You're sitting on the sofa with the pump, and after twenty minutes there's barely anything in the bottle. You feel your breast and it's soft, almost slack. You've hardly been leaking lately, and that let-down, the tingling that pushes your milk forward, you never really feel it any more. And your baby? He seems to want to hang off you all evening, as though he's starving. Then comes the thought almost every breastfeeding mother has at some point: am I making too little?
Almost everyone worries about this. And almost nobody actually has too little milk. That's reassuring, and it's true, but the reason why matters more: you're reading your milk supply off the wrong signals. A soft breast, not much leaking, not much coming out of the pump and a baby who wants to feed constantly, those are exactly the four things that throw you off. They feel like proof of a shortage, and they tell you nothing about it.
Short answer: your breast lies, your baby's nappy tells the truth. The only reliable measure is whether your baby is growing and doing enough wees and poos, not how full your breast feels or how much comes out of the pump. And there's one distinction that clears away most of the needless panic: a slow let-down (your milk is slow to get going) is a completely different thing from low supply (there genuinely isn't enough). Below you'll find the four false alarms, the real measure you can actually trust, the difference between slow and low, whether tea and fenugreek do anything, and the clear line for when it is time to call a lactation consultant or a doctor.
The four false alarms: why the feel of your breast fools you
These four come up on every forum, and all four are wrong. They're the classic myths of the early weeks.
Myth: a soft breast means my milk is running out. In the first weeks your breasts are often full and tight because your body doesn't yet know how much to make. Somewhere between weeks six and twelve your supply settles to what your baby asks for, and your breasts go softer, including just before a feed. That isn't a sign it's dwindling, it's your body becoming efficient. A soft breast makes perfectly good milk. As mothers reassure each other on the forums: as long as your gut tells you he's drinking well and your breast feels slack afterwards, nothing's wrong.
Myth: I don't leak any more, so I'm making too little. Leaking is about how your let-down reflex behaves and how settled your supply is, not about how much you make. Plenty of mothers leak a lot early on and barely at all after a few months, while making the same amount or more. Less leaking is usually a sign your body has found its rhythm.
Myth: I can hardly pump anything, so there's hardly anything there. This is probably the most stubborn one. A pump is not a measuring device, it's a machine that works well for one woman and barely at all for the next. A baby who's latched well takes the milk out far more efficiently than any pump can. How much you pump depends on your machine, on the flange, on how relaxed you are and on whether your body responds to that bit of plastic at all. Countless mothers who could hardly pump a drop went on to feed happily for months or years. The pump shows you what the pump can get out, not what you make.
Myth: my baby wants to feed constantly, so he's not getting enough. A baby who feeds every hour in the evening and never seems satisfied looks like a hungry baby. Most of the time it's cluster feeding: normal baby behaviour, often in the evening or during a growth spurt, where he feeds little and often precisely to drive your supply up. Wanting to feed a lot doesn't mean getting too little. A baby who feeds often and grows well and has enough wet nappies does not have a supply problem.
The real measure: growth and nappies, the proof you can actually believe
If the feel of your breast lies, what does tell the truth? What comes out the other end. Your baby processes the milk, and that's visible, checkable and honest. On the forums this answer keeps floating to the top: good wet nappies and poos, and there's nothing to worry about.
Here's what to watch for:
- Wet nappies. From around day five or six you'd expect about five to six properly wet nappies a day, with pale, almost colourless wee. Dark, concentrated wee or far fewer wet nappies is a reason to look more closely.
- Poos. In the first weeks a breastfed baby poos regularly, often soft and yellowish. After the first few weeks it can become less frequent, and that's normal.
- Growth. Your baby loses a little in the first days (up to about seven to ten per cent of birth weight is normal) and is back to birth weight by around two weeks. After that he grows steadily. This is the number that really counts, and the one thing you don't have to guess at yourself: your health visitor weighs your baby at the baby clinic and plots it on the growth chart in the red book.
