How to Increase Breast Milk Supply Naturally: Tips for Australian Mums
One of the most common concerns for breastfeeding mums in Australia is whether they're producing enough milk. The truth is, most mums produce exactly what their baby needs — but there are times when supply genuinely needs a boost, and there are evidence-based ways to support your body to make more.
Whether you've had a difficult start, you're returning to work and worried about keeping up your supply, or you're just not sure if your baby is getting enough, this guide covers practical, natural strategies recommended by Australian health experts.
How Breast Milk Supply Works
Understanding the basics of milk production makes the tips below much easier to put into practice. Breast milk works on a supply-and-demand basis: the more frequently and effectively milk is removed from your breasts, the more your body produces.
Two hormones drive this process. Prolactin tells your body to make milk, and oxytocin causes the let-down reflex that releases it. Both are triggered by your baby suckling — or by expressing. The more stimulation your breasts receive, the higher your prolactin levels, and the more milk you produce.
According to the Raising Children Network, frequent, effective feeding is the most reliable way to build and maintain breast milk supply.
Signs Your Supply May Be Low
Before trying to increase supply, it helps to know whether there's actually a problem. Some signs that are not reliable indicators of low supply include: feeling like your breasts are less full than usual, your baby feeding very frequently, or your let-down being less noticeable. These are often normal.
Signs that may indicate genuinely low supply include:
- Your baby is not gaining weight as expected
- Your baby has fewer wet and dirty nappies than normal (fewer than 6 wet nappies a day after day 4)
- Your baby seems unsatisfied after most feeds
- You're consistently expressing very small amounts
If you're concerned, speak with a lactation consultant, your midwife, or your child health nurse. The Australian Breastfeeding Association also has a 24-hour helpline on 1800 686 268.
Natural Ways to Increase Breast Milk Supply
1. Feed More Frequently
The most effective way to boost supply is simply to breastfeed more often. Offer both breasts at each feed, and let your baby feed on demand rather than to a strict schedule. Aim for at least 8–12 feeds in 24 hours, especially in the early weeks. Feeding more frequently signals to your body that more milk is needed.
2. Ensure an Effective Latch
A baby who is well-latched can remove milk much more efficiently than one who isn't. An effective latch stimulates the breast more thoroughly and ensures your baby is getting enough milk at each feed. If you're unsure about your baby's latch, a lactation consultant can help you get it right. The Australian Breastfeeding Association can connect you with accredited consultants across Australia.
3. Switch Sides More Than Once
Offering each breast multiple times during a single feed — switching sides whenever your baby's sucking slows — triggers your let-down reflex again and encourages stronger stimulation. This technique, sometimes called switch nursing, is particularly helpful for mums trying to increase supply.
4. Express After Feeds
Expressing for a few minutes after breastfeeding helps remove any remaining milk from your breasts, signalling your body to produce more. Even if very little comes out, the act of expressing tells your body demand is higher than supply. A gentle, efficient pump makes this easier to fit into your routine.
5. Try Skin-to-Skin Contact
Holding your baby skin-to-skin — especially in the early days and weeks — naturally boosts prolactin and oxytocin levels. Even outside of feeds, plenty of skin-to-skin time can have a positive effect on supply. It also supports bonding and helps your baby cue for feeds more readily.
6. Feed at Night
Prolactin levels are naturally higher at night, making nighttime feeds particularly effective for building supply. If your baby is sleeping longer stretches and your supply seems to be dropping, offering a feed or expressing in the night can make a meaningful difference.
7. Rest, Eat Well, and Stay Hydrated
Stress and exhaustion can genuinely affect milk supply. While it's not always easy to rest with a newborn, trying to sleep when your baby sleeps, accepting help when it's offered, and eating a balanced diet rich in whole foods all support healthy milk production. Staying well-hydrated is also important — keep a water bottle nearby during every feed and expressing session.
