Q: Can I breastfeed on one side and pump on the other?

A: Yes. The all-in-one design of the Wearable Breast Pump makes it so you can pump while you breastfeed your baby because there are no external cords, tubes, or dangling bottles to get in the way.

Q: Can I move around while I pump?

A: Absolutely! The Wearable Breast Pump lets you move how you want to while you pump. The Wearable Breast Pump tucks into your bra so you can pump while you walk, multi-task, lean back, or relax. This makes everyday things like making breakfast or playing with your toddler totally doable. What you do while you pump is finally up to you.

Q: Can I adjust the suction?

A: You sure can. The Wearable Breast Pump has different suction levels(the S9/S10 has five different suction/the S12 has night different suction) so you can easily adjust the suction to your own milk flow and pumping needs.

Q: How do I adjust the breast pump suction level to a suitable one?

A: To find the right level for you, enhance the breast pump suction level gradually until it becomes slightly uncomfortable, and then turn it down a notch.

Q: How to sterilize breast pump accessories?

A: **PLEASE NOTE** heat sterilizing or placing Momcozy washable parts in the dishwasher is not recommended. This will warp and damage the pieces. Consider cold sterilizing and wash with warm water and soap between pump sessions

Q: How long should I replace breast pump accessories?

A: 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.

Q: How to measure my breast pump flange size?

A: At Momcozy, we provide a breast pump flange size chart for you. You can find the correct size through the chart. 

Q: Does the breast pump automatically shut down?

A: The S9 breast pump will automatically turn off after 20 minutes of use, and you can choose to turn it on again to continue using it. It can be used for 70-80 minutes after fully charged, of course it depends on the level you set. 

The S12 breast pump will automatically turn off after 30 minutes

Q: Leak?

A: First of all, check whether the sitting posture is correct. The correct sucking posture is to sit sucking, lean forward 45 degrees, and keep the container upright after sucking. In addition, parts are also recommended to be replaced within 1 to 2 months.

Here’s how to troubleshoot Momcozy’s leak problems:

(1) Leaking from silicone:

If the leak is coming from the edge of the silicone, your silicone might not be snapped in all the way. It’s also possible that your silicone is faulty or warped. **PLEASE NOTE** heat sterilizing or placing Momcozy washable parts in the dishwasher or microwave oven are not recommended.

(2) Leaking from motor or collection cup:

If the leak is coming from between the motor and collection cup, it’s possible that the collection cup and/or motor aren’t fully secured. Another possibility is that the collection cup is cracked and the pressure from the suction is overflowing through the crack.

The solution, keep the correct posture, and then stick it with tape

(3) Leaking from the milk pour hole:

If the leak is coming from the pour hole, make sure the silicone shield notch and the collection cup notch are aligned when snapping the pieces together. If the holes aren’t aligned, leaking is likely through the hole(s).

(4) Leaking from flange hole:

If the leak is coming from the flange hole, it could be caused by leaning back too far. It’s also possible that your duckbill needs to be replaced if the slit is opened and allowing milk to travel back up, and into the flange during strong movements.

Other tips

take out the pump: Tilt it forward 45 degrees and take it out. If it is a nursing bra, it is best to untie the detachable clip. When there is enough space to take it out, it will not touch the silicone flange.

Q: No suciton?

A: If you are experiencing low suction, first check the valves and membranes: Separate the membranes from the valves. Inspect the valves and membranes for damage, including cracks, chips, holes, or tears, and make sure the pieces fit snugly and lie flat. If a part is damaged, discontinue use and purchase a replacement.

Q: Pain?

A: About this problem, The first step is to check whether the flange size is appropriate. If the flange is too large or too small, it will cause pain.

Q: How do I know what bra size I am?

A: Your body’s shape and size can change rapidly during pregnancy and nursing. Each Momcozy product features a size chart to help you get the right fit, and our How to Size Guide Page is also a great resource. For bras, we highly recommend measuring your underbust and bust before ordering. If you need additional fit assistance, send us a message at support@momcozy.com.

Q: How do I know if the bra fits me well?

A: There are several things to look for in determining a good fit:

-The bottom band should sit straight across the back. If the band rides up, check that the straps are a proper length. If the straps are fine, tighten the band or try a smaller band size.

-The bottom band should be snug, but comfortable. You should be able to run two fingers underneath the band. If you can fit more than two fingers, tighten the band or try a smaller band size.

-There should be no puckering in the cups. If there is extra fabric around the cups, try a cup size smaller.

-The breasts should not spill out of the cups or the sides. If the cups cut into the breasts, bulge at the top of the cups or spill at the sides, try a larger cup size.

-The shoulder straps should sit comfortably at the shoulder. Straps should be slipping off, nor digging into the shoulder.

Q: Do all of your products fit the same?

A: Our bras are unique in sizing, so it is strongly recommended that you check each size chart before you make a purchase. Because we work with a variety of fabrics and silhouettes, each style has a different level of stretch and fit. Though you may be a medium in one style, it’s possible that you may be a small or large in another style, so please size yourself accordingly.

Q: How does my size change from pregnancy to nursing?

A: It’s likely that your band size will decrease after delivery to closer to what you were pre-pregnancy. At the same time, your cup size will likely increase one to two cup sizes once your milk comes in. Your breasts will continue to fluctuate in size as they alternate between filling up with milk and breastfeeding. Our bras-sized (small, medium, large, etc.) are designed to stretch to accommodate these fluctuations in your breasts.

Q: Should I size myself even though I’m pregnant?

A: Absolutely! You should size yourself for a new bra when you’re pregnant, especially if you’re in any discomfort. Your body goes through a lot of changes when you’re pregnant and eventually, you’ll outgrow your regular bras. Our bras-sized (small, medium, large, etc.) are designed to stretch to accommodate the breast, rib, and belly growth during pregnancy.

Q: What is the difference between maternity bras and nursing bras?

A: Simply put, the main difference between maternity bras and nursing bras is that nursing bras provide easy breast access for breastfeeding, which may come in the form of drop-down or pull-away cups. Our nursing bras can be worn for both pregnancy and breastfeeding because they are designed with stretch in mind to accommodate the changes in the breasts and rib cage.

Q: When do I need to buy a nursing bra?

A: The best time to buy a nursing bra is anytime you start to feel discomfort from your regular bra, or when you are preparing to breastfeed. This is especially true during pregnancy as your body experiences many changes, as early as the second trimester, which means you will eventually outgrow your regular bras.

Q: How do I wash and care for my bras?

A: To ensure your bras last for as long as possible, follow these steps when washing them:

1. To prevent twisting and tangling, close all hooks and clasps before washing

2. Wash with like colors – for example, beiges with whites and darks with blacks – to keep the colors true

3. We recommend handwashing in cold water. However, if you are using the washing machine, place your bras in a lingerie bag. To reduce fading and shrinkage, choose the delicate cycle and cold water

4. Avoid bleach as it causes fabrics to lose their stretch. If you really must use bleach, choose non-chlorine bleach.

5. To dry, hang it with the cups reshaped and the back hooked up. Avoid the dryer if possible, as dryer heat may damage the stretch

6. Please don’t iron your bra! The heat damages the elastic and changes the fit