- Alertness. A baby who's getting enough is awake between feeds, alert and settleable. A baby who grows steadily drowsier and floppier and is hard to wake for a feed is a warning sign, not a reassuring one.
If these four line up, your baby is getting enough, whatever your breast whispers and whatever the pump does. If you want to go deeper into the signs of a content, well-fed baby, read the signs your baby is getting enough milk.
Slow let-down or low supply? The distinction that lifts the panic
This is where two very different things get muddled up, and pulling them apart takes away the biggest worry for a lot of mothers.
The let-down reflex is the reflex that gets your milk flowing. When your baby feeds or you start pumping, the hormone oxytocin is released, and it squeezes tiny muscles around your milk glands so the milk pushes forward. For one woman that feels like tingling or a sharp pull, for another like nothing at all. And that last one is very common: a great many mothers never feel their let-down and feed for years without a hitch. Not feeling the reflex doesn't mean it isn't working.
A slow let-down is something else: your milk does come, but it's slow to get going. At the breast you barely notice, but at the pump it shows, because it takes an age before anything appears. A slow let-down is about timing, not amount. It's held back by stress, tension, pain, cold or rushing, exactly the things that work against oxytocin. What helps: taking a moment to settle, warmth (a warm flannel or a warm shower just before a feed), not staring at the bottle, thinking of your baby or looking at a photo, and a gentle massage. As soon as you relax, the milk comes faster.
Low supply is different again: even when the let-down comes along fine, there simply isn't enough being made. That's the rare situation. Whether it's happening isn't something you read off your breast or your pump, but off the growth and the nappies above.
The distinction changes what you do. With a slow let-down you work on relaxation and timing. If you genuinely suspect low supply, you go to the signs and the help further down this guide. And with a very forceful, spraying let-down and a baby who chokes, it's often the opposite at play: oversupply. What to do about that is in what helps with an overactive let-down and too much milk.
Tea, fenugreek and extra pumping: does any of it really work?
The moment the worry hits, a lot of mothers reach for everything at once: nursing tea, fenugreek capsules, lactation cookies, oats, extra water and, just to be safe, a bit more pumping. Understandable, but usually it's firing at a problem that isn't there.
Two things are worth knowing honestly here. First: for most of these things, the so-called galactagogues, the evidence is weak. International breastfeeding doctors (the Academy of Breastfeeding Medicine) stress that there's little hard evidence that herbs or cookies genuinely raise supply, and that you always look at the cause first rather than at a pill or a tea. Second: if anything does steer your supply, it isn't the tea but the demand. Milk supply works on supply and demand: the more often and the more fully a breast is drained by feeding or pumping, the more you make. A breast that's emptied often gets the order for more.
Which also means: extra pumping can help, but only if there genuinely is too little and you do it deliberately to get more milk removed, ideally with a lactation consultant guiding you. Piling up remedies when there's no shortage does nothing, costs money and feeds the anxiety. And quietly topping up with a bottle because you're unsure can work against you: your baby then feeds less at the breast, your breast gets less demand and makes less. Before you go down that road, the question is always first: according to the growth and the nappies, is there actually a problem?
When it can be low supply: the signs that count
Reassurance mustn't paper over the small group it does affect. True low supply is rare, but it exists, and then getting help quickly matters. These are the signs that do point to low intake, and you see them in your baby, not on your breast:
- Too few wet nappies or dark, concentrated wee after day five.
- Ongoing weight loss or no weight gain, or a baby who still hasn't got back to birth weight by two weeks.
- Little poo, or very hard, dry poo after the first week.
- A drowsy, floppy baby who's growing less and less alert, hard to wake for a feed, or with barely any strength left to suck.
- Signs of dehydration such as a dry mouth, few tears or a sunken soft spot (fontanelle).
