Mimijumi Bottle Review 

key product features

1. Material

Mimijumi bottle is made from high-quality Swiss nylon. Thus, it is much firmer than pure silicone bottles. Despite being firm, the nylon makes the bottles strong in that they do not break easily; hence they are as durable as the plastic bottles.

The nylon also gives the bottle a clear glass-like appearance so you might actually think they are made of glass.

The nipple is made from medical grade silicone. This gives it a texture that is soft and smooth like the natural mother’s breasts. Hence, babies can hardly differentiate between feeding from these bottles and natural breasts.

The natural feeling prevents nipple confusion, which is a major problem which parents face when they introduce their babies to bottles.

2. No harmful chemicals 

A while ago, most liquid and food containers including baby bottles were lined with a chemical known as bisphenol A (BPA).

Concerns arose regarding its potentially harmful effects on humans, especially in babies. As a result, the FDA banned the use of BPA in food containers particularly in containers like bottles and sippy cups.

However, some manufacturers still attempt to use BPA in plastic containers. That is why it is important that you make sure any product you buy for your baby is BPA free.

This bottle does not contain any harmful chemicals, so it is very safe for babies. It is BPA free, BPS free, latex and lead-free, phthalates free and does not contain any known Estrogenic Activity (EA) agents.

3. Leak-proof nipple (Non-free flow mechanism)

If you take a Mimijumi bottle with any liquid and hold it upside down, not even a drop will leak.

This is attributed to its innovative non-free flow mechanism at the nipple, which prevents any liquid from flowing out. Milk comes out only when a baby sucks on the nipple.

This mechanism also helps the baby to control the flow of milk because when he or she stops sucking, the milk stops flowing out and if he sucks slowly, the milk flows slowly.

Thus, this is a good innovative design, which also makes Mimijumi suitable bottle for traveling.

4. Non-skid base

Few very brands of baby bottles have a non-skid base and Mimijumi is one of them. Most bottles will topple over even with the slightest knock but these bottles remain stable on the table or countertop.

This means that you will be able to fill the bottle without sliding all over the kitchen counter while you hold a wiggly baby on the other arm.

5. Two Sizes

This brand of baby bottles comes in two different sizes; Very Hungry and Not So Hungry bottles.

The Very Hungry bottles are larger; 8 ounces and can hold up to 240 ml of milk.

The Not So Hungry bottles are smaller; 4 ounces and hold about 120ml of milk.

You can choose to buy each bottle separately or get a Mimijumi starter set, which has the two bottles.

6. Angled neck

Unlike the Comotomo, the neck of the Mimijumi bottles is slightly angled/tilted. The neck is angled so that even when the bottle is inverted during feeding, the nipple still remains horizontal and at a right angle allowed the baby to latch properly just like in breastfeeding.

It helps the baby to grasp during feeding, which provides a natural experience of breastfeeding.

In addition, the titled neck allows the proper upright position of the baby during feeding.

7. Anti-colic vents

When a baby swallows too much air during feeding, they become gassy, colicky and fussy.

This is why the Mimijumi bottle has anti-colic venting system. The vent allows that air to enter and leave the bottle seamlessly without mixing with the milk or formula while the baby is feeding.

In addition, the non-free flow mechanism that helps babies to control the flow of milk also helps to minimize the amount of air swallowed during feeding.

8. Measurement markings

The bottles have measurement markings that show the amount of liquid. They also come with a jar to help you in measuring accurate feedings.


Comotomo Bottle Review

Key Product Features

1. Material 

Comotomo bottles are made from medical grade silicone. Medical grade silicone is approved by the FDA as a safe material for making food and drinks containers like baby bottles, plates and sippy cups.

Silicone makes these bottles soft, squeezable and gives them a skin-like texture. This coupled with the natural breast shape of the bottle helps to prevent nipple confusion. Thus, it is easier for nursing moms to switch from breastfeeding to bottle and vice versa.

The only challenge with medical-grade silicone is that it makes Comotomo bottles difficult to warm since silicone is heat resistant. If you are having a difficult time warming these bottles, this bottle warmer works great.

2. No harmful chemicals

Just like the Mimijumi bottles, Comotomo bottles do not contain any chemical that can pose a risk to your baby’s health.

