[An update on infant nutrition].

Present practices concerning childhood feeding are dynamic. During the first four to six months of life breast feeding proportionates all the necessary nourishment. If breast feeding is not possible, we can give milk formulas by baby bottle; during the first four months with "starting" formulas, and later with "follow up" formulas. The American Academy of Pediatrics does not recommend to give whole cow's milk during the first year of life. Since the physiological and neurological development approach, we can begin the introduction of solid foods between four and six months old, in a systemic form and offering foods with a nutritional content, texture, coloration and taste varied and appropriated for the baby's age, to achieve the primary objective in childhood feeding, that consists in provide enough calories and nourishment to promote the optimal growth and development.
