Bedsharing remains one of the more controversial decisions a parent can make these days, with articles touting that doing so will result in you killing your child, sharing horror stories of families who woke up to a dead baby, all while leaving out any information about risk factors or other environmental considerations. The American Academy of Pediatrics
The question that many people ask is: How can two different sets of professionals read the research and end up with totally opposite conclusions? Why does the governing body in the USA feel so differently from that in the UK (or elsewhere, like Japan, where bedsharing is incredibly common)?
For years, everyone thought bedsharing was dangerous based on a slew of epidemiological studies looking at risk factors for infant deaths – specifically SIDS or suffocation. In those studies, bedsharing was one of the main risk factors of death and so it seemed prudent for most governing agencies to take an official stance against it. However, things got muddier as time went on and research progressed. Newer studies weren’t so clear-cut, with other factors – like smoking or drinking – interacting with bedsharing to increase the risk of harm to an infant. And like a pendulum that swings back and forth, when one study emerges that seems to clear bedsharing, another hits the press that seems to vilify it.
In recent years, two large studies seem to be oft-quoted in support of this anti-bedsharing stance: The first is a meta-analysis by Carpenter and colleagues[3] and the second is a study that found a higher risk of SIDS/suffocation associated with bedsharing in younger infants (0-3 months) than older infants[4]. Other studies that have come out at similar times (e.g., [5]) but come to opposite conclusions, do not receive nearly the same press. It’s as if our society has made up their mind and the media is playing part to a confirmation bias about the dangers of bedsharing.
Does the research really support an anti-bedsharing message? What should parents really be taking home? My hope here is that by looking at the research that is being used to form opinions on bedsharing, I can show you what is involved in the research and allow you to come to your own conclusion about the real risks inherent in bedsharing versus the risks of other factors interacting with bedsharing.
Given the focus on the larger meta-analysis conducted by Carpenter and colleagues recently, I have decided that the main studies that were included in this analysis should be the primary focus of this discussion as they are what seems to be informing people’s opinions. I also include some newer studies that also seem to suggest bedsharing is problematic as well as those that seem to not find the same level of risk demonstrated in the aforementioned studies.
The Risk of Bedsharing Per Se vs. Other Factors
Source: ISIS Co-Sleeping Image Archive
When the first bits of epidemiological research emerged, bedsharing was found to be a large factor in contributing to infant death, something that was mirrored by Carpenter and colleagues in 2013 (as these were the studies that were included in this meta-analysis). These studies seemed to find a 2-3 times increased risk of death associated with bedsharing[6][7][8][9]. Although the recent meta-analysis boasts that it is a meta-analysis, giving us the best possible answer to the question of risk in bedsharing, the data we obtain from any meta-analysis is only as good as the data that goes into it. In this case, many variables were omitted or missing data from so many cases that the meta-analysis should be interpreted with extreme caution.
Looking at the individual five, epidemiological studies included, we see the following missing factors:
- The New Zealand study [6] failed to account for alcohol use, type of bedding and tog value, and sleep surface (e.g., bed versus sofa). However, as this was one of the first studies done on the topic, it is difficult to fault the researchers for failing to assess these variables. The later studies should fall under greater scrutiny given that they had prior knowledge of factors that interacted with bedsharing to increase the risk.
- The European case control study [7] did include many of the confounding factors, including alcohol use and duvet use, but not all centres reported on these variables, thus the data is incomplete. Notably, only 78% of the places reported on alcohol use and 56% reported on duvet use; the rest was predicted using regression, a method that has since been found to be flawed as it tends to overestimate significance. In this case, this would mean that alcohol use and duvet use were overpredicted and depending on whether more missing data was present in the control versus risk groups, this could sway the results either way.
- The Scottish study [8] omitted so many variables it’s difficult to know how to interpret the findings. The study failed to account for alcohol use, duvet use, breastfeeding (though they had data on breastfeeding), smoking during pregnancy, and illegal drug use.