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

3. Nipples

As aforementioned, the nipples are made of silicone. So they are soft, flexible and 100% safe.

They are available in different flow levels, which you buy separately depending on your baby’s age. There is a slow flow nipple that has 1 hole that is suitable for a newborn aged 0-3 months. The medium flow nipple has 2 holes and it is appropriate for babies aged 3-6 months.

The third type of nipple has 3 holes for the fast flow of milk, which is suitable for babies aged 6 months and above. There is a fourth nipple type known as variable flow, which is Y shaped. This is designed for babies 6 months and older who are starting to take thicker fluids.

4. Leak-proof nipple

Just like the Mimijumi, when you hold the Comotomo bottle with milk upside down it will not leak. This is because it has a leak-proof mechanism that allows milk to flow only when the baby is sucking.

5. Wide neck

The neck of these bottles is wide to allow easy cleaning without the need for a bottle brush.

The wide neck also supports the wide mound, which is shaped like a natural breast. So, are able to latch naturally like they do when breastfeeding.

6. Anti-colic vents

Comotomo bottles have 2 anti-colic vents unlike Mimijumi, which has only one. This means that they are more efficient at expelling air from the baby during feeding.

Thus, when compared to the Mimijumi bottle, Comotomo bottles are the best for preventing colic and gas in babies.

7. Two Sizes

These bottles come in two sizes as well; 5 ounces and 8 ounces. The 5 ounce bottles come with a slow flow nipple while the 8 ounce bottle comes with a medium flow. You can, however, purchase replacement nipples depending on the needs of your baby. For instance, you can get the variable flow nipple if your baby starts taking thicker fluids.

8. Measurement/volume markings

There are volume markings on the side of the bottle that have a different texture from the rest of the bottle. The markings are in fluid ounces (oz.) and in milliliters (ml).

Mimijumi vs Comotomo bottles overall performance

Ease of use

Mimijumi bottles are very easy to use. When you are holding a hungry-crying baby, you can easily open and close this bottle with hand. The non-skid base allows the bottle to stand firm on a tabletop as you replace the nipple, add the milk or prepare the formula without the bottle toppling over.

However, the travel cap on this bottle is difficult to put on. It does not stay in place, which becomes an inconvenience when traveling.

Comotomo bottles are relatively easy to use. However, they are a bit difficult to open with one hand. They also do not have a non-skid base so they can topple over easily if you are not using both hands.

Cleaning

Since the Comotomo bottles have a wide-neck and not angled like the Mimijumi bottles, they are easy to clean. You do not even need to use a bottle brush since your hand can easily fit into them.

Moreover, Comotomo bottles are heat resistant. So, they can be washed in hot soapy water or a dishwasher and sterilized in a microwave, by boiling or using a sterilizer.

Similarly, Mimijumi bottles also do not need a bottle brush in order to reach all the corners of the bottle when cleaning. This is because despite being angled, they are wide enough to fit your arm when washing. Moreover, they have fewer parts; hence, you will not take too much time cleaning or setting up.

Milk flow

Milk flow in both Comotomo and Mimijumi bottles is controlled by the baby. Both have different milk flow nipples, which you can get based on your baby’s needs.

However, for Mimijumi bottle, some parents have found the nipple to be too long and hard for a newborn baby to use.

In addition, even with the slow flow nipple, some parents have argued that the milk let down is too fast especially for a newborn.

Baby grip

The Comotomo bottle is lightly textured to enable the baby to hold it without slipping. So it is very easy to grip. Similarly, the Mimijumi bottle is firm and makes it easy for the baby to grip.

My take

From this review, it is clear that both bottles are very similar. For instance, they both have a silicone nipple and a mound that is shaped like a breast. Thus, they mimic the natural breast, which helps to prevent nipple confusion. This means that they are also the best bottles for breastfed babies who refuse the bottle.

The two bottles are also easy to clean, have a leak-proof mechanism, antic-colic vents and different bottle and nipple sizes.

However, both bottles fit in selected bottle warmers due to their wide neck.

These bottles only have minor differences. For instance, the Comotomo bottle is soft and squeezable while the Mimijumi bottle is firm and unsqueezable. If your baby loves to squeeze the breasts a bit when feeding, he or she might not be able to do this if feeding on the Mimijumi bottle. So he might notice the difference between your breasts and the bottle.
