The primary benefit of breast milk is nutritional. Mother milk contains just the right amount of fatty acids, lactose, water, and amino acids for human digestion, brain development, and growth.

Cow's milk contains a different type of protein than breast milk. This is good for calves, but babies can have difficulty digesting it. Bottle-fed babies tend to be fatter than breast-fed infants, but not necessarily healthier.

Breast-fed babies have fewer illnesses because mother milk transfers to the baby a mother's antibodies to disease. Mothers produce antibodies to whatever disease is present in their environment, making their milk custom-designed to fight the diseases their babies are exposed to as well.

A breast-fed baby's digestive tract contains large amounts of beneficial bacteria that prevent the growth of harmful organisms. Mother milk straight from the breast is always sterile, never contaminated by polluted water or dirty bottles, which can also lead to diarrhea in the infant. Mother milk contains at least 100 ingredients not found in formula.

No babies are allergic to their mother's milk, although they may have a reaction to something the mother eats. If she eliminates it from her diet, the problem resolves itself.

Sucking at the breast promotes good jaw development. Its harder work to get milk out of a breast than a bottle, and the exercise strengthens the jaws and encourages the growth of straight, healthy teeth.

The baby at the breast can control the flow of milk by sucking and stopping. With a bottle, the baby must constantly suck or react to the pressure of the nipple placed in the mouth.
