Background: The consequences of breastfeeding during pregnancy (BDP) have not been clearly established. Available studies have addressed isolated aspects of this issue using different methodologies, often resulting in contradictory results. To our knowledge, no systematic review has assessed and compared these studies, making it difficult to obtain a clear picture of the consequences of BDP.
Aim: To review and summarise all the scientific evidence relating to BDP, and determine whether this evidence is sufficient to establish clear implications for the mother, breastmilk, breastfed child, current pregnancy, and ultimately, the newborn.
