This document discusses the benefits of breastfeeding for both infants and mothers. It provides details on the nutritional composition and bioactive components of human milk, which contain antibodies, growth factors, and other properties that protect infants from disease and promote healthy development. Breastfeeding is associated with lower risks of gastrointestinal infections, respiratory illnesses, and conditions like leukemia in infants. For mothers, breastfeeding aids postpartum weight loss and reduces the risks of diabetes, breast cancer, and ovarian cancer. The document emphasizes exclusive breastfeeding for the first 6 months as the best source of nutrition for infants.

1. Breast feeding
1. 1. MOTHER’S MILK DR PRIYANKA GUPTA RESIDENT II DEPARTMANT OF PEDIATRICS
2. 2. BREAST FEEDING A WINNING GOAL FOR LIFE
3. 3. Role of a pediatrician • They should be able to answer • Why ? • How? • How long to
continue ? • Contraindications to breastfeeding?
4. 4. Why to breast feed? • Good for the baby • Good for the mother • Good for the nation
5. 5. Mother’s Milk – The best milk for Infant Under any circumstances, “Mother’s Milk” is the
ideal food for infant. No other food is required till 6 months of age.
6. 6. Why mother’s milk??? The mother’s milk: 1. Always available – No preparation time. 2.
Proper temperature. 3. Clean & Fresh. 4. Free of contaminating agents. 5. Cheap.
7. 7. Breast is best? • Contains all the nutrients , growth factors and hormones that an infant
needs in the right amounts . Its composition changes as the baby grows. • Anti infective
properties: Macrophages, lymphocytes and polymorphs, Secretory IgA, Lyzozyme,
Lactoferrin (inhibits growth of E.coli.), anti-viral agents.
8. 8. Advantages of Breast Feeding To the infant: 1. Meets the full nutritional requirement of
infant. 2. Less incidence of allergy & intolerance. 3. Contains antimicrobials factors against
various diseases.
9. 9. Infant health outcomes Strong or causal evidence: • GI tract infections • Upper and lower
respiratory tract infections • Otitis media • Acute lymphoblastic leukemia • Sudden infant
death syndrome Evidence in development: • Cognitive development • Atopic allergies •
Asthma • Other pediatric cancers • Childhood obesity
10. 10. Maternal benefits of breastfeeding • Breastfeeding may confer immediate and long term
benefits to mothers, especially if recommendation for exclusivity and duration are met. •
Such benefits may strengthen motivation and commitment to breastfeeding
11. 11. Maternal benefits of breastfeeding Reason to Initiate breastfeeding • Reduce maternal
bleeding after delivery 27% deaths are due to postpartum haemorrhage • involute uterus •
Facilitate positive metabolic changes • Reduce stress • Delay ovulation
12. 12. Maternal benefits of breastfeeding Reason to continue breastfeeding • Increase
postpartum weight loss • Prolong lactational amenorrhea • Decrease visceral adiposity •
Reduce type 2 diabetes risk • Reduce cardiovascular risk • Reduce breast cancer risk •
Reduce ovarian cancer risk
13. 13. Maternal health outcomes Strong or causal evidence: • Postpartum weight loss •
Lactational amenorrhea • Breast cancer Evidence in development: • Ovarian cancer • Type 2
diabetes • Cardiovascular disease • bonding

• MOTHER’S MILK VERSUS TOP FEED • FOREMILK VERSUS HIND MILK
16. 16. Mother’s MILK • Dynamic, multifaceted fluid • Contains nutrients and bioactive factors
17. 17. Colostrum in Human Milk • Thick, yellow fluid • Provides 58-70 cal/100 ml. • High in
protein, electrolytes, sodium, potassium, chloride and vitamin A. • Low in fat and
carbohydrate. • Lactobacillus bifidus factor. • Contains antibodies immune system cells.

2. 18. 18. Colostrum Benefits of colostrum feeding: 1. Perfect food for infants in initial days. 2.
Laxative effect – clears infant’s intestines of initial stools; prevents jaundice. 3. Contains
leukocytes which prevent infection. 4. Contains IgA which also provides immunity.
19. 19. Change in Milk Composition During Feeding • Foremilk – Released first – Higher in
carbohydrate – Lower in fat • Hindmilk – Resembles cream – Higher in fat – Lower in
carbohydrate – Released after 10-20 minutes into the feeding

23. 23. Preterm Vs term milk • Preterm milk contains more protein and fat • Preterm milk
contains higher levels of EGF than term milk • BDNF can enhance peristalsis, a function
frequently impaired in preterm gut. • Preterm milk contains less VEGF than term milk Liao Y,

24. 24. Composition of breast milk vs cows milk • Carbohydrate: Human milk 7% Cows milk
4.5% lactose • Fat : mother’s milk is rich in PUFA, • Minerals Cows milk contains more of all
the minerals (esp sodium, calcium and phosphate) except iron and copper. • Vitamins Cows
milk is low in vitamin C and D but more thiamine and riboflavin.
25. 25. Mature Human Milk • Provides 65kcal/100ml • High in linoleic acid and cholesterol
content for brain development • High in fat content and lactose • Docosahexaenoic acids
(DHA) – Used for synthesis of brain tissues, central nervous system and eyes • DHA and
cholesterol not found in human milk substitutes
26. 26. Mature Human Milk- PRO • Protein – Low content • Dependent on infant’s age – Antiviral
and antimicrobial effects – Whey (lactalbumin and lactoglobulin) • Major protein in mature
milk • Easily digestable • Ideal ratio of cystine, taurine and methionine to support
development of CNS AND PNS
27. 27. Mature Human Milk- CHO • Lactose – Dominant carbohydrate in human milk. –
Enhances calcium absorption. • Other carbohydrates – Monosaccharides ( glucose) –
Stimulate the growth of bifidus bacteria in the gut • Inhibit the growth of E. coli and other
bacteria
28. 28. Micronutrients • Vary in human milk according to maternal diet and body stores. •
Continuing multivitamins during lactation is recommended. • Vitamin K is extremely low in
human milk. • Vitamin D is low in human milk.
29. 29. Bioactive components and their sources • CELLS macrophages: protection against
infection stem cells : regeneration and repair • Immunoglobulins : IgA, IgM,IgG • Cytokines
:IL-6,IL-7,IL-8 ,IL-10, IFN-y , TGF-beta • Chemokines : G-CSF, MIF
30. 30. BIOACTIVE COMPONENTS • GROWTH FACTORS- EGF, VEGF, NGF, IGF,
Erythropoetin • HORMONES- calcitonin,somatostain • Antimicrobials –lactoferrin,lactadherin/
MFG • METABOLIC HORMONES- Adiponectin, leptin, ghrelin

3. 31. 31. Why NO to top feed????? Mother’s Milk • Wide range of composition • Dynamic • Varies
with in a feeding • Diurnal variation FORMULA FEED • Narrow range • fixed
32. 32. Why no to top feed????? • Formula feeding delays lactogenesis • Formula feeding
increases the risk of engorgement . • It alters infant intestinal flora • Formula feeding affects
bioactive factor interactions within the intestine • Formula feeding is associated with
increased childhood acute and chronic illnesses
33. 33. WHAT STUDIES SAY A study by Davis, California found that after 4 months postpartum,
the macronutrient concentrations of human milk are associated with: • maternal body weight
for height • Protein intake • Parity • Return of menstruation • Nursing frequency . Nommsen

34. 34. What studies say • Some evidence that Erythropoetin may help protect against mother to
child transmission of HIV • Erythropoetin may reduce the risk of necrotizing colitis. • One
