Becoming a mother changes everything. Your body, your brain, your relationships, and your sense of self. There’s a word for that and it’s been around for decades yet up until now we have rarely used it. It’s time we started.
You’ve heard of adolescence – that turbulent, identity-shifting passage from childhood to adulthood. But have you heard of matrescence?
If you haven’t, you’re not alone. Despite being coined by medical anthropologist Dana Raphael in the 1970s, the term has only recently begun entering mainstream conversation. And yet, for the millions of women who have felt lost, overwhelmed, or utterly unlike themselves after having a baby, this single word can feel profoundly validating.
Matrescence is the developmental process of becoming a mother. It describes the physical, psychological, emotional, hormonal, and social transformation that occurs when a woman transitions into motherhood.
And it is every bit as significant as adolescence.
So why has no one told us about it?
The Word That Changes Everything
The word matrescence comes from the Latin mater (mother) and mirrors the linguistic structure of adolescence. Just as adolescence marks a fundamental shift in identity, biology, and social role, so does matrescence.
Dr. Alexandra Sacks, a reproductive psychiatrist who brought the term back into public consciousness in her 2018 TED Talk, describes matrescence as “a developmental shift that’s as powerful as puberty.” Yet unlike puberty, which is widely discussed, prepared for, and culturally acknowledged, matrescence has largely been invisible, both in medicine and in society.
This invisibility has a cost. When women don’t have a framework to understand what is happening to them, they often internalise the struggle as personal failure. They wonder: Why don’t I feel the way I thought I would? Why am I grieving the person I used to be? Why is this so hard?
Matrescence gives those feelings a name and more importantly, a context.
The Physical Changes of Matrescence
Pregnancy and childbirth are the most visibly physical events in many women’s lives. But the physical changes of matrescence extend far beyond a changing body shape or recovering from birth. We tend to prepare for birth and for everything that our new little one needs but we rarely prepare for ourselves and what we need in the postpartum period.
The brain physically rewires itself.
Research published in Nature Neuroscience (2016) found that pregnancy causes lasting and significant structural changes in the brain – a process sometimes called neuroplasticity of motherhood. Grey matter in regions associated with social cognition, empathy, and theory of mind becomes more refined. This is not “baby brain” or cognitive loss; it is the brain restructuring itself to help a mother attune to her child’s needs.
Hormones transform overnight.
During pregnancy, oestrogen and progesterone reach the highest levels they will ever be in a woman’s life. After birth, they plummet. This hormonal cliff edge happens within hours of delivery and is one of the most dramatic hormonal events the human body can experience. YET, it’s rarely discussed outside of the context of postnatal depression.
These hormonal shifts affect sleep, mood, appetite, libido, memory, pain tolerance, and emotional regulation. They are not weaknesses. They are biology.
The body is permanently changed.
Many women experience lasting physical changes that are never quite explained to them before they happen: changes to joints and ligaments, shifts in shoe size, alterations in skin, hair texture, and even fingerprints. Abdominal muscles separate (diastasis recti), pelvic floors are fundamentally altered, and chronic pain or fatigue can persist for months or years.
Understanding these changes as part of a developmental process – rather than signs that something has gone wrong – can be transformative.
The Personal and Psychological Changes of Matrescence
Perhaps the most disorientating aspect of matrescence is what it does to a woman’s sense of identity.
The identity shift is real and it’s profound.
Psychologists call it identity disruption. A woman who has spent decades building a career, a personality, a social life, and a self-image suddenly finds that none of these reference points feel entirely reliable. She is the same person she was, and yet she is not.
This is not pathology and it’s not postnatal depression (though the two can co-exist). It is the natural, if deeply uncomfortable, process of integrating a new self with the old one.
Ambivalence – that push and pull of conflicting emotions – is normal and expected.
One of the most taboo aspects of new motherhood, and the one I bang on about the most, is the ambivalence (the mixed feelings) many women feel. Loving a baby and simultaneously mourning your former life, your freedom, your spontaneity, your sleep, your body, or your career is not a sign of being a bad mother. It is a sign of being a human being in the middle of an enormous (this word does not do the size justice) transition.
Dr. Sacks writes that when women are not told that ambivalence is a normal part of matrescence, they often interpret their conflicted feelings as evidence that they are failing. This can compound suffering unnecessarily.
Mental health is part of the conversation.
Postnatal depression affects approximately 1 in 5 women in the UK. Postnatal anxiety, OCD, and birth-related PTSD are also common and significantly underdiagnosed. Understanding matrescence does not replace seeking support for perinatal mental health difficulties, but it does provide a compassionate framework within which these struggles make sense.
If you are finding the transition to motherhood particularly difficult, you don’t have to navigate it alone. Support for new mothers is available, and recognising what you’re going through is the first step.
The Relationship Changes of Matrescence
Matrescence does not happen in isolation. It ripples outward – into partnerships, friendships, family dynamics, and professional relationships.
The relationship with a partner is tested.
Even the strongest relationships are strained by the arrival of a baby. Sleep deprivation, changed roles, shifting intimacy, financial pressure, and differing parenting approaches create fault lines that many couples are not prepared for.
Research consistently shows that relationship satisfaction drops for most couples in the first year after having a baby. This is not a sign that the relationship is failing, it’s a sign that two people are going through their own enormous transitions simultaneously. Many partners experience their own version of identity shift.
Importantly, the mental load – the invisible cognitive and emotional labour of managing a household and child – falls disproportionately on mothers. This imbalance can breed quiet resentment that erodes connection over time if left unaddressed.
Friendships change – often painfully.
Friendships made before motherhood may feel suddenly strained. The woman who used to stay out late, travel spontaneously, or call to debrief after a difficult day at work is now someone whose world has narrowed and deepened in ways that are hard to articulate to those who haven’t experienced it.
