How do I know if my flange size is correct?

If the flange is too big or too small, it can cause damage to the breast and affect how efficiently you express. Ask a lactation consultant, GP, or child and family health nurse for advice on the correct flange size for you.

Does pumping increase milk supply?

Yes—regular pumping can help maintain or increase milk supply. It can also help your milk come in during the first few days after birth, particularly with a hospital-grade pump.

Is a double breast pump worth it?

If you need to express frequently, yes—double pumps express both breasts simultaneously, making the process much faster than a single pump. They do cost more, but the time saving is significant for regular pumpers.

Why am I not getting much milk when pumping?

Flange size is one of the most common reasons—if it's too big or too small, it affects milk flow. Also check your pump's suction level, which should be between 250-300mmHg for effective milk removal and proper breast drainage.

How do I clean and sterilise a breast pump?

After every use, disassemble all parts that come into contact with milk and wash thoroughly. For sterilising guidance, see our article on how to sterilise baby bottles as the same principles apply.

Choosing the Best Breast Pump: Wearable, Electric and More

Many breastfeeding mums will need to use a breast pump at some stage. But choosing one can feel confusing when you’ve already got a new baby to look after. Should you get electric or manual? A single or double pump? And does it need to be wearable or not?

To make things easier, here’s exactly what you need to consider and how to choose the best breast pump that works for your needs.

What is a breast pump and do I need one?

A breast pump is a device that removes milk from your breasts. The pump creates suction that pulls and releases your nipple like a baby would. This makes your milk flow.

“Breast pumps are important because they give mums the flexibility to offer their baby breast milk when they aren’t available to breastfeed,” says Amy. “This can help in so many situations: if a partner or caregiver wants to take an active role in feeding; if a mum wants to return to work and ensure her baby is still getting the nutrients from breastmilk, or if a baby is struggling to feed.” Reasons to use a breast pump include:

Maintaining or increasing milk supply
Helping relieve engorged breasts or mastitis – always see your GP if you think you have mastitis
Helping your milk to come in when your baby is born
If your baby is premature or ill and can’t breastfeed
If you aren’t with your baby for every feed
If you are returning to work
If there is a chance you will be drinking alcohol and wish to express milk prior for a feed for your baby
If you want a supply of breast milk in the freezer for emergencies.

What to consider when choosing a breast pump:

Flexibility - hands-free pumps let you pump on the move, manual pumps work without power (great for travel), and electric pumps offer convenience at home.
Suction strength - look for 250-300mmHg suction level to ensure effective milk removal and proper breast drainage.
Time commitment - double pumps are faster than single pumps (which require pumping each breast separately) but cost more.
Budget - manual and single pumps are cheaper options, while electric and double pumps are pricier but more convenient.
Lifestyle - frequent pumpers benefit from electric/double pumps, occasional users might prefer manual/single options.

Your guide to breast pumps

All breast pumps have a silicon suction cup (also known as a flange) that fits over your nipple, as well as a funnel and a collection bottle.

“No matter what sort of pump you choose, one of the most important things is to look at the flange size,” says Monique. “If you’re using a flange that’s too big or too small, this can cause damage to the breast.” The correct size will also help you express milk as efficiently as possible. You can ask a lactation consultant, GP or a child and family health nurse for advice on the correct flange size for you. Here are the different types of breast pumps to choose from:

Manual breast pump

How it works: Manual breast pumps rely on you to squeeze a lever by hand to express the milk. Some manual pumps work by suction. They aren’t as strong or quick as an electric pump.

Who it’s best for: It works well for mums who express occasionally, or if you don’t have easy access to a power point when you need to pump.

Need-to-know info: The cheapest and quietest option. They are often small in size, making them convenient and easy to pop in your bag. Only available in single pump options.

Electric breast pump

How it works: Electric breast pumps use motors. These connect to the flanges, and create suction so your milk is released.

Who it’s best for: They’re great for if you have the ability to pump at home, and if you need to express frequently, as they’re much quicker than a manual pump. They come in single and double pump options.

Need-to-know info: Most electric breast pumps have several cables attached, which can make it tricky to move around while you’re pumping. They are generally more expensive than manual pumps.

Wearable breast pump

How it works: Designed to be lightweight and portable, these are worn inside your bra. They usually run off a battery-powered motor, with the collection cups sitting outside your bra. As with electric pumps, the motor creates suction on your nipple to release milk.

Who it’s best for: These are great for mums who are on the go or want a portable option. They are stronger than manual pumps and can have the same strength motor as electric pumps. They come in both single and double pump options.

Need-to-know info: Wearable breast pumps are usually the most expensive option.

Hospital-grade breast pump

How it works: Hospital-grade pumps have a stronger motor than most electric pumps, allowing you to express as efficiently as possible.

Who it’s best for: Mums who need to help their milk come in during the first few days after birth, and mums who have premature babies who can’t feed on their own yet.

Need-to-know info: You may not need a hospital-grade breast pump for the long-term, so they’re available to hire in some states as a more cost-effective option.

You got this

Whatever pump you choose, remember that you're doing an incredible job - even on the days when everything feels hard and you're running on no sleep. Be gentle with yourself as you figure out what works and know that it's okay to change your mind or try something different if your first choice isn't quite right.
