BabyMotion Flange – The Soft Flange That Mimics Your Baby’s Natural Suckling

Q: How to use the BabyMotion Flange?

The flange is used like any regular breast pump flange. Because it is soft, it can absorb some vacuum, so you may need to turn your pump up a little bit. When using, insert it tightly into the connector with a twisting motion to ensure a good seal.

Q: Which breast pumps are the BabyMotion Flange compatible with?

The BabyMotion Flange is directly compatible (no adapters needed) with Medela, Lansinoh, and Hygeia pumps. To use it with Spectra or Motif pumps, follow our Spectra and Motif hack instructions. There are also hacks available for Willow, Freemie cups, Spectra cups, and Baby Buddha pumps by using the recommended components or adapters.

Q: How to use the BabyMotion Flange with Spectra pumps?

We usually recommend getting a Maymom Spectra adapter for use with Spectra pumps. This helps connect the BabyMotion Flange securely while maintaining efficient suction.

Q: What sizes of BabyMotion Flange are available?

The BabyMotion Flange is currently available in six sizes: 12mm, 15mm, 18mm, 21mm, 24mm, and 27mm.

Q: What size of BabyMotion Flange should I get?

Sizing for BabyMotion is different from regular plastic flanges, so sizes from other brands are not directly comparable. Measure your nipple size before pumping using a nipple ruler or caliper and then refer to our sizing guide: 10–12mm nipple size uses 12mm, 13–15mm uses 15mm, 16–18mm uses 18mm, 19–21mm uses 21mm, 22–24mm uses 24mm, and 25–27mm uses 27mm. If you have questions, you can always contact us via the chat box on our website.

Q: Why is the BabyMotion Flange so heavy?

The flange is intentionally heavier to ensure that pumping efficiency is not compromised when using a soft silicone material. Because of its weight, we recommend disconnecting the flange from the bottle first when you are done pumping to prevent tipping and losing breast milk, and using a well-fitting pumping bra for extra support.

Q: How to clean the BabyMotion Flange?

Before first use, wash the flange with warm soapy water and steam it for about 3 minutes to sterilize. After that, wash with warm soapy water and let it air dry. Occasional steaming is fine, but we do not recommend frequent steaming as it may cause discoloration over time.

Q: Why does my BabyMotion Flange fall off the connector?

If the flange falls off the connector, it is usually because it was not inserted tightly enough or there is residual milk or oil on the parts. Use a twisting motion to push the flange fully into the connector and make sure both parts are thoroughly washed with warm soapy water or baking soda to remove any residue.

Q: Can I place my BabyMotion Flange in the fridge between pumps?

We do not recommend storing BabyMotion Flanges in the fridge between pumping sessions. When they come out cold, moisture can condense on the silicone, making it slippery and more likely to slip off the connector.

Q: Can I use coconut oil or other lubricants with the BabyMotion Flange?

Yes, you can use coconut oil or other lubricants with the BabyMotion Flange. Just be sure to wash the oil or lubricant off thoroughly with warm soapy water after each pumping session to keep the flange and connector clean.

Questions Moms Ask About Pumping Comfort & Elastic Nipples

What’s the biggest reason moms switch to BabyMotion?

Comfort. Moms choose BabyMotion when they want a flange that feels softer, more natural, and closer to baby’s movement— especially when dealing with pain, elastic nipples, or deep pulling.

Can I use BabyMotion if I have sensitive or damaged nipples?

Yes. The soft silicone is gentle on swollen, tender, or sensitive nipples. Many moms switch to BabyMotion specifically during healing or when experiencing pain from rigid flanges.

Does silicone reduce suction strength?

No — silicone transmits suction very well. Most moms actually start on lower suction because BabyMotion feels more efficient and comfortable than plastic.

How is BabyMotion different from regular hard plastic flanges?

Traditional flanges are rigid and pull in a straight line. BabyMotion is designed to mimic elements of a baby’s natural suckling — it flexes gently with each pump cycle, cushions the nipple base, and feels softer on sensitive tissue.

Why does pumping hurt even when I’m using the right flange size?

Many moms still feel pain because most pump flanges are made of hard plastic, which pulls the nipple straight into a rigid tunnel. This can pinch the nipple base, compress the areola, and cause friction. BabyMotion is made of ultra-soft silicone that flexes with your breast tissue, reducing that harsh pulling and making pumping feel much gentler.

What exactly are “elastic nipples,” and does BabyMotion help with them?

Elastic nipples stretch more than average under suction. This can make the nipple pull deep into the tunnel, causing pain or swelling. BabyMotion is especially helpful for elastic nipples because the soft silicone supports the nipple base, reducing deep pulling and making suction feel more controlled and comfortable.

My nipple gets pulled all the way to the end of the tunnel. Will these help?

Yes — that’s one of the most common reasons moms choose BabyMotion. The flexible silicone distributes suction more evenly, which can help prevent the nipple from stretching too far and relieve the pressure at the base.

