What is matrescence?
Why you’re asking
A friend mentioned it to me in 2022, two weeks before my first child was born. If there’s one thing I wish I’d at least read about, it was matrescence. Not to prepare, she said. Just to know it’s normal to feel how you feel.
I didn’t read about it. I had a baby, then another one, and only now, four years later, am I ready to look at the word properly. If you’ve just heard it from a friend, a podcast, or a stranger on the internet, and you’re wondering whether it’s worth your time: it is.
Here’s what it is
The simplest definition of matrescence is the process of becoming a mother. It is pronounced like adolescence, which is also where the word came from.
The word is older than you think. It was coined in 1973 by an American anthropologist called Dana Raphael, who studied how different cultures supported new mothers and noticed that Western culture, almost uniquely, had no language for what happens to a woman in the months and years after she gives birth. She borrowed the shape of the word from adolescence on purpose. The parallel is the point. Adolescence is the developmental transition from child to adult: physical, hormonal, psychological, social, identity-altering. Matrescence is the developmental transition from woman to mother. The same scale of change. The same length. The same disorientation. (Fun fact: Raphael also coined the word doula, which caught on faster.)
Then it disappeared for thirty-five years. The word sat largely unused until 2008, when a clinical psychologist at Columbia called Aurélie Athan came across it while working with new mothers who were struggling and finding nothing in the clinical literature that matched what they were going through. She picked it up again and has spent the last fifteen years rebuilding it into something serious. The Cambridge Dictionary added it in 2022.
The science has caught up too. A neuroscientist called Elseline Hoekzema has shown, across a series of studies starting in 2016, that pregnancy permanently changes the structure of a woman’s brain. Grey matter volume reduces in regions associated with social cognition — the parts that read other people’s needs and intentions. The changes are so consistent that a computer algorithm can identify a woman as having been pregnant from her brain scan alone, six years later. Her most recent study, published in early 2026, found that a second pregnancy changes the brain again in distinct ways. Each child rewires you slightly differently.
Less brain, but a smarter brain. The leading interpretation of all this is that the brain isn’t being depleted. It’s being fine-tuned, becoming more specialised, the way it does in adolescence. The neuroscientists call it efficiency. What it means in practice is that you have, structurally, become someone who can read a room differently. Whose stomach drops at a particular pitch of cry. Whose attention is permanently divided in a way it wasn’t before.
So matrescence is not metaphor. It is a real developmental stage, neurologically as well as socially, and it does not end when the postpartum period ends. Athan suggests it may last a lifetime.
Here’s how it shows up in real life
You bring your child to the crèche and the other kids start shouting at your child, your mom is here, your mom is here. For a second you don’t recognise yourself in the sentence. To them, you are a category. The category is who you are now.
You are at the doctor and a new GP looks at the chart and says are you mom? Not your name. Just mom. You think about how nobody else in your life would ever introduce themselves to you that way.
In a shop, you bump into someone you used to work with in the early years of your career. They look at the baby in the pram and their eyes widen into a smile. They say oh my god, you have a child, is this your baby? And you say yeah, I guess it is. It’s a strange thing to say about your own child. It’s also accurate. You are still catching up.
A word makes the thing it names visible. Without one, you keep thinking it’s just you.
