Well i dont think there is hard evidence, but my dad was breastfed 4 to 5 months less than all 4 of his siblings, and has the most problems as an adult. (allergies, back, arthritis) just everything across the board. whether the 2 are related idk but, i'm just sayin.

i think so because breast milk has more nutrients in it and breastfeeding bonds the mother with the child

Happier :)

Mine was bottle fed with formula, and is healthy as can be. In 90th percentile in her height -- she's a monster.

Breast-fed babies have fewer illnesses because human milk transfers to the infant a mother's antibodies to disease. About 80 percent of the cells in breast milk are macrophages, cells that kill bacteria, fungi and viruses. Breast-fed babies are protected, in varying degrees, from a number of illnesses, including pneumonia, botulism, bronchitis, staphylococcal infections, influenza, ear infections, and German measles. Furthermore, 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 Lactobacillus bifidus, beneficial bacteria that prevent the growth of harmful organisms. Human 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. Nursing may have psychological benefits for the infant as well, creating an early attachment between mother and child. At birth, infants see only 12 to 15 inches, the distance between a nursing baby and its mother's face. Studies have found that infants as young as 1 week prefer the smell of their own mother's milk. When nursing pads soaked with breast milk are placed in their cribs, they turn their faces toward the one that smells familiar. Many psychologists believe the nursing baby enjoys a sense of security from the warmth and presence of the mother, especially when there's skin-to-skin contact during feeding. Parents of bottle-fed babies may be tempted to prop bottles in the baby's mouth, with no human contact during feeding. But a nursing mother must cuddle her infant closely many times during the day. Nursing becomes more than a way to feed a baby; it's a source of warmth and comfort. Breast milk is the most complete form of nutrition for infants. A mother's milk has just the right amount of fat, sugar, water, and protein that is needed for a baby's growth and development. Most babies find it easier to digest breast milk than they do formula. As a result, breastfed infants grow exactly the way they should. They tend to gain less unnecessary weight and to be leaner. This may result in being less overweight later in life. Premature babies do better when breastfed compared to premature babies who are fed formula. Breastfed babies score slightly higher on IQ tests, especially babies who were born pre-maturely. Breast milk has agents (called antibodies) in it to help protect infants from bacteria and viruses. Recent studies show that babies who are not exclusively breastfed for 6 months are more likely to develop a wide range of infectious diseases including ear infections, diarrhea, respiratory illnesses and have more hospitalizations. Also, infants who are not breastfed have a 21% higher postneonatal infant mortality rate in the U.S. Some studies suggest that infants who are not breastfed have higher rates of sudden infant death syndrome (SIDS) in the first year of life, and higher rates of type 1 and type 2 diabetes, lymphoma, leukemia, Hodgkin's disease, overweight and obesity, high cholesterol and asthma. More research in these areas is needed (American Academy of Pediatrics, 2005). Babies who are not breastfed are sick more often and have more doctor's visits. Also, when you breastfeed, there are no bottles and nipples to sterilize. Unlike human milk straight from the breast, infant formula has a chance of being contaminated.

In my experience, Yes.
