  • Transform pumping to nursing

    Patent Pending

    BabyMotion Flange is developed based on biomechanical studies of nursing babies. It compresses the nipple and areola during pumping to maximize milk expression, like a baby.

  • Benefits

    Mimic Nursing

    BabyMotion Flange transforms pumping into nursing, giving pumping a bit more the human touch.

    Stimulate Let-down

    BabyMotion Flange compresses nipple and areola during pumping, which sends a signal to your brain to stimulate let-down and help release milk.

    Soft and Comfortable

    BabyMotion Flange is soft and non-abrasive, which is way more comfortable than hard plastic flanges.

    Better Seal

    BabyMotion Flange is soft and therefore moves with your breast while you pump to ensure a better seal, which makes breast massaging easier.

    Improved Privacy

    BabyMotion Flange is semi-transparent and protects your privacy even if a family member or co-worker accidentally walks in on you while pumping.

    Wash fewer Parts

    BabyMotion Flange's one-piece design allows you to wash less parts than traditional soft breast shield inserts.

    Potentially Increase Pumping Efficiency

    Research has shown that adding a compression stimuli during pumping increases pumping efficiency.

    Potentially Increase Production

    Research has shown that emptying your milk more during each pumping session will increase your production.

    The baby motion flange is amazing! I get more milk out (2.5 Oz for one session) in less time. I even use it with a manual pump and I'm able to squish it around to mimic a baby sucking! I love that I can fold it back and line it up perfect every time. I highly recommend to everyone!!

    Heather, Middlebury, IN

    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!

    Katie, Marshall, IL

    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.

    Jessica, Forest Hills, NY

    Using the BabyMotion Flange, I pumped 2.5Oz more than usual. I did feel the stimulation and it's very soft and comfortable.

    Desiree, Tampa, FL

    I produced 1.5oz more milk from breast using BabyMotion flange than breast with regular flange. It was also extremely comfortable and soft, it didn’t feel like the same pumping experience. I was shocked by how comfortable the experience was!

    Jennifer, Ames, IA

    Just used for first time and I loved them! My nipples have no pain like normal from my hard plastic flanges and I emptied very fast, I kept pumping my normal 20 minute session but had same output at 10 minutes that I had at 20!

    Emily, Virginia Beach, VA

    By using the BabyMotion Flange and Baby Buddha Pump, I got about 1 ounce more out of each side each pump! It did SO good!

    Jandi, Willowwick, OH

    I received it yesterday and have used it every pump since. I’ve actually noticed I’m getting more output on the side I’m using it on!!

    Nichole, Bay City, MI

    I was able to pump 1.0-1.5oz more in the same amount of time with these over my plastic flanges. Also, they don't hurt, which is awesome when you're pumping your nipples off. A must have for the pumping moms arsenal!

    Regina, Bergholz, OH

    Fellow pumping Moms, I'm really wary of most products out there, but this is a game changer. Yes, I have it. Yes, I use it every day. I don't think I would have made it this far without this flange.

    Joanna, Newland NC

    It was nice and soft and comfortable. A lot more comfortable than the Medela or Spectra flanges. I have bruises on the underside of my boobs from them.

    Elizabeth, Franklin TN

    WOW! These flanges are amazing! They have been a game changer from the first time I used them. I was dropping supply and felt like my pumping journey was slowly coming to an end, but these flanges have helped me increase my supply again! They stay put and feel 100 times better than the hard plastic flanges. They are truly much closer to my baby's natural sucking. I am so impressed and happy! Thank you so much!

    Margaret , Rocklin, CA

    I love my BabyMotion flanges!! I wish I had these for the first 7 months that I was breastfeeding, but better late than never! Not only am I able to pump more, but I can pump more in less time than before!! And they are so much more comfortable than traditional flanges! I have already recommended them to my pregnant sister and my best friend. I honestly can’t think of anything that needs improving. The 2nd Generation improvements are great!

    Sheila, Chelsea, AL

    I love these flanges! They are so much more comfortable than my plastic ones - no pinching or friction at all. They also make it so much easier to massage while pumping because they are so flexible.

    Caitlin, Boston, MA

    I've noticed i empty better since using the lactek flanges, they are more comfortable than the hard plastic ones.

    Heather, Morenci, MI

    I used them for the first time this morning and love them I’ve been exclusively pumping for 5 months and have had with chaffing and with the plastic flanges I just dreaded pumping because it hurt but I was able to pump with the baby motion flags with no pain I love this product

    Andrea, Richmond, MI

    It's so comfortable pumping in comparison to the hard plastic standard ones and works wonders pumping more than normal ones too!

    Sariah, Spokane​, WA

    I stopped responding to my flanges, which is scary for an exclusive pumper, who has tried everything on the market. I came across these flanges and was able to express milk quickly and comfortably, I recommend these flanges to everyone. I am going to order more to keep around at home and work.

    Amy, San Ramon, CA

    I have elastic breast tissue: when I pump my entire nipple swells up to the size of the flange I’m using and most of my areola is sucked into the flange as well. It makes pumping extremely painful. I’ve tried all sorts of remedies - buying larger flange sizes; buying different manufacturer’s flanges; buying different lubricants. I came across LacTeck via Google. I was extremely skeptical and hesitated for a few weeks because I didn’t want to spend another twenty-something dollars on something if it wasn’t going to work! I did end up buying the Baby Motion flanges and the BeauGen cushions. It was amazing! This is the first time I’ve ever pumped without pain! I actually stopped breastfeeding my first baby when my maternity leave ended because I couldn’t stand pumping. I’m currently breastfeeding my second baby and so relieved that nursing can end when we want, and not stop because of the pain of pumping!

