Leaking breast milk and staying dry

Leaking is oxytocin doing its work. When your breast gets the signal to release milk, tiny muscle cells around the milk glands squeeze, milk moves towards the nipple, and whatever cannot leave through your baby simply runs out. Your brain releases that oxytocin for your baby, but also for anything it has learned to link with feeding: a cry, a photo, a warm shower, a breast that has been full for a while.

That is why it arrives at moments that have nothing to do with a feed, and why it is heaviest in the weeks when your body is still making milk in stock rather than to order.

Nights are the worst of it for most mothers, for one plain reason: the gap between feeds is longer, so your breasts are fuller when the let-down comes. Sleeping on your front makes it worse, and so does the first stretch of sleep your baby finally gives you.

Two things decide whether you wake up dry. Something absorbent that stays exactly where you put it while you turn over, and support that holds without pressing anywhere, because steady pressure on a full breast is not what you want overnight. A towel on the sheet works. It just is not a plan you want to keep for six months. What to wear in bed sits with the nursing bra and fit guide.

It can start before your baby does. Drops of colostrum in the second half of pregnancy are normal, and so is leaking nothing at all: neither one predicts how much milk you will make.

After the birth, the peak arrives with the milk itself, roughly day two to six. From then it is a slow curve. Supply usually settles to your baby somewhere between six and twelve weeks, and for many mothers the leaking drops off sharply around that point. For others it carries on well past six months, at night or during let-down. There is no schedule you are behind on. The spread is the answer.

Heavy leaking has one trap in it, and almost every forum walks straight into it. Emptying your breasts to stop the leaking tells your body to make more, so the next day is worse. The way out runs the other way round.

First, absorb and catch, because that costs your supply nothing. Second, relieve only enough to take the edge off when a breast is painfully full, not until it is soft. Third, look again if it is not really about catching milk any more: a baby choking on a forceful spray, or breasts that stay full and painful, is a different question with a different answer.

Your body has one button for this, and it does not ask what you are doing. So milk arrives during sex, when you sneeze, in the shower, when you laugh, when someone else's baby cries three tables away. Months after the last feed, a hormone surge can still bring a few drops.

It is normal, it is more common than anyone admits out loud, and the awkwardness is nearly always a first-time thing that fades. Feeding or expressing before an evening you care about helps. So does saying it out loud once, which is usually the end of it. More on how this lands in everyday life sits in the body and daily life guide.

Leaking does not switch off on the day of your last feed. Supply winds down over weeks, and a little fluid can appear now and then for a while after that, sometimes for months if you stopped quickly. That is usually your body finishing what it started.

What does not belong to that picture is discharge that comes from one breast only, that is bloody, or that has an unusual colour or smell, and a hard spot that does not ease. Those are worth a doctor's look, whether you are feeding or long finished. How to wind down without engorgement sits in the transitions guide.
