Co-sleeping demystified: the pros and cons of bed-sharing

What is co-sleeping?

Co-sleeping is sleeping near enough that both parent and baby can easily touch, hear, smell and see each other. These recent years, a lot of scientists and mothers have lost some sleep over the confusion brought about by whether or not a parent should co-sleep.

Child-rearing, for most of human history has been a natural and intuitive process. But in the 21st century, we’re bombarded with information overload and parenting is shrouded in conflicting interest and misperceptions.

So let me peek under the sheets and clarify these misconceptions. As a mother myself, allow me to share with you what I think, what resonates, and what worked for me on this co-sleeping debate.

Co-Sleeping demystified

Putting an infant to sleep should be simple. Back then when our ancestors were still living in the cave there were no cribs, no feeding bottle, no (sudden infant death syndrome) SIDS.

Bed-sharing has been the way of life even up to now on some cultures. In this case, the west is totally at odds with the east and with elsewhere around the world in terms of a thing as simple and as vital as infant sleep. Why the mess? Does it even make sense?

Bed-sharing around the world

Most aborigines carry their infants closely, strapped on a piece of cloth kangaroo style. While in the US, small children have a nursery room; an infant electronic monitor and a cold crib on their own, children in Asia particularly in Japan are co-sleeping together with their parents, way into adolescence. Unsurprisingly, Japan has one of the lowest infant mortality rates in the world.

In Africa, you can hardly find a nursery room. Cribs are not that utilized since babies usually slept on the parents’ bed and are allowed to play around the house at daytime.

Even at Southern Europe, England, South and Central America co-sleeping is an unquestionable part of parents’ daily lives. It is a generally accepted fact, so what is this co-sleeping squabble of the Western scientific community all about?

The argument against co-sleeping

Bed-sharing with an infant interferes with husband-wife relations

Having a baby to hold and care for the whole night interferes with sex. Intimacy between couples must not be diminished by childbirth. Parents need space and quality time together and having a baby to look after the whole night defeats this.

It’s unsafe

Safety is the main argument of most doctors out there. It increases the incidence of SIDS or crib-related deaths as per research. In addition to cot death and suffocation, the baby can also fall over especially during his crawling stage.

  • Baby sleeps better, longer when left alone.

Some parents believed that the noise they generate when walking, snoring or closing the doors at night time can startle a sleeping baby. Thus, this is the reason behind the popularity of a separate nursery room in the West for babies as young as a newborn.

It promotes independence

A baby must learn to fall asleep on his own and the earlier that he learns to do it, the better. A child that is constantly held and cooed to sleep will have a harder time later on to sleep independently.

It will be difficult to convince a growing child to sleep in his own room alone once he is already accustomed to sleeping with his parents. He will have a hard time standing up on his own and will always seek the validation of an adult.

The argument for co-sleeping

Co-sleeping comforts, soothes and nurtures

Bed-sharing makes breastfeeding easier both for baby and mother. Feeding time is considerably longer for breastfed babies since mommy can fall back asleep once the baby is latched.

More than sustenance, a mom’s breasts are baby’s number one comforter. Likewise, child who has recently learned to speak can also use this time to share stories with his parents. This quiet time is valuable in terms of sharing and tender snuggles.

Baby feels safe

A baby cries less when mom is just nearby. The rhythmic sound of mom’s breathing and the familiar warmth calms a baby naturally. While sleeping side-by-side, the heart and breathing rates of mother and child fall into a pattern of synchronisation.

This way, the mother can immediately be alerted if baby’s breathing suddenly stops, even while asleep. By being able to immediately respond to every need without crying out, the baby is conditioned to trust their parent.

Co-sleeping + breastfeeding are the best for baby’s health

Even better, babies who are breastfed are more likely to gain weight faster and have fewer incidences of SIDS and childhood infections. Night time breastmilk contains more growth hormone and soothing melatonin to help the baby grow faster during sleep.

It was even said by some experts that these breastfed children will more likely grow into confident and emotionally stable adults, more so than their bottle-fed counterparts.

More sleep for mom

The main reason most mothers bed share is due to their need to breastfeed and sleep. Mothers who breastfed babies are more likely to practice co-sleeping than those who are into bottle feeding. A mother has lighter sleep all night once she is co-sleeping. Yet based on some expert evaluations, this type of sleep is even better as compared to mothers who have to get up at night to nurse a bottle-fed baby at the crib.

