Introduction:
With increasing survival rates of preterm infants, reducing morbidity and improving long-term prognosis have become a priority. Therefore, feeding is of utmost importance for the health and development of neonates in the Neonatal Intensive Care Unit. The aim of this literature review was to analyze the stages of transition from tube feeding to oral feeding and breastfeeding in preterm neonates in the Neonatal Intensive Care Unit.

Material and Methods:
Data were collected through literature review from databases (Medline/PubMed, Google Scholar and Crossref).

Results:
Based on data collected internationally, some techniques are based on the specificity of each population and require adaptation to the data of each Neonatal Intensive Care Unit.

Conclusions:
In any case, the correct implementation of the protocols by all NICU health professionals aims at the correct nutritional transition and establishment of oral nutrition, including breastfeeding.
