The longitudinal changes on human milk intake of exclusively breast-fed infants(boys=15, girls=12) from 0.5 to 6 months after parturition have been studied by test-weighing method in Cheongju and Anseong area. Infant milk intake per day tended to increase during lactation. The mean intake at 0.5, 1, 2, 3, 4, 5, and 6 months were 532, 695, 734, 756, 785, 767, and 710g, respectively. The average intakes were 752 and 660g for boys and girls, respectively. The overall mean intake was 711g/day. The milk intake between boys and girls at 1, 2, 4 months, and mean value was significantly different(p<0.05). Infant milk intake had a significant positive correlation with human milk volume of lactating women, but no correlation with maternal age, weight before delivery, height, and birth weight.
