain,” the experience of forgetfulness or scattered attention, may reflect a brain that has reorganized itself to prioritize caregiving.

Hormones and emotional sensitivity

Motherhood also unfolds against the backdrop of one of the most dramatic hormonal transitions in human biology. During pregnancy the body sustains extremely high levels of hormones such as estrogen and progesterone, which drop rapidly after birth. At the same time hormones such as oxytocin and prolactin increase, shaping bonding and caregiving behaviors. The stress regulation system recalibrates as well, contributing to shifts in emotional sensitivity and mood.

No wonder this period can feel so intense. The emotional landscape of early motherhood is shaped not only by sleep deprivation and the responsibilities of caring for an infant, but also by profound physiological adjustments occurring within the brain and body.

The reshaping of identity

Alongside these biological changes there is another dimension that is often overlooked. Becoming a mother involves a reorganization of identity. Many women experience a sense of confusion about who they are becoming. Priorities shift. Values change. Questions about purpose and meaning arise with a new urgency. It can feel as though the previous version of the self has dissolved before the new one has fully formed.

Psychologists increasingly recognize this process as a developmental identity transition. The feeling of becoming a different person, the tension between autonomy and caregiving, and the ambivalence about leaving behind parts of a previous life are not signs of inadequacy. They are common features of this stage.

Yet modern societies rarely acknowledge the magnitude of this transformation. Mothers often sit quietly with their cold coffee without realizing how profoundly the structures around them shape their experience. The weight of caregiving responsibilities, the challenges of balancing work and family life, and the isolation that can accompany early motherhood all influence wellbeing. Cultural expectations about what a “good mother” should be add another layer of pressure. Many women find themselves trying to optimize every aspect of childcare while also holding themselves to impossible standards.

Recognizing matrescence

Recognizing matrescence offers a different perspective. It reframes the turbulence of early motherhood as part of a developmental process rather than a personal shortcoming. Lucy Jones explores this idea beautifully in her book Matrescence, where she describes motherhood not as a simple life event but as a profound metamorphosis that unfolds over years.

This perspective changed the way I understood my own experience. I began to see that the transformation was still ongoing, even after the birth of my second child. Each stage of motherhood seemed to invite another layer of growth and adaptation. The process was not about returning to the person I used to be. It was about becoming someone new.

Warm coffee again

Today my mornings are still busy, and life rarely unfolds with the quiet rhythm that once defined the beginning of my day. Yet the coffee is warm more often than it used to be. I sit with it when I can, sometimes in the same light that once filled the room years ago.

My brain has changed. My body still carries the echoes of pregnancy and breastfeeding. My life has been reshaped in ways I could not have imagined before becoming a mother. Yet the person I was has not disappeared. She has been woven into a larger version of myself that continues to evolve.

Understanding matrescence did not remove the challenges of motherhood. What it offered instead was language, perspective, and compassion. With the right words and the right support, this transition becomes easier to recognize for what it truly is: a powerful developmental transformation that expands who we are capable of becoming.

If you have ever sat with a cup of cold coffee and wondered where the person you used to be has gone, you are not alone. You are not broken. You are in transition.

I write about women’s health, matrescence, and the biological and emotional realities of the postpartum period. If this resonates with you, I would love to hear your experience or have you follow along as I continue exploring this transition.
