Why One Breast Produces More Milk Than the Other: The Case of Stud vs. Dud.

Breastfeeding is an amazing experience that leads people all over the world to ask many questions. One of which is why one breast produces more milk than the other, or in other words why is one side a stud and the other a dud?

Could there be a correlation between the side your sweet baby first nurses on? 

Personally, the side I first nursed my daughter on is the side that produces the bulk of my milk. This got me wondering if there was a correlation between which side your baby first latched onto and how much milk that side produced. In an online survey, out of 34 moms, 24 of them saw a correlation between what side they first nursed on and what side was their “stud”, whereas 10 of them saw no correlation. That means 70% of the moms surveyed in this online forum also had the same experience with their bulk producer being their babies first latch.

This could be coincidental, and there are obviously a lot of other factors that take place. However, you could argue that this side got more stimulation at the ideal time.

Babies preferences might be determined from the get go.

Sometimes babies simply prefer one side over the other. Because of this, that one side gets more stimulation therefore demanding more from that breast. Breastfeeding works on a supply and demand system so the more your baby takes from one side the more it will produce. Other times, your baby might determine their preference due to a forceful let down or slow let down. She might dislike the forceful let down as it can cause stomach aches and gas, along with being hard to swallow. On the other hand, like my baby, she might not like the slow let down and having to work so hard for your liquid gold.

She might have an ear infection or strained muscle.

If your baby has an ear infection she might be in pain when laying on that side. This can cause your baby to not want to nurse on that side and decrease the milk supply of that breast. She may also have a strained muscle from delivery that causes discomfort. If you think your baby might have an ear infection or a strained muscle, contact your pediatrician immediately to get it addressed. Also, try different nursing positions to see if this helps.

Different sizes and anatomy of the breast.

Like everything else on the human body, women often have one breast that is larger than the other, sometimes one of them can have more milk glands causing it to have a higher supply. However, just because one side is smaller, doesn’t mean that it won’t produce as much milk as the larger one.

Increasing supply of the “dud”.

Although it is perfectly fine to have one side produce more milk than the other, there are many ways to increase the supply on that side. Some of which include:

• Adding an extra pumping session to that side and pumping after each feed.

• Starting each nursing session with the less productive side, switch to the more productive side and then finish with the one you started with.

• Try to nurse on the side that produces less milk more often.

• Drink a lot of water!!!! And eat a nutritious diet:)

• Massage and compress the breast.

• Use heat to increase blood flow to that side.

Lansinoh has a great product that helps with let down and with engorgement. You can purchase these almost anywhere, Wal-Mart for about $13 or Amazon just to name a few of locations.

Do you have one breast that produces more than the other? Have you noticed a correlation between baby’s first latch and which breast is the “stud”? I’d love to hear your nursing experience, leave a comment below.
