We’re sorry you’re having trouble! The mōmi nipple involves quite a bit of complex engineering, and on rare occasions a defective one may slip through our rigorous inspection process.

If you believe your mōmi product may be defective, please stop using it immediately to avoid any potential safety risk to your baby. Then email us the details at care@momi.baby. If possible, attach a photo showing the defect. We’ll work with you from there to replace any defective parts at no cost to you. At our option, we may choose to issue a refund instead of a replacement. We may require that you return the defective part (at our expense).

Here are some potential signs of defects that we’re aware of

• Nipple collapses during feeding. This can be a sign that baby needs a faster flow rate, but may also occur if the vent in the nipple isn’t functioning properly to allow air back into the bottle. A vacuum forms in the bottle, eventually causing the nipple to collapse as if being sucked into the bottle. 
• Milk or formula drips from the anticolic vent. The vent is designed to let air in while preventing liquid from spilling out. If milk is leaking from anywhere except the central duct, please let us know.
• Milk duct is malformed. The narrow milk duct that runs through the nipple’s tip should be straight and centered. A slight angle is normal and should not create any problems. If the duct is significantly off-center or has bubbles or bulged areas, that may indicate a defect.

Small bubbles in the tip of the nipple are normal and don’t cause a problem as long as they’re not connected to the milk duct.

We’ve worked closely with lactation consultants and professionals to develop the mōmi bottle, and we’ve learned a lot about feeding babies on the way. Please check out our blog for helpful tips! (“How to Introduce the mōmi Bottle to a Breastfed Baby” is a great place to start, but you can search all of our feeding content with the “feeding” filter.) It sometimes takes four or five tries (or even more!) for a baby to accept a new bottle. Don’t be discouraged! And we’d love to help you troubleshoot if you run into issues with bottle introduction. Please reach out to us by email at care@momi.baby, by voicemail or text to 980-400-6455, or by chat on our website. We’ll do our very best to respond within 24 hours.

This can happen when warm milk heats the air inside the bottle, causing it to become pressurized. This can happen with most bottle brands.  If this is interfering with feeding, consider not warming the milk to as high a temperature.

Some chewing or gnawing is normal when mōmi is first introduced to your baby, as babies explore the world through their mouths and they’re learning that this is a source of food. Once feeding is established, it’s important not to allow the baby to use the nipple as a pacifier or teething toy. Excessive chewing or gnawing on the nipple can cause it to wear out more quickly and can even create a safety hazard. Please see the specific safety guidelines under the “product safety” section below.

The mōmi bottle’s built-in, patented babypace® technology allows baby to regulate the flow and pace of a feeding like in nursing. No pacing needed! Your baby will be a more active participant with this bottle, which supports their healthy oral development. (Wondering what paced feeding is all about? Here’s everything you need to know.)

We’ve compiled expert advice on washing and sanitizing baby bottles on our blog. 

For extra germ removal, we recommend sterilizing your bottle components (including nipples) daily.

Excessive exposure to UV, such as from a UV sterilizer or direct sunlight, may cause the silicone to decay more rapidly. For this reason, boiling is our preferred method of sterilization.

To sterilize by boiling:
Fill a large, clean pot with enough water to cover the bottle components.

• Submerge the freshly washed bottle in the water upside down, making sure there aren’t any air bubbles at the bottom.
• Bring the water to a boil.
• Set a timer, and boil the bottle for five minutes.
• Turn the heat off and remove the bottle using tongs.

Place it on a clean, dry dishcloth and allow it to air dry.

Note: The Centers for Disease Control and Prevention (CDC) guidelines indicate that daily sterilization may not be necessary for healthy babies older than three months. Since exposure to excessive heat and UV rays can shorten the life of silicone products, you may consider less frequent sterilization if your baby is healthy and older than three months. For more information, read the CDC’s guidance here.

We recommend washing bottle components in hot sudsy water after each use.  mōmi comes with a unique cleaning tool that’s specifically designed to clean the central duct of the mōmi nipple. (Nothing should be inserted in the anticolic vent on the side of the nipple, as this can cause leaks.) Please avoid using other objects to clean the inside of the mōmi nipple as they could potentially damage the soft silicone. Wire or straw-cleaning brushes should never be used to clean your mōmi. To extend the life of your mōmi nipple, soaking is not recommended, as over time this can “cloud” or discolor the silicone.

