we as Leaders can benefit by looking beyond our
cultures and our time period to gain a more in- depth
understanding of what is truly normal and natural human behavior.
Katherine Dettwyler, an anthropologist, has drawn attention to
this subject through her article, A Time to Wean,
(Breastfeeding Abstracts, August 1994). Here is part of her answer
to the question of the "natural" age of weaning in
humans:
According to the research of Smith (1991), many primates wean
their offspring when they are erupting their first permanent
molars. First permanent molar eruption occurs around 5.5 to 6.0
years in modern humans. It is interesting to note that
achievement of adult immune competence in humans also occurs at
approximately six years of age, suggesting that throughout our
recent evolutionary past, the active immunities provided by
breast milk were normally available to the child until about
this age (Frederickson).
Our evolutionary past has produced an organism that relies on
breastfeeding to provide the context for physical, cognitive and
emotional development. The non-human primate data suggest that
human children are designed to receive all of the benefits of
breast milk and breastfeeding for an absolute minimum of two and
a half years, and an apparent upper limit of around seven years.
Natural selection has favored those infants with a strong,
genetically coded blueprint that programs them to expect nursing
to continue for a number of years after birth and results in the
urge to suckle remaining strong for this entire period.
In her book, Breastfeeding: Biocultural Perspectives,
Dettwyler theorizes that the six-year nursing practice for humans
began to be modified, first by the use of fire for cooking
(one-half to one million years ago) and then even more
significantly by the domestication and processing of grains via
pounding and grinding, both of which provided alternatives to
uncooked vegetation and raw animal foods. It is interesting to
note that the hunter/gatherer lifestyle represents more than 99.9
percent of human existence on earth and that agricultural
societies have existed for only about the last 10,000 years.
Ethnographic studies of hunter/gatherer and other pre-
industrial societies show that while the duration of lactation
varies considerably between cultures and between individual
children within a culture, the average duration is between three
and five years of age. Here are some examples from Wickes' 1953
survey of various tribes: Australian aborigines, two to three
years; Greenlanders, three to four years; Hawaiians, five years;
Inuit, around seven years.
Lactational duration is just one of many cultural variations in
breastfeeding practices. Patricia Stuart-Macadam, writing in
Breastfeeding: Biocultural Perspectives, informs us that the !Kung
San of the Kalahari desert in Southern Africa breastfeed
frequently and intensively, "giving the breast about four
times an hour during the day and several times at night for at
least the first two years of life." This practice has a
significant child-spacing effect with conception occurring on
average 35 months postpartum, resulting in a birth interval among
the !Kung of almost four years.
Nature's Norm
Such frequent suckling may indeed be nature's norm, reports
Sheila Kippley in her book, Breastfeeding and Natural Child
Spacing, as it is true of both chimps and gorillas as well as
representative of a number of human cultures living in natural
conditions. The Gainj of New Guinea nurse their infants at an
average interval of 24 minutes. For their 3-year-olds, the average
interval between nursings is 80 minutes. It is interesting to
compare these practices to the standard recommendation given to
new mothers today of 8 to 12 nursings in a 24-hour period.
In a thought provoking article, "The Concept of Weaning:
Definitions and Their Implications" (Journal of Human
Lactation, June 1996), Ted Greiner points to research in northern
Bangladesh where children who were breastfed at 3-4 years of age
received the breast 9-10 times a day and those who were still
breastfed at 4-5 years of age received it 7-9 times a day. Greiner
comments, "Although the quantity of breast milk was not
measured, this sucking frequency can be assumed to maintain a
relatively high level of breast milk production (as indeed it does
in women who relactate), and should hardly be termed 'token
breastfeeding."' We seem to know so little about what is
normal nursing behavior for the four- to five-year-old that this
cross-cultural information can be very reassuring to a mother who
is wondering about her child's nursing behavior.
In her book, Mothering Your Nursing Toddler, Norma Jane
Bumgarner gives us this glimpse into the history of the decline in
breastfeeding duration in English-speaking countries. She reports
that according to a study of advice given to mothers by doctors
from 1550 to 1900:
It was not until 1800 that most of the popular English
writings on child care recommended weaning as young as 12
months. Even in 1725, writers commented with disapproval on
nursing four- year-olds, an indication that a significant number
of eighteenth century four-year-olds were still receiving love
and comfort at their mother's breast. By 1850 most
"experts" were recommending weaning by 11 months. At
this time it was the nursing two-year-olds seen by child-care
advisors who drew official frowns. It is enlightening how
closely these changes in recommended patterns of child care
parallel other changes in family life that accompanied the
Industrial Revolution in England and the United States.
Bumgarner reports these other interesting pieces of history:
In ancient India, influenced by the belief that the longer a
child nursed the longer he would live, mothers usually nursed
their children as long as possible, often seven or even nine
years sometimes. In Tsinghai, China, mothers observed in 1956
were still nursing for several years, five years not being
unusual, or until another child was born. In Inner Mongolia in
1951, children nursed two or three years, nor was it rare that a
six- or seven-year-old would want to nurse for a bit of
reassurance.
Kathleen Huggins and Linda Ziedrich, in The Nursing Mother's
Guide to Weaning, give an interesting glimpse into weaning
practices of other cultures. In one account a Sioux mother
"came to school at recess to nurse her eight-year-old boy
because he had a cold." And they comment "this wasn't a
very remarkable occurrence in her culture; the average nursing
period among the Sioux, traditionally, was three to five
years."
