Introduction. Currently, there are frequent cases of both underestimation of the importance of prescribing additional nutrition to a breastfed child by medical personnel, and unjustified introduction of infant formula, especially during the early neonatal period. The reason obviously lies in the lack of clear criteria for assessing the adequacy of lactation in a nursing mother and medical indications for the introduction of supplementary feeding in current recommendations. The aim of this publication was to analyze the existing literature on the presence of transient conditions in newborns over the early neonatal period associated with insufficient consumption of breast milk and to develop a methodology for their correction through the timely introduction of supplementary feeding with infant formula followed by its discontinuation.

Materials and methods. Implementation of the “Supplemental Feeding for Full-Term Breastfed Newborns” checklist at a perinatal center. Retrospective analysis of medical records.

Results. The introduction of a checklist into the perinatal center’s work, with the registration of the rationale for the introduction and withdrawal of supplementary feeding in medical records, allows, on the one hand, eliminating the unjustified prescription of supplementary feeding to newborns. On the other hand, to promptly identify infants who need of additional nutrition, select the optimal amount, monitor the condition of the newborn and the trend in his body weight and ensure the timely cancellation of supplementary feeding, which contributes to the creation of an effective model for supporting breastfeeding among newborns.

Conclusion. During the neonatal period, there are various conditions, that may require supplemental feeding in the newborn due to insufficient maternal milk. The developed checklist for the purpose of supplementary feeding is a modern technology for maintaining breastfeeding and an important practical step in supporting it from the first day of the life.
