During the course of an experimental study of self-selection of diet by newly weaned infants1 carried on for several years in a nursery organized for this purpose the question of whether a new-born child could successfully exercise a choice of formula and regulate the quantities taken at feedings naturally suggested itself. This report outlines the experiment (also carried on in this nursery) designed to investigate that question and presents the results obtained during 1930 and 1931 with three breast-fed infants taken from lying-in hospitals at the ages of 10, 8 and 7 days, respectively, and subjected continuously to the experiment for periods of from seven and one-half to eight months.
Since there were obvious difficulties involved in presenting to such young infants a large number of formulas for choice at each feeding, it was decided to use for the experiment only four formulas which would be more or less
