How to get one breast to produce more milk

Many moms worry about low milk supply, even though most make exactly what baby needs.

Many moms worry about low milk supply, but most of the time your body makes exactly what your baby needs, even if you don't realize it. There are also ways to tell if your baby is getting enough milk. If you aren't making enough, there are ways you can build your supply. And your WIC breastfeeding staff is always there to help!

Am I Making Enough Milk?

First, look for these signs that your baby is getting enough milk. For example, pay attention to the number of wet and dirty diapers and your baby's weight gain.

Things you should NOT worry about:

  • How your breasts feel. Your breasts will feel softer and less full as your milk supply adjusts to your baby's needs. This does not mean you have low supply.
  • If your baby nurses for shorter periods of time, such as only 5 minutes on each breast.
  • If your baby's feeds are bunched together. This is called cluster feeding and happens when your baby starts nursing more often and for longer. This can happen in the evenings or because of growth spurts.
  • Not getting much milk when you express. Your baby is much more effective than a pump or hand expression at getting out milk. Find tips to help you pump.

If you are still concerned, talk to your baby's doctor about their growth.

Causes of Low Milk Supply

While most moms make plenty of milk, some do have low milk supply. This might happen if you:

  • Limit your baby's breastfeeding sessions. Remember, the more you feed on demand, the more milk you make.
  • Give your baby infant formula instead of breastfeeding.
  • Introduce solid foods before baby is 4-6 months old.
  • Take certain birth control pills or other medicine.
  • Don't get enough sleep.
  • Drink alcohol or smoke.
  • Have had breast surgery.

Talk to your doctor if you have hepatitis B or C, herpes, or diabetes. These conditions may also affect milk supply.

Increasing Your Milk Supply

Breastfeeding frequently—especially in the first hours, days, and weeks—is the main way to increase your milk supply. Your body will make milk to meet your baby's demand.

Try these tips to help you make more milk:

  • Breastfeed every time your baby is hungry. In the early weeks, your baby will eat 8-12 times every 24 hours. It's best not to put your baby on a strict feeding schedule. Follow your baby's cues, and let your baby tell you when it's time to eat.
  • Make sure your baby is latching well.
  • Offer both breasts at each feeding. Let your baby finish the first side, then offer the other side.
  • Empty your breasts at each feeding. Hand express or pump after a feeding to draw out all the milk and signal your body to make more.
  • Avoid bottles and pacifiers in the early weeks. Feed your baby from your breast whenever you can.
  • Get plenty of sleep, and eat a healthy diet.
  • Pump or express your milk. Pumping or expressing milk frequently between nursing sessions, and consistently when you're away from your baby, can help build your milk supply.
  • Relax and massage. Relax, hold your baby skin-to-skin, and massage your breasts before feeding to encourage your milk to let down.
  • Take care of yourself. Get plenty of rest, eat well, drink enough fluids, and let others help you.

Consider Charting Your Progress

Record how often your baby is breastfeeding, for how long, and on which sides. If you are supplementing with infant formula, record how much your baby is getting and decrease the infant formula as your milk supply increases. WIC breastfeeding staff can help you determine how much infant formula your baby needs.

Why does my one breast produce less milk?

“Many women also have different sized nipples, but will use the same size pump parts, so one side may not be fitting correctly causing it to not be as effective,” she explains. In this case, less milk would be removed, causing that breast to produce less milk overall.

How do you fix uneven milk production?

Breast compressions can be a great way to do this. To do breast compressions, massage the low performing side while you pump, moving your hands around and pushing as much milk out of the milk ducts as possible. Take a break every few minutes to let your hands rest and then start again.

Is it normal to produce more milk on one side?

Why does it happen? Possible reasons for variations in supply/milk flow between breasts: Normal anatomical differences. All women have one breast that has more working ducts and alveoli than the other (usually the left side, though either is normal).

How long does it take to increase milk supply in one breast?

The more frequently milk is removed, the better. After two or three days of regular pumping you should see a significant increase in supply. For advice on getting more milk from each pumping session, read breast pumping tips.
