Objective: To elucidate the impact of inadequate breastfeeding on child development, addressing its short and longterm repercussions, in addition to highlighting the crucial benefits of exclusive breastfeeding in the first 6 months of life. Method: We used available scientific evidence, focusing on the PubMed database, through the search strategy "Breastfeeding", "Neurodevelopment", associated with the Boolean operator "AND". Initially, we identified 96 articles, 11 of which were selected as official sources to support the review. Discussion: Studies highlight the relevance of breastfeeding in the neurological development of infants, and is also a protective factor against chronic diseases due to its components. In summary, the review highlights relevant clinical implications that can be mitigated through breastfeeding, promoting the integrity of neurological health and the well-being of infants. Conclusion: The clinical implications discussed highlight the need to encourage and support this practice, aiming for the full neurological development and global well-being of infants.
