How to use a silicone milk collector (and why mums love them)

If you've ever fed bub on one side and felt the other side leak, you already know the problem. That milk is precious, and a silicone milk collector helps you catch it instead of losing it into a breast pad.

Here's how it works, how to use it and what to ask your midwife or lactation consultant if you're unsure.

What is a silicone milk collector?

It's a soft silicone cup that sits over your breast and holds in place with gentle suction. When you feed on one side, your other breast often lets down too. The collector catches that milk without you needing to do anything.

Used this way it's passive: no motor, no noise and no cords. Many mums use one in the early weeks, when their supply is establishing and they feel full and leaky. Our Silicone Milk Collector & Manual Pump can also be used as a manual pump.

How to use it

1. Wash and dry your hands. Check the collector is clean (see cleaning below).
2. Get comfortable. Sit or lie in your usual feeding position.
3. Squeeze the collector flat, then place it over the breast you're not feeding from, with your nipple centred.
4. Release gently so it holds softly in place. It shouldn't hurt. If it does, release the suction by sliding a finger under the edge.
5. Feed bub as usual. Let down on the other side will drip into the collector.
6. Break the seal and tip the milk into a clean storage container or bag when you're done. Keep the collector upright when you take it off so you don't spill.

Tips from other mums

• Try it for the first morning feed, when you're often fullest.
• Use a nursing bra or a loose top to keep the collector in place.
• Don't leave it on for hours. It's for feeds, not for wearing all day.
• If you're unsure about your supply, speak to your midwife, GP or the Australian Breastfeeding Association helpline before you try to increase it.

Cleaning and storing the milk

Wash the collector in hot, soapy water after each use and let it dry fully. Sterilise it regularly, especially in the early weeks, following the care instructions that come with your product.

For how long collected milk can be kept and how to store it safely, follow the Australian Breastfeeding Association guidelines. Breastmilk storage advice can vary with temperature and bub's age, so it's best to check the current guidance.

Frequently asked questions

Will it affect my supply? Collecting the milk that would otherwise leak shouldn't change how much you make, because your body responds to how much milk is removed from the breast. If you're worried about supply, talk to your midwife or lactation consultant.

Can I use it when I'm not feeding? It's designed for use during a feed. Many mums find it uncomfortable to leave on for long, so use it for short periods.

Is it safe for bub? Make sure it's cleaned and sterilised before each use, and always check the care instructions that come with yours.

How many do I need? One is plenty for most mums. A second means you always have a clean spare while the first is drying.
