Health Impact of Not Breastfeeding
Formula-feeding vs. breast-feeding: risk of adverse outcomes.
Breastfeeding and Maternal and Infant Health Outcomes inDeveloped Countries. AHRQ Evidence Report Number 153. April 2007.
- Exclusive breastfeeding for the first six months of life
- Continued breastfeeding for at least one year, ‘As long as is mutually desired by mother and child’
American Academy of Pediatrics (2005). "Breastfeeding and the Use of Human Milk." Pediatrics 115(2): 496-506.
- HTLV-1 and HTLV-2
- HSV with lesion on the breast
- Active tuberculosis
- Medications that contraindicate breastfeeding
- Newborn with galactosemia
- Maternal HIV
- US: not recommended
- UNICEF: When replacement feeding is acceptable, feasible, affordable, sustainable and safe, avoidance of all breastfeeding is recommended; otherwise, exclusive breastfeeding is recommended during the first months of life.
How Does Lactation Happen?
Where does milk come from?
Let Down: Ejection, not suction, moves milk to the areola.
- Moves milk from lobules to sinuses, so baby can eat
- Inhibited by stress, pain, anxiety
- Triggered by sound, smell, sight of infant
Stress and Milk Volume
J. Pediatr 1948; 33:698-704.
Latch: The baby’s tongue moves milk from areola to nipple.
- Infant grasps most of the areola in his mouth
- Tongue “milks” milk to the back of the mouth prior to swallowing.
Moving Milk:Demand drives supply.
- Milk in lobules contains whey protein called Feedback Inhibitor of Lactation (FIL)
- If milk is not removed, and lumen is full, production will decrease
- Goal: 10-12 feeds in 24 hours, until baby is done.
Start out right: establish normal physiology
Evidence-based early care
Low Milk Supply
- Primary lactation failure
- Anatomic abnormality
- Sheehan’s syndrome
- Disruption of normal physiology
- Infrequent or inadequate milk removal
- Postpartum depression
- First line therapy:
- Lactation consultation
- Mechanical expression after breastfeeding
- If needed:
- Supplement after breastfeeding as indicated
- Continue pumping during supplementation
- Consider metoclopramide
- Definition: tender, swollen, wedge-shaped area of breast, usually unilateral, with fever, malaise, chills, and systemic symptoms
- Incidence: 3 to 20%
- Rest, fluids
- Antibiotics – Dicloxicllin 500mg QID x 10-14d
- Empty the breast
- Evaluate latch
- Continue frequent breast feeding
- Milk is not harmful to healthy, term infant
- Abrupt weaning slows maternal recovery
- Poor response requires further evaluation
Academy of Breastfeeding Medicine. ABM Clinical Protocol #4: Mastitis. Breastfeeding Medicine 3(3); 2008.
- 3% of women with mastitis
- Hard, red, tender mass after appropriate treatment
- Diagnostic ultrasound
- Needle aspiration for culture / treatment
- Surgical drainage for large or multiple abscesses
- Follow-up care
- Continue breastfeeding
