Does
Cosleeping Lead to SIDS?
What the AAP Doesn’t Tell You
By Linda Folden Palmer, DC
Does cosleeping really lead to Sudden Infant Death Syndrome
(SIDS)? Are pacifiers really a smart way of preventing
SIDS? The American
Academy of Pediatrics (AAP) would like you to think so, releasing
this fall what other medical experts have called “an ill-advised
and ill-informed statement” that simply flies in the face of
reason. Recommendations that advise against parent-infant bed-sharing
and support the generic use of pacifiers imply a “truly astounding
triumph of ethnocentric assumptions over common sense and medical
research,” according to Nancy Wight, M.D., president of the
Academy of Breastfeeding Medicine.
Yet if we review the very same research the AAP used to come
to its conclusions, the message is clear: The relative risk of
death
to
infants who sleep in a safe adult bed with a safe parent is not
greater than those who sleep next to their parents’ beds — and
their risk of death is far smaller than that of infants who sleep
in a crib in another room. In fact, for infants over 2 to 3 months
of age, the studies show that letting infants sleep in the same
bed as their parents in fact protects them from SIDS more effectively
than placing them near their bed.
Infants are at risk of suffocation in adult beds, just as they
are in cribs. The clear message should be that adult beds need
to be
made safe, without overly fluffy or heavy bedding, wedging dangers,
overheating, siblings (with a very young infant), parents who
have consumed drugs or alcohol or parents who smoke. Sofa sleeping
is
not safe with babies.
Yet the message we get from the AAP is that cosleeping is unsafe — period.
While breastfeeding is shown to reduce SIDS, the AAP does not even
mention breastfeeding. Instead, the AAP promotes the use of pacifiers — an
intervention that can impede breastfeeding and that the AAP recommends
without appropriate substantiation.
Safe cosleeping = healthy cosleeping
Unfortunately, none of the studies cited by the AAP report bother
to derive from their statistics a risk ratio for deaths of babies
co-sleeping in a family bed with safe, non-smoking, sober parents
who take reasonable efforts to reduce wedging and other suffocation
dangers. From the available statistics, full numbers can only
be guessed at — but cosleeping in safe conditions is clearly as
safe or safer than sleeping in cribs in the same room as parents
and far safer than sleeping in cribs in another room. Contradictory
to the AAP’s statements, it is clear that limiting safe cosleeping
will not reduce SIDS.
How could the facts from these research reports become so confused?
It’s important to understand what’s actually meant
by the terms used in the research.
The term "adult bed" usually includes dangerous sofas,
sofa chairs, make-shift beds and waterbeds, which account for a
large portion of the adult-surface deaths. Also, the term doesn't
necessarily
mean cosleeping is occurring, only that an infant is sleeping on
that particular surface. An infant sleeping alone on an adult bed
is at greater risk than when sleeping there with a parent. Failing
to understand these points makes appropriate adult bed-sharing
mistakenly sound dangerous.
" Bed-sharing/cosleeping" statistics and comments usually lump
together cases of infants sleeping with any adult in any state,
including over-exhausted, intoxicated adults, smoking adults, other children
and even combinations of these. These comments and statistics
also generally include dangerous practices such as sofa-sharing. Another
limiting factor of these definitions is that they usually include
statistics on infants who coslept at any point during the night
of their SIDS-related death — not necessarily at the time of
death. Conscientious parents are scared away from safe cosleeping
by such
slanted reporting.
SIDS or suffocation?
Notice that most studies define all unexpected infant deaths
as SIDS, while a few pose suspected suffocations as distinct
from SIDS. The
resulting statistics are quite different. While cosleeping may
reduce actual SIDS, suffocation risks are greater for bed-sharing
(as great
as they used to be for crib-sleeping, before safety standards
were taught), when appropriate precautions are not taken.
A few studies look for a new risk association with infant death
in bed-sharing: the finding that possibly half of those dying
while bed-sharing were not accustomed to bed-sharing — meaning,
among other possibilities, that the parents or adults were not
experienced
in protecting the baby from hazards, that the bed-sharing was impromptu
due to overtired or intoxicated parents, or that the baby may have
been experiencing extra fussiness for some health reason and was
brought to the parental bed for that reason.
What’s behind the figures?
Why do no studies fully compare safe, conscientious cosleeping
with other sleep situations? The results would reveal the safety
and benefits
of the family bed. The numbers in the
largest study on cosleeping around the world suggest that safe cosleeping reduces SIDS greatly. Most nations
with SIDS rates much lower than the United States regularly practice
cosleeping
on firm surfaces with low rates of adult smoking. Countries with
increased cosleeping frequency also show decreased rates of SIDS.
It’s become obvious in recent years that pharmaceutical companies
wield powerful influence over doctors’ prescribing habits.
Parents who like to read and
investigate are well aware of the strong ties between formula
companies and
pediatricians’ advisements.
A few years ago, it became apparent who was behind the curious
disinformation campaigns about cosleeping. In May 2002, the Consumer
Product Safety Commission (CPSC) released a weakly supported announcement
purporting the dangers of cosleeping.
Interestingly, the announcement
was sponsored by the Juvenile Products Manufacturers Association
(JPMA) — in other words, the crib industry. The crib industry
went further by providing “Safe Sleep” brochures to
Toys ‘R Us and other venues, creating a video clip for wide
media distribution, and granting continued “education” on
the topic to doctors.
Frightening
families away from safe, natural cosleeping sells more than more
cribs. Research shows that cosleeping supports breastfeeding.
Crib sleeping makes breastfeeding less convenient and more difficult;
therefore, enforcing crib sleeping sells more formula. Keep following
the progression: increased
formula feeding means increased illnesses for babies,
which means increased pharmaceutical sales.
Despite the
2002 CPSC statement about cosleeping “dangers,” the
American Academy of Pediatrics (AAP) continued to support safe
cosleeping. But now, with encouragement from SIDS
organizations that are backed by pacifier and formula company funding, the
AAP seems to have joined the anti-cosleeping bandwagon — and
has begun plugging pacifier use, as well.
The facts speak for themselves
Yet the AAP’s latest announcement is not backed by sound
scientific data. Review for yourself the summaries of key points
from the largest and most recent studies. A large portion of these
come from the AAP's own journal, Pediatrics. They include all the
relevant studies referenced in the AAP’s October 2005 journal
announcement or more current reports from the
same studies or authors

