Kiwy Miya Breastpump FAQs

Kiwy Miya Hospital Grade breast-pump is designed with a closed system pumping action, this ensures that the breastmilk extracted is not exposed to any potential bacteria/germs.


A 12-months warranty is provided on these Omababy’s electrical product: Kiwy Miya Breast pump motor unit from the date of purchase. 

The expression parts are not under warranty and should be replaced as needed.  The soft silicone shield and diaphragm should be replaced at the first signs of weakening (we recommend every 3 months depending on the amount of use and the condition after cleaning and sterilising).

Cleaning of Breast-pump parts

Sterilise all parts prior to first use and after each use except tubing, pump motor and power adaptor. Sterilise all parts that might come in contact with your breastmilk, including bottles, breastshields, valves, backflow protectors, bottle necks, sealing discs, caps and teats with warm soapy water.

Rinse thoroughly, then sterilise and dry. The parts must be totally dry before assembling to pump.  

All of our accessories are suitable for use in UV & steam sterilisers. However please note that it is not recommended to sterilise the accessories under high heat for long hours as it might cause the material to degenerate quicker, shortening the lifespan of the parts.

** All Kiwy Miya components (duckbill valve, 3-way tripod connector, diaphragm, silicone breast shield, tubing, backflow protectors, sealing discs and caps) are not suitable for high heat sterilization such as microwave sterilizer and dishwasher as this will damage the components/accessories. ** 

Do not use any implements or cloths when washing the breast pump parts, as they may tear the delicate silicone parts.

Any damage caused by improper cleaning and maintenance method will void the warranty.  

Please Note:

  • Avoiding getting tubing wet as moisture can cause damage to the pump motor. It can also cause bacteria/mould to grow inside of your pump
  • If the tubes are sterilised, please ensure no water at all is left in the tubes when it is connected to the pump. 
  • If you are using the boiling method, please only allow pump parts to sit in boiling water for 5 minutes as anytime longer than this can damage the accessories. Allow parts to cool before next use.
  • Please allow a maximum of 10 minutes drying time with UV sterilisers as over-sterilisation can damage the pump accessories.

N.B. The tubing and connectors do not come in contact with the milk so they DO NOT need to be sterilised. The tubes can be stored in a dust-free area in a container or a bag to keep them clean. 

Caring for the battery: 

The lithium battery should be kept at room temperature between 20-25 degrees and should never be subjected to elevated temperatures. Please do not leave the battery in or charged the breast pump in a hot car/ hot environment as heat reduces the lithium-ion battery life. 

Batteries deteriorate over time whether they are being used or not. It is best to charge the pump after every use to preserve the battery life and do not allow the battery to goes completely flat. 

Kiwy Miya Breast-pump Modes: 

The breast pump has 2 modes: Automatic and Manual. It is recommended to run the breast pump in the automatic mode unless you wish to have more control over your pumping strength and speed.

The breast pump has 2 pumping mode: Stimulation and Expression Mode. Stimulation mode operates at lower settings and is usually used for massaging the breast to stimulate milk flow. Expression mode operates at higher settings and is the main mode used for expressing breast milk. Always start with both frequency and suction strength low then build up the strength slowly when on expression mode. 

Kiwy Miya Breast-pump comes with 6-Suction Vacuum Level and 9-Speed Level.

Our Kiwy Miya also allows you to adjust different settings separately on your left and right breast to ensure maximum milk extraction and to prevent breast engorgements. 

When should I change the breast-pump parts?

It is recommended that all silicone parts including duck valve are replaced every 3 months or more often if these parts are frequently being sterilised or you are exclusively expressing. This is to ensure you can still have maximum milk extraction as this can affect the efficiency of milk extraction.  

Each Kiwy Miya Breast pump comes with a replacement duck valve, once you noticed that milk yield is less effective, please replace duck valve immediately.

The Kiwy Miya Hospital Grade Breast-pump is hospital-grade and this ensures you of its power, efficiency and durability. It is a smart little gadget that provides more advanced pumping features and more comfortable silicone on the breast, allowing powerful yet comfortable pumping. It has exceptional stimulation and expression levels to choose from, all safe with consideration for the mother's comfort.

To properly maintain your Kiwy Miya,  you’ll need to replace parts on a regular basis. Not replacing parts will make your pump work harder, leading to unnecessary wear and tear on the motor.

● Diaphragm: Replace every 2 - 3 months, or when you notice any damage or decrease in suction

● Duck Valve: Replace every 2 - 3 months, or when you notice any damage or decrease in suction 

● Breastshield/ Flange: Replace every 6 months, or when you notice any damage or decrease in suction 

● Tubing: Replace should moisture ever enter the tubing or when you notice any damage 

Why do I feel pain when I use the breast pump?

Experiencing pain whilst breast-pumping is certainly not what we want, There are many reasons why you may experience pain while expressing, such as: 

Suction Level
The suction on the pump may be too high, please adjust the suction settings for a lower suction strength.

Cracked and sore Nipples
Your nipples may be cracked and is sore due to breastfeeding. If this is the case, stop using the breast pump for a while until your nipples have recovered. 

N.B. If there is any soreness when pumping, please reduce the settings. Please apply some breast milk or nipple cream on the nipple and areola if there is pinching so that the breast does not stick to the silicone and cause further pain and bleeding. 

Flange Sizes

Kiwy Miya comes with one size only flange (22mm) and comes with complimentary silicone shield in order to provide maximum comfort during your pumping sessions.

The size of the shield's nipple area should be bigger than the nipple diameter.  Always centre the nipple shield with your nipple in the middle where it is able to move freely so your milk-ducts don't get blocked.

The areola should be mostly supported by the shield, but if is also fine if some are drawn into the nipple area.  If it is comfortable and the milk is expressing, this is a good sign.
Flange Sizing Guide 
The Kiwy Miya comes with size 22mm Flange size. This is the most commonly fitted size; however, many women will fit better in other sizes. Other flange sizes are available for purchase from here. 
A properly sized flange size is important to ensure the best performance of your pump. An improperly fitted flange size can cause discomfort, hinder milk output, and in severe cases cause injury.
To determine the flange size you need, pump for 5 minutes using the provided shields. Your nipples will expand while milk is being expressed so it’s important to measure after they have swollen to ensure the size you select will provide enough room. After you pump, measure the diameter of the nipples at the base as illustrated in the image to the right. Repeat the process a few times to make sure you have the right measurement. Select a flange size that is 2-3mm larger than this measurement.
Signs that your flange might be too small 
  • General discomfort while pumping
  • Painful rubbing of nipple in flange
  •  Nipple not moving freely inside of flange 
  • Redness of the nipple
  • Whiteness of the nipple and/or a white ring around the base of the nipple
  • Little milk is being expressed
Signs that your flange might be too big
  • General discomfort while pumping
  • Nipple is pulled to the end of the flange
  • Little milk is being expressed
