Define Breastfeeding — Physiology, Advantages & Problems. Describe its types and management.

Definition

• Breastfeeding is the feeding of an infant with the mother's milk.
• Exclusive breastfeeding (only breast milk — no water or other food, except medicines/vitamins) is recommended for the first 6 months, with continued breastfeeding alongside complementary foods up to 2 years or beyond.

Physiology of Lactation — Hormones

• Prolactin (anterior pituitary) → the milk-secretion (production) reflex; surges with each suckling episode, more at night → 'the more the baby suckles, the more milk is made'.
• Oxytocin (posterior pituitary) → the 'let-down' / milk-ejection reflex, contracting myoepithelial cells; stimulated by suckling and by seeing/hearing the baby, but inhibited by pain, anxiety and stress.
• A local feedback inhibitor of lactation (FIL) in retained milk slows production — hence emptying the breast increases supply.

Infant Reflexes Involved

• Rooting reflex — turning to the stimulus and opening the mouth.
• Suckling reflex — rhythmic suckling when the nipple/areola touches the palate.
• Swallowing reflex — coordinated swallowing of milk.

Types / Stages of Milk

• Colostrum (days 1–4) — thick, yellow; rich in protein, vitamin A and secretory IgA; laxative (helps pass meconium). 'The baby's first immunisation'.
• Transitional milk (day 5–14) → mature milk thereafter.
• Foremilk (start of a feed) — watery, quenches thirst; hindmilk (end) — fat-rich, gives most calories & satiety.

Advantages

To the baby:

• Ideal, easily digested, balanced nutrition; promotes optimal growth & brain development (DHA).
• Anti-infective — IgA, lactoferrin, lysozyme, macrophages, bifidus factor → fewer diarrhoeal & respiratory infections.
• Reduces later obesity, type-1 diabetes, allergy & necrotising enterocolitis; always sterile and at the right temperature.

To the mother:

• Oxytocin promotes uterine involution & reduces postpartum haemorrhage.
• Lactational amenorrhoea gives natural birth spacing; reduces breast & ovarian cancer risk; aids weight loss and bonding.

To the family/society: economical, convenient, no preparation, and reduces child mortality & healthcare costs.

Contraindications

• Infant: galactosaemia (absolute); certain inborn errors of metabolism (special formula).
• Mother: untreated active TB (until non-infectious), active herpes lesion on the breast, cytotoxic/radioactive drugs, and maternal HIV (as per current national policy with ART).
• Most maternal illnesses and medications are not contraindications.

Correct Attachment & Positioning

• Signs of good attachment (calm): Chin touching breast, Areola more visible above than below, Lips flanged out, Mouth wide open.
• Baby well supported; head & body in a straight line, facing the breast, 'tummy-to-tummy'; the baby takes a large mouthful of areola, not just the nipple.

Expression & Storage of Breast Milk

• Milk can be expressed by hand or pump when the mother and baby are separated (work, prematurity, illness).
• Storage: room temperature ~6 hours, refrigerator ~24 hours; feed by cup (not bottle).

Common Problems & Management

Assessing Adequacy of Breast Milk

• Satisfactory weight gain along the growth chart — the most reliable sign.
• The baby passes urine ≥ 6 times a day (pale, dilute) and has soft stools.
• The baby is settled and satisfied after feeds and sleeps well between them.
• Audible swallowing during feeds; the breast softens after a feed.

Promotion

• Early initiation within 1 hour; rooming-in; no prelacteal feeds; avoid bottles/pacifiers.
• Support via the Baby Friendly Hospital Initiative (BFHI) and IYCF counselling; enforce the IMS Act.

Iycf Definitions (WHO)

• Exclusive breastfeeding — only breast milk (plus medicines/vitamins), nothing else, for 6 months.
• Predominant breastfeeding — breast milk + water/water-based drinks.
• Complementary feeding — breast milk + solid/semi-solid foods (from 6 months).
• Bottle feeding — feeding from a bottle (discouraged — infection & nipple-confusion risk).

Steps of Correct Technique

• Wash hands; sit comfortably and support the baby's whole body, turned towards the mother.
• Touch the baby's lips with the nipple to trigger rooting; wait for a wide-open mouth.
• Bring the baby to the breast (not the breast to the baby) so a large mouthful of areola is taken.
• Empty one breast fully (for hindmilk) before offering the other; burp the baby after the feed.

WHY Colostrum Must Never Be Discarded

• A practice that costs lives in India is understanding why colostrum — which many communities discard as 'dirty', 'stale' or 'insufficient' — is the most valuable feed the baby will ever receive.
• It is produced in small volume, and it looks thick and yellow — which is precisely why it is mistrusted, and why prelacteal feeds (honey, sugar water, ghutti, animal milk) are given instead.
• But that small volume is exactly matched to the newborn's tiny stomach, and it is extraordinarily concentrated: it is rich in secretory IgA and white cells, which coat the gut and provide the baby's first immune defence against the organisms they are about to meet; it is high in protein, and in vitamin A (protecting against infection and blindness); it is laxative, hastening the passage of meconium and thereby reducing jaundice; and it contains growth factors that mature the gut.
• In effect, it is the baby's first immunisation.
• Discarding it, and replacing it with prelacteal feeds, deprives the baby of this protection and simultaneously introduces infection and interferes with the establishment of lactation.
• Hence: breastfeed within one hour of birth, give colostrum, and give NO prelacteal feeds.