M. Lahr et al., "Bedsharing and Maternal Smoking in a Population-Based
Survey of New Mothers," Pediatrics (U.S.) 116, no. 4 (Oct
2005): e530-42.
This study on smoking and cosleeping with 1,867 women in Oregon
appeared in the October 2005 issue of Pediatrics, just before the
issue containing the big AAP announcement warning against all cosleeping.
Its authors, M.D.s and Ph.D.s, extensively analyze nine large,
case-controlled studies of bed-sharing and SIDS as well as several
other studies. These authors state that "recommendations must
be based on solid scientific evidence, which, to date, does not
support the rejection of all bed-sharing between nonsmoking mothers
and their infants."

Deaths in Kentucky," The American Journal of Forensic Medicine

Knight and co-authors examined 697 sudden unexpected infant deaths
in Kentucky from 1991 to 2000. In this report, 43% of co-sleeping
deaths occurred on sofas (36%) or waterbeds (7%). A large portion
of dying co-sleepers had been sleeping with siblings, "disinterested
caregivers" or other inappropriate partners or in over-crowded
beds.
The authors opine upon their analysis that cosleeping itself is
perhaps not dangerous but that death risks are related to unsafe
cosleeping environments, including unsafe sleep partners, partners
who smoke and unsafe surfaces and bedding.

This study examined 232 New Zealand SIDS cases and 1,200 control
cases between 1991 and 1993 for risk factors. No increased risk
of SIDS was found when bed-sharing with non-smoking mothers. There
was a 31% increased risk of SIDS for not breastfeeding (after considering
modifiable risk factors; the raw figure was 67% for increased risk.).

