How to Naturally Increase Your Breast Milk Supply

Noticing a sudden dip in your milk supply can be incredibly stressful. Whether you are dealing with a growth spurt, recovering from an illness, returning to work, or simply trying to build a freezer stash, struggling to pump enough milk is a very common challenge for mothers.

The good news is that breast milk production is driven by a simple biological rule: supply equals demand. If you consistently tell your body that it needs to make more milk, it will respond. Here are five proven, evidence-based methods to naturally increase your breast milk supply.

1. The Golden Rule: Empty Your Breasts More Frequently

Your breasts produce milk faster when they are empty and slower when they are full. If milk sits in your breasts, your body releases a protein called Feedback Inhibitor of Lactation (FIL), which signals your body to slow down production.

• Add a Pumping Session: If you currently pump 5 times a day, try increasing it to 6 or 7 times. Use your Pumping Tracker to monitor if this extra session increases your daily total over a 3-to-4 day period.
• Pump After Nursing: If you are nursing directly, try pumping for 10-15 minutes immediately after your baby finishes feeding to ensure your breasts are completely empty.
• Never Skip the Night Pump: Prolactin (the milk-making hormone) levels are highest between 1:00 AM and 5:00 AM.

2. Introduce “Power Pumping”

Power pumping is a technique designed to mimic a baby going through a growth spurt (often called “cluster feeding”). By rapidly turning the pump on and off over the course of an hour, you send a massive signal to your brain to produce more milk.

3. Optimize Your Pump and Flanges

Sometimes the issue isn’t your body; it’s your equipment. If your pump isn’t effectively removing milk, your supply will gradually drop.

• Check your Flange Size: Your nipple size can change throughout your pumping journey. If your flanges are too large, they will pull in too much areola. If they are too small, they will pinch and restrict milk flow. Use our Flange Sizing Calculator to ensure a proper fit.
• Try “Hands-On Pumping”: Massage and compress your breasts while the pump is running. Studies show that breast massage during pumping can significantly increase both the volume of milk expressed and its fat content.

4. Hydration and Lactogenic Foods

Breast milk is roughly 87% water. If you are dehydrated, your body will struggle to produce milk. You should aim for at least 100 to 128 ounces (about a gallon) of water per day while lactating.

While the science on “galactagogues” (foods that boost milk supply) is mostly anecdotal, thousands of mothers swear by adding specific nutrient-dense foods to their diet:

Lactogenic Food	Why it helps
Rolled Oats	High in iron; low iron is a known cause of low milk supply.
Brewer’s Yeast	Packed with B-vitamins, iron, and protein.
Flaxseed	Contains phytoestrogens that can support lactation.
Fennel & Fenugreek	Traditional herbs used for centuries to boost supply.

5. Manage Stress and Focus on the Let-Down

Stress is the enemy of milk production. High levels of cortisol (the stress hormone) directly inhibit the release of oxytocin, which is the hormone responsible for your “let-down” (the reflex that pushes milk out of the breast).

• Distract Yourself: Do not stare at the pump bottles watching the drips. Put on a TV show, read a book, or cover the bottles with a pair of baby socks.
• Look at Your Baby: Looking at photos or videos of your baby, or smelling one of their worn onesies, can trigger a strong oxytocin release.
• Use Heat: Apply a warm compress to your breasts for 5 minutes before pumping to encourage blood flow and a faster let-down.

Increasing your milk supply takes time. Stay consistent with your schedule, track your progress on your dashboard, and give your body at least 4 to 7 days to respond to the increased demand. You’ve got this, mama!
