Answer: D - Cow’s milk is unsuitable for infants less than a year of age due to its high renal solute load, which stresses the infant’s kidneys. Cow’s milk contains casein protein, which is less digestible than whey, and its percentages of fat and cholesterol are not significantly different from that of breast milk. According to the CDC, giving a child cow's milk before he or she is 12 months old, may put him or her at risk for intestinal bleeding. Cow's milk also has too many proteins and minerals for a baby's kidneys to handle and does not have the right nutrient mix.
