TRANSFORM PUMPING TO NURSING

Our patented 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.

Frequently Asked Questions

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?

Which breast pumps are the BabyMotion Flange compatible with?
The BabyMotion Flange is directly compatible with all Medela pumps except the Freestyle Hands-free pump. It is also directly compatible with Lansinoh pumps. They can also be hacked to use other 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 12mm, 15mm, 18mm, 21mm , 24mm, and 27mm. If you need other sizes, please feel free to tell us the size you need and we will think about making them available in the future.

What size of BabyMotion Flange should I get?

Please note that the BabyMotion Flange has a different design than regular plastic flanges so sizing is not directly comparable. You can measure your nipple size first using this guide 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 email contact@lacteck.com.

 

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 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 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 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

Maternal and Breast Pump Factors Associated with Breast Pump Problems and Injuries
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.

The Mechanics of Breast Pumping: Compression Stimuli Increased Milk Ejection.
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.

Feedback Control of Milk Secretion from Milk
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.