Meanwhile, friendships formed in the newborn haze – bonded over feeding groups and sleepless nights – can feel unexpectedly intimate. The social map is redrawn.
The relationship with extended family shifts.
Grandparents and in-laws suddenly become more present, for better or worse. Opinions about feeding, sleep, childcare, and parenting style emerge from people who previously kept their distance. Boundaries that were easy before may become harder to hold.
The relationship with work is renegotiated.
Whether a mother returns to paid work or steps back from it, her relationship with professional identity is fundamentally changed. For many women, their career was a central part of who they were. Matrescence asks them to renegotiate that.
For those who return to work, the guilt, the logistics, and the sense of being stretched across two worlds can be exhausting. For those who don’t, the loss of professional identity, financial independence, and adult stimulation can be equally challenging — and equally unspoken.
The Societal Changes Driving (and Ignoring) Matrescence
Matrescence does not happen in a vacuum. It occurs within a society that holds particular, and often contradictory, expectations of mothers.
The myth of the “good mother”.
Society tells women that motherhood is natural, instinctive, and deeply fulfilling. The result of this message is that if it doesn’t feel that way, something is wrong with you. This mythology is reinforced through media, social media, and even well-meaning family members.
The “good mother” ideal has shifted over time – from self-sacrifice to attachment parenting to “bouncing back” to work – but it has always been prescriptive, and it has always placed the burden of perfection on women’s shoulders.
Matrescence, by acknowledging that this is a developmental transition with real psychological and physical dimensions, pushes back against this narrative. It says: this is hard because it is hard, not because you are failing.
Maternal healthcare is under-resourced.
In the UK, the postnatal period is significantly under-supported. Women typically receive a six-week GP check – which often lasts six minutes – before being largely left to get on with it. There is almost no routine screening for birth trauma, no standardised support for identity disruption, and limited provision for perinatal mental health outside of crisis.
Across the developed world, maternal mental health receives a fraction of the research funding and clinical attention of other health areas, despite affecting enormous numbers of people.
The paid parental leave gap.
The structure of parental leave in the UK, while more generous than in some countries, still creates conditions where women are disproportionately likely to reduce or exit paid work after having children. The gender pay gap widens significantly after the birth of a first child, a phenomenon economists call the “child penalty.”
This is not just an economic issue. It shapes the psychological experience of matrescence profoundly. A woman who watches her earning power, career progression, and professional identity recede while her partner’s remains unchanged, is navigating not just a personal transition but a structural inequality.
Social media and the comparison trap.
Instagram mothers with glowing skin, organised nurseries, and apparent emotional equilibrium are not representative of matrescence. They are a curated highlight reel. And yet, for women in the middle of their own raw, messy, exhausting transition, social media comparison can reinforce the sense that everyone else is managing while they are drowning.
Matrescence, once understood, provides a kind of immunity to this. It says: that polished image doesn’t show the whole of someone’s transition. Your struggle is not uniquely yours.
Why Nobody Told You About Matrescence
There are several reasons this concept has remained underground for decades, and all of them are worth examining.
Medicine has historically centred the infant, not the mother. Postnatal care focuses on the baby’s development, feeding, and weight. The mother, if she is not visibly unwell, is largely assumed to be fine.
The language didn’t exist in popular culture. Words matter. Without a word for the experience, it was much harder to discuss, research, or validate.
Ambivalence and struggle are still taboo. A culture that idealises motherhood will always struggle to make room for its complexity. Admitting difficulty has often felt dangerous – as though it might call your commitment to your child into question.
Women have been telling each other in hushed tones for generations. The knowledge has always existed, passed between mothers, whispered in postnatal groups, shared in the dark during night feeds. But it has rarely been named, validated, or centred.
That is beginning to change.
What Matrescence Is Not
Understanding what matrescence is also means being clear about what it isn’t.
Matrescence is not postnatal depression — though PND can happen during matrescence, and the two share some characteristics. Matrescence is a universal developmental process; PND is a clinical condition requiring support and treatment.
Matrescence is not weakness. The difficulty of the transition is proportional to its magnitude, not to a woman’s resilience or capability.
Matrescence is not a reason to dismiss genuine mental health difficulties. If you are struggling significantly, please seek support.
Matrescence is not only relevant to biological mothers. Adoptive mothers, step-mothers, mothers through surrogacy, and same-sex parents who take on a primary caring role all experience versions of this transformation.
Living Through Matrescence: What Can Help
Naming the experience is the beginning, but there are also things that genuinely support women through this transition.
Being told it is normal. This sounds simple, but it is profound. Knowing that identity disruption, ambivalence, grief for your former self, and physical exhaustion are all expected parts of the process can reduce suffering significantly.
Being seen by a partner, friend, or professional. Matrescence is lonely when it is invisible. Connection, whether with a therapist, a postnatal group, or a trusted friend, makes it survivable.
Reducing the pressure to “bounce back.” Every aspect of the culture around new motherhood encourages women to return to their previous selves as quickly as possible. Matrescence suggests a different approach: integration rather than restoration. You are not going back. You are becoming someone new.
Access to support. Whether that is practical help, therapy, or information about what is happening to you – access to good support matters.
The Beginning of a Better Conversation
Matrescence deserves a place in antenatal education, in GP surgeries, in workplaces, in partnerships, and in public conversation. It deserves the same cultural acknowledgement we give adolescence. Which is to say: it deserves to be expected, prepared for, and met with compassion rather than confusion.
The transition to motherhood is one of the most profound things a human being can go through. It reshapes the brain, the body, the identity, the relationships, and the life of the woman experiencing it.
You are not falling apart. You are becoming more capable, more adaptable, more whole. If you embrace your matrescence.
