Many problems relating to the premature baby have received intensive study during the past few decades. This has resulted in more efficient care of the premature with a subsequent decrease in the mortality rate. It is surprising, however, that there is still so much difference of opinion regarding the feeding of premature babies, not only with respect to the type of food but also to the timing of the first feed.Former authorities apparently favoured early feeding. For instance Goodhart (1913) wrote: 'these feeble infants must not be allowed to wait two or three days for regular feeding with the mother's milk; the loss of weight and possible rise of temperature which such waiting involves-may be the last straw for one of these infants, who is fighting a feeble struggle for existence'. Hess (1923) recommended that milk should be given to premature babies from 12 hours of age; he stated, 'the necessity of an early supply of food cannot be over-emphasized, as even the better developed infants do not withstand prolonged starvation'. During the past decade or so a number of writers have advised that feeds should be withheld from premature babies for periods of 12 to 96 hours depending upon the degree of immaturity at birth, mainly on the grounds that the premature is particularly liable to pneumonia due to the aspiration of vomit. Newborn premature infants frequently manifest oedema suggesting that they are overhydrated, and Smith (Smith, Yudkin, Young, Minkowski and Cushman, 1949;Hansen and Smith, 1953;Smith, 1957) Schofield (1950) were also strong protagonists of a three-tofour-day starvation period for premature infants.They thought the time of the first feeding should be determined by the strength of the cry and the disappearance of oedema. Crosse (1957) wrote about the possible dangers of overfeeding during the first week of life and considered that the survival rate of premature infants had been improved by giving nothing by mouth for several days after birth. She recommended starvation periods varying from 12 hours to four days depending upon the birth weight.Ylppo (1954)
