gher phosphorus content of cow's milk is linked to a decreased calcium level in the formula fed infant's blood. Breast fed babies are far less likely to become ill during the first year than formula fed babies. " The transfer of immune factors in breast milk and in the pre-milk substance, colostrum, provides partial protection. Every time breast fed infants suckle at their mother's breast from the first time to the last; they are getting a healthy dose of anti-bodies to bolster their immunity to disease" (Eisenburg 54). One recent study suggest " there may also be a decreased risk of childhood cancer in breast fed babies" (Eisenburg 55 ).Breast fed babies are well-nourished since breast feeding works by supply and demand. The more the baby nurses the greater the mother's milk production. Overall, babies that are breast fed have less health problems than babies that are artificially fed. "They have three times fewer ear infections, five times fewer urinary tract infections, five times fewer serious illnesses and seven times fewer allergies. Babies who are fed mother's milk exclusively, for at least their first twenty-six weeks, are six times less likely to develop lymphoma (a type of cancer) in childhood, and babies breast fed for at least one year are only half as likely to develop diabetes" (Sears 41).Breast milk can begin a lifetime of good health for a baby. As adults, people who were breast fed have: less asthma, diabetes, fewer skin disorders, fewer allergies, lowered risk of heart attack due to lower cholesterol levels, fewer ulcers, less Crohn's disease, and protection from certain chronic liver diseases. Breast milk encourages proper development. It promotes "good jaw development", which has an advantage to proper tooth development and alignment, and "active use of mouth and tongue while breast-feeding encourages proper speech development. Switching baby from right to left arm while feeding promotes balanced eye muscle...
