Which of the following is a benefit of breastfeeding for infants?

Breastfeeding is known to significantly contribute to enhanced cognitive development in infants. The milk produced by breastfeeding mothers contains vital nutrients such as omega-3 fatty acids, which are crucial for brain development. Studies have shown that children who were breastfed tend to perform better in cognitive assessments as they grow older, often showing higher IQ scores and better academic performance. This cognitive advantage is attributed to the ideal composition of nutrients in breast milk that supports brain growth and function during the critical early months and years of life.

In contrast, the other options present potential misconceptions regarding breastfeeding. For example, risks of dehydration and stomach issues may be more prevalent in formula-fed infants or in situations where breastfeeding is not adequately supported, but they are not a direct benefit of breastfeeding. Breastfeeding, in fact, typically promotes better hydration through the appropriate balance of fluids. Additionally, the immune system of breastfed infants tends to be stronger due to the presence of maternal antibodies in breast milk, which provides protection against infection and contributes positively to an infant's overall health.