311, no. 7015 (Nov 11, 1995): 1269-72.
Two hundred infants dying of SIDS in Southern California and 200
control infants were studied to measure whether infants bed-sharing
with their parents were more likely to die from SIDS than other
infants. Forty-five of the 200 infants died while cosleeping: 35
sharing their parents' bed, 6 sharing a babysitter's bed, and 4
while sleeping in their mothers’ arms (this was included
as cosleeping). This represents 22.5% of the total SIDS deaths
as occurring during cosleeping — a number similar to or likely
lower than the number
of infants usually cosleeping. Smoking,
drug use and medical conditions were accounted for statistically.
The authors reported that there was "no significant relation
between routine bed sharing and the sudden infant death syndrome."

Study of Factors Influencing the Risk of Sudden Infant Death Syndrome.
CESDI SUDI Research Group," British Medical Journal (England)
319, no. 7223 (Dec 4, 1999): 1457-61.
This study looked at 325 babies who died of SIDS, including suffocation
deaths, around England from 1993 to 1995, along with 1,300 matched
controls. The highest risk of SIDS in this study, like in most
others, was associated with shared sofa-sleeping, at 49 times the
risk of sleeping alone in the parents’ room (the same number
found by Unger et al.; see Pediatrics February 2003 below). The
second-highest risk for SIDS in this study was associated with
sleeping outside of the parental room, at 10.5 times the risk of
sleeping
in the parents’ room.
Thirty-seven percent of the control bedsharers (four matched live
controls for every SIDS infant) slept between their parents, suggesting
this is the normal rate for this, while only 22% of infants dying
in bed with a parent or parents were found between the parents
at time of death — contradicting Unger's implied factor of
added danger in having the father in bed.
Sharing the parental bed at the last sleep was found to be safer
than sleeping in another room but still nearly 10 times the risk
of sleeping alone in the parental room. This is the highest reported
factor among studies. However, after the authors removed risk factors
such as prone sleeping, being placed on a pillow, being found with
head covered, smoking, alcohol, parental tiredness, overcrowded
situations and pacifier use (which was considered a risk factor
in this study), the risk of bed-sharing at last sleep was 1.35
times (or 35% higher than) that of sleeping next to the bed — a
number that the authors referred to as statistically not significant
for the strength of their figures. Still, wedging deaths from unprepared
beds (usually a considerable factor), waterbed usage and parental
drug usage were apparently not removed from this value. These are
all modifiable factors. Also not reported is how many of these
children were actually in the adult bed at time of death, rather
than for some other period during their last night.
Excluding infants under 14 weeks of age, the risk of death from
sharing sleep with a parent or parents was 1.08 times that of lone
sleeping in the parental bedroom, before wedging, drugs and other
factors are taken into consideration.

for Targeted Intervention," Archives of Disease in Childhood

This paper is a continued and extended evaluation of the CESDI
SUDI study noted above, with 325 case infants and 1,300 controls,
this time looking at the aspect of infant size at birth. This study,
like most, includes suffocation deaths in the term SIDS.
The calculated odds of SIDS for being small at birth (pre-term
or low birthweight) and bed-sharing with a smoking parent is 37
times the risk of full-sized term infants sleeping alone in the
parental room. For those born small, co-sleeping with a non-smoking
parent posed a quadrupled risk of SIDS versus sleeping alone near
the parental bed. Other risk factors are not removed from this
statistic, but clearly the tiniest babies are vulnerable to suffocation
and overheating complications when not well prevented.
Those who were not small at birth and were cosleeping with parents
who don't smoke had only four-fifths the risk of dying of SIDS
of not-small infants who slept next to the parental bed. As in
other studies, when measured, a protective effect of cosleeping
is shown statistically beyond the first 2 or 3 months, or a certain
weight, before other risk factors are even accounted for. Full-sized
infants cosleeping with a smoking parent showed nearly eight times
the risk of SIDS as those who slept alongside non-smoking parents.

