Breastfeeding support and counseling

Physiology of Lactation - The Milky Way

• Lactogenesis (Production): Driven by Prolactin (Anterior Pituitary). Suckling ↑ levels.
• Galactokinesis (Ejection): Mediated by Oxytocin (Posterior Pituitary) → myoepithelial cell contraction (let-down reflex).
• Galactopoiesis (Maintenance): Regular suckling is crucial to maintain production by stimulating prolactin and oxytocin release.
• Autocrine Control: Feedback Inhibitor of Lactation (FIL) in whey protein; milk stasis → ↑FIL → ↓ production.

⭐ Progesterone withdrawal after placental delivery removes its inhibitory effect on prolactin, initiating copious milk secretion (Lactogenesis Stage II) within 48-72 hours.

Breast Milk Composition - Nature's Liquid Gold

• Types of Milk

  • Colostrum (First 3-4 days): Low volume, high density. Rich in secretory IgA, lactoferrin, Vitamin A, leukocytes.
  • Transitional Milk (Day 5-14): Gradual change; ↑ fat & lactose.
  • Mature Milk (After 14 days): Separated into:
    • Foremilk: Watery, high lactose; quenches thirst.
    • Hindmilk: Opaque, high fat; provides energy & satiety.

• Key Components vs. Cow's Milk

  • Energy: 65-70 kcal/dL.
  • Proteins (0.9 g/dL): Whey dominant. Whey:Casein ratio is 60:40.
  • Fats (3.5 g/dL): Rich in LCPUFAs (DHA, ARA) for neurodevelopment.
  • Carbohydrates (7 g/dL): Primarily Lactose. Oligosaccharides act as prebiotics.

⭐ Human milk's Whey:Casein ratio is 60:40, promoting easy digestion. Cow's milk is reversed at 20:80, forming a harder curd.

Breastfeeding Technique - The Perfect Latch

Signs of a Good Latch (Attachment):

• Mouth wide open
• Lower lip flanged outwards
• Chin touching the breast
• More areola visible above the baby's mouth than below

Effective Suckling Indicators:

• Slow, deep sucks with occasional pauses
• Audible swallowing sounds
• Cheeks are full and rounded, not drawn in
• Mother feels a drawing/tugging sensation, not pain
• Baby releases the breast spontaneously after a feed

⭐ Exam Favourite: Pain is a sign of a poor latch. The baby should take a large mouthful of breast tissue, not just the nipple, to prevent nipple soreness and ensure adequate milk transfer.

Common Breastfeeding Problems - Nipple 911

• Sore/Cracked Nipples: Most common cause is poor latching.

  • Management: Correct positioning & latch. Apply expressed breast milk (EBM) or purified lanolin. Air-dry nipples.

• Nipple Vasospasm (Raynaud's): Intermittent ischemia from cold/latch issues.

  • Symptoms: Triphasic color change (white → blue → red/purple) with severe, throbbing pain.
  • Management: Warm compresses. Avoid cold exposure. Nifedipine may be prescribed.

• Inverted/Flat Nipples: Assessed with the 'pinch test'; nipple retracts or doesn't protrude.

  • Management: Hoffman's maneuver, modified syringe suction before feeds, nipple shields.

• Candida Infection: Burning, stinging pain; nipples may be pink, shiny, or flaky.

  • Management: Topical miconazole/clotrimazole for mother & oral nystatin for baby (if thrush present).

⭐ Most common cause of nipple pain in the first week of breastfeeding is improper infant positioning and latch.

• Absolute contraindications to breastfeeding include galactosemia in the infant, and active untreated TB or HIV (in developed nations) in the mother.
• Prolactin from the anterior pituitary governs milk synthesis; oxytocin from the posterior pituitary controls the milk ejection reflex.
• The LATCH score is a standardized tool for assessing breastfeeding technique immediately postpartum.
• Breast engorgement involves bilateral, diffuse swelling, whereas mastitis is typically unilateral, focal, and associated with fever.
• Breastfeeding significantly reduces infant risk of otitis media, gastroenteritis, and necrotizing enterocolitis.
• For the mother, lactation lowers the risk of breast and ovarian cancer.
