When explaining the difference between cow's milk and breast milk, what key difference should the nurse highlight about cow's milk?

The key difference to highlight about cow's milk compared to breast milk is its higher protein and calcium content. Cow's milk contains significantly more protein, which can be difficult for infants to digest and may place an unnecessary strain on their immature kidneys. The higher calcium content in cow's milk can also pose a risk of hypercalcemia in infants when consumed in excess.

Breast milk, on the other hand, is specifically tailored for an infant's nutritional needs. It provides a balanced ratio of nutrients that are easier for an infant to digest, along with the right amount of protein to support growth without overwhelming the kidneys. Additionally, breast milk has immunological properties that are not present in cow's milk, which supports the infant's developing immune system.

Recognizing these differences is crucial for healthcare providers when educating parents and ensuring infants receive the best nutritional support during the early stages of life.
