Matrescence: The Becoming of a Mother, and Why Birth Is Its Threshold

This is a plain, grounded guide to what matrescence is, why so few women have heard of it, what actually happens during it, and why birth sits at its very center. Understanding it will not make the transformation smaller. It will make it feel less like something is wrong with you, and more like something ancient is happening exactly as it should.

• Matrescence is the process of becoming a mother: the physical, hormonal, emotional, and identity transformation of the transition into motherhood
• The term was coined by the anthropologist Dana Raphael in the 1970s, and revived more recently by researchers and writers including Alexandra Sacks, Aurelie Athan, and Lucy Jones
• Like adolescence, it is a whole developmental stage, not a mood. The ambivalence and disorientation many mothers feel are a normal part of it
• Pregnancy measurably reshapes the brain, which is part of why the shift feels so total
• Birth is the threshold of matrescence, the central passage from one identity into the next, which is why preparing for it as a rite of passage matters

Matrescence is the process of becoming a mother: the profound physical, hormonal, psychological, and identity change a woman moves through as she transitions into motherhood. The simplest way to understand it is by comparison. Adolescence is the passage from child to adult, and everyone accepts that it is messy, years-long, and identity-shaking. Matrescence is the passage from woman to mother, and it is every bit as significant. We simply were not given a name for it.

The word was coined in the 1970s by the medical anthropologist Dana Raphael, the same researcher who helped bring the word doula into common use. It stayed largely within academia for decades until the reproductive psychiatrist Alexandra Sacks brought it to a wide audience through her writing and a widely shared TED talk, the Columbia researcher Aurelie Athan advanced it as a field of study, and the writer Lucy Jones explored it in her 2023 book, Matrescence. Their work shares one message: this transition deserves to be named, understood, and honored.

Because our culture tends to focus on the baby, not the mother being born alongside it. The moment a woman gives birth, attention turns almost entirely to the infant, and the enormous internal event happening inside her goes largely unwitnessed. Most women reach for words to describe the ground shifting under them and find only clinical ones, like hormones or baby blues, that do not come close.

Naming matrescence changes that. It gives a woman language for an experience she was quietly sure she was failing at, and it tells her the truth: she is not falling apart. She is being remade.

Matrescence touches nearly everything at once. A woman’s body changes, her hormones surge and recalibrate, her relationships and priorities reorder themselves, and her very sense of who she is loosens and re-forms. Alexandra Sacks describes a defining feature of it as a push and pull, a swing between joy and grief, closeness and longing for the self she was. That ambivalence is one of the most misunderstood parts of early motherhood. It is not a sign of a bad mother or a broken bond. It is a normal feature of a normal transformation.

The change is not only felt. It is physical, and visible on a brain scan. A 2016 study published in Nature Neuroscience by Hoekzema and colleagues found that pregnancy reshapes the human brain, producing changes in grey matter that were still measurable at least two years later. Researchers compared it to the remodeling the brain undergoes in adolescence. Part of why matrescence feels so total is that, quite literally, you are not working with the same brain you had before.

If matrescence is the whole passage, birth is its threshold, the single most concentrated moment of the entire transformation. In the span of hours, a woman crosses from pregnant to mother, and she does not return the same person. This is what it means to call birth a rite of passage rather than only a medical event, and it is why preparing for birth as the sacred threshold it is can shape the whole beginning of motherhood, not just the day itself.

This is also why the fear so many women carry about birth is worth meeting before the day arrives. When a woman crosses the threshold braced and afraid, the crossing marks her differently than when she crosses it anchored and met. Tending the fear beneath birth is part of tending matrescence itself.

The weeks and months after birth are matrescence at its most intense. The fourth trimester is when the new identity is still raw and forming, when the body is recovering and the self is reorganizing all at once. Understanding that this tender, disorienting time is a developmental stage, not a personal failure, is one of the kindest things a new mother can know. It does not last forever, and it is not a sign that she chose wrong. It is the middle of a becoming.

You cannot skip matrescence, and you would not want to. What you can do is meet it awake rather than blindsided. Naming it is the first step, and it is a large one. Beyond that: let yourself feel the full range of it without judging the harder feelings, gather real support around you rather than white-knuckling it alone, and mark the passage in ways that mean something to you. Some women find that inner preparation for birth, the kind that clears fear and builds trust before labor, gives them steadier ground to stand on as the whole transformation unfolds. That is much of what Birth Reimagined is for.

A note of care: the ordinary ups and downs of matrescence are normal, but they are not the same as postpartum depression or anxiety. If low mood, hopelessness, intrusive thoughts, or distress feel severe or last more than a couple of weeks, that deserves the support of a qualified professional. Naming matrescence is not a substitute for care when care is needed.