- The Irish study [9] actually collected the most data and included a lot of important variables such as tog value of clothing plus bedding, baby prone to sweating, smoking, drinking, and more. They also assessed whether bedsharing was the usual routine or not, though did not include this in the adjusted odds ratio for bedsharing despite finding that for 50% of the SIDS cases that were found bedsharing, this was not the usual sleep pattern. Three large interactions with bedsharing were found in this study: Maternal smoking, birth weight adjusted for gestation, and tog value. Indeed, in this study, when looking only at non-smokers, ignoring the other two interactions with birth weight and tog value, bedsharing was not statistically significant as a risk factor.
- The German study[10] poses a slight problem for someone like me because the key variable missing in this report is bedsharing. Yes, according to the citation Carpenter and colleagues provided, there is no information on bedsharing at all. This does not mean that this data was not collected and provided to Carpenter, but that we have no way of knowing what the risk was or how it interacted with other variables. As such, I can make no comment about the risk of bedsharing in this particular study or what variables were included or omitted.
Thus, by the time the meta-analysis was performed, over 60% of cases were missing information on alcohol use and illegal drug use, whereas no data on type of bedding or tog value (e.g., the use of a duvet) and prenatal smoking were included in the analyses, despite these being large risk factors identified in the original research. For example, smoking prenatally was associated with a 4.09x increased risk of death in [6], duvet use was found to be associated with a 2.95x increased risk of death in [7], and tog value > 9 in [9] was found to increase the risk of death by 9.68x, all larger than the risk of bedsharing.
Defining Variables, or ‘The Variable Problem’
The variable problem is one that is rampant in a lot of research, especially parenting research. I have discussed it with respect to various parenting methods researched today, such as breastfeeding and sleep training, and it sadly also plays a role in the bedsharing research. The variable problem refers to the fact that many variables, as they are used in research, are poorly defined and this influences the types of conclusions we can make from any research. In the bedsharing debate, there is little concern over the definition of bedsharing (though there is concern about reporting which I will touch on below), but how some of the confounding factors are defined and measured can greatly influence how much of a role they are deemed to play.
On top of the issue of missing variables, here are some of the ways in which the major case control studies may be subject to the variable problem:
- One of the glaring examples from the New Zealand study[6] was the way in which breastfeeding was coded. Namely, instead of looking at a dose response or even current breastfeeding, the researchers included breastfeed as positive if the mother engaged in “any” breastfeeding. This fails to capture the information needed to properly assess the real risk, especially as we know that not breastfeeding does increase the risk of SIDS significantly.
- The European case control study[7] also suffered from the variable problem. In this case, alcohol was measured as the number of drinks the mother had consumed in the previous 24 hours using groupings of none, 1-2, and 3 or more, ignoring the possible real effect of timing on alcohol use. To clarify, a mother who has a glass of wine at lunch is now lumped in with the mother who has two shots before bed. This is likely why the authors found that 1-2 drinks was not associated with any increased risk compared to no drinking at all. Timing is, after all, everything.
- In the Scottish study[8], the key smoking variable was defined as “either parent smoked” meaning that the lower risk for a partner smoking was now confounded with that of the mother smoking. This means that women who were not smokers were now included as having this risk when they didn’t. This has the potential for lowering the odds ratio for the smoking by bedsharing interaction as a risk factor. In addition, breastfeeding (though not included statistically in the model and only examined on its own) was recorded as “any breastfeeding”, again missing out on the dose response and the interaction with bedsharing.
- The Irish study[9] continued with the problems in defining breastfeeding, which was simply defined as “breastfeeding initiated at birth” or not. Again, as with European case control study, parental alcohol consumption was measured over a 24-hour period which may explain why the variable was non-significant.
- The German study[10], as reported, did not include bedsharing and it also did not provide information on other variables of interest for this examination. Instead the focus was on medical conditions that may have explained the infant’s death and although this is highly relevant for the discussion, it does not speak to the control of other risk factors that interact with bedsharing, such as alcohol consumption by parent or breastfeeding.
