8. Breast Milk Composition Differences
(dynamic)
•Gestational age at birth (preterm and full term)
•Stage of lactation (colostrum and mature milk)
•During a feed (foremilk and hindmilk)

9. COLOSTRUM
Property
•Antibody-rich
•Many white cells
•Laxative
•Growth factors
•Vitamin-A rich
Importance
•Protects against infection and
allergy
•Protects against infection
•Clears meconium; helps prevent
jaundice
•Helps intestine mature; prevents
allergy, intolerance

infection (such as measles and
diarrhoea); prevents vitamin A
related eye diseases

11. Why should I breastfeed?
-the natural choice for BABIES
-the natural choice of MOTHERS
-the natural choice for the
ENVIRONMENT

12. -The natural choice of
MOTHERS

13. •Nursing uses up extra calories,
making it easier to lose pounds of
pregnancy
•Breastfeeding lowers the risk of
breast and ovarian cancers
•Breastfeeding can help you bond
with your baby
•Save more money, easy,
convenient and more portable
•Breastfeeding has contraceptive
effect

14. The natural choice for
BABIES

15. •Breast milk is the most complete
form of nutrition for infants
•Breastfed babies score higher on
IQ tests
•Ensuring your baby has only
breastmilk for at least 6 months
may help minimize allergy
problems
•Babies breastfeed for comfort
and closeness as well as to
satisfy their hunger and thirst

21. Lower risk of obesity.
•A study in Germany found that among 9357
children aged 5 and 6 there was an over 5 times
difference in the prevalence of obesity among
those children never breastfed compared to
those breastfed for over one year
•The length of time an infant was breastfed was
inversely proportional to the prevalence of
childhood obesity
von Krieset al

22. The natural choice for the
ENVIRONMENT

23. •The production and feeding of breastmilk have a
far lower impact on our environment and the
world resources than ANY alternative feeding
method
•Breastfeeding saves food resources, fuel and
energy
•No packaging is required and NO CHEMICALS
are needed for preparation and disinfection

24. Benefits for the Hospital
•Warmer and calmer emotional environment
•No nurseries, more hospital space
•Fewer neonatal infections
•Less staff time needed
•Improved hospital image and prestige
•Fewer abandoned children
•Safer in emergencies

25. Risks of Artificial Feeding

27. RISK OF ARTIFICIAL FEEDING
Baby
•More likely to fall sick
•Increase risk of obesity
•More diarrhoeaand
respiratory infections
•More allergy and milk
intolerance
•Increased risk of chronic
diseases
•Risk of otitis media
•Risk of NECin preterm
Mother
•Pregnant sooner
•Increased risk of ovarian
and breast cancer
•Interferes with bonding
•Hip fractures in older age

28. Dangers from the Use of Breast-milk
Substitutes
•Powdered Infant formula is not sterile and during
manufacture may be contaminated with bacteria
such as EnterobacteriaSakazakii& Salmonella
enterica.
•WHO has developed guidelines for careful
formula preparation in order to minimize the risk
to infants
Adapted from:16 guidelines for the safe preparation, Storage and Handling of powdered Infant
Formula, Food Safety, WHO(2007)

29. Impact on Society
•Possible increase in use of health care
services, and increase health care costs, both
as infants and later.

30. Impact on Society

31. Scenario
•You are speaking to 22 years, Jessica,
beautician, who has delivered healthy 2.7

is passing pink coloururine. She had only
changed diaper 2 times since birth.

32. Your role is to:
•Ask open-ended questions to find out her thoughts and
feelings about her anxiety
•Use probes to better understand what she means.
•Affirm her feelings and release her anxiety
•Your role is to communicate about her concerns and

65. Lower risk of allergies.
•It is generally agreed that allergies are less
common in completely breastfed babies. A recent
study in Sweden in which a birth cohort of 4089
infants was followed prospectively found that
exclusive and partial breastfeeding reduced the
risk of allergic disorders
•Children exclusively breastfed during four months
or more exhibited less asthma (7.7% vs. 12%),
less atopic dermatitis (24% vs. 27%) and less
allergic rhinitis (6.5% vs. 9%)
Kull et al.

66. Risk of Allergy and Milk intolerance
•Artificial milk has different proteins from human
milk –slow and difficult to digest
•Some babies develop intolerance to proteins in
formula and develop rashes, diarrhea and other
symptoms

67. Artificial Feeding and Risk of Allergy
•Prospective study on Finnish infants of atopic
parents for 17 years found that the prevalence of
atopywas highest in the group of children not
breastfed at all or were breastfed less than a
month

68. Increased Risk of Chronic Diseases
•Study done in Amsterdam on 625 adults aged 48-53

those who were exclusively breastfed

blood pressure and obesity. Arch Dis Child 82:248-52

69. Risk of Otitis Media
•A study in Sweden found that breastfed infants
had less otitis media than artificially fed infants
•At one to three months of age,6 % of the weaned
infants had otitis media, compared to only 1% of
the breastfed infants
Anaianssonet al

70. Necrotizing Enteritis in preterm infants
•926 preterm infants were studied, 51 of whom
developed NEC.
•Exclusively formula fed infants were 6 to 10
timesmore likely to develop NEC than those
who received breast milk.
•Although NEC is rare in babies over 30 weeks
gestation, it was 20 times more common if the
baby had received no breast milk.
Adapted from Lucas A & Cole TJ (1990). Breast milk and neonatal necrotising
enterocolitis,Lancet336:1519-1522

71. Risk of Breast cancer
•This multi-centretrial in the USA included more
than 14000 pre-and post-menopausal women. It
concluded that breast cancer risk was 22%
lower among pre-menopausal women who have
breastfed than among those who have never
breastfed.
Newcomb PA et al. (1994). Lactation and a reduced risk of premenopausal breast
cancer. New Engl J Med 330: 81-87

72. Risk of hip fractures in elderly women
•In one study of 311 cases of hip fractures in
women over 65 years of age, it was found that
parous women who had not breastfed had twice
the risk of hip fractures as nulliparous women
and those who did not breastfed
