My husband did this one last week. I thought that many people would
find it interesting.
The osteoporosis and breastfeeding references are still available
by direct email request. I think it is too long to post in its
entirety.

Title: Nipple confusion: toward a formal definition.
Source: Journal of Pediatrics. 126(6):S125-9, 1995 Jun.
Abstract
The purposes of this article are to introduce a formal definition of
nipple confusion and to propose various hypotheses concerning its cause.
The term nipple confusion refers to an infant's difficulty in achieving
the correct oral configuration, latching technique, and suckling pattern
necessary for successful breast-feeding after bottle feeding or other
exposure to an artificial nipple. Many early breast-feeding failures are
attributed to nipple confusion, although scientific data are lacking to
document its prevalence, the mechanisms involved, or various factors that
predispose an infant to this phenomenon. Two classifications of nipple
confusion are recommended to distinguish the impact of artificial nipples
during the newborn period from their influence after breast-feeding is
well established. Maternal and infant risk factors making an infant more
susceptible to nipple confusion are discussed. Future studies are planned
to help elucidate the nature of nipple confusion and identify the
circumstances under which infants are most vulnerable to this phenomenon.
Meanwhile, it would seem prudent for clinicians to identify newborns at
risk for nipple confusion and to minimize the use of bottle feedings in
such babies. Medically indicated supplements in the early days of life
could be provided by alternative methods, such as cup, spoon, or dropper
feeding, until breast-feeding can be established.

Title: Breastfeeding promotion: feeding the low birth weight infant.
Source: International Journal of Gynaecology & Obstetrics.
31 Suppl 1:57-9; discussion 67-8, 1990.
Abstract
Though there is still some reluctance to use human milk for low birth
weight infants, we have shown that it is possible exclusively to feed
these infants on milk from their own mothers. The infants have adequate
weight gain and are less likely to get infections, especially
gastrointestinal and respiratory. It is possible to sustain lactation
through manual expression during the period that the mother is not nursing
her infant directly on the breast. A cup rather than a bottle can be used
to feed these small infants. The mothers are thus encouraged because the
infant does not suffer nipple confusion with a bottle and they continue
breastfeeding after discharge from the hospital.

Title: Factors influencing breast-feeding among adolescents.
Source: Journal of Adolescent Health Care. 9(6):470-3, 1988 Nov.
Abstract
During a 15-month study period, 244 adolescent mothers under 18 years of
age were surveyed, of whom 53% elected to breast-feed. A subset of 60
primiparous breast-feeding adolescents were studied regarding the
influence of several factors on the duration of breast-feeding. An
attitude questionnaire was administered in the hospital within 48 hours of
delivery. Follow-up interviews were obtained by telephone or in person at
approximately 2 weeks and 2 months after birth. Eighty-three percent made
the decision to breast-feed before the third trimester. Thirty-five
percent discontinued breast-feeding within the first postpartum month, the
most common reason being "nipple confusion" in the infant; 22% nursed for
more than 1 month but less than 2 months, and 43% breast-fed for 2 months
or more. None of the variables examined (maternal age, ethnic group,
education level, involvement of the baby's father, timing of the
breast-feeding decision, intended duration of breast-feeding, age at which
formula supplementation was started, or availability of maternal support)
was predictive of the duration of breast-feeding. Contrary to adolescent
stereotypes, 65% of mothers chose breast-feeding because it was "good for
the baby," and 67% identified the "closeness" of the nursing relationship
as the most enjoyable part of breast-feeding. Twenty-eight percent cited
modesty issues about breast-feeding as the greatest disadvantage, and 17%
returned to work or school within the first 2 postpartum months, posing
additional obstacles to breast-feeding. Our data suggest that adolescents
are receptive to breast-feeding, but they may require close follow-up and
anticipatory guidance tailored to their individual needs.(ABSTRACT

Title: Variations in intra-oral stimulation and nutritive sucking.
Source: Child Development. 47(2):539-42, 1976 Jun.
Abstract
Sucking records were made from 24 infants, aged 3-4 days, fed small
amounts of their usual formula from nipples of different sizes (5/16-,
8/16-, and 11/16-inch diam). Polygraphic and observer measures showed that
the large nipple elicited fewer sucks and a slower sucking rate; 5 infants
seen on 2 successive days showed a more marked nipple preference on the
second day. The results show that intra-oral stimuli control sucking for a
nutriment in much the same way as they have already been shown to control
nonnutritive sucking.
