Mimijumi vs Comotomo Bottles

Both of these bottles are loved by parents and this is mainly due to the fact that they mimic a breast so well. 

The two bottles may look different but they do share some very similar features from the material used for the nipple to their size and feel.

These features make them feel very close to a mother’s breast. But because they appear so similar it can be difficult to choose the right one for your baby.

Despite their similarities, they also have some key differences, which is why one brand is preferred over the other by babies and parents alike.

Mimijumi Bottle Review

mimijumi Very Hungry with FR-2 Nipple

Key Product Features


Mimijumi bottles are made from high-quality Swiss nylon. This makes them far firmer than pure silicone bottles and as durable as plastic bottles. The nylon also gives them a clear glass-like appearance which many parents prefer.

The nipples are made from medical grade silicone and this means that they are smooth and soft mimicking a mother’s breast. This is one of the reasons that babies can barely tell the difference between feeding from these bottles or actual breasts.

This natural texture of the nipple avoids nipple confusion, which for any parents that have faced this issue can be difficult to overcome.


At one point many containers for both liquid and food were lined with a chemical called bisphenol-A or BPA, this included baby bottles.

Concerns regarding its potentially harmful effects on humans arose and as a result, the FDA banned the use of BPA in food containers especially those used for babies such as bottles and sippy cups. 

The Mimijumi bottles do not contain any harmful chemicals, so they are considered safe for babies. They are BPA and BPS free, latex and lead-free, phthalates free and they also do not contain any known Estrogenic Activity agents or EA.

Non-free flow mechanism

Mimijumi bottles come with an innovative non-free flow mechanism.

This basically means that if you turn a Mimijumi bottle upside down not a single drop of liquid will come out. The liquid will only come out when your baby sucks on the nipple.

This same mechanism also helps your baby to control the flow of the milk as they do when they breastfeed because when they stop sucking, the milk stops flowing out, and if they such slowly the milk will flow slowly.

Non-slip Base

Most baby bottles do not come with a non-slip base but Mimijumi ones do. These bottles will remain upright and stable even if slightly knocked.

This is a great feature for when you are juggling a squirmy baby and trying to fill a bottle at the same time. You can be assured that they will remain upright.

Available Sizes

The Mimijumi baby bottles are available in two sizes – very hungry and not so hungry baby. The Very Hungry bottles can hold 8 ounces of milk, while the not so hungry bottles are smaller and only hold 4 ounces of milk.

You can buy bottles individually or you can purchase a starter set that contains two bottles.

Angled Neck

Unlike most baby bottles the neck of the Mimijumi bottle is angled or tilted. This allows for the nipple to remain at a right angle even when the baby is drinking from the bottle, this allows the baby to latch correctly just like at the breast.

This angled neck also allows your baby to remain in the proper upright position while feeding.

Anti-colic Vents

Colic is painful and uncomfortable for your baby. It occurs when your baby swallows too much air during feeding. This causes them to become gassy, colicky, and fussy.

Mimijumi bottles come with an anti-colic venting system. The vent allows air to enter and leave the bottle without mixing with the milk or formula while your baby is feeding. 

Pros of Mimijumi Bottles

  • They are both BPA and latex-free.
  • They can be opened and closed with one hand.
  • Anti-colic vents integrated into the nipple to reduce colic.
  • Non-free flow mechanism.

Cons of Mimijumi Bottles

  • Even when using the slow flow nipple some users have reported that the milk is still coming out too quickly for a newborn.
  • They are expensive, especially if you need to purchase several bottles.

Comotomo Bottle Review

Comotomo Natural Feel Baby Bottle, Green, 5 Ounce

Key Product Features


Comotomo bottles are made from medical-grade silicone. This silicone makes these bottles soft and squishy and gives them an almost skin-like texture.

It is also this silicone that gives them their cloudy appearance. Along with its natural breast shape, helps to prevent nipple confusion. This makes it much easier for nursing moms to switch between breastfeeding and bottle.