Co-sleeping + breastfeeding helps a mother recover faster

Mothers who breastfed slept better as compared to their non-breastfeeding counterpart. The letdown of breastmilk that releases oxytocin helps these women to feel motherly and relaxed, reducing the risks of postpartum depression.

Breastfeeding is tiring in itself but its positive health effects last long. These same mothers are also less likely to acquire breast, uterine and cervical cancer than women who have not given birth nor have not breastfed at all.

Safety Tips for Effective Co-sleeping

No alcohol and drugs

Taking alcohol before sleeping is a big no-no for parents who co-sleep. Alcoholic drinks alter adults’ sleeping patterns, making them less likely to respond to baby’s cries and movements. The same holds true for illicit drugs and even prescribed medications. A drug no matter how harmless can have an effect on the depth of sleep.

Do not ever sleep together at a sofa or a make-shift bed.

Sleeping together at a roomy bed is risky enough but sleeping side-by-side at a sofa is even more worrying. This is because a common sofa has some corners and cushions that can trap baby and smother him silently.

Tie up long hair and stay away from duvets and covers with exposed threads.

A baby’s fingers and small toes can easily get tangled on mom’s long tresses. What’s more, crocheted covers are usually made of threads that can easily get pulled, tying a baby’s small fingers around them.

Take note also not to wear any jewelry to bed as baby can pick them up and put them in his mouth and hands can also get caught inside these trinkets.

Do not co-sleep an infant with their toddler siblings or with a babysitter.

A baby younger than 18 months must not share the same bed with their older siblings. Older kids and toddlers are usually active sleepers, they tend to toss and make complete turns throughout the night. Their weight might not be much, but it is still enough to suffocate the baby.

In addition to younger kids, be wary also of babysitters who tend to fall asleep with baby on the same bed. They are also not as sensitive as a mother in terms of anticipating and responding to an infant’s cries.

Try a co-sleeper crib to make the bed sharing transition easier.

Co-sleeper cribs that are adjustable to the height of a regular bed are your best bet if you are unsure whether the baby will be safe sleeping on a regular bed. This is especially true for obese parents, adults with apnea/sleep disorders or for parents with physical limitations. Co-sleeper and additional guard rails are also applicable for babies that are physically frail or are born prematurely.


Much has been said about the perils of co-sleeping. Yet study after study finds that solitary “independent” sleepers to be more likely to get attached to security objects to substantiate for a parent’s warmth.

Humans by instinct crave for touch and for connection. The feeling of interdependence started in the womb, and it must not stop at birth. There is a reason why co-sleeping is practiced by most native civilizations since time immemorial.

Babies are social creatures; they cannot grow and thrive without an adult’s constant tending and guidance. Rather than letting baby self-soothe itself to sleep at the darkness and cold of the night, why not envelop him on a parent’s comfort and love?

As for me, nothing beats the tender snuggles of my little ones during those cold twilights. That is the way I am raising my children and not surprisingly, they thrived. So why change?

  1. I absolutely love this. Well written. I am a new mother with 6 month old baby. I co-sleep with him the whole time since he came home. I didn’t tell anyone really but did it silently because of reading all of the Sids stuff and those who look down on it. Since I am “mother” and I knew myself and how I sleep I felt comfortable doing it and never questioned myself because of I’m sensitive to a lot of things-people around me included. There seems to be hype against co sleeping but it just came natural to me 🙂 Nice to hear positives for a change

  2. Many factors can contribute to what’s best for a particular mom and baby. I’m in the opposite camp and both of my children slept in their own crib from birth. They are grown, now 22 and 25. I found having them in my bed disrupted my sleep and that didn’t help anyone. They both slept through at very early ages….yes, I did the cry yourself to sleep tactic and I never woke a sleeping baby….neither had colic or other health problems so it was easier to give that a go. I only breastfed for 4 months then 3 months because both times I didn’t have a lot of milk and I also didn’t have a desire to continue breastfeeding; equality for me included Daddy feeding the baby. I was made to feel guilty but chose to ignore the criticisms. It was the right choice. Continuing to breastfeed would have been a stressful choice for me. Both of my children slept through very early on while still on breast. My son slept 8 hrs by 3 months and my daughter 12 hours by 8 weeks…yes, you read that right…..she never slept in the daytime though. She had very few naps for a newborn but she would feed constantly for about 2 hours before crashing for the night. We are a very close and demonstrative family but that didn’t extend to sleeping quarters or eating (I always cuddled while bottle feeding but both were onto cups by 8-9 months of age). I have two very well-adjusted, successful adult children who felt supported and loved always and that’s all that really matters.