While causes of deaths for 1,619 Maryland infants during 1990-2000
are examined, 930 infants comprised of 802 SIDS infants plus 128
accidental infant deaths (including suffocations) are evaluated
for sleeping locations.
Thirty-three percent of SIDS cases were found among infants who
were bed-sharing with any type of partner(s). (So
what percentage of all infants are bed-sharing?)
An additional 1.6% of the total SIDS plus accidental death cases
were diagnosed as overlayings. The literature commonly recognizes
a likely overdiagnosis of overlying resulting from opinions on
cosleeping. While only one-third of these showed physical evidence
of suffocation, such evidence is commonly not found in many kinds
of suspected suffocations.
45% of infants in SIDS deaths were found alone in cribs. An additional
3% died from defective cribs — twice that of the suspected
overlayings.

Infant Death in 20 Regions in Europe: Case Control Study," Lancet

Twenty European regions were covered during the years of 1992 to
1996, totaling 745 SIDS cases, including suffocation cases, and
2,411 controls.
Bed-sharing with a non-smoking mother was shown to have 1.5 times
the risk as not bed-sharing but sleeping in the same room, before
removing from the statistics any other risk factors such as unsafe
bedding, drug use, alcohol use (which more than doubled risk),
infants not accustomed to bed-sharing, etc. Any of this small statistical
risk of bed-sharing, with non-smoking mothers but under any other
risk factor, was only significant for infants under 8 weeks of
age. As pretty much seen across the board, once suffocation risk
from inappropriate practices is out of the picture, cosleeping
becomes safer than not.
Bed-sharing with a smoking mother was 18 times the risk of not
bed-sharing with a non-smoking mother.
No increase in infant deaths was found when mother had one to two
alcoholic drinks, versus none, but when mother had three or more
drinks, the risk of infant death (alcohol risk only found when
cosleeping) was 2.3 times the risk of sleeping with a non-drinking
mother. Although drinking statistics were obtained, the risk for
bed-sharing with a non-smoking and non-drinking mother was not
reported.

Risk Factors Among Infants Dying Suddenly and Unexpectedly" Pediatrics
(U.S.) 111, no. 2 (Feb 2003): 127-131.
This study looked at all deaths of infants under age 2 years in
St. Louis County from 1994 through 1997, totaling 119 deaths of
SIDS, accidental suffocation or undetermined causes. The question
as to why the rates of such unexplained infant deaths are several
times higher in African-Americans than in other Americans was addressed.
Twenty-one percent of sudden and unexpected African-American infant
deaths and 54% of non-African-American deaths occurred in cribs.
Twenty-three percent of “bed-sharing" deaths of African-American
children occurred while sharing sleep with another individual on
a sofa, compared to 9% among non-African-American infants.
The risk of SIDS for "bed-sharing" on a sofa was 49 times
the risk of not bed-sharing.
Thirty-three percent of African-American cosleeping deaths and
18% of non-African-American cosleeping deaths occurred when sharing
sleep with siblings — another well-known risk factor for
tiny infants.
The great majority (percentage undeterminable) of deaths outside
of cribs included modifiable risk factors such as inappropriate
or overly soft bedding, sofa sleeping, intoxicated mothers or otherwise
inappropriate sleeping partner(s). Smoking was not taken into account
in this study.
Only 15% of the unexpected deaths of all African-American infants
and 3.5% of non-African-American infants occurred on an adult bed
with their mothers alone (additional number in attendance by the
fathers is not provided in study, but their presence is usually
not statistically contraindicated) — and the majority of
these still included other known risk factors.
Forty-one percent of African-American babies in St. Louis bed-share.

This study examined all 130 SIDS cases in Alaska between 1992 and
1997. Forty-five percent of Alaskan SIDS deaths involved some form
of bed-sharing, while 35% of Alaskan infants cosleep always and
75% do so sometimes or always. (K. Perham-Hester, "Co-sleeping
in Alaska: Data from PRAMS. Executive Session of the Maternal-Infant
Mortality Review Committee," Anchorage, AK; December 1999.)
Of all the SIDS deaths in Alaska from 1992 to 1997, only one infant
death involved an infant sleeping on a safe mattress with a non-drug-using
parent (< 1% of total deaths).

