title: Nutrition and development in infants of poor rural areas.  Pt. 1.  Consumption of mother's milk by infants.
abstract: This study was designed to examine the pattern of mother's milk consumption of infants from poor Mexican rural areas.  A standardized sample of 17 mother-infant units was longitudinally studied in ad-libitum conditions, estimating milk volume by difference in body weights before and after feeding from the breast.  Average total milk consumption during the 1st year of life was 183 +or- 23 liters.  Daily milk consumption started low (423 +or- 85 ml), increased to a peak at 450 +or- 80 ml, and finally dropped to about 350 +or- 44 ml at 18 months.  About 1/2 the cases reached the peak at 8 weeks and the rest at 24 weeks; this difference in presentation of the peak was connected to the mother's parity and nutritional status.  Consumption seems to depend on mother's production since the baby keeps a high demand as evidenced by high feeding frequencies and too long sucking times.  The gap resulting from decreasing milk production at a time when nutritional needs increase progressively affects the baby's development and nutritional status.
