[Breast feeding under different nutritional and nursing conditions. Analysis of 644 newborn infants, 1979-1981].

The effects of different nutritional patterns and nursing conditions on the form of newborn feeding were retrospectively analysed. A comparison was made of 644 infants born between 1979 and 1981. Feeding in 1979 was based on a regime adapted from Kellner. Gradual increase in feeding in the first days of age was resumed as of 1980.--The percentage of breast-fed newborns was affected by feeding plans. Gradual increase of daily food supply caused increase in the number of breast-fed children. Close contact between mother and child, as in being enabled by the partial rooming-in system, was found to be the strongest stimulation for breast feeding.