Infant Death Syndrome in an Urban Population: The Chicago Infant
Mortality Study" Pediatrics (U.S.) 111, no. 5, part 2 (May
2003): 1207-14.
Data from 260 SIDS cases and 260 controls in Chicago, consisting
of 75% African-American infants, 31% Latino infants and 12% Causasian
infants, are analyzed.
Bed-sharing with one or both parents in any condition posed 1.4
times the risk of sleeping alone. This factor was stated to be
statistically non-significant. There was no compensation made for
those sleeping with an adult under the influence of drugs or alcohol,
while other studies show these to be significant risk factors in
infant bed-sharing. When other children were in the bed, the cosleeping
SIDS risk was 3.6 times the risk of sleeping alone.
Breastfeeding appeared to reduce SIDS to one-fifth the risk; however,
after accounting for factors including the mother's age, education,
marital status and prenatal care, the strength of the number became
statistically insignificant. The factors that are more typically
associated with breastfeeding are the same factors that are associated
with lower SIDS rates, but studies have not determined how much
of this result extends from breastfeeding itself.

SIDS: Bed-Sharing vs. Non Bed-Sharing" Archives of Disease

2005) .074674
This study examined 287 SIDS cases and 831 controls between 1994
and 2001 in Ireland for factors associated with bed-sharing deaths.
Bed-sharing death risks were reported to be three times greater
among low-birthweight babies. Other studies point out dangers for
young, premature infants as well. These tiny and young infants
are less able to move themselves out of a low-oxygen situation
and may not put up as much of a fuss to alert parents.
The bed-sharing death risk was 14 times greater for those with
smoking mothers. There was a doubled risk of death for bed-sharing
with non-smokers versus lone sleeping, before any other high-risk
behaviors were removed from the statistic — and a new risk
factor was discovered in this study: 50% of infants dying while
bed-sharing were not in their accustomed sleep arrangement — they
and their parents were not accustomed to bed-sharing. Removing
this 50% of impromptu bed-sharers would leave no increased risk
for customary, non-smoking bed-sharers.
Heavy blankets and comforters were found to be a major risk factor.
Bed-sharing deaths decrease with age, and babies bed-sharing over
the age of 12 months had less than half the risk of sleep deaths
than those sleeping alone. Breastfeeding bed-sharing infants had
half the risk of SIDS of non breastfeeding bed-sharers.

D. Tappin et al., "Bedsharing, Roomsharing, and Sudden Infant
Death Syndrome in Scotland: A Case-Control Study" Journal
of Pediatrics (Scotland) 147, no. 1 (Jul 2005): 32-7.
This study examined 123 SIDS and 262 control cases in Scotland
between 1996 and 2000 for association between bed-sharing and SIDS.
Suffocation deaths are included in the term SIDS here.
Sleeping alone in a separate room was associated with more than
three times the risk of SIDS as sleeping in the same room with
parents. Fifty-two percent of SIDS infants were reported as sharing
a sleep surface at some time during the night of death, but only
32% were found sharing the parents' bed at time of death. (The
use of statistics for having co-slept for some time during the
night of death is often used to make co-sleeping dangers sound
higher.)
The study does not give quantitative figures but suggests that
heavy bedding (the weight of bedding or duvet, referred to as "tog")
is a strong factor in SIDS deaths. In an earlier study of theirs,
the study authors found 81% of bed-sharing deaths relating to heavy
comforters/bedding.
Very few of the parents of infants found dead in their parents'
bed at time of death reported that this was their usual sleeping
arrangement.
This study reports an increased risk of SIDS for breastfeeding
in bed-sharing infants, but many of those infants were found dead
in cribs and were not cosleeping at the time of death; only the
number found cosleeping at time of death would have been relevant
to report. Many of the infants found dead in cribs may have been
unaccustomed to crib sleeping or too fussy to bed-share (for some
health reason), although this is conjecture.
Twenty percent of control infants shared a sleep surface during
a reference sleep. Twenty-two percent of infants found sharing
at time of death were sharing a couch. Seventy-two percent of those
bed-sharing at time of death were under 11 weeks of age.
As usual, no figure is given for the percentage of SIDS cases that
represented bed sharing with a safe parent in a safe adult bed.

