Today, despite the benefits reported in all studies, the incidence and duration of the use of maternal milk by preterm babies are usually lower than recommended. Among other factors, the lack of maternal milk use in the diet offered to these babies during hospitalization favors weaning. Common reasons for the lack of use of human milk is the anxiety of the health team regarding the rate of weight gain, although the use of an infant formula in the present study did not show nutritional advantages compared to maternal milk at the time of discharge. Another reason is the long time between birth and the transition to oral feeding, with the need for much stimulation and involvement of the health team to maintain lactation during the period of hospitalization of premature babies (29,30).