Will BabyMotion improve my milk output?

Many moms notice improved output once pumping becomes more comfortable. Pain can interrupt letdown and restrict flow. By making suction feel softer and more natural, BabyMotion may help your body relax and release milk more easily.

The Science - why are babies More Effective Than Pumps

During nursing, a baby's tongue stimulates the nipple and compresses the areola. These motions, combined with suction, maximizes milk expression. These are the motions we achieved with the BabyMotion Flange's unique design so that pumping can feel more natural, like nursing.

To use with Spectra or Motif pumps, please refer to this Spectra and Motif Hack. To use with Willow pump, please refer to this Willow Hack. To use with Freemie cups, please refer to this Freemie Hack. To use with Spectra cups, please refer to this Spectra Cup Hack. You can also use it with Baby Buddha pump by following the component hacks.

How to use the BabyMotion Flange with Spectra pumps?

We usually recommend getting the Maymom Spectra Adapter for use with Spectra pumps.

What sizes of BabyMotion Flange are available?

We currently offer 12mm, 15mm, 18mm, 21mm , 24mm, and 27mm.

What size of BabyMotion Flange should I get?

Please note that the BabyMotion Flange has a different design than regular plastic flanges so sizings from different brands are not directly comparable. You can measure your nipple size before pumping using the Nipple Caliper and then refer to the below sizing guide (we suggest before pumping measurements especially if you have elastic nipples). If you have additional questions, please use the chat box on our website.

Pre-pumping Nipple Size ---------->BabyMotion Flange Size

10-12mm ------------------------------->12mm

13-15mm ------------------------------->15mm

16-18mm ------------------------------->18mm

19-21mm ------------------------------->21mm

22-24mm ------------------------------->24mm

25-27mm ------------------------------->27mm

Why is the BabyMotion Flange so heavy?

The flange is heavy because we have to ensure that the breast pump efficiency is not compromised when using a soft material like silicone. Because it's heavy, please make sure to disconnect the flange first once done pumping to prevent bottle from tipping over and losing precious breast milk. We also recommend using a tight fitting pumping bra.

How to clean the BabyMotion Flange?

Before first time use, wash with warm soapy water and steam for 3 minutes to sterilize. Afterwards, simply wash with warm soapy water and air dry. It's ok to sterilize with steam occasionally but we do not recommend frequent steaming as discoloration may occur.

Why does my BabyMotion Flange fall off the connector?

Most likely due to it not being inserted tightly. Please use a twisting motion to insert it all the way into the connector. Please refer to this instruction for more details on how. It could also happen when there is residual milk/oil left on the flange or the connector. We recommend using warm soapy water or baking soda to thoroughly wash both parts.

Can I place my BabyMotion Flange in the fridge between pumps?

No. We don't recommend it because they will be cold and attract moisture once taken out of the fridge, making them slippery and hard to stay on the connector.

Can I use coconut oil or other lubricants with the BabyMotion Flange?

Yes, although we suggest washing the oil/lubricant off with warm soapy water thoroughly after each pumping session.

How often should I replace the BabyMotion Flange?

The BabyMotion Flange should last a few months and only need replacement when you notice cracks or discoloration.

Great flanges and customer service

I followed the sizing guide and it said I would need 18mm. I think i discovered i have elastic nips because the 18mm was huge. But once I started pumping my nips would vacuum to the sides and I wouldnt get much out. I ended up emailing them, and they got back to me in less that 24 hours, on the weekend! They sent me the next size down and now im getting great results! Both times of shipping, I got the flanges so quick! Both within 2 days. So I would 100000% recommend purchasing from this company for the best flanges

Great customer service

I ordered a size based on the guide (it was a the top size though) and it ended up being tight so I contacted customer service and they send me the next size up with their sizing guarantee. They responded I less than 24 hours and I had them within 10 days. They are much more comfortable than the hard flanges.

Better than Pumpinpals

I have elastic nipples and a low supply due to being a NICU mum who delivered at 27+5.

I'm pumping round the clock and these are easily my favorite flanges - and I've tried everything.

I'm going to buy a second pair to have when I go back to work. Yes, they're expensive. But they're also the best.

I don't need lubricant (yet one more thing to cart back and forth from the hospital), they're comfortable, and they empty me much more quickly than pumpin pal silicone flanges, which I reserve for long car drives because it takes twice as much time for me to get the same output.

Honestly love these so much.

I LOVE!

I have elastic nips and these have been a game changer for me! It empties me out in half the time it took before and it doesn’t hurt!

my favorite flange!

I've tried everything from flange inserts to another brand of silicone flanges but by far, these babymotion flanges are my favorite. they're so comfortable and they give me the best output.
having the one free size replacement is great too! it was incredibly easy to reach out to customer support and I got shipped the correct size flange asap.
