The nutritional advantages of breast milk are certainly numerous. The amino acids in breast milk, the building blocks of proteins, are well balanced for the human baby, as are the sugars (primarily lactose) and fats. The baby's intestinal tract is best aided in its digestion by the vitamins, enzymes, and minerals found in breast milk. Breast milk also contains infection-fighting antibodies from the mother, and breastfed babies are believed to be at a reduced risk for many acute and chronic infections early in life. The cholesterol content is also high in human milk and very low in formulas. Cholesterol promotes brain growth and provides the building blocks of hormones, vitamin D, and intestinal bile.
Breast milk is also the least expensive way to feed an infant. However, the mother must maintain good nutrition and continue taking any vitamin/mineral supplements her doctor recommended during the pregnancy.
Formula-fed babies also have the risk of developing an allergy to a particular formula. When a baby develops an allergy to formula, he or she may have symptoms that include irritability, crying after feedings, nausea, vomiting, diarrhea, or a skin rash.
Nursing helps most women lose weight (though not fluid) after delivery, as 500 calories or more are used by breastfeeding each day.
There is a well-accepted extra closeness that breastfeeding mothers experience that is both hormonal and emotional in nature.
The only disadvantages for the baby in breastfeeding occur when things are not going well, for example, if there's an inadequate supply of breast milk or an inefficient suck reflex in the baby. However, it is unusual for a mother not to produce enough milk for her baby unless she is not breastfeeding correctly or frequently enough. The disadvantages that most commonly arise involve the rest of the family. Siblings and dad often feel "left out" of baby care since mom is the only one who can do the nursing. However, other family members can be involved in helping with different aspects of the baby's care, and this gives them a valuable feeling of importance and allows mom a chance to rest.
Breastfed babies eat more often than formula-fed babies since breast milk is more quickly digested and leaves the stomach empty more frequently. This puts a little more stress on the mother because of the potential necessity for more frequent feedings. If the mother develops certain medical conditions, whether or not to continue breastfeeding may need to be reassessed. These conditions should always be discussed with the doctor. However, it is rare that breastfeeding would need to be discontinued completely. In any interaction, the mother's doctor and/or pharmacist should be informed that she is breastfeeding. Some medicines should be avoided during breastfeeding. Numerous other medications have not yet been adequately studied in the context of breastfeeding and the possible effects on the baby. If a breastfeeding mother is required to take a medication which has not been fully studied, she may want to consider discussing this matter with her doctor.
