Is Increased Milk Supply from One Breast Common?

One Breast Producing More Milk – Is It Normal?

Doctors recommend exclusively breastfeeding babies for the first 6 months of their life. However, breastfeeding a baby isn’t always as easy as it sounds. Breastfeeding comes with its own complications. Sometimes, one of your breasts feels fuller than the other or one breast has a faster let-down reflex (release of milk from the breast).

Keep reading to understand why there are differences in breast milk supply, and how you can increase milk supply in both the breasts.

Is It Normal for One Breast to Produce More Milk?

Breasts produce milk according to the demand-and-supply rule. So, if you or your baby prefers, say the left breast over the right one, the left breast will produce more milk than the other. This could lead to low milk production in the other breast, which is quite normal. When your body senses that there is a greater requirement for milk from one side, it produces a larger quantity of breast milk on that side to meet the increased demand.

What Causes an Uneven Production of Milk in the Breasts?

There are several reasons for the uneven production of breast milk in a nursing mother. Some of them are:

1. The Baby/Mother Has a Breast Preference

If your baby favours one breast over the other and feeds more on the preferred side, there will be more milk supply in one breast. In nursing mothers, continuously breastfeeding on one side produces more milk in that breast. That’s because milk production and let-down reflex are triggered by the baby’s suckling.

2. Surgeries and Injuries

If one of your breasts has been operated on, milk production may reduce in that breast. Injuries can also affect breast milk production. If you’ve sustained an injury to a particular breast in the past, it may have damaged the milk ducts and reduced milk production.

3. Anatomical Differences

Both the breasts aren’t exactly the same. One breast can have more milk ducts than the other. The structure of the nipples also varies. It may be easy for your baby to latch on to the nipple of one breast than the other.

4. Variations in Let-Down Reflex

The force with which milk is released from the breasts also makes a difference. If the let-down reflex in one breast is less forceful than the other, the baby may not prefer to feed on that breast. Alternately, if the let-down is too forceful, the baby may have trouble swallowing quickly and may not prefer that side.

How to Encourage Equal Milk Production in Both the Breasts

There are some things you can do to stimulate your breasts to produce the same quantity of milk. Here they are:

  • Start breastfeeding from the breast that produces less milk. When your baby suckles from the less-preferred breast, it will stimulate breast milk production.
  • Use a breast pump to pump out the milk from the breasts after a nursing session. This will also help in increasing milk production. You can store this milk and feed it to the baby later. You can latch the baby in different positions to get the baby to drink milk from both the breasts. If not pumping, you can also dream feed your baby and latch the baby on the breast he/she prefers and gently slide the baby to another side without changing the position.

A mother using breast pump

  • Massage the less-preferred breast with your hand, and apply a warm compress to it for a few minutes. These techniques will stimulate milk production. However, do note that it may not work if the baby does not suck directly on that breast or if you don’t pump from this breast at all.
  • Try new nursing positions to make it comfortable for your baby to feed on the breast that produces less milk. Usually, the football hold helps but a mother should try this position if there is an overactive letdown. In case of an overactive letdown, a laid back position or football hold might help. Also, in case of an overactive letdown, hand expressing a bit before latching baby on directly can also help.
  • You can also offer the less-preferred breast when your infant is drowsy or tired.
  • Start with the breast that produces less milk and switch sides at least 2-3 times during each feeding.
  • Breastfeed whenever your baby wants it. Don’t delay or postpone feeding time. Emptying the breast increases milk production. Breastfeed every two hours or earlier if the baby demands it until the baby regains birth weight. After that, feed on demand. Just feed baby on demand and until the baby unlatches on his or her own. Remember: an improper latch on one side can lead to less milk transfer on that side and result in less milk production.

Correct breastfeeding position

  • Drink plenty of water and sleep well for optimal breast milk production. In case you feel that your milk production is low, you can speak to a lactation consultant about using a galactagogue. This is either a prescription medicine or a natural substance that helps to increase breast milk production. Some examples of herbal galactagogues include fenugreek leaves and seeds, garlic, fennel, barley, and alfalfa.

Does an Unequal Production of Milk Affect Your Baby?

As long as you nurse on demand, your baby will get enough breast milk to fulfil his nutritional needs. Even if one breast produces less milk, the other breast will produce more milk to compensate. You need not worry if you are feeding only from one breast as there are mothers who just feed from one side. The size of the breasts may differ, but you can feed from both sides equally to compensate for it.

All mothers have a different experience of breastfeeding their babies. You may panic if one of your breasts produces less milk but there’s no need to worry as long as you are feeding with the other breast. Your health also plays an important role in the production of breast milk, so take ample rest, eat nutritious foods and stay hydrated.
