Final answer:
Cow's milk should be avoided for infants in their early stages of life due to its composition and difficult-to-digest proteins. It is recommended for infants to exclusively consume breast milk or formula for the first six months of their life.
Step-by-step explanation:
Cow's milk should be avoided for infants in their early stages of life. It is not suitable for their immature digestive system to metabolize and absorb due to its composition and difficult-to-digest proteins.
Cow's milk contains less lactose and fat but more protein and minerals compared to breast milk.
It is recommended for infants to exclusively consume breast milk or formula for the first six months of their life.
