What are the emotional benefits of breastfeeding?

You might already know about the physical benefits of breastfeeding, and how breastfeeding can save you some time and money. But if you’ve never breastfed before, you might not be familiar with the positive effects it can have on your mind, mood, and overall well-being. There are two hormones that are mainly responsible for how breastfeeding works: prolactin and oxytocin. Both of these hormones contribute to how breastfeeding positively impacts a mother’s mental state.

How prolactin and oxytocin help with breastfeeding

Prolactin, which increases during pregnancy and then stays at high levels if a woman is breastfeeding, stimulates breast tissue growth and breast milk production. Oxytocin, which is released when a baby suckles, signals to the breast to let-down milk. Oxytocin actually works a little bit like a reflex in that over time, it can be stimulated when a mother simply smells, hears, or even thinks about her newborn.

Emotional effects of prolactin and oxytocin

Prolactin and oxytocin aren’t just important because they make breastfeeding possible (which is pretty important by itself), but because they make breastfeeding an even more emotionally rewarding experience for women and their babies (and even new fathers). Prolactin has a calming effect on breastfeeding mothers, and it lowers libido in new parents. Oxytocin, also called the “love hormone” or the “bonding hormone”, strengthens the feelings of fondness and love between a mother and her newborn which helps new mothers feel bonded to their baby. Oxytocin can help fight feelings of sadness of depression, which may lower a woman’s risk of postpartum depression or the baby blues.

The bottom line

Those strong loving feelings that you get while you watch them breastfeed are enhanced in part due to the hormones produced by your body. The hormones and their effects help to strengthen the bond between you and Baby, while creating a relaxing, calming effect that makes breastfeeding more enjoyable experience for you and Baby. The hormones involved in breastfeeding may even have some protective mental health effects, making it less likely that a new mother will experience the baby blues or postpartum depression.