*If you have other questions about washing, sanitizing and storing baby bottles, our blog has answers. Read “Everything You Need to Know About Cleaning, Sanitizing and Safely Storing Baby Bottles.”

The mōmi babypace® nipple is available in three flow rates.

Important:
Before using the nipple for the first time, clean it with the included cleaning tool, passing the tip of the tool through the opening of the nipple duct 5 - 10 times.  This not only cleans the duct, but also establishes the nipple's correct flow rate.  Watch a brief demo here.

Level 1 is recommended for:

• late pre-term and full-term newborns
• exclusively breastfed babies up to 3 months old who are being introduced to a bottle for the first time (unless they are accustomed to nursing with a strong letdown)
• babies who have established feeding skills with other brands’ level 0 (preemie, etc.)
• The Level 1 flow rate measures 11.3 mL/min with a .03 coefficient of variation (“cv”).

Level 2 is recommended for:

• exclusively breastfed babies older than 3 months
• exclusively breastfed babies under 3 months who have adapted to a heavy let-down
• babies who have established feeding skills with other brands’ level 1 or equivalent (slow flow, etc.)
• babies who have previously adapted to mōmi’s Level 1 and who have graduated to needing a faster flow rate, typically 3 months or older
• Level 2 has a flow rate of 20.8 mL/min with a .04 cv.

Level 3 is recommended for:

• babies who have established feeding skills with other brands’ level 2 or equivalent (medium flow, etc.), typically 6 months or older
• babies who have previously adapted to mōmi’s Level 2 and who have graduated to needing a faster flow rate, typically 6 months or older

Remember that mōmi requires the baby to work for food in a way that most conventional nipples do not, so a baby who has already become accustomed to a conventional nipple may become frustrated if the selected mōmi flow rate is too slow.

Every baby is unique, and sometimes exceptions to these guidelines are appropriate.  We encourage you to work with a lactation support professional if your baby is facing feeding challenges.

Each mōmi nipple is marked with a number near the base, just to the left of the word “naturally”.

Yes, the mōmi bottle can be used to feed breast milk, formula or even a mixture of both (which is even recommended when you first introduce formula). We know that every baby’s feeding journey is different!

• Warm breast milk by placing the container of breast milk into a separate container or pot of warm water for a few minutes or by running warm (not hot) tap water over the container for a few minutes.
• Do not heat breast milk directly on the stove or in the microwave.
• Test the temperature of the breast milk before feeding it to your baby by putting a few drops on your wrist. It should feel warm, not hot.
• Swirl the breast milk to mix the fat, which may have separated.
• If your baby did not finish the bottle, the leftover breast milk can still be used within 2 hours after the baby is finished feeding. After 2 hours, leftover breast milk should be discarded.
• Check out our blog for more expert advice on heating, using and storing breast milk and formula: “How to Safely Store Breast Milk and Formula According to the CDC.”

• You do not need to warm infant formula before feeding. If you do decide to warm the formula, place the bottle with prepared formula under warm running water or into a bowl of warm water for a few minutes.
• Avoid getting water into the bottle or nipple. This could contaminate the prepared formula.
• Test the temperature of the formula before feeding it to your baby by putting a few drops on the inside of your wrist. It should feel warm, not hot.
• Never warm infant formula in a microwave. Microwaving creates hot spots, which can burn your baby’s mouth.
• Read the CDC’s recommendations on safely using and storing formula.

This could indicate a defect. Please contact us by email at care@momi.baby, by voicemail or text to 980-400-6455, or by chat here on our website. If possible, send us a photo of what you’re seeing.

This could indicate that your baby needs a faster flow rate, or in rare cases indicate a defect. Please contact us by email at care@momi.baby, by voicemail or text to 980-400-6455, or by chat here on our website. If possible, send us a photo or video of what you’re seeing.

