Factors influencing lactation performance in rural Gambian mothers

Breast-milk consumption has been measured in a rural African community in which breast-feeding on demand is universally practised until the baby is 18 mos old. The mother's long-term capacity for breast-milk production is determined by the end of the second month of lactation, yield being closely correlated with the infant's birth-weight. Other factors significantly influencing output were parity, month of lactation, baby's weight-for-age, season, and maternal diet. Daily milk consumption was limited primarily by the amount delivered per feed, not the frequency of feeding.
