Breastfeeding protects your baby from gastrointestinal trouble, respiratory problems, and ear infections
Numerous studies from around the world have shown that diarrhea, lower respiratory illnesses, and ear infections happen less often in breastfed babies, and are less severe when they do occur. Exclusive breastfeeding (meaning no solid food) for at least six months seems to offer the most protection.
Researchers have found that immune factors that are present in colostrum (the first milk your body produces) guard against invading germs by forming a protective layer on your baby's mucous membranes in his intestines, nose, and throat. The main immune factor at work here is secretory IgA (immunoglobulin A). It's present in large amounts in colostrum — which is why it's important to start nursing your baby right after birth — but is also found in lower concentrations in mature milk.
Breastfeeding may also protect your baby from developing inflammatory bowel disease later in life. Several studies have documented a link between a lack of breastfeeding in infancy and later development of Crohn's disease and ulcerative colitis.
