INFANT AND YOUNG CHILD FEEDING
LEARNING OBJECTIVES
• Enumerate components of Optimal Feeding
• Define Exclusive BF/Predominantly BF/ Replacement Feed/Mixed Feeding
• Describe process of Breast Feeding
1
LEARNING OBJECTIVES
• List advantages of breast milk and breast feeding
• Enumerate dangers of artificial feeding
2
Infant feeding
• Feeding the fetus –
Feeding the pregnant mother
• Feeding the infant 0-6 months- Exclusive breast feeding
• Feeding beyond 6 months-
Complementary feeding +BF
3
What is Optimal Infant and What is Optimal Infant and Young Child Feeding?Young Child Feeding?
• Optimal feeding is defined as exclusive breastfeeding from birth to six months of age and there after continued breastfeeding for 2 years or beyond
with adequate and safe complementary feeds to meet nutritional needs of a young child
4
Definitions for Infant FeedingDefinitions for Infant Feeding
Exclusive breastfed
Predominantly breastfed
Only breastmilk is given . No other food or drink,Not even water is given
The main source of nutrition is breastmilk but the child is also receiving other fluids (non-nutritive) or water
5
Definitions for Infant FeedingDefinitions for Infant Feeding
• Mixed feeding – the child receives animal milk, formula or cereal based foods in addition to breast milk
• Replacement feeding
Is the process of feeding a child who is not receiving any breast milk – with a diet that provides all the nutrients the child
needs until the child is fully fed on family foods

How Milk is Produced
• First few days after delivery- the breast feel soft and empty- only small amount of yellowish first milk (colostrum) is secreted
• After few days (may vary from 2 days to one week)-the breast begins to feel full , and sometimes hard- Milk has “come in”

Feeding ReflexesFeeding ReflexesRooting reflex
When somethingtouches lips,baby opens mouthputs tongue downand forward
Sucking reflex
When something touches palate baby sucks
Swallowing reflex
When mouth fills with milk,baby swallows
SkillMother learns to position babyBaby learns to take breast
Gag reflex
When something touches anterior part of the tongue, baby pushes it out.
13
Formation of Teat
• For effective suckling the baby does not take just the nipple but a mouthful of the areola and the breast tissue beneath, which contains the lactiferous sinuses
14
Mechanism of Mechanism of ‘Suckling Cycle’‘Suckling Cycle’
15
Remember
o Baby needs mother’s help initially to take the breast into his mouth
o Keeping baby and mother together makes breastfeeding successful
o More suckling makes more milk
o For sustained milk secretion, it is essential to breastfeed frequently
16
Advantages of BreastfeedingAdvantages of Breastfeeding to infant to infant
Breastmilk Perfect nutrients
Easily digestible
Ready to serve
Protects against
infection
Protects against
adult onset diseases
Breastfeeding Helps bonding and
development
Helps in adequate
growth and
development
Enhances brain &
visual development
Prevents hypothermia

Nutrients in Human & Animal MilkNutrients in Human & Animal MilkWhat are the differences between these milks?

Lower protein content puts lower solute load on kidney18
Differences in the Quality of Differences in the Quality of the Proteins in Different Milksthe Proteins in Different Milks
Anti-Infective Proteins
35% Casein
19
Proteins in human milk
Higher proportion of lactalbumin and lactoglobulin in breast milk form finer curds and are easily digested
Human milk proteins have a suitable quality of anti-infective protein
Contains taurine and cysteine necessary for brain development

Differences in the FatsDifferences in the Fats
HUMAN COW`S
Essential Fatty Acids,
PUFA
Enzyme Lipase
No Essential Fatty Acids
No Enzyme Lipase
21
Fats in human milk
• Higher content of PUFA promotes brain growth and protects against atherosclrosis
• Active lipase promotes fat digestion
• Contains Omega 2 and omega 6 (VLCFA)
• Facilitates absorption of calcium
22
Minerals
• Ca/P (2:1) ratio promotes Ca absorption
• High water content, Low Na+, low osmolality → low solute load to kidneys
• Adequate Zn

Breastmilk composition
• Colostrum • milk secreted during the first three days
after delivery• Yellow in color & thick• Rich in antibodies, vitamin A, D,E,K
• Transitional Milk• Milk secreted during the first two weeks • Immunoglobulin and protein contents
gradually decreases and the fat & sugar contents increases

Advantages of Breastfeeding Advantages of Breastfeeding to motherto mother
Reduces post delivery bleeding
and anemia
Delays next pregnancy
Protects breast and ovarian cancer
Prevent obesity
Convenient
29
Other Advantages
Society Eco-friendly
Human resource
development
Family Low cost involved
Less illnesses
Family bonding

Anti-infective properties
secretory IgA, IgM, Lysozymes
• Antistaphylococcal factor
• Lactoferrin less saturated with iron and prevents growth of enterobacteria
Bifidus factor protects from infection with E.coli
PABA protects from malaria
31
Disadvantages of Artificial Disadvantages of Artificial FeedingFeeding
More diarrhoea, ARI
and other infections
Requires preparation
Not easy to digest
Lacks balance of
nutrients
More likely to die
from infection &
malnutrition
Interferes with bonding
More allergy and
milk intolerance
Increased risk of some
chronic diseases
Overweight babies
May become
pregnant sooner
Increased risk of anemia,
osteoporosis, ovarian and breast
cancer

KEY MESSAGES
• EXCLUSIVE BREAST FEEDING is complete food and fluids for the baby till 6 months of age
• It prevents malnutrition and infants death
• Artificial feeding & bottle feeding are harmful to the baby, family and society.