In addition to the problems with the variables themselves, there is the issue of reporting. The concern here is how accurate the reporting of bedsharing is in the control group. Why would we think there is a problem? Well, anecdotally many parents admit to underreporting bedsharing when they are faced with questions by health professionals, especially when the presiding view is that it is “wrong” or “bad”. The rates of bedsharing in the control cases or when asked by a doctor do not mirror studies which ask in a more benign or anonymous manner. To highlight the discrepancies, research presented at the Pediatric Academy Societies meeting in 2014 reported 20% of parents “regularly” bedshare, using a large sample of women recruited from hospitals. However, another study found that 72% of parents of 3-month-olds reported “regularly or occasionally” bedsharing with their infant[11].
Now, a couple differences in these studies: 1) The first was conducted in the USA whereas the second was in Canada; and 2) the first looked only at “regular” bedsharing whereas the second included “occasional” bedsharing as well. This second point brings up another issue: The frequency of bedsharing. For the sake of this discussion, frequency is an important factor as many of the dangers may come from “occasional” bedsharing, especially if it occurs unplanned and due to immediate circumstances. Returning to the Irish study that was included in the Carpenter analysis[9], the degree of regularity of bedsharing was found to be irregular in the majority of deaths where bedsharing was a factor.
Additionally, in most studies the control group reports only on the previous night. However, if a vast majority of families only “occasionally” bedshare, the previous night may be missing important information on risk. Another factor is that many families only bedshare part of the night and yet report that they do not bedshare, often because they didn’t start the night there or end the night together. This hides the fact that bedsharing is taking place and thus artificially raises the risk in the research. Additionally, if people are not regularly bedsharing in the case group, then the chances that they are doing so safely and without other risk factors is dramatically decreased.
Is Age Everything?
Source: ISIS Co-Sleeping Image Archive
One of the key findings that is consistent across any study that finds a risk of bedsharing is that it is age-dependent. It is pretty conclusive now that bedsharing after 3-4 months of age is not associated with any increased risk, no matter how the research is done, but the debate around younger children remains. In line with this, the other recent study that made headlines was an analysis of risk factors for infant death by age[4]. This study was interesting in that it found more younger infants died in bed with a parent than older infants did, but omitted a key variable: the base rate of bedsharing.
Why is the base rate important? Imagine if you had two groups of students and you wanted to know how they differed on how many students didn’t do their homework, measuring it as a yes/no of whether or not they turned in homework each day. Would this be a valid measure? Hopefully you can see it’s not because what we’re missing is the base rate of who has homework each day. That is, if one group is more likely to have homework, they are also more likely to do it and turn it in, resulting in an erroneous comparison between the two groups.
A similar thing occurred in this study in which the actual base rates for bedsharing between the two groups were not examined. That is, one needs to look at the proportion of infants who bedshare at the various ages and make comparisons to those rates, not comparisons across ages. Thus, although younger infants were more likely to be found bedsharing, it is entirely plausible that parents are more likely to bedshare with younger infants more generally. If this is the case, then bedsharing is not a risk, but the sleeping location simply reflects where infants normally sleep. In fact, another, more recent study examined this very issue in younger infants while controlling for the known risk factors and found no significant increased risk even in younger infants[5].
Is One Death Too Many?
The final argument that is often made is that “one death is too many” in terms of bedsharing. The assumption here is that all bedsharing deaths would be prevented if babies slept in cribs and no crib deaths would be prevented by bedsharing. When bedsharing is done unsafely, then yes, it would likely (though not always) be prevented by using a cot safely; however, this speaks to education on how to safely bedshare instead of condemning the entire practice. It is unlikely that, absent known risk factors, an infant bedsharing would be safer in a crib, and this is exactly what more comprehensive research has found: No increased risk, but this does not mean no risk.
This issue also speaks to the etiology of SIDS which is looking more to be biological in nature (though it may interact with environmental factors). If the etiology of SIDS is linked to neurological disfunction, then sleeping location may not matter much at all. In fact, we may have reverse causality at play. That is, if a child has a predisposition to SIDS, it may manifest in ways that affect sleep (e.g., sleep apnea, fussiness/crying) and this may lead parents of these children to bring their babies to bed with them in order to either watch over them or try to get some sleep themselves. In this case, the bedsharing could be the result of the problem that leads to SIDS.