Within Western cultures there have been significant regional
differences in breastfeeding practices. While "experts"
in England were recommending weaning as early as 12 months in
1800, Gabrielle Palmer notes in her book, The Politics of
Breastfeeding, that "in East Lincolnshire women were
reported to suckle their children until they were seven or eight
years old even in the 1820s."
Though it is clear that the majority of women worldwide and
throughout history have nursed their children into toddlerhood and
beyond, women who choose to do so today may face an uninformed and
frequently critical audience. Therefore many choose to make sure
that they limit who sees and who knows, taking greater care as the
child grows older. Given this climate it is a highly select group
of mothers who nurse their children beyond toddlerhood.
Social Pressures
Because of the social criticism and resulting secrecy, it is
hard to get an accurate picture of just how many children are
continuing to nurse this long. Often the last nursings to be given
up occur in bed and so are hidden from all but those who share the
bedroom. It must be difficult even for the anthropologist in a
native tribal village to get an accurate picture of when nursing
has completely ended.
Older nursing children as well as mothers feel the social
pressures. They are often very aware that other people just don't
understand. Privacy may be even more important to the child than
it is to the mother. Knowing other children their age who are
continuing to nurse is helpful. Reading stories about other
nursing children also helps to normalize it. Unfortunately these
stories are not widely distributed or well known. My daughter has
asked me several times to reread stories of older nursing children
from HARVEST, Area Leaders' Letter of LLL New York West, USA. She
chose to have a weaning party after being inspired by one of those
stories.
Given social criticism, people who are unfamiliar with the
practice of nursing beyond infancy may wonder why mothers would
want to continue to nurse through toddlerhood and beyond. As
Leaders we can help mothers answer this question confidently.
Mothers find many practical advantages in nursing. As a parenting
tool it is useful when easing the exhausted child into sleep or
soothing both mother and child after the storm of a tantrum has
passed by. During illness, breast milk may be the only food or
drink that a child will take or can keep down and digest. It can
make the difference between a dehydrated child needing
hospitalization and a sick, but well-hydrated, child at home in
mother's arms nursing through a potentially serious illness.
Health Benefits
The adverse health effects of weaning a child before or during
toddlerhood are well documented for Third World countries such as
Guinea-Bissau, where children who were no longer breastfed at ages
12 to 35 months had a 3.5 times higher mortality than did their
peers who continued to breastfeed. There is a lack of this type of
comparative research between breastfeeding toddlers and
preschoolers and their already weaned peers in economically
advanced countries. The negative impact of early weaning on
children's health is not as dramatically evident but in time it
may prove to be significant.
The scientific evidence on extended breastfeeding is just now
beginning to accumulate. A number of the health benefits are now
being found to be related to the length of nursing with an
increasing amount of benefit correlating with increased duration.
This is the case, research has indicated, with breastfeeding's
protective effect in maternal breast cancer, osteoporosis,
childhood ear infections and malocclusion anomalies (misaligned
teeth).
Katherine Dettwyler reports that "a wealth of scientific
evidence exists documenting that the benefits of breastfeeding
(and the risks of artificial feeding) continue for as long as the
infant nurses. Aside from the health concerns, there is now
evidence that the longer a child breastfeeds, the higher that
child's IQ score and school grades will be in later years, with a
dose effect evident even beyond two years of nursing."
The word "benefit" is perhaps misleading here, for
these "benefits" are what nature intended to be the
human norm. Breastfeeding is normal. It is artificial feeding
substitutes and premature weaning that are, in fact, abnormal from
a biological viewpoint. It is these abnormal practices that place
the child at increased risk of illness and compromised
intelligence.
For many nursing couples, by the time the child reaches
toddlerhood, nursing is a well-established part of their
relationship. We can help mothers to feel confident in
acknowledging that their breastfeeding relationship is mutually
satisfying: highly cherished by the child and often by the mother
as well. For mothers it is a mode of giving both nurturance and
sustenance. For both mother and child nursing is a momentary
retreat from the increasing separateness of their lives, back to
the closeness they shared when the two were one.
Nursing Through Toddlerhood and Beyond
Special meeting discussion questions:
- While it is clear that nursing a child beyond the first 12
months of life is something we have in common with the
majority of mothers throughout history, in many cultures we
stand out as different. While we have been able to find
support, we also may face criticism. How do you feel about
this criticism? How do you deal with it?
- We want to meet our child's needs and we want to promote the
normalcy and healthfulness of nursing without offending others
or becoming a target of criticism. It is a tricky balance to
achieve and we each need to find our own comfort level. How do
you handle the issue of nursing a toddler in public?
- Sometimes our partners or other close relatives have a
different outlook on continued nursing. How do you manage
these differences?
- Children can be demanding. At times it may feel that your
child's demands to nurse are excessive or inappropriately
interrupting your activities. How do you balance your child's
needs and wants with your own?
- When we choose to limit nursing or decide to wean
completely, how can we help our children handle their feelings
of loss?
- The nursing child may be keenly aware that peers or adults
disapprove of continued nursing. How can we protect our child
from social disapproval and help him/her handle the situation
constructively?
- What do you see as the benefits of nursing through
toddlerhood and beyond?
