Co-Sleeping, Safety & the Nervous System: Rethinking “Independent Sleep”

Share

Worthy Parent, Worthy Child — by Ntombenhle Khathwane

I know now that babies, children, are wired for independence, for growth, they do not need to be taught it, they naturally thrive for it.  What interrupts their natural push for independence are the things we, as parents and caregivers, do with good intentions that challenge their primary need for safety.  When a child’s safety is challenged, they essentially go numb and freeze and can become stunted, and we won’t even know it!  When I became a mother, one of the main rules I read in many parenting books was, babies sleep away from you so they can “learn independence.” I tried that script. But my instinct kept whispering another story, that closeness at night is not spoiling, it’s soothing.

I co-slept with my 3 children until around five or six, when they naturally transitioned on their own and wanted to sleep in their own rooms.  I saw real benefits, easier preschool transitions, less separation anxiety, and calmer nights for all of us. And it brought their daddy and I closer, and built a closer relationship between him and his kids. Today, in a world where childhood anxiety and sleep struggles are deeper and rising, I want to gently challenge “conventional” parenting and invite us to remember what many ancient cultures have always known: feeling safe is the primary work of childhood, and night-time proximity can help wire that safety.

 

Growing up, my parent’s bedroom was a no-go zone, and I wanted to change that for my family. I want my kids to feel free in every room in their home. The key has been teaching them to be respectful and approach our adult spaces with care and respect, just as we do their spaces.  It is easier now that the youngest is 9 years old.  Kids, especially when they are younger, do not have the language to express the emotional discomfort, dysregulation, they feel, yet knowing they can come to mommy or daddy for a cuddle anywhere, anytime, helps to normalise seeking assistance to co-regulate and calm their very busy nervous systems.

 

What we mean by “co-sleeping?”

People use the word differently, so let’s be clear:

Room-sharing: baby/child sleeps in the same room as the caregiver (e.g., bassinet or cot near the bed).
Bed-sharing / family bed: child sleeps on the same sleep surface as a caregiver.
Sidecar set-up: a cot with one side removed, attached securely to the parents’ bed (separate surface, shared proximity).

Modern Western advice often discourages bed-sharing in infancy because of safety concerns, while many guidelines do recommend room-sharing for the early months. Across much of Africa and the global South, and historically in many societies, some form of close sleeping has been common, practical, and expected. Different homes, different norms.

 

Why closeness at night can help: the body science in simple words

Babies and young children regulate their bodies through us. Proximity (hearing a parent’s breathing, feeling warmth, soft touch, a known scent) supports:

Co-regulation: a child’s heart rate, breathing, and stress hormones settle in response to our calmer rhythms.
Oxytocin & bonding: contact boosts the “connection hormone,” which can lower stress and support sleep.
Attachment security: repeated experiences of “I’m not alone in the dark” build a baseline belief: I am safe.
Night feeds & soothing: for infants, especially breastfeeding dyads, closeness can make night care gentler and faster.

This doesn’t mean every family must bed-share. It means that proximity is a biological calming signal, and we can use it – in a way that fits our home – to support nervous-system safety.

 

“But modern parenting says…”

A strong cultural story says independence = sleeping alone early. Yet independence grows from secure dependence. When we meet a young child’s need for closeness, we’re not creating clinginess; we’re building the security from which they can separate with confidence later.

 

In many African homes, older generations created safety with closeness – mothers and children shared spaces; aunties and gogos co-regulated babies through the night; siblings slept together. Somewhere along the way, some of us started to believe our rooms must be “sacred” adult spaces, children must not enter, and a child’s night-time need equals poor discipline. I honour every home’s boundaries – rest matters! – but I also believe we can reclaim ancient gentleness: proximity as a sacred rite of early childhood.

 


Benefits you might notice (birth to the early primary years)

Easier separations: children who feel safe at night often manage daytime separations (preschool, sitters) with more steadiness.
Fewer night terrors / fears: the “monster under the bed” shrinks when a trusted adult is right there.
Smoother sleep cycles: many families find fewer prolonged wake-ups when soothing is immediate.
Stronger parent–child connection: the day’s busyness is softened by the night’s quiet reconnection.
Cultural continuity: for many of us, co-sleeping is how our mothers and grandmothers did it. Keeping that thread can feel grounding.

None of this is a guarantee, and plenty of children sleep beautifully in their own rooms. The point is not to prove one “right way,” but to legitimise proximity as a healthy, evidence-aligned option.

 

A middle path: protect parental rest and keep proximity

You can mix closeness with boundaries. Try:

Start-in-own-bed, join-later: child starts the night in their bed; if they wake after midnight, they’re welcome to a floor mattress in your room or to the sidecar cot.
Sidecar or floor bed: create a safe, firm sleep surface joined to your bed so everyone has space.
Rotating nights: parents alternate who is “on duty” for night soothing to protect sleep and work demands.
Connection before sleep: 10–15 minutes of undividedbedtime presence (story, gentle massage, prayers) can reduce the need for constant overnight contact.
Morning cuddle rule: if you prefer separate sleep, make morning cuddles a ritual to meet that skin-to-skin need.


Safety first — always

Co-sleeping with infants requires extra care. Do not bed-share if any of the following apply:

A caregiver has consumed alcohol, sedatives, or recreational drugs; or is a smoker.
Extreme exhaustion, untreated sleep disorders, or illness make arousals less reliable.
The baby is premature or low birth weight (higher risk group – choose room-sharing, not bed-sharing).
Soft surfaces (sofas, armchairs, waterbeds) or heavy duvets/pillows are involved.
Pets or older siblings are on the same sleep surface as a young infant.

General safety: firm mattress; no gaps where a child could roll; light bedding away from baby; baby on their back; long hair tied back; keep the sleep space cool; ensure everyone knows the plan.

 

If your child is past infancy (toddler to early primary), these risks reduce substantially, but still create a clear, uncluttered, firm sleep space.

When not to co-sleep (or when to pause)

High household stress or conflict: if nights are tense, prioritise calming the environment first.
Caregiver dysregulation: if you’re very anxious or struggling with mood, proximity may amplify yoursleeplessness. Room-share or do contact at bedtime, then create space.
If co-sleeping fuels resentment between partners, rethink the set-up (rotations, sidecar, floor bed for the child). Love thrives where everyone’s needs are named and respected.


Story time: one night in our house

 

There were seasons when preschool started early and my little one woke scanning the dark for me. A hand on her back, my slow breathing, and the whimper softened into deep sleep. Weeks later, drop-off tears shrank too. That’s the nervous system learning a new sentence: “I am safe, even when we separate.”The night’s message was teaching the day.

If co-sleeping isn’t for you

You can still feed the same nervous-system needs:

Room-share for the early months or use a sidecar for touch without bed-sharing.
Longer bedtime presence (singing, rubbing feet, storytelling) to saturate connection.
Comfort “bridge” items: your T-shirt as a pillowcase, a scented cloth, a recorded lullaby.
Predictable night script: the same gentle words each wake-up – “I’m here. Breathe with me.”

Closing thought: safety grows independence

Our children aren’t auditioning for independence at two. They’re building capacity for it. Whether you co-sleep for months or years, or keep sleep spaces separate and build a rich connection, let the guiding question be: “Does our night-time plan teach the body: I am safe?” Because a nervous system steeped in safety by night becomes a child who explores bravely by day.

 

There is no one right way, there is your way, shaped by love, culture, and context. Trust your instincts, honour safety, protect your rest, and let closeness be a tool, ancient and wise, for raising steady, secure little humans.