As we don’t know the actual etiology of SIDS, but we know that suffocation can be a risk factor and that bedsharing rates are high and rising, this begs the question: Why are we not teaching parents safe bedsharing? Would these deaths be avoided if we were able to help families prepare their environments in a safe manner and recognize their own risk factors when it comes to bedsharing?
Conclusions
I used these recent studies to highlight the problems with bedsharing in the literature and to explain why some groups are moving away from a strict interpretation of the research as suggesting “no bedsharing”. There are other studies out there that suggest bedsharing is dangerous, but I have yet to come across one that did not suffer from the main problems highlighted herein, namely either omitting key variables or having ill-defined variables that limit interpretability.
For example, recent research in the American Journal of Public Health[12] which condemned bedsharing due to the finding that a majority of SUIDs were found in an adult bed, yet the authors did not include any assessment of breastfeeding, tog value, alcohol consumption, smoking, and so on. As the focus of this examination was strictly the sleep environment, this made sense for their purposes, but fails to consider the facts we know interact with bedsharing, making the recommendations against bedsharing outrageously premature. [Of note, a higher proportion of SIDS cases (SUID encompassed SIDS, suffocation, and undetermined cases) were still found in a crib (37.7%), not an adult bed (33.5%), but again we have no baseline values to compare to making any conclusions impossible.]
You may read this and feel that bedsharing is still something that is inherently dangerous, though I hope that after reading this you are able to see how the limitations in our research really do influence how we’ve taken data that is problematic and used it to make recommendations that fail to capture biological needs, human nature, and human history. The question has to become, how will we best benefit families? Is a blanket ban the way to go or would more education and information (while opening up lines of communication with health care providers) be more effective?

As tog is not defined here: the tog value of bedding is (generalizing here) how much heat gets trapped. e.g. a high tog value equals bedding that keeps you warmer. It’s a unit that is displayed on bedding the UK but not really used in the US.
Ikea’s warmth levels (cooler, warmer, extra warm) are very similar and are probably based on these tog values.
Thank you – it’s true that not all people will be aware of what a tog value is!!
BC Coroner Services in its 2009 report explicitly warned against the mythical *safe*bedsharing, even going as far as to directly expose the fact that no one in real life bedshares like dr McKenna prescribes despite everyone using him as their go-to reference – exactly like this author did. BC Perinatal Services ignored the recommendations from that report, as well as Public Health Agency of Canada recommendations against bedsharing, and in 2011 developed their own bedsharing-friendly guidelines that were a perfect example of the harm reduction message the author insists on. As part of prenatal care mothers received brochures and infant sleep advice that endorsed position how there is no evidence that bedsharing in the absence of major additional risks ( smoking, alcohol and drug use) is dangerous. Like this author, they chose to stick their fingers in their ears and ignore all that “touting” of dead babies by the coroners who investigate these deaths in greatest detail (before they “tout” them around). The epilogue is yet another example why the harm of bedsharing and all other unsafe infant sleep practices should never be minimized: http://www.perinatalservicesbc.ca/Documents/Resources/Alerts/BCCSInfantSafeSleepAlert.pdf
” Unsafe Infant Sleep Practices
There has been an increase in infant deaths related to unsafe sleep practices. The BC Coroners Service Child Death Review Unit has identified an increase in infant deaths related to unsafe sleep practices.Over the past three years, there has been an average of 18 sleep related deaths per year. In 2016, in just under four months (between January 1 and April 28, 2016), 15 infants have died. Almost all were younger than six months of age. Coroner investigations identified that many of these infants died due to:
– suffocation when placed prone on soft blankets or mattresses,
– an overlay by a parent (sleeping together on a bed or couch), or
– suffocation due to head covering by a blanket.
Health care professionals are reminded to ensure that safe sleep practices are discussed with all expectant parents and parents/caregivers with young infants.”
One cannot help but wonder to what extent intellectually dishonest blogs like this one published in January 2016 contributed to creating the need for such a heartbreaking alert already in May 2016. Maybe the author will manage to find the ethics and the morals that they’ve displaced somewhere under this heap of bedsharing bias and at least shut this piece down. Or, they will continue with their faulty argumentation and keep on claiming how “It is unlikely that, absent known risk factors, an infant bedsharing would be safer in a crib, ” Adult bed = unsafe sleep surface. An infant, any infant, is always safer in a crib, sleeping on a surface that has been designed, tested and approved as safe for all infants to sleep on.
