The systematic weighing of infants at least once a week is a very useful indication of the progress in nutrition and growth which they are making, and it should not be neglected.

Budin reported some interesting experiments with three classes of infants - namely, (1) suckled, (2) partly suckled, partly artificially fed, (3) artificially fed. During the first fortnight of life he found that the gain in weight was considerably more rapid with suckled infants, but during the first year of life the infant will gain as much weight if fed upon cow's milk as if suckled. Roughly speaking, the infant's weight should be doubled in the first five months of life and trebled in the first year.
