How to set up your manual breast pump
Check all parts of your pump for damage before every use.
Before handling your pump, wash your hands with soap and water, then dry them.
Make sure that all parts of the pump have been washed and sterilised.
Push the connector rod through the bottom of the diaphragm.
With two hands, gently squeeze the bottom of the diaphragm over the ring in the base of the connector rod. The rod should be securely held by the diaphragm.
Place the diaphragm in the top of the pump body and push the diaphragm edge down around the whole circumference of the pump body to make a good seal.
Pick up the pump body and, from the side, slide the handle onto the body, so that the clips on the top slide onto the top of the connecting rod, and the two clips at the side snap onto the back of the pump body.
The handle should now freely move up and down, and you should see the diaphragm lift up when you press the handle down.
Push the horn onto the body until it's fully engaged and secure. Turn your pump upside down.
Insert the duck-bill valve. Gently squeeze the sides of the valve to make sure it opens.
Screw on a Tommee Tippee® Natural Start® (excluding glass) or Advanced Anti-Colic bottle. Your pump is now ready to use.
Place the assembled pump on a flat surface.
Measure your nipples using the size guide, and if needed, add the correct insert for you, or use the 24mm horn on its own.
If a horn insert is required, push the horn insert into the tunnel of the horn until it locks in securely.
How to use a manual breast pump
Comfortable pumping, at your pace. The Tommee Tippee® manual breast pump is lightweight, portable, and designed for relief and easy expressing, anywhere.It’s compact, cord-free, and completely controlled by you.
Find a comfortable position with your back supported.
Hold the pump handset around the narrow neck of the body. Hold it in whichever hand feels most comfortable. As you use it, you may find it's more comfortable to cup your hand around the bottle.
Place the horn over your breast so that it creates a seal all the way around with your nipple at the centre of the hole. You don't need to cover the whole of your areola or breast with the horn, so don't force it. It should sit comfortably. If it doesn't feel right, relax and reposition.
Keep the pump handset vertical while holding it against your breast.
Gently squeeze the handle and you'll feel the suction.
Release the handle and allow it to return to its resting position. Releasing the handle opens the valve so your milk can flow into the bottle.
Try to imitate the rhythm of your baby as they suck. You don't have to squeeze hard – just as much as is comfortable for you.
When you first start expressing milk, use the pump for 3-5 minutes on each breast. Over time, you will be able to build up to 10-15 minutes on each breast.
You can help stimulate your milk flow by gently stroking and massaging your breast.
The amount of milk you express and the time it takes will vary. Don't worry, this is normal.
If air is getting in around the horn, your pump may not suck milk effectively. Adjust your position and replace the cup on your breast so that it feels comfortable and the pump is expressing milk.
What to expect the first time you pump
When you pump for the first time, think of it as simply getting to know your body in a new way.
In the early days, try spacing your sessions at different times of the day to see when your milk flows most comfortably. It can be helpful to keep a record of times and volumes in the first few weeks, so you can spot what feels most natural for you.
Remember to be kind to yourself, not every session has to focus on volume, it’s also about catching those moments of relief.
How do the massaging petals work?
The soft, petal-shaped silicone cushions integrated into the horn of your Manual Breast Pump flex and massage as you express. These petals are specially designed to mimic the natural way a baby uses their hands to gently massage the breast during feeding. As the petals move, they stimulate breast tissue and encourage let-down, helping your milk flow naturally and effectively.
This thoughtful design not only makes expressing milk more efficient, but also supports your comfort with every session.

How to clean and sterilise a manual breast pump

Unscrew the bottle from the pump body.

Pull the horn away from the pump body and remove the duck-billed valve.

Disconnect the handle from the body by pulling away from the body horizontally.

Lift out the diaphragm from the body.

Pull out the connector rod from the diaphragm.

Wash all parts in clean soapy water. Don't use water that you've used for cleaning other products.

Rinse thoroughly with clean water.

You can also wash the pump components and horn inserts in the top rack of a dishwasher. Place the peach duck-bill valve in the cutlery rack or dishwasher pod to help keep it safe.

Sterilise all parts of the pump and the horn inserts using either cold water sterilisation, microwave sterilisation, boiling water, or electric steam sterilisation.

For best results, use Tommee Tippee® UV, electric or microwave sterilisers.

Do I need to sterilise my breast pump after every use?

