Somewhere on a forum sits a mother who has been feeding for 6 months and still wears breast pads every day. She writes: "I'm 6m pp & have been EBF for 6m. I'm still wearing nursing pads, if I don't my shirt is completely drenched. [...] I keep getting told that my milk supply will regulate but it's been long enough hasn't it?" Everyone keeps telling her it will stop once her supply settles. And there she sits, wondering whether her body somehow works differently.
Chances are you've landed at the same point. Search for how long the leaking lasts and one site says 6 weeks, the next says 6 to 12 weeks, and yet another says 3 to 6 months. Every number stated with the same confidence. And the moment your body sails past whichever number you read, the nagging starts: am I the exception?
No. The short answer: the range mothers themselves report runs from roughly 1 month to well past 6 months, and a small group leaks now and then for as long as they feed. Every point in that range is normal. There is only one sign where you shouldn't sit it out, and it has nothing to do with how long it's been. You'll find it further down, after the real numbers.
Why every site gives you a different number
Those recommendations aren't made up. They each describe a real slice of the picture, and almost all of them hang on the same anchor: the leaking stops once your milk supply regulates to your baby. For many women that settling happens somewhere between 6 and 12 weeks. Reach that point early and you'll recognise yourself in the site that promises 6 weeks. Take longer, or make milk generously, and 3 to 6 months will ring true. Every editorial team took one group of mothers and turned their experience into the rule.
Up to there it's understandable. But underneath all those numbers sits a deeper mistake. You only spot it once you look at mothers whose supply had demonstrably regulated long ago.
Regulated is not the same as dry
Read these two back to back. A mother of a baby of five and a half months: "When I was freshly postpartum, I leaked like crazy but assumed it would stop when my supply regulated. Well, it has, and I still leak!" And another, a little over 3 months after giving birth: "I'm a little over 3 months in and still leaking from the opposite boob, too. Even though my supply regulated sometime between 6-8 weeks."
Two women well past the promised moment. Supply settled, breasts softer, everything by the book. And still they leak.
That's possible because regulating and leaking are about two different things. Regulating is about how much milk you make: your body learns your baby's demand and stops producing in stock. Leaking is about the let-down reflex, the signal that makes your milk flow. That reflex responds to your baby, to crying, to warmth, to a full breast. It takes very little notice of the moment your amounts line up. In one woman the system shuts down early and neatly. In another the reflex keeps letting milk through for months while her supply has long been in order. How that interplay runs phase by phase, from the first week through to weaning, is in when does the leaking stop: patterns from week 1 to weaning.
So still leaking past the promised number says nothing about your milk and nothing about you. It only says that the anchor all those numbers hang on is too simple.
One forum question, a handful of different end dates
The most honest numbers aren't in the advice pieces themselves. You'll find them in the comments underneath. A mother who was leaking through everything 2 weeks after giving birth asked on Reddit when it stopped for others: "When did you stop leaking? I feel like I'm constantly leaking through my bra and shirts." The replies cheerfully contradicted each other.
- Around 6 weeks: "I regulated around 6 weeks and stopped leaking at each feed, I think everyone is different."
- Still in full flow at 12 weeks, certainly at night: "I just woke up wet everywhere cause I forgot to put pads on last night and I am 12 weeks PP lol."
- Dry in the daytime at 3 months, the nights much later: "About three months for me which is when I went back to work. [...] I leaked every night until like 10 months tho."
- And the long end: "I stopped leaking around 9 months."
In another thread, a mother of a 4-month-old says she still leaks between feeds and mostly wants to know whether it ever eases off. She falls within the range too.
The woman who asked read all those replies and wrote down what no advice site dares to put in print: "According to these comments everyone is leaking/stopped leaking at way different times." That is the real answer. The end date isn't a number but a range, and in this one thread it already runs from 6 weeks to 10 months.
Three patterns inside the chaos
A wide range doesn't mean it's random. Lay enough of those stories side by side and 3 patterns rise to the surface. Worth knowing, because then you know where you probably stand and what will change first. This article belongs to our full guide to leaking, the let-down reflex and staying dry; here we stick to how long it lasts.
Random daytime leaking usually stops first
In the first weeks your milk lets down at almost anything: a crying baby in the supermarket, a warm shower, simply thinking about your little one. That random leaking belongs to the start-up phase, when your body is still producing in stock. As your supply settles, your breasts feel softer and mostly release milk when someone is actually drinking. For most women this is the first part to disappear.
The nights run months behind the days
At night you get the longest gap between two feeds. If your baby sleeps 4 or 5 hours in one stretch, that's wonderful news and, at the same time, the moment a full breast simply overflows. That explains the mother above who was dry in the daytime at 3 months and leaked at night until 10 months: her baby slept that well. If you're already dry by day but still waking up wet, you're not going backwards. You're in the second pattern. What you can practically do about it at night is in night-time leaking: what to wear in bed without soaking through.
