Background: Breastfeeding is universally recognized as the gold standard for infant nutrition, playing a crucial role in preventing Iron Deficiency Anaemia (IDA) which could affect the growth and development of newborns. Objectives: This review discusses how breastfeeding could help prevent iron deficiency early in life and may provide long-term benefits in reducing the incidence of anaemia. Methods: The research was designed as a literature review, examining several articles from three online databases: Google Scholar, PubMed, and ScienceDirect. Discussions: Breastfeeding provides essential nutrients, and breast milk helps lower the occasion of IDA in infants. Although the iron content in breast milk is low, it is easily absorbed due to a component called lactoferrin. Vitamin C in breast milk also helps most effectively to increase iron absorption. Providing iron-rich complementary foods can help meet the daily iron needs of infants and children. The percentage of mothers who do not practice exclusive breastfeeding remains high (69.3%). This is attributed to various factors, including awareness of breastfeeding's importance, economic challenges, and lack of support for exclusive breastfeeding. Conclusions: Exclusive breastfeeding may provide enough iron for infants for the first four to six months to avoid IDA. However, to keep preventing IDA after six months of age, supplemental foods that include iron are paramount. Support from various parties is essential to promoting and increasing exclusive breastfeeding. Further studies to explore the breastfeeding and IDA are essential for worldwide IDA prevention.