  • 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 using a Medela connector and a long-stem backflow protector.

    How to use the BabyMotion Flange with Spectra pumps?

    Please refer to this hack for ways of using BabyMotion Flanges with Spectra pumps.

    What sizes of BabyMotion Flange are available?

    We currently offer 18mm, 21mm , 24mm, and 27mm. We are also working on an 15mm that will be launched in March 2021. If you need other sizes, please feel free to tell us the size you need.

    What size of BabyMotion Flange should I get?

    If you don't have elastic nipples, you can order the same size as your best-fit plastic flanges. If you have elastic nipples, we suggest ordering one size down from your best-fit plastic flanges. Please note that the BabyMotion Flange has a different design than regular plastic flanges so sizing is not directly comparable. If you have additional questions, please email contact@lacteck.com.

    Does the BabyMotion Flange work if I have elastic breast tissue?

    Elastic breast tissue absorbs a lot of vacuum from the pump, which means less vacuum left to make the BabyMotion window on our flanges move like a baby's tongue. However, our soft flanges are still more comfortable than the hard plastic ones if you are just looking for comfort.

    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.

    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 but we do not recommend frequent steaming as slight discoloration may occur. Please download the product instruction for more information.

    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 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 pump.

  • why are babies more effective than pumps

    During nursing, a baby's tongue stimulates the nipple and its jaw compresses the areola. These motions, combined with suction, maximizes milk expression. However, during pumping, a plastic flange applies suction only to the breast, making it less effective.

  • Science of Baby's suckle

    For curious moms like us who want to understand more about the science :)

    Measurement of tongue-artificial nipple contact force in infants with sucking difficulties.

    Subjects were 20 healthy infants (Group A) and 5 infants who had difficulty sucking (Group B). The latter could not breastfeed well and were fed from bottles or tubes. Informed consent was provided by the parents or guardians. The measured maximum force at the tip of the nipple was 1.4 ± 0.4 N and 1.2 ± 0.3 N (mean ± SD) in Groups A and B, respectively. At the base of the nipple, the maximum force recorded was 0.8 ± 0.5 N and 0.3 ± 0.3 N (mean ± SD), respectively, showing a statistically significant difference (p<0.05). The sucking period was 0.6 ± 0.1 s (mean ± SD) in both groups. The difference in time necessary to reach the maximum forces between the sensors at the tip and base was 39.7 ± 28.8 ms (mean ± SD) and 37.2 ± 75.9 ms in Groups A and B, respectively.

    Biomechanics of milk extraction during breast-feeding

    How do infants extract milk during breast-feeding? We have resolved a century-long scientific controversy, whether it is sucking of the milk by subatmospheric pressure or mouthing of the nipple– areola complex to induce a peristaltic-like extraction mechanism. Breast-feeding is a dynamic process, which requires coupling between periodic motions of the infant’s jaws, undulation of the tongue, and the breast milk ejection reflex. The physical mechanisms executed by the infant have been intriguing topics. We used an objective and dynamic analysis of ultrasound (US) movie clips acquired during breast-feeding to explore the tongue dynamic characteristics. Then, we developed a new 3D biophysical model of the breast and lactiferous tubes that enables the mimicking of dynamic characteristics observed in US imaging during breastfeeding, and thereby, exploration of the biomechanical aspects of breast-feeding. We have shown, for the first time to our knowledge, that latch-on to draw the nipple–areola complex into the infant mouth, as well as milk extraction during breast-feeding, require development of time-varying subatmospheric pressures within the infant’s oral cavity. Analysis of the US movies clearly demonstrated that tongue motility during breast-feeding was fairly periodic. The anterior tongue, which is wedged between the nipple–areola complex and the lower lips, moves as a rigid body with the cycling motion of the mandible, while the posterior section of the tongue undulates in a pattern similar to a propagating peristaltic wave, which is essential for swallowing. 5230–5235 | PNAS | April 8, 2014 | vol. 111 | no. 14

    The sample included 1844 mothers. About 62% and 15% of mothers reported pump-related problems and injuries, respectively. The most commonly reported problem was that the pump did not extract enough milk and the most commonly reported injury was sore nipples. Using a battery-operated pump and intending to breastfeed less than 12 months were associated with higher risks of pump-related problems and injury. Learning from a friend to use the pump was associated with lower risk of pump-related problems, and using a manual pump and renting a pump were associated with a higher risk of problems. J Hum Lact. 2014 Feb;30(1):62-72

    It was found that volume milk ejection together with vacuum and compression stimuli was 10-46% more than expressing only with vacuum stimuli. Average values were 40.5% ± 5% for expression only with vacuum stimuli and 59.5% ± 5% for expression with vacuum and compression stimuli.  Breastfeed Med. 2016 Sep;11:370-5.

    This protein, termed FIL (feedback inhibitor of lactation), acts by reversible blockade of constitutive secretion in the mammary epithelial cell. As the inhibitor is synthesized in the same epithelial cells, feedback inhibition is, therefore, an autocrine mechanism. FIL's unusual mechanism of action also influences other aspects of mammary function. Acute disruption of mammary membrane trafficking is associated with downregulation of prolactin receptors and followed by a decrease in epithelial cell differentiation. Thus, in addition to acutely-regulating milk secretion, FIL may induce the adaptation in mammary cell differentiation which acts in vivo to sustain the secretory response to a sustained change in milk removal. In the long term, matching of milk output to demand is achieved by a change in mammary cell number. This developmental response is also local in nature.
