What are infants fed in the United States?

Estimates of calorie intake from various sources during infancy are presented in relation to age. The estimates, based on published reports and personal communications to the author, concern total calorie intake and its distribution between milk or formula and beikost (i.e., foods other than milk or formula fed to infants), relative prevalence of breast, formula- and milk-feedings, relative popularity of specific commercially prepared formulas, and percentage of calories consumed in the form of commercially prepared strained and junior foods and "table" foods.
