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 FeedingExclusive 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 milko 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

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

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

Vitamins in Different MilksVitamins in Different Milks

24

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 ColostrumAdvantages of Colostrum

Property Antibody rich

Many white cells Purgative effect

Growth factors

Vitamin A rich

Importance protects against infection and

allergy protect against infection clears meconium helps to

prevent jaundice help intestine to mature

prevents allergy, intolerance reduces severity of infection

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

Other Advantages

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

Breastfeeding is defined as exclusive breastfeeding for first 6 months and continued breastfeeding during 6-11 months

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.