First, let us address the fact that even though BC has “safe bedsharing guidelines”, they are not promoted in practice. Having birthed both my children in BC I can say that no one ever addressed safe bedsharing with us. EVER. Thus it’s disingenuous to claim that people are being adequately trained in safe bedsharing.
Second, even if we accept the assertion that there is safe bedsharing information being appropriately given to families, your suggestion that it is directly the cause of the spike in deaths this year still doesn’t make sense logically. You would have to explain why over 5 years (2011-2015), there were no such rises with the same breastfeeding-friendly guidelines in place and what happened this year alone to make it suddenly different and only relevant to bedsharing. You would also have to address the fact that the reasons given for the rise in sleep-related deaths only lists bedsharing along with couch sharing instead of providing a breakdown of the causes of deaths in each category. Couch-sharing is not safe nor is prone sleeping or using blankets in a crib or elsewhere. These are not bedsharing specific issues. Instead I ask that you look at the research on SIDS and infant sleep to see why there may be other factors that are at play here, such as the high rate of viral illnesses that plagued BC this winter. Upper respiratory tract infections are one of the major risk factors for SIDS and were at a large increase this year.
Now, as to the claim that “adult bed = unsafe sleep surface”, you seem to not understand that many countries engage in bedsharing with lower sleep-related death statistics than our own. It is not inherently unsafe, but the way many of our beds are can be unsafe and that is why talking about safety and individual circumstances of each family is a must. Coroners only see death which is why we have research and statistics that must be used when talking about policy. And research doesn’t support what the coroners are trying to push in terms of a blanket statement against bedsharing. There’s nothing unethical or immoral about discussing research and putting out there what we know with respect to bedsharing, even if it doesn’t agree with your own bias.
“Now, as to the claim that “adult bed = unsafe sleep surface”, you seem to not understand that many countries engage in bedsharing with lower sleep-related death statistics than our own. It is not inherently unsafe,”
Yes it is. Western adult bed mattress is not a sleep surface designed, tested or approved as safe for infants to sleep on. In those countries you are pointing towards like Japan I assume, only 6% of infant cosleeping (bedsharing) according to their own sleep environment studies occurs while sharing Western adult bed mattress. Bedsharing in Japan is done by sharing floor and on it a hard, firm, mat, or the baby sleeping on a separate mat, or in a designated child bed ( crib). https://www.ispid.org/fileadmin/user_upload/textfiles/SIDSI2006finalabstractbook.pdf
Data on countries in developing world and sleep-related deaths is scarce to non-existent, but I can’t think of a better reason to stop using them as argument in favour of supposed privileged industrial world bedsharing safety than the reality of rates and under-reporting that we can extrapolate from existing sources like this one ( as long as we are intellectually honest that is) : http://paediatricaindonesiana.org/pdffile/41-9-10-8.pdf
Not to mention that dr McKenna claims how socioeconomic status and lack of being bedsharing enlightened are pretty much the only things that make bedsharing inherently dangerous, so most of the people in those “many countries” you are citing are not bedsharing safely at all according to the *safe* bedsharing expert referenced in this post. Perhaps *safe* bedsharing advocates could start mentioning that fact instead of going for a cultural appropriation bandwagon fallacy at the expense of people in the developing world – If they want to avoid their scholarly discussions of bedsharing risks to be more moral and ethical than the one available on this blog, whose author clearly has no problem with utilizing such insulting bigotry for perpetuating their own biased agenda.
Addressing the the BC Coroner Service alert reply:
First – I see we are resorting to anecdotes as evidence now. If you want anecdotes, I shall gladly copy/paste dozens of accounts of moms from BC who got those brochures and read them and understood that bedsharing is perfectly safe, an understanding that was often enforced by their HCPs and advice how to *safe* bedshare.
