The most effective way to increase your breast milk supply is to remove milk from your breasts more frequently and more thoroughly. Milk production works on a supply-and-demand basis: the more milk you remove, the more your body makes. Most other strategies, from skin-to-skin contact to herbal supplements, work best as additions to this core principle.
How Your Body Regulates Milk Production
Two hormones drive milk production. Prolactin, released during pregnancy and each time your baby nurses, tells your breast tissue to produce milk. Oxytocin, released during feeding and physical closeness with your baby, widens the milk ducts and triggers the “let-down” that moves milk toward the nipple.
There’s a third piece that matters just as much: a protein naturally present in breast milk that acts as a built-in brake. When milk sits in the breast without being removed, this protein signals your body to slow production. When the breast is emptied, the brake releases and production speeds up. This is why skipping feeds or going long stretches between pumping sessions can quietly tank your supply, and why frequent, thorough emptying is the single most important thing you can do.
Feed or Pump More Often
Newborns typically nurse 8 to 12 times in 24 hours, and hitting the higher end of that range sends a stronger production signal. If your baby is willing, offer the breast more frequently rather than waiting for hunger cues. Shorter gaps between feeds keep that built-in inhibitor from accumulating and slowing things down.
If you’re exclusively pumping or supplementing with a pump, aim for at least 8 sessions per day, including at least one overnight session. Prolactin levels tend to be highest in the early morning hours, so a pump session between 1 a.m. and 5 a.m. can be particularly productive. Make sure each session fully drains the breast rather than stopping at a set time. Pumping for two to three minutes after the last drops of milk helps signal your body to produce more at the next session.
Try Power Pumping
Power pumping mimics the cluster feeding pattern babies naturally do during growth spurts. You dedicate one hour and cycle through pumping and resting intervals: pump for 20 minutes, rest for 10, pump for 10, rest for 10, then pump for 10 more minutes. This rapid, repeated stimulation sends a concentrated burst of demand signals to your hormonal system.
Most people do one power pumping session per day, replacing one of their regular pump sessions, and continue for three to seven days before evaluating results. It’s not instant. You’re essentially placing an order with your body that takes a few days to fill.
Use Breast Massage and Hand Expression
Adding breast massage to your routine, whether you’re nursing or pumping, helps extract more milk per session. A WHO-reviewed trial found that women who massaged their breasts during expression got measurably more milk, and that milk had a higher fat content. The technique is straightforward: use your fingertips to gently compress and stroke the breast tissue from the outer edges toward the nipple, both before and during pumping or feeding.
Hand expression after a pump session can also catch milk that the pump leaves behind. Even a few extra milliliters per session adds up over the course of a day, and the extra emptying reinforces the supply signal.
Spend More Time Skin to Skin
Holding your baby directly against your bare chest stimulates oxytocin release, which improves let-down and can boost overall milk volume. UNICEF guidelines note that expressing milk after a period of skin-to-skin contact tends to yield more volume. This isn’t just a newborn strategy. Skin-to-skin contact works at any age and is especially worth trying if you’re going through a supply dip. Even 20 to 30 minutes of chest-to-chest contact before a feeding or pumping session can make a noticeable difference.
Eat and Drink Enough
Making milk costs energy. Breastfeeding burns roughly 450 to 500 extra calories per day, and consistently undereating can suppress production. You don’t need to count calories precisely, but if you’re skipping meals, dieting aggressively, or noticing your supply drop alongside weight loss, that’s a sign to eat more. Focus on regular, balanced meals rather than specific “lactation foods.” No single food has strong evidence for boosting supply on its own.
Hydration matters too, though drinking beyond your natural thirst doesn’t appear to increase supply further. A practical guideline is to keep water nearby and drink whenever you’re thirsty, which for most breastfeeding parents means quite a lot. If your urine is dark yellow, you’re likely not drinking enough.
Herbal Supplements: Limited Evidence
Fenugreek is the most widely discussed herbal galactagogue, but no formal clinical studies have confirmed it works. The evidence is entirely anecdotal, dating back to reports from the 1940s. Meanwhile, fenugreek carries a real list of potential side effects: nausea, diarrhea (in both you and your baby), worsening of asthma symptoms, low blood sugar, excessive sweating, and a distinctive maple syrup smell in sweat and urine. It can also interact with blood thinners and diabetes medications.
Other herbs commonly marketed for milk supply, including blessed thistle, fennel, and anise, have even less evidence behind them. If you want to try an herbal supplement, it’s worth knowing that you’re essentially running an experiment on yourself with uncertain benefit and real potential for side effects.
Prescription Galactagogues
When behavioral strategies aren’t enough, some healthcare providers prescribe medications that work by raising prolactin levels. Domperidone is the most commonly used, typically prescribed at a low dose three times daily for an initial seven-day trial. It does increase prolactin, but the key factor seems to be the sudden spikes in prolactin triggered by nipple stimulation rather than the overall level, which is why medication works best alongside frequent feeding or pumping, not as a replacement for it.
Domperidone carries a small increased risk of heart rhythm problems, particularly at higher doses or with prolonged use. Very little passes into breast milk (less than 0.5% of the mother’s dose), and no serious side effects have been reported in exposed infants, though monitoring for feeding difficulties or digestive changes is recommended. Withdrawal symptoms including anxiety, insomnia, and headaches can occur when stopping the medication, so tapering rather than stopping abruptly is standard practice. Other prescription options like metoclopramide exist but have weaker evidence and additional side effect concerns.
How to Tell if Your Supply Is Actually Low
Before overhauling your routine, it’s worth confirming that your supply is genuinely low rather than responding to normal variations that feel alarming. Breasts that feel softer than they did in the early weeks, a baby who finishes feeding quickly, or a baby who wants to nurse frequently are all normal and don’t indicate low supply.
The reliable indicators are in your baby’s output and growth. By five to seven days old, your baby should produce six or more wet diapers per day with pale or nearly colorless urine. Newborns commonly lose up to 8% to 10% of their birth weight in the first few days, then start gaining steadily. If your baby is meeting these benchmarks, your supply is likely fine even if it doesn’t feel that way. If your baby isn’t meeting them, that’s useful information to bring to a lactation consultant who can watch a full feeding and identify whether the issue is production, milk transfer, latch, or something else entirely.
