People are viewing this right now

With an upgraded double-sealed flange design compared to the normal single-flange ones, this S12 Pro wearable breast pump can snug tighter and closer to your breasts to not only pump more efficiently but also prevent milk leaking effectively.

So soft as a baby’s lips, so collecting as a baby’s mouth, our S12 Pro wearable breast pump give moms that “barely-there” all-around comfort fit, and a spa-level pumping experience.

The upgraded 3 modes (stimulation + expression + mixed) allow you to start pumping from the suckling imitation of your baby for more letdown and less pumping pain. 9 levels for each mode, cater for each breast.

The LED large screen of this wearable breast pump allows for easy reading even at one glimpse at night, along with a cup-motor snap-on reminder sound to not only cut the guesswork of pumping duration but also of milk leaking from theloosemilkcup.

Three signs show that you need a pumping bra rather than any usual bra.

First, your breast pump always moves around.
Second, always leaks.
Third, always very hard to put in or take out the pump from the bra.

Support more to lift up, snug closer to avoid leaking, and stretch large to allow flexible room for fluctuating breast size and your pumps, that’s why the pumping bra is needed for your breast pump, especially our pumping bra! Buy Bundle>

1. Ensure that the breast pump and accessories are installed correctly and that the flange fits the breast when pumping.

2. Select the correct size flange. (15/17/19/21/27mm also available in Momcozy website. Check here).

Some breast pump accessories do need replacing regularly to maintain performance. If you notice that your pump seems to have lost suction, the first thing you should do is take a look at your parts, particularly the valves, and inspect for wear, fraying, or stretching and replace if needed.

1. Diaphragm, duck valves and inserts are recommended to replace your parts every 2-3 months;

2. Flange shields and milk collector need to be replaced every 6 months