First, please be sure that you have used your purple cleaning tool in the central duct of the nipple. If you have done this already and there is still no milk flow, it could indicate a defect. Please contact us by email at care@momi.baby, by voicemail or text to 980-400-6455, or by chat here on our website.

mōmi products certified to meet or exceed the U.S. regulatory requirements for infant safety. Even so, failure to follow the safety guidelines can shorten the life of the product, and can potentially result in a safety hazard. The soft silicone used in the mōmi nipple makes it more susceptible to damage when not used properly. Please read carefully and observe the safety instructions included with your product. These include the following:

• Do not use the nipple as a teething toy or pacifier. Using your mōmi nipple only for feeding will allow it to last much longer.
• The soft silicone material is not designed to withstand excessive biting and gnawing.
• Inspect the nipple and all bottle components before each use.
• Discard immediately if the nipple has any signs of damage, puncture, cracking, or tearing.
• Use only the mōmi cleaning tool in the nipple’s central duct, and never use a wire brush to clean the nipple. Wire brushes can damage the soft silicone interior of the nipple, causing a safety hazard.
• Since silicone can break down over time, replace nipples after three months of regular use. 

Other important safety guidelines:

• Sterilize nipple and bottle components before first use. 
• Always check food temperature before feeding.
• To avoid strangulation risk, do not attach cords, laces, or loose clothing to bottle or nipple.
• Always discard any breast milk or formula that remains at the end of a feed.
• Always use this product with adult supervision.
• This is not a toy. Keep all components not in use out of the reach of children.
• Do not allow children to play with small parts or walk/run while using bottles or nipples.
• Remove the bottle from your baby’s mouth when the baby is not feeding.
• Do not let baby take bottle to bed or self-feed for long periods of time.
• Continuous and prolonged sipping of fluids will cause tooth decay.
• Do not place in a heated oven.
• Do not microwave. Liquid inside can heat unevenly or overheat and burn baby’s mouth even if outside of the bottle feels cool.
• When warming breast milk or formula, stir thoroughly to eliminate hot or cold spots, test temperature frequently by placing a few drops on your tongue or back of your hand.
• To prevent possible choking hazard, test strength of nipple regularly by pulling hard on it. Inspect carefully, especially when baby develops teeth, and replace nipple immediately if it shows any sign of wear or damage such as cracking or change of shape.
• Do not leave nipple in direct sunlight or heat or leave in disinfectant (sterilizing solution) for longer than recommended as this may weaken the nipple.
• To ensure the bottle functions correctly and to prevent leakage, make sure all the parts are correctly assembled, remove any debris or residue that may collect around the rim of the bottle before assembly and avoid over-tightening the collar.
• Contact your physician should you have any feeding problems or questions.

Yes, all of our products are BPA free.

Our products are rigorously tested and independently certified for compliance with applicable safety regulations. This includes testing for physical/mechanical strength and chemical content.

Our silicone nipples are made in Canada. Our plastic components are made in the U.S. and China by manufacturers with many years’ experience making baby bottles for some of America’s leading brands. Our glass bottles are made with borosilicate glass by a leading Chinese manufacturer, and have been certified to be lead-free (including the ink) and compliant with U.S. regulatory standards.

Discontinue use immediately and replace with a new nipple.

All silicone products wear out over time. Biting and gnawing, exposure to UV from sunlight or sterilizers, and use of abrasive cleaners are just a few factors that can accelerate the aging of the mōmi nipple. The mōmi nipple is designed to last at least three months under normal use conditions.

If you believe your mōmi nipple has a manufacturing defect, contact us by email at care@momi.baby, by voicemail or text to 980-400-6455, or by chat here on our website. If possible, send us a photo of what you’re seeing.

Discontinue use immediately and replace with a new nipple.

Small bubbles within the solid silicone tip can occur normally in the manufacturing process, and are not a defect. Large bubbles, particularly those that connect with the milk duct, may indicate a manufacturing defect.

We recommend replacing the mōmi nipple after three months of normal use. If a baby with teeth has chewed or gnawed on the nipple excessively, or if the nipple has been exposed to excessive UV radiation such as from sunlight or a sterilizer, more frequent replacement may be necessary.

