A better guideline on milk requirements for babies below 6 months.

The volume of infant formula required for babies below the age of 6 months continues to pose problems both for parents and child health care workers. To investigate this, about 150 bottle-fed babies were studied every 2 months from birth for their milk intake and weight gain. They were fed on demand with full strength infant formula and weaning was started at about 4 months. Weight gain was normal, with growth patterns comparable to Cambridge babies. The mean (s.d.) daily milk volumes in millilitres consumed were: 582 (144), 847 (163), 851 (176), 812 (219) at 7 days, 2, 4 and 6 months, respectively. With such a wide range of milk intake at each age, it would be inappropriate and misleading to provide a single mean recommended volume. Thus, percentile values are suggested as a better guideline for recommended intake. Estimation was made for the volume of milk required if milk was the sole source of energy for the first 6 months.