Just as important: there are causes that really can hold your supply down, and you won't fix those with tea. Think of a baby who isn't latching well or isn't getting enough time at the breast (by far the most common reason, and often fixable), sticking too rigidly to a schedule instead of feeding on demand, a retained piece of placenta after the birth, thyroid or hormonal issues such as PCOS, too little glandular tissue, previous breast surgery, or certain contraception containing oestrogen. If you recognise any of that, it's a reason to have it looked at by a professional rather than trying to sort it yourself.
When do you call a lactation consultant or a doctor?
Worrying about your supply is almost never a reason to panic, but there's a clear line for when you get help instead of waiting it out.
Contact a lactation consultant, your health visitor or your midwife if:
- your baby has fewer wet nappies than described above, or dark wee, and it keeps up;
- your baby isn't gaining, keeps losing, or is still under birth weight after two weeks;
- your baby is growing drowsier and floppier instead of more alert, or is hard to wake for a feed;
- feeding stays painful or you keep feeling he isn't latching well;
- you honestly stay worried even when the numbers look fine, because a lactation consultant can watch a feed and do a weighed feed that can put your mind at rest.
Call your GP straight away (out of hours, your local out-of-hours GP service or NHS 111) if there are signs of dehydration such as a dry mouth, few or no tears or a sunken soft spot. That's no longer a breastfeeding question, that's about your baby.
Call 999 or go straight to A&E if your baby is noticeably floppy and hard to wake. That is a medical emergency, not something to wait on or to phone the GP about first.
A lactation consultant is usually an IBCLC, sometimes through your midwife, your health visitor or in private practice. In the early weeks your midwife or health visitor can help too. A quick weigh-in at your baby clinic is the fastest way to shake off that nagging feeling: the number on the growth chart is more honest than anything else.
Comfortable feeding through the long days
For the days when your baby wants to feed every hour and your mood swings up and down, a good bra changes nothing about your supply. What it does do is make all that feeding less of a faff. If you're spending a big chunk of your evening getting dressed and undressed, a clip that opens one-handed and a band that gives while your size is still shifting really does make it more comfortable.
Our nursing bra is wireless and knitted from a soft, giving fabric that supports your breasts without pressing hard anywhere, with a clip that opens one-handed. It's made from an OEKO-TEX Class I certified fabric (certificate number 11-36224), the strictest category for textiles that touch a baby's skin. If you'd like everything on milk supply and breast problems in one place first, go to the overview of milk supply and breast problems. And you can see the bra itself here: see the nursing bra.
Frequently asked questions about low milk supply
Does a soft breast mean my milk is running out?
No. In the first weeks your breasts are often full because your supply hasn't settled yet. Somewhere between weeks six and twelve your body adjusts production to demand and your breasts go softer, including just before a feed. That's not a sign of less milk, but of a body that's become efficient. A soft breast makes just as much milk.
I can't feel my let-down, is something wrong?
Very probably not. Many mothers never feel their let-down and feed for months or years without any problem. That tingling or sharp pull says nothing about how much milk is coming. The real measure stays whether your baby is growing and has enough wet nappies, not whether you can feel the reflex arriving.
I can hardly pump anything, does that mean I have low supply?
Usually not. A pump is not a measuring device: a well-latched baby takes milk out far more efficiently than a pump does. How much you pump depends on your machine, the flange, how relaxed you are and how your body responds to the pump. Don't look at the bottle, look at your baby's growth and nappies. That's the reliable measure.
Does nursing tea or fenugreek really help me make more milk?
For most of these the evidence is weak. What does steer your supply is demand: the more often and more fully you drain the breast by feeding or pumping, the more you make. So first check whether the growth and the nappies actually show a shortage at all, and with real concerns bring in a lactation consultant rather than piling up remedies.
How many wet nappies should my baby have?
From around day five or six you'd expect about five to six properly wet nappies a day, with pale, almost colourless wee, plus regular poos in the first weeks. Clearly fewer wet nappies, or dark concentrated wee that keeps up, is a reason to look more closely and get in touch with your health visitor or a lactation consultant.