Second – “why there may be other factors that are at play here, such as the high rate of viral illnesses that plagued BC this winter”. That BC Coroner Services alert is as clear as it gets that these deaths were due to unsafe sleep practices. I’m sure that the coroners and medical experts in question ” did their own research on SIDS and infant sleep to see why there may be other factors that are at play here” when they ruled out viral illness as cause of death before they wrote that the death was caused by an overlay by a parent on a death certificate.
We’re not using anecdotes, but rather pointing out that it’s not widespread. In fact, I know NO mother that got that information (which is very sad as I know quite a few moms in the Vancouver area). What that anecdote points out is that the idea of teaching safe bedsharing STILL isn’t happening. In fact, turning to your point in the next comment about Japan and unsafe sleep surfaces, if the TYPE of mattress isn’t discussed, then the discussion isn’t full. The type of mattress is a huge part of what constitutes safe bedsharing. Second, a brochure should NOT be the definition of “teaching safe bedsharing”. Would we consider that adequate for sexual health? No. It’s about open discussions with caregivers who can look at the specific situations of the families involved to determine what is and is not safe *for them*.
Second, what you are missing is that “unsafe sleep practices” are more or less safe depending on other factors. Viral illness isn’t the *cause* of death, but is implicated in SIDS research as a major risk factor. If you research SIDS, you will see that there is a 3-part risk model and that is what I refer to. As for determining overlay, that depends on the coroner and location as many now list “positional asphyxiation” when they know bedsharing occurred *even though they have no evidence for any asphyxiation*. There is the assumption that it must have happened as opposed to SIDS.
Now, to your next points (other comment). In Japan, as mentioned, it is a different surface (also not fully “tested” for babies btw, just known to work) and this is part of the safe bedsharing discussion. Again, if that’s not happening, that’s not appropriate.
As for developing world countries – I don’t know why you’re bringing that up or any element of cultural appropriation. This is about *human history*. Bedsharing has occurred in all cultures over history and only recently changed here. Why SIDS used to be known as “cot death”. Currently, in OUR culture, SES plays a role, but that has nothing to do with cross-cultural SES. Hopefully you can understand the important distinction there, but I’d be happy to explain further if needed.
I don’t know what to make of your link as the article you provided is on pneumonia, not bedsharing. However, it highlights the role of ARI in infant death at night. Back to one of the risk factors for SIDS.
” don’t know what to make of your link as the article you provided is on pneumonia, not bedsharing”
Never said it was on bedsharing, but on … the reality of rates and under-reporting of sleep-related infant deaths in developing world countries where bedsharing is the norm. And it’s quite an eye-opener in that regard.
“In Japan, as mentioned, it is a different surface (also not fully “tested” for babies btw, just known to work) and this is part of the safe bedsharing discussion.” This “different surface” is by default in Japan not a Western adult bed mattress. If you are suggesting that your Western adult bed mattress is as hard, firm and flat as a mat on the floor in Japan, or that bedsharing in a Western adult bed is as safe as an adult in Japan sleeping on a mat on the floor next to a baby in a crib – I got nothin’.
“As for determining overlay, that depends on the coroner and location as many now list “positional asphyxiation” when they know bedsharing occurred *even though they have no evidence for any asphyxiation*. There is the assumption that it must have happened as opposed to SIDS.” This is blatantly false because death with no clear evidence is classified as undetermined, not accidental. BC Coroner Services seem to be extremely well equipped in not just determining causes of sleep-related infant deaths, but also in carrying out subsequent higher level reviews too that account for any inconsistencies in the individual coroner findings.
“We’re not using anecdotes, but rather pointing out that it’s not widespread. In fact, I know NO mother….” Plural of anecdotes is not evidence – it’s anecdata. The fact is that current BC Perinatal Services materials promote bedsharing as safe in the absence of additional risk factors.