in Infancy" Archives of Pathology and Laboratory Medicine

This smaller study looked at 56 cases of sudden unexpected infant
deaths or SIDS diagnoses from the files of one author doctor in
upstate New York. I find this study valuable to mention in that
the circumstances of deaths were well described and delineated
and provide a good idea of what can be assumed from untold stories
in larger studies.
Fifty-two percent of SIDS cases were among infants sleeping alone:
34% among infants alone in cribs, 9% among infants alone in adult
beds and 5% among infants alone on couches. (The other 4% were
in other solo sleeping situations.)
Twenty-five percent of all SIDS deaths occurred among infants in
an adult bed with an adult(s), in any condition. Seven percent
occurred among infants who were cosleeping with an intoxicated
adult on a bed or couch; 16% were cosleeping on a couch; and 7%
were cosleeping with a twin in a crib. (There is no evidence of
twin cosleeping to be of greater risk than separate sleeping. It
may be safer, as certain physiological advantages have been documented,
but the numbers have not been checked. Twins overall have double
the SIDS rate of singletons. A study
of simultaneous twin SIDS deaths reported eight out of 41 cases
where the twins were cosleeping. Anecdotally, cosleeping is very
high among twins.)

Medical Journal November 1993
R. Scragg, E. Mitchell et al., "Bed Sharing, Smoking, and
Alcohol in the Sudden Infant Death Syndrome. New Zealand Cot Death
Study Group" British Medical Journal (New Zealand) 307, no.
6915 (Nov 20, 1993): 1312-8.
In New Zealand, 393 SIDS cases and 1,592 controls were examined
for the interval between 1987 and 1990.
The SIDS risk for last sleep (where the infant was laid down or
spent most of the night) spent in bed with a mother who smoked
was 4.5 times the risk of having a non-smoking mother and not sleep-sharing.
For infants with non-smoking mothers who usually bed-shared in
the two weeks before their death, the risk of SIDS was 1.7, but
for those who were bed-sharing during their last sleep, there was
no risk at all found. Alcohol usage did not appear to be a risk
factor in this study.
The infants’ actual location at time of death was not reported
in this study. While sleeping with a mother with smoke in her lungs
can reasonably increase the risk of death after being removed from
bed-sharing, there is no apparent reason why in the absence of
a smoking parent usual cosleeping should increase death risk outside
of the parental bed. We have seen that some studies look at whether
bed-sharing SIDS cases occur among infants accustomed to cosleeping
or not. These studies report that deaths are most common in impromptu
or unaccustomed bed-sharing situations.
Notice in this New Zealand study that a higher rate of SIDS is
reported for regular co-sleepers but not for those cosleeping at
the night of death. It appears, as in a few other studies, that
there may be a danger factor for infants to be alone in a crib
when they are accustomed to the regulation of their parental bed-sharers.
This factor may confound many risk reports for bed-sharing deaths,
as it is usual to report based upon where the infant was first
placed to sleep, spent most of their last night or simply what
their usual sleep arrangement was, rather than where the infants
were actually found at time of death.
Pediatrics October 2003
N. Scheers, J. Kemp et al., "Where Should Infants Sleep? A
Comparison of Risk for Suffocation of Infants Sleeping in Cribs,
Adult Beds, and Other Sleeping Locations" Pediatrics (U.S.)
112, no. 4 (Oct 2003): 883-9.
This study attempts to compare infant suffocation trends (suffocation
diagnoses only, as opposed to all SIDS cases) between the 1980s
and the 1990s. While reports from James McKenna and others reveal