When it comes to ensuring that babies can transition from breast to bottle in the most seamless way possible, we experimented to identify the most important factor. We discovered that the baby’s ability to control the flow of milk by compressing the nipple with its tongue was the most important factor to be considered in mōmi’s nipple design.

Our nipple is solid with a single duct that allows your baby to stop the flow of milk through compression with the tongue, just as if they were breastfeeding. Hollow nipples can squirt milk out at exactly the time the baby is trying to stop the flow with the tongue, which requires babies to learn a new way of eating in order to drink from a bottle. This can result in nipple preference, bottle refusal, and regurgitation.

The single duct also makes the nipple easier to clean, making it more sanitary for baby and more practical for parents. Hooray!

The mōmi nipple has a vent in the base designed to let air into the bottle during feeding, reducing the amount of air the baby takes in with the food. This is designed to reduce colic.

mōmi is proud to offer a larger bottle size, with a 9 oz option in lead-free glass, or 10 oz in BPA-free plastic.

While mōmi's 5 oz bottles have a wider, bell shape that may not fit into a standard bottle warmer, they work nicely in warmers designed to hold two bottles. Reach out to our care team at care@momi.baby for more specifics!

mōmi's 4 oz and 9/10 oz bottles have a circular base, fitting in conventional single-bottle warmers.

The mōmi nipple and bottle collar are compatible with brand-name and generic standard wide-mouth bottles, including Philips Avent plastic, Chicco Duo, and Maymom, among others. Standard-shaped bottles from these manufacturers can allow you to use your mōmi nipple with a standard bottle warmer. (Please note:  we cannot ensure compatibility of the mōmi nipple with the use of a collar from another brand.)

The mōmi nipple and bottle collar are compatible with brand-name and generic standard wide-mouth bottles, including Philips Avent plastic, Chicco Duo and Maymom, among others.

One cost-effective option we’ve tested is the 9-ounce Maymom Wide-Mouth Milk Storage Collection Bottle with Travel Cap and Sealing Ring, available from Amazon.

Use of the mōmi nipple does require a mōmi collar. Another another brand's collar may result in leaking or inhibit the function of the anticolic vent. If you need the nipple, cleaning tool, collar and clear cap to use mōmi on another bottle, shop our replacement bundles.

The new nipple is longer, and shaped optimally to help babies to achieve a healthy, natural latch. It’s also now soft and stretchy throughout, not just in the tip. We also redesigned the collar and clear cap to fit the new nipple. (See more below on compatibility.)

Yes! Our glass and plastic bottles are both compatible with the new babypace® 2 nipple, used alongside gen 2 collars and clear nipple caps.  The babypace® 2 replacement set, which includes the new nipple, collar, and cap, is a great way to use your gen 1 bottles with the new nipple design.

• bottles: all of our bottles are compatible with both gen 1 and gen 2.
• cleaning tools: gen 1 and gen 2 use the same cleaning tool.
what’s not compatible?
• nipples + collars + clear nipple caps. These are not interchangeable between generations. Attempting to mix these parts between generations can cause problems - like leaks, poor fit, or caps becoming stuck to collars. Think of the nipple + collar + cap as a complete set that can’t be mixed and matched between the two generations.
how do I tell them apart?
• nipples: The babypace® 2 nipple is taller and has a large numerical flow rate indicator molded into the base. The Gen 1 nipple is shorter and has a small “s”, “m” , or “f” flow rate indicator molded into the base.
  
  
  
• caps: The gen 2 clear nipple cap is taller than the gen 1, to fit the taller nipple. [include side by side photos]
• collars: This is the tricky one. There are three ways to tell them apart.
  • The gen 1 collar has a “dimple” in the top surface (concealed by the nipple when it’s attached). The gen 2 collar doesn’t have this dimple.
    
    
  • The notches on the bottom surface of gen 1 are rectangular and spaced further apart than the rounded notches of the gen 2 collar.
    
    
    
• The gen 1 collar has an extra ridge inside where it makes contact with the nipple (highlighted by the arrow in the photo).
• The Gen 2 collar doesn’t have that ridge.
