Your Body Already Knows: Trusting Instinct Through Pregnancy, Birth, and Beyond

Something ancient happens when you pick up a crying baby. Before you've had a single conscious thought about it, your arms already know what to do — how to hold, how to sway, how close to bring them against your chest. This isn't learned. It's built in, the same wiring that slows your own breathing when someone you trust pulls you into a hug, or drops your shoulders when a warm hand rests on your back during a hard moment. Long before we had language for it, we had this: bodies calming other bodies. Nervous systems finding safety inside each other.

That quiet biological event has a name — co-regulation — and it sits underneath almost everything I want to walk through with you here: instinct, birth, attachment, and the strange, modern problem of learning to trust yourself in a world that hands new parents a hundred competing opinions before their baby is even a day old.

The Loudest Voices Aren't Always the Right Ones

Pregnancy has a way of making everyone an expert on your body except you. Relatives, hospital pamphlets, parenting forums, influencers, even pediatricians trained a generation apart from one another — all arriving with certainty, and often contradicting each other completely. It's enough to make you doubt the one voice that actually knows your baby: yours.

It's worth remembering that expert and right have never been the same thing. Nearly a hundred years ago, one of the most influential psychologists in America, John B. Watson, built his career telling parents that affection was a liability. His bestselling parenting guide warned against too much holding, too much kissing, too much comforting — a baby's cries, once fed and dry, were something to condition away, not respond to. An entire generation of Western parenting absorbed that advice.

Of Watson's four children, three attempted suicide as adults. One, his son William, did not survive it. It's impossible to know exactly what caused what in any one family. But it's hard not to notice the distance between the theory and the outcome — between a man who insisted children didn't need tenderness, and what happened to the children who didn't get enough of it.

I don't share that to frighten you. I share it because it's a useful measuring stick. When advice asks you to override what your body is telling you to do for your baby, it's worth asking what that advice is actually built on.

What Your Body Is Actually Doing When You Comfort Your Baby

Here's what Watson got backwards: humans aren't wired to self-soothe from birth. We're wired to co-regulate. When you're overwhelmed as an adult, the fastest way back to calm is rarely willpower — it's a hug, a hand on your arm, someone sitting close enough that you can feel them breathe. Touch lowers cortisol. It slows the heart rate. It tells your nervous system, in a language older than words, that you're not facing this alone.

Babies run on exactly the same system, minus all the coping tools we've spent decades building. When a baby cries and their hunger, temperature, and diaper are already taken care of, they are not manipulating you — they don't have the neurological hardware for strategy yet. They're asking, in the only language available to them, for regulation: for someone else's calm nervous system to lend them a sense of safety their own can't yet produce alone. Babies who reliably get that response don't become "spoiled." They grow into more secure, more emotionally steady adults — the research on attachment is remarkably consistent here.

You can watch a version of this instinct at work outside our own species. Neuroscientist Michael Meaney spent years studying rat mothers and found that pups who were licked and groomed heavily in their first days of life grew into calmer adults with a measurably different stress response — and, strikingly, those same pups grew up able to nurture their own offspring the same way, while under-groomed pups often couldn't. The care they received became the care they were able to give. It's animal research, not a direct map of human parenting, but the parallel is hard to ignore.

I watched a small version of this play out in my own house. When my cat had her two kittens, she barely left their side for weeks — grooming them, sleeping wrapped around them, tense any time I got too close. Once they opened their eyes and got mobile enough to need her a little less, she started doing something I hadn't expected: carrying them to me, one at a time, and settling them next to me on the bed before heading out for her own walk. I don't think that was an accident. I think she needed a break, and she trusted the nest — and me — enough to take one. Even animals know that caregivers need to be held too.

What We Lose When We Override the Instinct

A lot of parenting advice still pushes leaving a distressed baby alone — to build independence early, to avoid "bad habits." But that doesn't just work against your baby's biology. It works against yours.

Your body was built for this moment just as much as your baby's was. Holding, skin-to-skin contact, and responding to your baby's distress trigger a release of oxytocin in you — the same hormone that helped drive labor, and that deepens your own bond to your baby. When that response gets consistently interrupted or discouraged, parents don't just miss a bonding window. Some research links that disconnection to a higher risk of postpartum depression, since the very interactions that would normally help regulate a new parent's own stress and mood are the ones being withheld.

We were built for connection, not distance. And there's a piece of this that gets skipped constantly: self-soothing, the thing everyone is in such a hurry to teach, is an advanced skill. It isn't the starting point of development — it's the output of it. Children learn to regulate themselves only after they've spent enough time being co-regulated by someone else first. You can't rush a nervous system into independence any more than you can rush a bone to heal. Safety comes first. Independence grows out of it, on its own, when it's ready.