The challenge with these bottles is the medical-grade silicone that they are made of makes them incredibly difficult to warm as the silicone is heat resistant. 


Just like the Mimijumi bottles, Comotomo bottles do not contain any chemicals that could potentially pose a threat to your baby’s health.

They are BPA-free and do not contain phthalates or PVC.


The nipples are made from silicone too. So they are soft and flexible.

They are available in four different flow levels, which you will need to purchase separately depending on which one your baby needs. They are available in the following flow levels:

Flow Suitable Age
Slow 0-3 months
Medium 3-6 months
Fast 6+ months
Variable 6+ months

The Comotomo bottles also come with a leak-proof mechanism that only allows milk to flow when your baby is sucking. So even when these are turned upside down they will not leak.

Wide Neck

These bottles come with a wide neck opening allowing for easy cleaning without the need for a bottle brush. This wide neck also supports the natural breast shape.

Available Sizes

Comotomo bottles are available in two sizes 5 ounces and 8 ounces. They are also available in a bundle pack in either green or pink. 

The bundle pack contains two 5 ounce bottles and two 8 ounce bottles along with a set of slow flow, medium flow, and fast flow nipples.

Anti-colic Vents

Comotomo bottles have two anti-colic vents meaning that they are more efficient at expelling air from the bottles during feeding.

This also means that they are really good at preventing colic and excess gas in babies.

Pros of Comotomo Bottles

  • The bottles are soft and squishy just like the real thing.
  • A wide neck makes them easy to clean.
  • Easy and quick to put together.
  • Anti-colic vents help to reduce the amount of air your baby swallows.

Cons of Comotomo Bottles

  • The rings can be difficult to screw onto the base.
  • They are pricey.

Mimijumi vs Comotomo

Mimijumi and Comotomo bottles are both easy to use. But Mimijumi bottles can easily be opened and closed with one hand.

This is due to the nonslip base which allows the bottle to stay put on a counter or tabletop while you replace the nipple, add breastmilk or even prepare formula.

The only issue with the Mimijumi bottles is that the travel cap is very difficult to put on the bottle and does not stay in place, which can be a real pain when traveling.

Comotomo bottles are quite easy to use but they are difficult to open with one hand. They also do not have a nonslip base meaning that they can topple over easier if you are not using two hands.

Milk flow in both these bottles is controlled by your baby and they both come with different flow nipples depending on your baby’s age.

But some parents have found that the nipples in the Mimijumi bottles are too long and hard for a newborn to use.

Another issue that many parents have had is that even when using the slow flow nipples the milk comes out too fast for the baby to cope with.

Cleaning the Comotomo bottles is easy as they have a wide neck that isn’t angled like the Mimijumi bottle. This means that you can clean these bottles without the need for a bottle brush.

As the Comotomo bottles are also heat resistant they can be washed in hot soapy water and sterilized in a microwave by boiling.

Mimijumi bottles also have a wide enough neck in order that you can fit your hand in to clean them. They also have fewer parts than so are super quick to clean and set up.

Grip of both these bottles although different is still easy for your baby to handle. The Comotomo bottles are slightly textured to help your baby get a good grip, while the Mimijumi bottles are firmly making them easy for your baby to hold.

Mimijumi vs Comotomo – The Winner is…

Both of these bottles are highly rated by parents and experts alike and if you choose either of these products you will be equally pleased with your choice.

But for us, the Mimijumi bottles just pipped the Comotomo bottles at the post.

This is due to the fact that they are super easy to clean due to their wide neck, they have an excellent nonslip base, fewer parts and are angled to help your baby maintain the correct feeding angle.

The Final Thought

Whether you decide that Comotomo or Mimijumi bottle are the right choice for your baby you will not be disappointed.

Both of these bottles are a breath of fresh air in baby bottle design, which hasn’t changed much in decades.

Both offer parents a more natural breast-like shape and texture to help avoid nipple confusion and ensure that your baby’s feeding journey whether it be breast or formula is easy and pain-free.