8. Avoid Unnecessary Formula Top-Ups
Every formula feed your baby has is a feed your breast doesn't receive the signal for. Unless medically necessary, unnecessary top-ups can gradually reduce your supply. If you feel you need to supplement, talk to a lactation consultant or your GP about how to do so while protecting your supply.
Returning to Work and Maintaining Supply
Going back to work is one of the most common reasons Australian mums worry about their supply. The good news is that with a little preparation, many mums successfully continue breastfeeding after returning to work.
The key is to replace every feed your baby has while you're at work with an expressing session. Keeping a consistent schedule — expressing at the same times you would normally feed — helps maintain your supply. A reliable, portable bottle warmer makes it easy to warm your expressed milk at work or at day care. View our portable bottle warmers →
Building a freezer stash of expressed milk in the weeks before you return to work takes the pressure off. Read our guide on breast milk storage guidelines for Australian parents to understand how long your milk stays safe in the fridge or freezer.
What About Galactagogues (Foods and Herbs)?
You may have heard about foods or supplements claimed to boost milk supply — oats, fenugreek, fennel, and brewer's yeast are commonly mentioned. While some mums find these helpful anecdotally, the evidence for most galactagogues is limited.
The Australian Breastfeeding Association recommends focusing on frequent, effective feeding as the primary strategy, and consulting a healthcare professional before taking any herbal supplements, as some may interact with medications or affect your baby.
A nutritious, balanced diet matters more than any single food. Focus on getting enough calories (breastfeeding increases your energy needs), eating plenty of fruits, vegetables, whole grains, and lean protein, and drinking plenty of water throughout the day.
When to Seek Help
If you've tried the strategies above for a week or two and your supply still doesn't seem to be improving, it's time to seek support. A lactation consultant can assess your baby's latch, your feeding technique, and other factors that might be affecting supply.
In some cases, low supply has an underlying medical cause — such as retained placenta, thyroid issues, or insufficient glandular tissue — that requires medical attention. Don't struggle alone. Australian mums have access to excellent support through the ABA, maternal child health nurses, and private lactation consultants.

Frequently Asked Questions
How quickly can I increase my breast milk supply?
With consistent, frequent feeding or expressing, most mums start to notice an improvement in supply within 2–5 days. The body responds relatively quickly to increased demand, but it can take 1–2 weeks to see a significant change. Consistency is key — don't give up after just a day or two.
Does drinking more water increase breast milk supply?
Staying well hydrated supports overall milk production, but drinking excessive amounts of water won't directly increase supply on its own. Aim to drink to thirst — keep a water bottle nearby during every feed and expressing session, and make sure you're not becoming dehydrated, especially in Australia's warmer months.
Can stress reduce breast milk supply?
Yes — high stress levels can interfere with the let-down reflex and, over time, may affect supply. Oxytocin (the hormone responsible for let-down) is sensitive to stress and anxiety. This doesn't mean you need to be completely relaxed to breastfeed, but managing stress where possible, getting rest, and having support around you all make a difference.
Is it normal for breast milk supply to drop suddenly?
A sudden drop in supply can happen for a few reasons: illness (in you or your baby), your period returning, changes to your feeding schedule, or increased stress. Most drops are temporary and supply will rebound with more frequent feeding. If the drop is significant or doesn't recover, seek support from a lactation consultant.
Will pumping help increase my milk supply?
Yes, expressing in addition to (or instead of) breastfeeding can help increase supply by providing additional stimulation. Pumping after feeds, or replacing skipped feeds with expressing sessions, sends a clear signal to your body to produce more milk. A quality breast pump that effectively empties the breast gives the best results.
How do I know if my baby is getting enough milk?
The most reliable signs are weight gain and wet nappies. A baby who is gaining weight consistently and having at least 6 wet nappies per day (after day 4) is almost certainly getting enough milk. If you're concerned, your maternal child health nurse or GP can check your baby's growth and give you personalised reassurance.
