Western Perceptions of, and Approaches To, Caring For
Baby?
Whose baby is it, anyway?
How and when did parents give up their rights to make decisions about how they would care for
their infants? Or Did we?
Do we ..abdicate decision making to outside medical authorities?
Why do we seem to care so much that others approve of what we do with our infants? How did
Western parents lose their own confidences in how to be a “good” parent?

Infant Care Is A “Moral Good”The kind and nature of parental care is critically
judged by community members based on societal values..roles of men, women and children…

What’s “good”
parenting?
What is safe?
What problem is worth solving?

if...sleeping alone through the night is “good” for
babies
then “good” babies sleep alone, don’t they?

cultural influences on infant touching
• “ In the western world it is perhaps a great advantage for an infant to have a sensitive skin or diaper rash or some other dermatological disorder, for then, at least, it can be assured of receiving something resembling an adequate amount of cutaneous stimulation” (Montagu :1986:247)
![Page 7: Caring for parents](https://reader037.vdocuments.mx/reader037/viewer/2022110120/55843168d8b42a0b6d8b5125/html5/thumbnails/7.jpg)
Until recent, western historic periods, no human parents ever
asked:
Where will my baby sleep, how will I lay my baby down to sleep, and
how will I feed my baby?
most human parents still don’t!
![Page 8: Caring for parents](https://reader037.vdocuments.mx/reader037/viewer/2022110120/55843168d8b42a0b6d8b5125/html5/thumbnails/8.jpg)
For the human infant the three functionally inter-related (adaptive) components of normal, healthy infant sleep include:
• Sleep location – (next to mother for social or co-sleeping behavior
involving on-going sensory exchanges, monitoring and mutual regulation)
• Nighttime feeding – exclusive breast feeding
• Sleep position– Back (supine)
![Page 9: Caring for parents](https://reader037.vdocuments.mx/reader037/viewer/2022110120/55843168d8b42a0b6d8b5125/html5/thumbnails/9.jpg)
The cultural dismantling of this biological system led to the deaths of
thousands of western infants from, SIDS, accidental asphyxiations and/or other
SUDI (i.e. from social sleep …to solitary infant sleep--
from breast feeding …to bottle-formula feeding
from supine …to prone infant sleep position

American Academy Of Pediatrics New SIDS Prevention
Recommendations
proximate but separate sleep for baby;
no side position sleeping;
cuddling but no bedsharing
pacifers for sleeping infants, after breast feeding is established;
more holding and carrying

Historical Forces Effected Western Infancy and How We Think About Infant Development
• rise of child care experts replace maternal confidence
• emphasis on technology, rather than on bodies to nurture;
• emphasis on “average expectable outcomes” per any given behavioral parenting strategy..one-size-should- fit all;
• emphasis on social values and ideologies (not biology) to guide research and conclusions..medical care of infants;
• social constructions of infancy, not /biological evolutionary;
• “Science” of infant feeding (bottle-formula feeding) and sleep pediatrics became one and the same with…
• mutually reinforcing moral ideas about who infant should be, or become, rather than who they are…and how husbands and wives should relate vis a vis distance, authority and separation from children…also, touch =sex?

Babyhood…….by Paul Reiser
“Getting your child to sleep becomes a blinding obsession. I myself would often loose sight of the larger picture.What is the actual goal here? Constant sleep? No awake time? Zero consciousness?
I mean, we must accept that at some point babies have to be awake.They did not come to the planet just to sleep. Are we determined to get them asleep just so we can get a taste of what life was like before we had a kid?
Because, if we are, then why did we have a kid? Just to lie there to look soft and fuzzy? We could have gotten, say, just a peach. A St Bernard? A narcoleptic houseguest?
Or why not just a chenille bathrobe? Chenille bathrobes are fuzzy and just lie there”?

“…SLEEPING IN YOUR BED CAN MAKE an infant confused and anxious
rather than relaxed and reassured. Even a toddler may find this repeated experience
overly stimulating”
really?
R. FERBER (1886,1999) SOLVE YOUR CHILD’S
SLEEP PROBLEMS

