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.

FAQ

How to use the BabyMotion Flange?

The flange is used as any regular breast pump flange. However, because it's soft, it will "absorb" some vacuum so you may need to turn your pump up a little bit. When using, please insert tightly into the connector to ensure a good seal.

Which breast pumps are the BabyMotion Flange compatible with?

The flange is directly compatible (no adapters needed) with Medela, Lansinoh, and Hygeia pumps.

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.

QHow 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.

Wow! If you dont need special sizes, these are a great price for nearly the same as the 4th gen - theyre too big but work with my very thin momcozy inserts (all other ones stop the baby motion from happening, but the very thin frosted silicone of the momcozy brand will still allow for the movement)

Works well

It works well and is comfortable.

Amazing!!! Will be recommending to all pumping moms!

I've been exclusively pumping for 4 months now and these seriously saved my pumping journey. I was about ready to call it quits because every flange I tried no matter what size just didnt work with my elastic nipples, but I decided to give these a try based on the review from somone in my mom group and I'm so glad I did! I feel like because of these I'll be able to make it another 8 months.

Hi Julie, thank you for leaving your feedback and great to hear that these saved your pumping journey! Kudos to making it to 8 months - it's an achievement!

So I've been using these flanges exclusively for about 4 weeks now. Ladies, these are amazing. I didn't have time to wash them yesterday and had to use my spectra flanges.. I average about 16oz per pump with the silicone flanges and I got less than 12 oz with my spectra. I'm at 18 oz this morning and still going so I'm pretty sure my spectra flanges did not empty me well at all. I'm a believer!! Totally worth trying!

After using the flanges for two weeks, I would highly recommend them to any pumping mother. The BabyMotion Flanges cause minimal discomfort while pumping (much less than the rigid plastic flanges) and leave no pain after pumping, which is impressive since I am now turning up the pump to a much higher suction level than I used to when I only used the plastic flanges. On average, I am pumping 0.75-1 oz more per day with these flanges. Some days the difference is as big as 2-3oz. Since the material is heavy, make sure to detach the flanges once you're finished pumping so that the milk-filled bottle doesn't tip over.