Yes, every part that comes into contact with breast milk should be cleaned and sterilised after every use, so the components are clean for your next session. These include the diaphragm, duckbill valve, horn and, if used, inserts.

You’ll also need to sterilise any bottles, teats and storage lids used to feed or store breast milk.

Breast milk storage bags should be disposed of after use as these cannot be cleaned and sterilised.

Manual breast pump comfort and fit

How do you measure for a breast pump?

The right fit for you is based on how your nipple fits into the tunnel of the horn or insert. Use the included nipple measurement guide to help you find your perfect fit:

Measure the diameter of each nipple in millimetres using the nipple measurement guide provided – hold the different cut-out spaces against your nipple to see which size best aligns with you.

Make sure you measure both nipples, because no two are the same.

Once you have measured both nipples choose the horn insert that is closest to your nipple size and then consider experimenting with the size above and the size below.

Remember, every session is different, and your nipples may change size over time. We recommend regularly measuring your nipples and adjust the insert size accordingly.

Tommee Tippee® breast pumps come with more horn inserts than before, making it easier to find your best fit. Additional inserts aid better fit, which in turn reduces leakage and discomfort, supporting a positive breast pumping experience.

Your pump has a 24mm horn and 5 interchangeable inserts in 13mm, 15mm, 17mm, 19mm and 21mm. There’s also a nipple measurement guide included to help you find your perfect fit.

Measure the diameter of each nipple in millimetres using the nipple measurement guide provided.

Make sure you measure both nipples because no two nipples are the same.

Once you have measured both nipples, choose the horn insert that is closest to your nipple size, and then consider experimenting with the size above the size below.

Keep your nipple measurement guide in a safe, convenient spot, so you can easily reach for it as your nipple size changes over time.

You’ll have found your ‘sweet spot’ when you experience the greatest comfort and a consistent milk flow.

If your nipple rubs or feels pinched against the sides of the insert, this may indicate your horn size is too small. We recommend going up a size with the inserts included for a more comfortable fit.

If expressing feels uncomfortable or sore, you may need a smaller insert.

We recommend regularly measuring your nipples as your optimum size may change over time. The inserts can be swapped as little and often as you like. It’s all about what’s most comfortable and effective for you.

How do you know if your manual breast pump fits?

Expressing and pumping breast milk shouldn't hurt, feel uncomfortable or cause breast tenderness. You will have found the right fit when you experience the greatest comfort and a consistent milk flow.

Your whole nipple should fit comfortably without much, if any, of the areola entering the tunnel of your chosen horn or insert before you start pumping.

Your nipple should be centred in the middle and move freely in and out of the tunnel while you pump, without causing rubbing, redness or pain.

After each session, your pump should express most of your milk and your breasts should feel noticeably softer.

Nipple measurement tips to look out for include:

Size is too small: All your nipple rubs against the tunnel and none of your areola gets pulled in.

Size is too big: More of your areola is sucked into the horn and may rub against the edge of the tunnel.

Size just right: While you pump, only a small amount of your areola is pulled into the tunnel, not too much or none.

How do I choose a breast pump?

Frequency of use, function and lifestyle can all contribute towards choosing the right breast pump for you.

Breast Pump	If you are...	Ideal for...	Frequency...
Silicone	Breast feeding and pumping but not a pump	Collecting let-down, engorgement relief, occasional use	Occasional and supplemental use
Manual	Breast feeding and pumping	Quick relief, short pumping sessions, occasional milk expression	Occasional to moderate use
Electric	Exclusively breast pumping	Regular pumping sessions, building supply, exclusive pumping	High frequency and scheduled use
Hybrid	Exclusively or regularly breast pumping	Regular pumping sessions and building supply. Some sessions may involve cords or components.	Regular use, mid-high frequency
Wearable	Breast pumping with a busy lifestyle	Hands-free pumping while multitasking or on-the-go	Mid-frequency or occasional flexible use

How much breast milk should I pump?

The amount of breastmilk you can pump in a day really depends on your stage of breastfeeding, your body, and your baby’s needs. There isn’t one “right” amount, but here’s a practical guide: 

First few days (colostrum): You’ll only get teaspoons at a time, that’s normal and exactly what your baby needs.

By 2–3 weeks: Once your milk comes in, most parents can make anywhere from 24–32 ounces (700–950 ml) per day, if exclusively pumping.