reasons why true SIDS should be lower when sharing sleep with mother,
suffocation accidents in adult beds are higher, as they were in
cribs before safety education about crib sleeping became widespread.
Although the great number of variables and complicating factors
(most admitted to) prevents solid comparisons, the statistical
information in this study can provide much insight into the causes
of adult-surface deaths. It studies 883 cases of infant suffocation
reported to the Consumer Products Safety Commission from the 1990s.
The numbers in this study support a risk of 20 times or more for
suffocation-only deaths while sleeping in actual adult beds versus
sleeping in cribs. This ratio is based upon an assumption that
18% of all infants are sleeping in adult beds. Yet studies suggest
that the
numbers of infants cosleeping are higher
than this number, and adding those in adult beds without co-sleeping
would make the true adult-surface sleeping number even
higher. Therefore, their risk ratio estimate is likely to be high.
There is also likely to be some portion of the deaths that were
reported as overlying that were actually SIDS prior to overlying,
making this study's risk figure slightly more overestimated. There
is no mention as to how many of these cases involved co-sleeping.
It is known from other studies that suffocation deaths are greater
in adult beds when no protective parent is present. While SIDS
deaths should be lower while cosleeping with a mother or other
protective adult, suffocation accidents are known to be higher
in adult beds, as they were in cribs before safety education about
crib sleeping became widespread.
Great praise is made in this report as to the large reductions
in crib deaths once various mandatory and voluntary safety standards
were imposed and parents were educated in making cribs safer. Oddly,
the report never makes a similar suggestion to do the same for
family beds; rather, it is suggested that any attempts to make
adult beds safer should be discouraged because they have "unproven
efficacy."
Twenty-two percent of adult-surface suffocations occurred on sofas.
More than 57% of specified-cause suffocations in actual adult beds
were due to wedging or entrapment, mostly with walls, headboards
or bedrails. Bedding, plastic and overlying are other sources of
suffocation.
Eighteen percent of the adult bed suffocations (remember — not
of all SIDS, just among those diagnosed as suffocations) are suggested
to be from overlying. It is well understood that overlying is very
likely to be over-diagnosed, since it often selected as the diagnosis
based solely upon opinions about cosleeping. Even when an infant
is found dead underneath an adult's body, there is often no means
of determining whether the adult overlaid the infant after it died
because it was no longer a warm, reactive body but rather cold
and non-responsive, more like a pillow.
AAP Views on Pacifiers
A pacifier is, of course, an artificial replacement for the mother's
nipple. Scientists have confirmed in many ways that sucking is
an important part of babyhood, in terms of emotional comfort and
security, neurological development, pain management and optimal
physiological status.
The opportunity for natural sucking is likely to be one component
of reduced SIDS rates among breastfeeding, cosleeping infants.
It has been shown in studies of preemies that providing artificial
means of sucking maintains their physiology far better than having
no such opportunity, although it does not provide as much benefit
as actual nursing at the breast, when available.
It is odd that the AAP suggests an artificial replacement for something
natural without even comparing the benefits of the natural version,
as most pacifier studies do.

