Whole undiluted lactic acid milk, enriched with commercial corn syrup, was originally introduced as a satisfactory food mixture for athreptic infants.1A further experience, however, has led to the conclusion that such formulas are excellently adapted to the routine feeding of normal infants.2The type of feeding described does not lead to gastro-intestinal disturbances, even in young and undernourished infants. The composition of the formula does not have to be changed during a large part of the first year, the infant merely being offered increasingly larger amounts of the same food mixture as he becomes older. The caloric value is high (from 25 to 30 calories an ounce), and because of this fact a smaller number of feedings during the day is necessary, and malnutrition due to underfeeding does not occur.