Culture Producing Science Producing Culture: How A Folk Myth Achieved Scientific Validation
“Scientific” validation of solitary
infant sleep as “normal” and
“healthy”
#1: Initial test condition—infant sleeps alone, is bottle fed, and has little or no parental contact
#2: Derive measurements of infant sleep
under these conditions
#3: Repeat measurements across ages, creating an “infant sleep model”
#4: Publish clinical model on what constitutes desirable, healthy infant sleep.
#5: To produce “healthy” infant sleep, replicate the test condition
![Page 18: Caring for parents](https://reader037.vdocuments.mx/reader037/viewer/2022110120/55843168d8b42a0b6d8b5125/html5/thumbnails/18.jpg)
• devoid of the “relational” familial factors (where baby sleeps and feeds as regards parental emotions and goals;)
• devoid of intrinsic (infant) factors (temperament, personality , sensitivities);
• categorizes infant’s inability to follow cultural model as…”disease”, sleep disorder, immaturity, and, thus, infant becomes a “patient”;
• promotes one- size- should- fit- all; • promotes one sleeping arrangement as a moral issue
and gives it a specific set of inappropriate meanings;
The western medicalized model of infant sleep fails miserably!

Nothing an infant can or cannot do makes sense, except in light of mother’s body

compared with other primates.. neurological age of the human neonate
at birth is rolled back… hence….
relatively speaking, all human infants might be considered “preemies”, non-
ambulatory, unable to cling, incontinent, unable to speak, keep warm, reason,
discriminate,attach social meaning to on-going events….

Primitive “Mothering” Reptiles
• The antecedents to mammalian parenting was likely an egg laying--dedicated, protective mother who shared a nest, den or burrow--who protected and retrieved, rather than fed.
![Page 34: Caring for parents](https://reader037.vdocuments.mx/reader037/viewer/2022110120/55843168d8b42a0b6d8b5125/html5/thumbnails/34.jpg)
Female duck-billed platypus
• Incubates eggs safely inside a grass-lined burrow;
• Sealed up with their mother, hatchlings feed on milk dripping from hairs surrounding a teatless milk-producing gland

Biology of Mother’s Milk Predicts Contact and Cosleeping Behavior
• Feed and Leave Species– (Ungulates)
• High fat• High protein• Low carbohydrate
• High calorie = long
feeding interval;
(to avoid predators nested infants do defecate or cry in mother’s absence)
• Contact, Co-sleeping, And Carry Species– (Primates—Humans)
• Low fat• Low protein• High carbohydrate
• Low calorie = short feeding interval;
(carried infants cry in mothers absence and defecate spontaneously)

Hidden Regulatory Mechanisms(Myron Hofer/Martin Reite)• a given interaction may be guided and even
determined by processes hidden to observation; nutritional status of infant, heat, smell, touch, vestibular;
• repeatedly delivered sensory regulation may have cumulative effects which influence adult roles and behavior by way of:
• internal state responses by baby to caregiving behavior (blood pressure, satiation, anxiety, breathing, heart rate) may be altered by specific aspects of their relationships (labile traits) like being touched, spoken to, and fed frequently (neuro-developmental, long -term effects)..

The Complex History of Infant Sleeping Arrangements In Western Industrial Societies Is Reduced To Simple Understandings Congruent
With Present Cultural Beliefs:
• inevitable suffocation/overlying/SIDS
• inevitable psychic damage to infant
• inevitable rupture to conjugal (husband/wife) relationship
• inevitable prolonged dependency of infant/ child
• inevitable lack of autonomy in infant/child
– NOTE: not one controlled scientific study documents the benefits of solitary infant sleep, or the alleged deleterious social/psychological/physiological consequences of safe cosleeping with breast feeding

Face-to-Face: Maternal Contribution to
Infant CO2 Environment • 1) 12 RB mother-infants on bedsharing
night (BN) spent 64% of their time face-to-face with infant at distances less than 20 cm. 2) concentrations of CO2 in air were measured in six young women at distances of 3, 9, 18, and 21 cm. Room was .04 % CO2 concentration and 2.36% (3cm) and < 4% (under a blanket).

Hidden regulatory mechanisms.. calming a baby by “shhhhh..ing”
A universal practice! • prenatal sensory experiences--fetus hears
rhythmic “shhoosh--sha” as blood pulses by infant’s ear every .10 of a second following maternal heart contraction..

Evidence -Based Science:
Infants sleeping alone in a room by themselves are at least twice as likely to die from SIDS than are infants sleeping in the
company (same room) as a committed adult caregiver…

Public Health Tips
• Infants encounter several different sleep environments ..regardless of how the parents classify themselves…need safety information on all of them, including safe bedsharing
• “safe “ bedsharing is not an oxymoron…(despite claims to the contrary…)there is an enormous range of safety factors that differentiate bedsharing environments…