Results from the CESDI/SUDI Case Control Study" Archives of
Disease in Childhood (England) 81, no. 2 (Aug 1999): 112-116.
This report was performed using the statistics from the CESDI/SUDI
study of 325 SIDS infants in England with 1,300 matched controls.
While there was no difference between the incidence of SIDS between
those who regularly used a pacifier and those who did not, there
was a slight difference in the number of infants found dead with
pacifiers vs. controls (children without): 40% versus 51%.

This report was a closer analysis of the above study, using the
statistics from the CESDI/SUDI study of 325 SIDS infants in England
with 1,300 matched controls.
This study demonstrates that the statistical odds of dying without
a pacifier when accustomed to using one is 17.5 times the risk
of not having a pacifier at all.
The SIDS/Suffocation Risk Factors for Co-Sleeping
• Bed sharing not being the accustomed sleep arrangement
• Sofa sleeping
• Smoking parent
• Unsafe space between mattress and headboard or wall
• Prone sleeping
• Parent compromised by drugs or alcohol
• Overly heavy or fluffy bedding
• Sleeping with sibling (for tiny infants) or a non-interested adult
Also, for parental bed sleeping:
• Sleeping without protective parent in room
What About All Those Crib Products?
An intriguing figure emerges from any close examination of
cosleeping and SIDS — and
it has nothing to do with who is sleeping where. This figure has to do with
crib bedding: bumpers, quilts, pillows, comforters, soft
toys and other items often
found in cribs.
In May 2002, the media trumpeted a report from the Consumer and
Products Safety Commission (CPSC) showing that 60 accidental
infant deaths (known suffocations;
not SIDS, which includes suspected suffocations) have occurred per year in
adult beds for age birth to 2 years. Much of the coverage implied
that cosleeping was
to blame, although the report did not reveal how many of the deaths actually
involved cosleeping. In fact, many experts noted that some of the reported
suffocation “accidents” were
described as “suffocations of unknown cause” and would have likely
been diagnosed as SIDS — not accidental suffocation — if they had
occurred in cribs, thus decreasing the total number of reported deaths.
Yet strangely, a strikingly similar figure also released by the
CPSC just two months later failed to create headlines. Shortly
following its report on infant
deaths in adult beds, the CPSC issued another report noting that 65 deaths
per year are reported due to crib accidents, in which cribs and
other nursery devices
collapse, strangle or cause other fatal injuries. Sixty adult bed deaths per
year, versus 65 crib accidents per year …
Yet the discrepancies in reporting don’t end there. Suspected suffocation
from inappropriate bedding materials on adult beds, which is included in the
diagnosis of SIDS, is a real danger that a true consumer protection agency would
educate the public about. However, if the CPSC were to do so, another uncomfortable
truth would have to emerge. The CPSC reported in 1999 that an average of 900
children per year were dying due to suffocation from fancy crib bedding and soft
nursery product items (a number now over 1,000 and continuing to climb) — yet
the attention remains on children sleeping in adult beds, not those sleeping
in cribs.
One-quarter to just over one-third of SIDS deaths, including
suspected suffocation, in the United States are demonstrated
to occur during cosleeping. With the other
two-thirds or more of SIDS deaths occurring in cribs and other solo sleeping
situations, we come to the amazing realization that half of these — a
full one-third of all SIDS deaths — are reported by
the CPSC to be caused by overly fluffy, soft and otherwise inappropriate nursery
bedding, bumpers, pillows and comforters. Both the CPSC and the AAP have been
aware of these figures for a long time, but the crib industry is still allowed
to flagrantly market these items to families with crib-sleeping infants. These
dangers need to be eliminated now — in cribs, in family beds, in strollers
and in other infant sleep situations.
These crib products-related deaths are particularly troublesome given the fact
that over the last decade, each of the top five juvenile product manufacturers
has had at least nine product recalls. Consumers Union is supporting legislation
that would require pre-market testing of all durable children's products by an
independent entity. This legislation was initiated by a leading child safety
advocacy organization, Kids in Danger, whose founders' son was killed in a recalled
portable crib provided at his day care center.
Despite the fact that the CPSC recommends that infants under
a year old should be sleeping in a crib that’s nearly bare — with just a mattress and
fitted sheet — retailers are still displaying cribs made up with all
the trimmings. Despite the fact that more than 1,000 children a year are dying
from
these unnecessary trappings, the CPSC has not moved to restrict their prolific
marketing.
Soft bedding can suffocate infants, whether they are in cribs or in beds with
their mothers. Soft bedding is proven to kill infants; the presence of a conscientious
and safe co-sleeping mother is not.

So How Many Actually Are Cosleeping?
According to the gathered statistics from available studies:
• 77% of mothers in Oregon bed-share at least sometimes. 35% bedshare
usually or always. (M. Lahr et al., "Bedsharing and maternal
smoking in a population-based survey of new mothers," Pediatrics (U.S.)
116, no. 4 (Oct 2005): e530-42.)
•
41% of African-American babies in St. Louis bed-share. (B.
Unger et al., "Racial and modifiable risk factors among
infants dying suddenly and unexpectedly," Pediatrics (U.S.)
111, no. 2 (Feb 2003): 127-131.)
•
13% of U.S. infants bed-share usually
or always; 20% share half the time or more; and
almost 50% were sharing sometime during the two weeks before
the survey.
This study admits to under-representing poor families, leading
to an underestimation of bedsharing percentages. (M. Willinger
