Breastfeeding Protects Your Baby

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 prematurely.

Breast milk fights disease; the cells, hormones and antibodies in breast milk protect babies from illness. This protection is unique because formula cannot match the chemical makeup of human breast milk. Among formula-fed babies, ear infections and diarrhea are more common. Formula-fed babies also have higher risk of lower respiratory infections, asthma, obesity and type 2 diabetes.

Babies who are not breastfed are sick more often and have more doctor 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.

Benefits for Mom

Nursing uses up extra calories, making it easier to lose "baby weight". It also helps the uterus to revert to its original size and lessens any bleeding a woman may have after giving birth.

Breastfeeding, especially exclusive breastfeeding (no supplementing with formula), delays the return of normal ovulation and menstrual birth control choices.

Breastfeeding makes your life easier. It saves time and money. You do not have to purchase, measure, and mix formula. There are no bottles to warm in the middle of the night!

A mother can give her baby immediate satisfaction by providing her breast milk when her baby is hungry.

Breastfeeding requires a mother to take some quiet relaxed time for herself and her baby.

Breastfeeding can help a mother to bond with her baby. Physical contact is important to newborns and can help them feel more secure, warm and comforted.

Breastfeeding can be good for mom's health, too. Mothers who breastfeed their babies have a lower risk of developing postpartum depression, type 2 diabetes, breast and ovarian cancer, and possibly of hip fractures and osteoporosis after menopause.