“The type of mattress is a huge part of what constitutes safe bedsharing.” And we can determine that an adult bed mattress is a safe sleep surface for infants by doing what exactly? One prominent bedsharing advocate wrote how her adult bed mattress was “firm and new” and that was enough. If such ” it looks safe enough from where I’m standing” standard is not something that parents are applying when picking infant car seats, why is picking a sleep surface, the basic and primary safety issue and contributing factor in so many sleep-related infant deaths, suddenly something that is negotiable and not so important at all? Sleep-related deaths due to unsafe sleep environment ( unsafe sleep surface, unsafe bedding, unsafe sleep position, bedsharing) annually cause more completely preventable infant loss than all other top ten causes of infant injury deaths combined. From where I’m standing it is an utmost hypocrisy to suggest that we need to just talk about it and employ and use less objective standards such as “in my opinion this adult bed mattress of mine is a safe sleep surface for infants” instead of regulated industry product specifications.
I’m still not sure why you brought up reporting in developing nations as is. No one has made comparisons to them. Speaking of human history does not mean you need to look at countries that are not similar in terms of SES and health-related issues to make comparisons.
I’m not suggesting it inherently is, though not all Japanese sleep on a mat on the floor. You can go to a mattress store and buy a mattress for bedsharing there too. Obviously the best would be having ALL mattresses tested and standardized for who can sleep on it. But that’s an issue of fighting regulators rather than parents. You want to stop the practice instead of focusing how to make the practice even safer which is asinine to me because sleeping close to a baby is a much-needed technique for many parents, especially in our culture where daytime productivity is also expected. And of course there’s the issue that adult mattresses are not tested which does not mean they are inherently unsafe. That hard adult mattress (put on the floor) may be equally as safe as the mats or mattresses used in Japan.
As I said, I don’t know about BC specifically; however, it’s not blatantly false and you can read about these cases and the decisions and the use of “positional asphyxiation” in the US.
What I was pointing out, using anecdotes, is that it’s hard to say that whatever BCPS has created is being used to “promote” bedsharing when many mothers have never heard of it. Or had experiences in hospitals and with their own doctors to the opposite effect. The materials may exist, but if you’re trying to say their existence is leading to deaths, you have to show they are actually being used and people are learning and following them and they are leading to death. None of which you have demonstrated.
First, I actually agree that I would love to see adult mattresses standardized and regulated for use with infants. It would be ideal. And I think that’s a goal worth fighting for!
Second, part of the problem that we’ve had for years with sleep-related deaths is that there’s your side which seems to view sleep and sleep practices in a vacuum which clearly doesn’t work. If putting your baby in a crib next to you worked for all families they would do it. If it worked for all babies they would do it. But it doesn’t. There is an ideal based on behaviours that don’t exist for a large portion of families and then there’s what mothers and families do to make things work. This is why we need discussion on bedsharing and safe bedsharing and teaching families the why of each safe rule so they can best apply it. But you can’t *eliminate* risk entirely. You have to weigh it and sometimes the risk of sleep deprivation that comes from not bedsharing is greater than the risk of safely bedsharing. (And if you are following guidelines, the data from Alaska which examined all bedsharing deaths suggests the risk is not great.)
“the problem that we’ve had for years with sleep-related deaths is that there’s your side which seems to view sleep and sleep practices in a vacuum”
As opposed to bedsharing advocates and their perfect bedsharing vacuum in which every minute of every time you bedshare is inherently safe. You (and your partner) were both perfectly rested every time you bedshared and could account for any parental fatigue as additional risk? No blanket or pillow or other unsafe bedding ever moved during the night? The adult bed was inspected meticulously for each sleep whether it had moved out of place and created entrapment and wedging hazards? Each and every time you breastfed, you were perfectly awake and made sure that the infant was placed on their back before you fell asleep?
(That never happened that perfectly of course, and it never happens even remotely that ideally in real life: https://www.facebook.com/themilkmeg/posts/1012752022111982 , which is why *safe* bedsharing deaths keep popping up as those with multiple unsafe sleep environment risks when properly investigated.)
“That hard adult mattress (put on the floor) may be equally as safe as the mats or mattresses used in Japan.” That “hard adult mattress (put on the floor)” that “may be equally as safe as the mats or mattresses used in Japan” also never happens IRL judging by the images posted on the link I provided. But let’s keep pretending that such *safe* bedsharing unicorns exists, because under most ideal conditions they might be just as safe as cosleeping in Japan!
