Breastfeeding from just one breast

It is common to believe that a baby must systematically nurse from both breasts at every meal to achieve a balanced diet. However, many mothers breastfeed using only one breast, whether by choice, medical necessity, or because their baby shows a marked preference. The good news is that yes, you can produce enough milk to nourish your baby using just one breast.

However, one-sided breastfeeding can take several forms: using a single breast for temporary or permanent health reasons, or offering just one breast per feed (which is common in the first few days). Here is what you need to know to manage this situation with peace of mind.

Why choose or need to breastfeed from just one breast?

There are many reasons why a mother might feed her child from only one side. This can be temporary, become a long-term habit, or prove necessary.

Past breast surgery: Interventions may have removed breast tissue or damaged milk ducts, rendering one breast unable to produce milk.
Physical limitations or pain: An injury, medical condition, or persistent pain can make nursing on one side difficult or impossible.
Breast or nipple issues: Recurrent problems (such as cracked nipples, infections, or mastitis) may lead you to wean from one breast temporarily.
Baby's preference: Some babies strongly favor one breast, which can lead to a drop in production on the other side.
Medical advice: You may be advised to stop breastfeeding from one breast following surgery, treatment, or a condition specifically affecting that side.

Each breast works independently

Breastfeeding is based on the principle of supply and demand. Each breast responds separately to the frequency of feeds. The more your baby nurses on one side, the more milk that breast will produce. This is why a single breast can suffice to provide a full supply. Just as mothers of twins produce enough milk for two babies, your body adjusts to meet your child's needs.

Over time, the less-used breast will naturally produce less milk and may eventually stop producing if it no longer receives stimulation. If the situation is temporary, support is available to help your baby return to the other breast. If it is a long-term choice, know that one-sided breastfeeding can work perfectly.

What should I do if I must stop breastfeeding from one breast?

If a medical or physical condition forces you to stop breastfeeding on one side, you will need to gradually reduce nursing or milk expression on that breast to lower production. It is best to do this gradually to avoid inflammation or mastitis. However, there are cases where a rapid reduction is necessary.

My baby prefers one breast: is this normal?

It is quite common for breasts to differ in size, shape, and milk flow. Your baby might prefer:

* A faster or slower let-down reflex.

* A specific nipple shape.

* A specific head position, for example, in case of torticollis (stiffneck).

You might also notice:

* More milk on one side than the other.

* Different swallowing speeds.

* Differences in nipple shape.

* Your own preference for holding the baby on a certain side.

How to restore balance?

Yes, you can try to balance the situation and encourage nursing on the less-preferred breast:

1. Offer this breast first at every feed.

2. Return to this breast more often.

3. Use a breast pump on this side to extract more milk and stimulate production.

4. Try different positions to find the one that is more comfortable for your baby on this breast. My favorite position is the "Gestalt" position.

The breast that produces more milk will likely be larger than the other until complete weaning. Many mothers feel very uncomfortable about this and worry it will be noticeable. Wearing looser-fitting tops, especially in woven fabrics rather than knits, can help hide this imbalance. You can also consider using a bra filler to give the appearance of similar size.

Breastfeeding from one breast per feed: the solution for oversupply?

Reducing milk production by staying on the same breast

Breastfeeding from one breast per feed can be a useful method to reduce milk production. Mothers suffering from oversupply can use this technique to manage difficulties related to too much milk (engorgement, leaking, etc.). In this case, one-sided breastfeeding is generally temporary, lasting until the oversupply stabilizes, after which you can return to nursing from both breasts for most feeds.
