2. Which milk is most similar to mother’s milk?

Cow’s milk is believed to be nearer and most similar to mother's milk. Though it varies in the following way-

• Absence of Vitamin E, iron, or essential fatty acids can lead to anemia in infants fed on cow's milk.
• Presence of high amounts of protein, sodium and potassium may put a strain on the infants’ immature kidneys.
• It is difficult to digest and absorb protein and fat in whole cow's milk.
• Cow's milk also lacks the immune factors (antibodies) that help protect infants until their own immune system fully develops.
