Answer:
The young infants do not possess the tendency to digest whole milk as easily or completely as they digest formula milk. In addition, the whole milk comprises higher quantities of minerals and proteins that can stress the immature kidneys of newborns and can result in extreme illness at the times of fever, heat stress, or diarrhea.
The whole milk is also devoid of the proper concentrations of vitamin C, iron, and other nutrients, which are required by the infants. It may also result in iron-deficiency in some of the infants. It also does not contain the healthiest kinds of fat for developing babies. Due to this it is recommended to not provide whole milk for the initial twelve months of life.
