How to prevent breast milk from leaking

A let-down does not check the room first. It fires when your baby cries, when someone else's baby cries, and sometimes when you simply think about feeding.

Breasts leak because the let-down reflex can fire whether or not your baby is on the breast, and a full breast leaks more readily than a soft one. Feed or express on your usual pattern, press the heel of your hand over the nipple when a let-down starts in public, and keep a dry pad against the skin.

Why does breast milk leak?

Two things are going on at once. Your breasts are making more milk than they have learned to hold, and the reflex that releases it is still easily set off.

Oxytocin drives the let-down. It responds to a cry, a warm shower, the sight of your baby's cot or a photo on your phone. The NHS describes leaking between feeds as common in the early weeks for exactly this reason. One breast often drips while your baby feeds from the other, which is normal.

Fullness is the other half. A breast that has gone four hours without a feed is under pressure, and the milk finds the nearest way out.

When does leaking settle down?

Usually within the first couple of months, as your supply adjusts to what your baby actually takes. The reflex gets more selective at the same time, so it stops firing at other people's babies.

Some mothers never leak. Some leak for as long as they feed, and a few only ever leak on one side. None of that predicts how feeding will go.

What stops a let-down mid-meeting?

Pressure, applied straight away. Cross your arms firmly across your chest, or press the heel of a hand over each nipple through your top, and hold for a slow count. The reflex passes.

This only buys time, so feed or express soon afterwards. Milk sitting in a full breast can set up a blocked duct, and our guide to clearing a clogged milk duct is the one you want to avoid needing. If you often feed while out, our tips on breastfeeding in public cover the practical side.

How do you keep clothes dry in this heat?

Breast pads do most of the work, and the climate changes how you use them. Disposable and washable pads are both easy to find at pharmacies and baby shops, and washable cotton or bamboo ones breathe better in humid weather.

Change them as soon as they feel damp. A pad that would last all morning in a cool country lasts a couple of hours here once you have walked across a car park, and the damp is sweat as much as milk. Carry spares in a small zip bag. Keep a dark or patterned top at work, since a print hides a wet patch that a pale blouse shows straight away.

A soft, wire-free nursing bra holds pads in place without pressing on one spot. Our Maternity Nursing Bra has cups that unclip easily for feeds and fabric that absorbs sweat, so it stays comfortable in the Malaysian heat. Avoid anything tight over the breast. A seam or underwire digging into one place can block a duct, which turns a laundry problem into a painful one.

Can damp pads upset your skin?

Yes. Warm, damp fabric keeps nipple skin soft and fragile, and fragile skin cracks more easily. Many mothers learn this the hard way.

Let the skin air for a few minutes when you get home, and change pads often. A crack that has not started to settle within a few days is worth showing to your doctor or a lactation consultant, because the latch is usually behind it.

Pain that burns after feeds, shiny or flaky nipples, or white patches in your baby's mouth that do not wipe away can point to thrush. That needs treatment for both of you, so see a doctor at your klinik kesihatan or GP.

Looking after nipple skin day to day

A balm between feeds stops the skin drying out. Our Intensive Nipple Cream is a rich lanolin balm with shea butter, coconut oil, vitamin E and date fruit extract, with no fragrance or alcohol. It moisturises and protects nipple and areola skin and helps prevent cracked nipples, and there is no need to wipe it off before the next feed. In a Mama's Choice satisfaction survey of 74 mothers in Indonesia (2022), 96% felt dry nipple skin became softer and 92% felt more comfortable while breastfeeding. It is halal certified by BPJPH, Indonesia, and you can find it on Shopee. It contains lanolin, from sheep's wool, so skip it if you react to wool.

Does leaking say anything about your supply?

Very little. Mothers with plenty of milk often stay completely dry, and mothers who soak through two pads can still worry about how much their baby is getting.

Judge supply by your baby. Plenty of heavy wet diapers, steady weight gain recorded in your baby's health book at the klinik kesihatan, and a baby who comes off the breast content are the signs to watch.

What about leaking once you are back at work?

Eligible employees get 98 days of paid maternity leave under the Employment Act 1955, so many mothers go back while they are still feeding. Leaks follow the gaps in your day.

Keep your pumping times roughly even, because a skipped session on a long morning shows up on your shirt by lunch. Our guide to pumping at work covers the schedule, storing milk in the heat and what to ask your employer for.

When should you see a doctor?

A red, hot, painful area on the breast with fever and aches suggests mastitis. The NHS advice is to get seen quickly rather than waiting a day to see if it settles. Your klinik kesihatan, GP or obstetrician can manage it.

Blood from one nipple only, or milk that keeps coming months after you have stopped feeding, is worth a doctor's look too. Both usually have a simple explanation, and a doctor is the right person to find it.

Wash reusable pads with your baby's clothes in a mild detergent, then dry them properly in the sun or a dryer. Pads that go back in the drawer slightly damp are the ones that start skin trouble, and in this humidity they rarely dry well on a bathroom rail.
