This guest post by Erica Johnson from Inner Parents highlights five facts about breastfeeding that are sure to encourage any lactating mother that she’s doing what’s best for her baby.
The breastfeeding relationship can provide a wonderful bonding experience between a mother and her infant. Nursing is also deeply comforting to most babies, helping them relax and drift off to sleep. The benefits of breastfeeding are not just emotional, however. Breast milk is a complex and dynamic substance that science is only beginning to understand.
Here are five facts about breastfeeding that prove what a truly unbelievable feat a woman’s body is capable of producing.

1. Breastmilk Contains Substances That Cannot be Recreated in Formula
Hormones, living immune cells and enzymes are exclusively supplied by breastmilk and are perfectly suited to each individual infant’s needs. Human milk contains several different types of proteins in concentrations and forms that are easily digestible. While minerals like calcium and iron are present to a lesser degree in breastmilk than in formula, they are in such readily available forms that the baby ends up absorbing a greater amount. The immune properties in human milk also bring the benefit of easier storage and less worry compared to formula.

2. Breastmilk Boosts Baby’s Immune System
Breastmilk is filled with a wide array of immune factors that help protect babies from viruses and bacteria. The specific antibodies the mother supplies provide tailored protection against microorganisms commonly found in the environment the baby is entering. The transfer of antibodies continues even once weaning has started: As baby begins to eat more solid food and less milk, the concentration of immune factors in the breastmilk increases.
3. Milk Composition Fluctuates Continually
Babies often can’t help falling asleep while nursing, but it is not just the act of nursing that encourages sleep. Studies of breastmilk samples have shown that certain sleep-inducing components are present in greater amounts during the evening and nighttime hours. The milk’s make-up changes even over the course of a single feed. At the beginning of a nursing session, the milk is high in lactose, low in fat and perfect for quenching baby’s thirst. Closer to the end, the lactose level decreases and the fat level rises, giving the baby a kind of “dessert” that keeps them full and satisfied until the next feeding.

4. Breastfeeding Burns More Calories Than Pregnancy
During the third trimester, approximately 300 more calories are required daily to support the growing baby. While breastfeeding, the mother will need 500 extra calories to produce breastmilk. Breastfeeding mothers often find it easier to lose the pregnancy weight, and nursing also helps the uterus return to pre-pregnancy size by stimulating stronger and more effective uterine contractions.
5. Breastfeeding Reduces Cancer Risk
Women who breastfeed their babies have been shown to have a lower risk of developing breast cancer later in their lives. Scientists believe this protection stems from the fact that estrogen levels are lower while breastfeeding continues. In addition, breastfed babies have lower rates of obesity throughout their lives. Since obesity is a significant factor in several types of cancer, the baby also is placed at a lowered risk of cancer in their own lives.
What do you think of these facts about breastfeeding? Did any of them surprise you? While breastfeeding has some incredible benefits for both mom and baby, it’s important to consider your own mental health as well. Breastfeeding may not always come easily for all moms and babies. There is a lot of help available, including online breastfeeding courses and in home lactation consultants.