Established supply: On average, most people produce enough to match what their baby takes, roughly 25–30 ounces (750–900 ml) per day for a full-term baby between 1–6 months.

When is the best time to pump when breastfeeding?

The best time to use your pump is completely down to the routine that works best for you – you may find that you produce more milk at certain times a day.

Although there isn’t a one-size-fits-all approach, many parents find they express more milk if they pump during the night or first thing in the morning. You can use the following as a guide:

Mainly breastfeeding and pumping to increase supply: Express 30-60 minutes after breastfeeding your baby or at least one hour before their next feed.

Store breastmilk for later: Express in the morning as milk-producing hormones are more likely to have replenished your supply during the night.

Let your partner do the night feed: Express in the evening so breastmilk is available during the night – better still, this milk will contain sleep-promoting hormones.

Increase milk supply: Express after each daytime feed to help signal to your body to produce more breastmilk.

How many hours should I breast pump?

A breast pumping session can last between 15 and 45 minutes, but every session can vary. It’s important to measure each session on how your breasts feel, rather than the duration. Remember, longer and stronger sessions don’t necessarily mean more breast milk. We recommend working with the setting that feel most comfortable for you.

Signs that you’re coming to the natural end of a session are softer, lighter breasts and a slow-down in breast milk flow.

Is my manual breast pump travel friendly?

Yes, the Tommee Tippee® Manual Breast Pump is compact and handheld. It’s perfect for first-time pumping or as a discreet, portable back-up option if you usually use an electric pump.

The pump is lightweight and silent, meaning you can express at home, on the go or whenever you need quick, convenient relief from engorgement or mastitis.

Can I pump when my breasts are engorged?

Yes, pumping can relieve some pressure if your breasts are too full for your baby to latch. It’s best to express only enough milk to soften the breast, as fully pumping can increase milk supply and make engorgement worse. Instead, holding a warm flannel or hot water bottle (avoiding boiling water) can help to soothe. Hand expression is also a gentle option.

For more information on how to prevent and relieve breast milk engorgement, please visit our Parent-care library.

What can I do if I’m not getting enough milk?

Your breast milk supply may fluctuate over time, but if you notice you’re getting less than what's normal for you, try checking…

The alignment of your nipple: The centre of your nipple should be positioned in the centre of the horn, without much, if any, of your areola entering the tunnel.

Your horn size: The horn should feel comfortable and shouldn't draw in too much of your breast tissue. We recommend measuring the diameter of your nipple, and if the included 24mm horn doesn’t fit comfortably, you can interchange between the 13mm, 15mm, 17mm and 21mm inserts. For more space, you might want to try the 28mm horn, available online via the Tommee Tippee® website via mobile or the app.

How do I store my breast milk after I pump?

Your Manual Breast Pump screws on to a Tommee Tippee® bottle (excluding glass), so you can store your expressed milk straight away. These storage lids are also compatible with Tommee Tippee® Natural Start® Silicone Bottles.

When you’re ready to feed, simply unscrew the storage lid and replace with a sterilised screw ring and teat.

Breast milk storage bags may also come in handy and can be conveniently stored in the fridge or freezer.

Method of storing breast milk	Use within	REMEMBER
Room temperature < 25°C	6 hours	• Never defrost or heat breast milk in a microwave. • Never refreeze breast milk. • Breast milk stored in the fridge but intended for freezing should be frozen within 24 hours. • Once defrosted, breast milk should be kept in the fridge and used within 12 hours. • Do not boil breast milk. • Throw away any leftover breast milk after feeding.
Refrigerated at 5-10 °C	3 days
Refrigerated at 0-4 °C	6 days
Frozen	6 months

NHS guidelines recommend labelling stored breast milk with the date so it can be used within the advised timeframe, helping to avoid waste.

When you want to freeze expressed breast milk, leave some space at the top of your bottle or storage bag for it to expand. It’s easiest to freeze breast milk in individual feed quantities of 2-4oz or 60-125ml.

Thaw frozen breast milk in the fridge or by standing your bottle or storage bag in lukewarm water until it has reached body temperature. Or use a Tommee Tippee® bottle warmer.

Your breast milk may separate out into layers when you store it. Give it a shake to remix it thoroughly before feeding your baby.

If you want to take expressed milk out and about with you, make sure it stays cold or frozen until you need to feed your baby.
