The single most effective way to increase your breast milk supply is to remove more milk, more often. Your body produces milk on a supply-and-demand basis, so the more frequently and thoroughly your breasts are emptied, the more milk they make. That principle underlies nearly every strategy that actually works, from adjusting how your baby latches to adding extra pumping sessions.
How Your Body Decides How Much Milk to Make
Two hormones drive milk production. Prolactin tells your breast tissue to produce milk, and oxytocin triggers the muscle contractions that push milk out (the “let-down” reflex). Every time your baby suckles or you use a pump, nerve signals tell your brain to release both hormones. The more stimulation your breasts receive, the more prolactin your body produces, and the more milk follows.
There’s also a built-in braking system. When milk sits in the breast for too long without being removed, a protein in the milk itself signals your body to slow down production. This is why skipping feedings or going long stretches between sessions can cause supply to dip. Removing milk frequently keeps that brake from engaging.
Fix the Latch First
A shallow latch is one of the most common reasons babies don’t drain the breast well, and a breast that isn’t drained thoroughly sends the signal to make less milk. Before adding pumping sessions or supplements, it’s worth checking that your baby is actually transferring milk efficiently.
Signs of a good, deep latch: your baby’s mouth opens wide around the breast (not just the nipple), their lips flare outward like a fish, their chin presses into your breast, and their chest and stomach rest flat against your body with their head straight rather than turned to the side. You should hear or see rhythmic swallowing, and feeding shouldn’t be painful. If you’re feeling pinching or cracking, or your baby seems to slip off and re-latch repeatedly, the latch likely needs adjustment.
A lactation consultant can watch a full feeding and spot problems you might not notice on your own. Sometimes a simple change in positioning makes a dramatic difference in how much milk your baby removes per session.
Check for Tongue-Tie
If your baby struggles to latch deeply despite good positioning, tongue-tie may be the issue. This is a condition where the strip of tissue under the tongue is too short or tight, restricting movement. Signs include a tongue that looks heart-shaped when the baby sticks it out, difficulty lifting or moving the tongue side to side, and trouble staying attached for a full feed.
Babies with tongue-tie often feed for a long time, take a short break, then want to feed again. They may make clicking sounds during feeding and gain weight more slowly than expected. The poor milk removal can lead to cracked nipples, engorgement, and a gradual drop in supply. A simple procedure to release the tissue can often resolve breastfeeding difficulties quickly.
Nurse More Frequently
Because milk production is demand-driven, the simplest approach is to increase demand. Aim to breastfeed at least 8 to 12 times in 24 hours, and don’t watch the clock to space out feedings. Offering the breast whenever your baby shows early hunger cues (rooting, hand-to-mouth movements) keeps stimulation high and prevents milk from sitting too long.
Switching sides during a feeding can also help. Once your baby’s swallowing slows on one breast, switch to the other. You can go back to the first side again if your baby is still interested. This “switch nursing” gives each breast multiple rounds of stimulation per session.
Use Breast Compressions
When your baby is still latched but has slowed to light sucking or nibbling without much swallowing, gently squeezing the breast can turn those nibbles back into active drinking. Compressions mimic a let-down reflex and help push more milk toward the nipple, so your baby gets a fuller feeding without needing to work as hard. This technique works especially well in the first few days when colostrum volumes are small and every drop matters.
Try Power Pumping
Power pumping is a technique that mimics the cluster feeding a baby does during a growth spurt, sending your body repeated signals to ramp up production. The standard protocol fits into one hour:
- Pump for 20 minutes
- Rest for 10 minutes
- Pump for 10 minutes
- Rest for 10 minutes
- Pump for 10 minutes
Do one power pumping session per day in addition to your regular feeding or pumping routine. Most people see results within two to three days, at which point you can return to your normal schedule. Power pumping works best as a short-term boost rather than a permanent routine.
If you’re exclusively pumping, adding even one extra standard session per day (especially one during the night, when prolactin levels are naturally highest) can nudge supply upward over the course of a week.
Skin-to-Skin Contact Helps
Holding your baby against your bare chest triggers oxytocin release in a pulsatile pattern, which directly supports the let-down reflex. You don’t have to be actively feeding for this to work. Spending time in skin-to-skin contact between feedings encourages your baby to nurse more often and helps your hormonal system stay primed for milk production. It also calms both of you, which matters because stress can temporarily suppress oxytocin.
Eat and Drink Enough
Making milk takes energy. The CDC recommends breastfeeding mothers consume an additional 330 to 400 calories per day compared to what they ate before pregnancy. This isn’t the time for aggressive calorie restriction. You don’t need a special diet, just regular meals with enough protein, fat, and carbohydrates to fuel your body’s extra work.
Hydration matters too, though drinking excessive water won’t increase supply beyond what your body naturally needs. A practical rule: keep a water bottle nearby and drink when you’re thirsty, which for most breastfeeding mothers is often.
Herbal Supplements: Limited Evidence
Fenugreek is the most widely discussed herbal supplement for milk supply, and many mothers report that it helps. However, no formal clinical studies have confirmed its effectiveness. Its proposed mechanism is stimulation of sweat production (the breast is technically a modified sweat gland), but that theory hasn’t been validated either.
Fenugreek also comes with a meaningful list of potential side effects. It can cause diarrhea in both mother and baby, lower blood sugar, interact with blood thinners, worsen asthma symptoms, and cause a distinctive maple-syrup smell in sweat and urine. It should not be used during pregnancy because it can stimulate the uterus. Other herbs sometimes mentioned, including blessed thistle, fennel, and anise, have only anecdotal evidence behind them. The fact that these products are natural does not mean they’re risk-free, and their potency can vary between brands.
If you want to try an herbal galactagogue, it’s worth weighing the lack of proven benefit against the real possibility of side effects, particularly if you have diabetes, asthma, or take blood-thinning medication.
Prescription Options
When non-medical strategies haven’t been enough, some doctors prescribe medications that increase prolactin levels as a side effect of their primary action. These are typically considered only after a thorough evaluation of feeding technique and frequency, and they work best when combined with continued breast stimulation rather than used alone.
The most commonly used prescription option outside the United States works by blocking a chemical signal in the brain, which causes prolactin to rise. Side effects are generally mild (dry mouth, headache, stomach cramps), though rare cardiac concerns exist for people with a history of heart rhythm problems. The medication used more often in the U.S. carries a stronger side-effect profile, including drowsiness, anxiety, restlessness, and in rare cases, a movement disorder that prompted a serious safety warning from the FDA. Both medications require a prescription and monitoring.
How to Tell If Your Supply Is Actually Low
Many parents worry about low supply when their baby is actually getting plenty of milk. Breasts feeling softer, shorter feeding sessions as your baby gets more efficient, or not pumping much output (pumps are less effective than babies at removing milk) are not reliable signs of low supply.
The most trustworthy indicator is diaper output. After the first five days of life, a breastfed newborn should produce at least six wet diapers per day. Steady weight gain along your baby’s growth curve is the other key measure. If diapers and weight are on track, your supply is likely fine even if it doesn’t feel that way.
If diapers are consistently below that threshold or weight gain has stalled, that’s a signal to work with a lactation consultant who can observe a full feeding, weigh your baby before and after to measure transfer, and help you build a targeted plan rather than guessing at what might help.
