How long should a breast feed last?

P W Howie, M J Houston, A Cook

    Summary

    Breastfeeding duration varies greatly among mothers. Infant feeding cues, not fixed schedules, should determine how long a baby breastfeeds for optimal milk intake.

    Area of Science:

    • Lactation and Infant Nutrition
    • Maternal-Infant Health
    • Pediatrics

    Background:

    • Breastfeeding is crucial for infant nutrition and maternal health.
    • Established feeding schedules may not align with individual infant needs or milk transfer dynamics.
    • Understanding milk flow patterns is essential for effective breastfeeding support.

    Purpose of the Study:

    • To investigate milk flow patterns in breastfeeding mothers and infants.
    • To compare different feeding regimens and their impact on milk intake.
    • To determine factors influencing milk transfer and inform breastfeeding duration recommendations.

    Main Methods:

    • Progressive test weighing of 50 mothers and their infants on days 5-7 postpartum.
    • Measurement of milk intake at 5-minute intervals during two consecutive feeding sessions.

  • Comparison of feeding durations (e.g., 10x10 min vs. 5x5x5x5 min intervals).
  • Main Results:

    • Significant variation observed in feeding duration (mean 17.3 min), initial milk flow rate (mean 6 g/min), and total milk intake (mean 70.9 g).
    • Shorter, more frequent feeding intervals (5x5x5x5 min) increased early milk intake but did not affect overall intake or prolactin release.
    • Milk intake correlated with initial milk flow rate, but not feeding duration, infant birth weight, or time since last feed.
    • 75% of feeding episodes had nutritive feeding times of 15 minutes or less, indicating 20-minute recommendations are often inappropriate.

    Conclusions:

    • Breastfeeding duration should be guided by infant cues and milk transfer, not arbitrary time limits.
    • Individual variations in milk flow and intake necessitate personalized breastfeeding support.
    • Current recommendations for breastfeeding duration may not be optimal for many mother-infant dyads.