Leaking from the other breast lasts longest
The let-down reflex makes no distinction between left and right. While your baby drinks on one side, the milk gets going on the other side too. For many women this is exactly the part that hangs on longest, well past the point where all the other leaking has stopped. The mother of five and a half months above only leaked at this moment. Leaking from the other side during a feed is pure reflex and no sign of oversupply. If your breasts still feel hard after the first months, if the milk sprays so forcefully that your baby splutters, or if you keep losing milk all day long, take a look at oversupply and a strong let-down reflex.
You can keep leaking for months without breastfeeding at all
On parenting forums you'll find one more group that fits no list at all: mothers who aren't breastfeeding and keep leaking anyway. One bottle-feeding mum found it took about 4 weeks, with hardly anything left in the last week but still a little. Another never breastfed and kept losing milk for around 4 months, mostly during and after a shower. And at the far end of the range: one mother whose breastfeeding never got going with her first child kept losing milk until she was 14 weeks pregnant with her second, so nearly 2 years.
That's how long it can run. The hormones that switched your milk production on come down only gradually after the birth, even if you never feed. Small amounts of milk can keep appearing for a long time because of it, especially with warmth or touch. A shower that frees a few drops, months after giving birth, fits right into that picture.
The one sign where you don't wait it out
For everything above, the message is: this belongs to the range, waiting is fine. There is one exception, and you recognise it by the fluid itself, never by the calendar. Milky fluid from both breasts that moves with your rhythm, more with a full breast and less after a feed, fits the normal range. However long it carries on.
Do get it assessed by a doctor or a lactation consultant if:
- the fluid keeps coming from only one breast, especially if it seems to come from the same spot every time;
- it's bloody and hasn't cleared on its own after a few days;
- it doesn't look like milk, or smells odd and unpleasant;
- long after your last feed or the birth it isn't gradually easing but increasing, or starts up out of nowhere;
- there's a lump or hard patch with it that doesn't shift, or pain and redness come with it;
- you develop a fever or feel fluey alongside a breast complaint. Ring your GP then, because that can point to mastitis.
For everyday questions about leaking and feeding, your health visitor or a lactation consultant is the place to start, and in the first weeks after the birth your midwife. For anything medical, ring your GP, or NHS 111 out of hours. If you're in doubt, have it looked at once too often rather than once too little. Above all, hold on to the core of it: the duration alone is never the alarm signal.
What you wear while your number runs its course
Nobody can give you an end date, and speeding it up isn't possible either: the leaking fades on its own once your body is ready. What you can do is make sure the in-between time doesn't run your day. Loose breast pads only half manage that: they shift, roll up and slide away at night, precisely at the moments the leaking is at its heaviest.
That's why our nursing bra catches the leaking in the cup itself. Four layers that wick moisture away from your skin, hold up to 30 ml per cup and protect your top, with no loose part that can shift. Wireless, with a clip that opens one-handed, so just as useful in week 6 as in month 9. Whether your range turns out short or long: see the nursing bra.
Frequently asked questions
I'm still leaking at 6 months. Am I the exception?
No. The range mothers themselves report runs from about 6 weeks to well past 9 months, and a small group leaks for as long as they feed. If you sit at the long end, your let-down reflex is simply a little more generous. That's variation, not a fault. Only watch the fluid itself: one-sided, bloody or odd-smelling fluid is worth getting assessed.
My supply regulated ages ago. Why am I still leaking?
Because regulating and leaking are two different things. Regulating means your production is matched to what your baby drinks. Leaking comes from the let-down reflex that makes your milk flow, and that reflex can stay sensitive for months, especially on the other side during a feed. Plenty of mothers still leak while their amounts have been right for weeks.
Why do I still wake up wet at night when I'm dry all day?
At night you get the longest stretch between two feeds, certainly once your baby starts sleeping through. Your breasts fill fuller than in the daytime and overflow more easily. Day and night each have their own timeline: many mothers are dry by day months before they're dry at night. That's the normal, slower night pattern.
I'm not breastfeeding. How long will I keep leaking?
Even without feeding, it can take weeks to months before the last of the milk stops. The hormones that switched your production on come down gradually, and warmth, such as a shower, can free a few drops for a long time. On forums mothers report everything from 4 weeks to many months. If the fluid is increasing or looks abnormal, get it checked.
When should I see a doctor about leaking?
Never because of the duration alone. Do go if fluid keeps coming from one breast, is bloody, doesn't look like milk or smells odd, if it starts up out of nowhere or keeps increasing long after your last feed, if there's a lump or hard patch that doesn't shift, or if a fever comes with a breast complaint. Ring your GP then, or put it to a lactation consultant. Milky fluid from both breasts that moves with your rhythm is no cause for concern.
