Which of the following is NOT a benefit of breastfeeding?

The correct answer highlights that early walking is not a benefit of breastfeeding. While breastfeeding provides numerous advantages for infants, such as antibodies that enhance immune function, cost savings compared to formula feeding, and support for brain development, it does not have a direct influence on the timing of physical milestones like walking.

Infants generally begin to walk around the same developmental age regardless of whether they are breastfed or formula-fed. Factors that influence walking include genetic predispositions and physical development rather than the method of feeding. In contrast, breastfeeding is known to aid in several ways: it boosts babies' immunity through antibodies, reduces costs associated with purchasing formula, and contributes positively to cognitive development and overall brain function, making those aspects significant benefits of breastfeeding.