The Hardest Instinct to Trust: Closeness at Night

If there's one place this instinct gets tested hardest, it's nighttime. Sleeping close to your baby is one of the oldest parenting practices there is, and one of the most argued about.

The instinct makes sense biologically. For nearly all of human history, distance from a caregiver at night meant real danger. Newborns can't regulate their own body temperature yet, and sleeping close to a parent helps keep it stable. A parent's presence appears to help stimulate a baby's own breathing rhythm, and Dr. James McKenna, who spent decades researching mother-infant sleep at Notre Dame, found that babies sleeping close to their mothers show fewer pauses in breathing than babies sleeping alone. His research also found that breastfeeding mothers and babies sleeping close together fall into a kind of synchronized rhythm — stirring, adjusting, latching, settling — often without either one fully waking. He calls it "breastsleeping," and it's specifically built on a sober, breastfeeding parent sharing a firm, hazard-free surface with their baby — not simply any two bodies sharing any bed.

That distinction matters, because it's exactly where the public conversation tends to fall apart. Current guidance from the Canadian Paediatric Society and Health Canada recommends babies sleep in their own crib or bassinet in your room for the first six months, largely because population-level messaging struggles to cleanly separate "informed closeness done safely" from bed-sharing with real risk factors present — a parent who smokes or has used alcohol or sedating substances, a soft or cluttered surface, a very young or premature baby, sleeping on a couch instead of a bed. Even the official 2021 joint statement on infant sleep acknowledges that a large share of Canadian families bed-share anyway, by choice or by exhaustion, and focuses on helping them do it more safely rather than pretending it doesn't happen. That nuance rarely survives in the general "co-sleeping is dangerous" headline, which leaves a lot of parents feeling like their instinct to keep their baby close is something to hide rather than something to work through, safely and honestly.

I remember my own extended family nearly coming undone when I chose to sleep close to my babies. I heard every horror story about rolling over in the night, and it stressed me out more than I want to admit. But my gut told me this was right, and I've since read enough to know why. Psychoanalyst Erica Komisar has written about the benefits, for both mother and baby, of sleeping close enough to sense one another for up to six months to a year, and makes the case that nighttime security matters even more than daytime security — especially after a day apart. Pediatrician William Sears makes a related point that runs against almost everything new parents are told to want: frequent night waking isn't a problem to fix. People will ask you if your baby is "sleeping through the night" yet, as if that's the goal. Sears argues it isn't — that very deep, prolonged infant sleep isn't necessarily the safest kind, and that babies who sleep close to a parent tend to wake more easily, cry less at night, and show less nighttime anxiety overall. Both Sears and McKenna point to lower rates of SIDS in cultures where sleeping close to baby is simply the norm.

None of this is a suggestion to ignore safety guidance — please don't. It's an invitation to hold two things at once: the science genuinely supports the biological pull you feel toward your baby at night, and safety still depends on the specifics — a sober, smoke-free household, a firm surface, a baby who isn't premature or very young, nothing soft within reach. Get those pieces in place, and you're no longer fighting your instinct against the evidence. You're finally letting them agree.

Fifteen Years of Watching Kids Grow Up

I don't just believe this because of research. I've watched it play out for eighteen years — first as an activities facilitator inside a homeschool community as well as hosting summer camps with kids ages six to eighteen, and more recently hosting my own teens' friends for extended stays in our home. Across all of that time, watching hundreds of children move through childhood into adolescence, the pattern held: the most emotionally steady, securely grounded kids I've known were, overwhelmingly, the ones who slept close to their parents well past babyhood. Not the ones pushed toward independence early. The ones who were allowed to lean on their people for as long as they needed to, until they simply didn't need to anymore.

You Were Not Meant to Do This Alone

Here's the piece that so often gets left out of the co-regulation conversation: it doesn't stop applying once your baby arrives. You need it too.

Even in the middle of all those good, connecting hormones — the oxytocin, the bonding, the fierce love that shows up whether or not you feel ready for it — you are still a person who is brand new to this. And new parents don't just need information. They need to be nurtured themselves, the same way you're learning to nurture your baby: fed, listened to, given an extra pair of hands, reassured that what they're feeling is normal, and reminded, often, that reaching out isn't weakness.

That's the work I do. I bring food. I bring calm. I bring eighteen years of watching this exact season of life up close, so that when the noise gets loud and the advice gets contradictory, you have someone in your corner who can help you hear your own instincts again.

You were not meant to do this alone. Let's talk about how I can help.
