best baby bottle warmers

Using a baby bottle warmer is a quick and easy way to get your baby’s bottle at an ideal temperature. This is safer than using a microwave and more accurate than running the bottle under some hot water from the tap. As a mother, it has been my experience that the best bottle warmer depends on where you will use it and how often you need to warm up bottles.

Bottle warmer FAQs

I often see new parents ask the same questions about baby bottle warmers. I did my best to answer all these questions.

How fast do bottle warmers work?

This depends on the product you are using. Typically, you should be able to warm up a bottle or formula or breast milk between three to five minutes. Warming up a bottle of frozen milk can take up to 15 minutes.

Are baby bottle warmers safe?

Yes, but you need to look for a product designed for use with the material of the bottles you are using. Using a baby bottle warmer is safe than putting milk in a microwave since there won’t be any hotspots.

How to clean new baby bottles?

Baby bottles need to be sterilized before you can use them. Submerging the bottles, rings, and nipples in a pot of boiling water for five minutes should do the trick.

If you have a bottle warmer that doubles as a sterilizer, place the new bottles inside and select the sterilization setting.

Why warm bottles for babies?

If your baby is used to breastfeeding, she will probably prefer to drink lukewarm or warm milk from a bottle. Drinking warm milk can help your baby relax and go to sleep.

Warm milk might also be easier to digest. However, some babies like cold milk or cold formula so it’s not something you need to do.

How warm should a baby bottle be?

Breast milk starts losing its nutritional properties when heated above 104°F. If your baby is used to breastfeeding, heat her bottle to 98.5°F to mimic the natural temperature of breast milk. Heating your baby’s bottle in the 75 to 78° range is fine if your baby prefers lukewarm milk.

Can you sterilize baby bottles in the microwave?

You can use your microwave to sterilize baby bottles as long as your microwave is clean. You can either place the bottles inside of a microwave steam sterilizer or fill the bottles halfway with water and microwave them until you see steam.

How hot should the baby warmer be for sterilizing?

Using a baby warmer with a sterilization setting is more convenient than relying on your microwave. You will have to heat the bottles to 212°F with a water baby bottle warmer or to 250°F with a steam baby bottle warmer to properly sterilize them. Keep in mind that the bottles need to be exposed to hot steam or water for a few minutes.

How should I clean my baby bottle warmer?

The bottle warmer itself won’t be in contact with milk or formula, so it isn’t necessary to sterilize this appliance. However, you can wipe it with a damp cloth if you need to clean it.

You can also use hot soapy water to clean the inside of the appliance and use a mix with two parts cold water for one part white vinegar if you need to get rid of a calcium buildup inside of the bottle warmer.

How can I test the temperature of the bottle?

You can use a food thermometer to test the temperature of the milk. You can also sprinkle a few drops of milk or formula on the inside of your wrist. This is an area where your skin is very sensitive, and you should easily be able to tell if the milk is too hot for your baby.

Types of baby bottle warmers

I put together this list of different types of baby bottle warmers to help you decide which appliance would be best for your needs and lifestyle.

Electric bottle warmer

These are typically small appliances that you can plug in your kitchen and fill up with water. Electric appliances either heat up the water or turn it into steam.

An electric appliance would be the best baby bottle warmer for you if you plan on using it at home and need something quick and efficient.

Portable travel bottle warmer

Battery-powered portable bottle warmers have a heating band that wraps around the bottle. You can use these products to sterilize a baby bottle, but this is a convenient gadget to have when you are on the go.

Bottle warmer bag

Bottle warmer bags keep milk or formula warm thanks to insulating materials. You will need to heat up the bottle in advance and place it inside of the insulated bag to keep it warm.

Car bottle warmer

These bottle warmers are somewhat similar to portable travel bottle warmers since they use a heating element or heating band rather than water or steam. However, you can power these bottle warmers with a car adapter rather than a battery.

Double bottle warmer

These bottle warmers are typically electric appliances designed to be used at home. However, they are large enough to accommodate two bottles, which helps you save time when sterilizing baby bottles.

Bottle and food warmer

Some of the best baby bottle warmers can fit baby food jars. This convenient feature allows you to warm up food without having to worry about hotspots.

Steam bottle warmer

These appliances use steam to warm up baby bottles. This is typically faster than using water, but some steam bottle warmers require you to use a precise quantity of water to reach the desired temperature.

How to use a baby bottle warmer

If you have a water or steam bottle warmer, you will need to fill the appliance with water. You can then select the desired temperature and insert the baby bottle in the bottle warmer.

Some baby bottle warmers have a timer while others will require you to carefully monitor the time, so you can turn them off before the milk gets too warm.

Options of the best baby bottle warmers

I have used a few different bottle warmers over the years. These are the options and features that I think are most important to look for:

  • Think about how much counter space you have in your kitchen.
  • Will you use the baby bottle warmer at home or on the go?

  • Make sure you can use the baby bottle warmer with the bottles you already own.
  • Do you want to use the appliance to warm up milk and food, or will you need a sterilization setting as well?
  • Will you need different temperature settings?
  • A baby bottle warmer with a timer and an auto-shutoff feature is a plus.
  • A steam baby bottle warmer is typically faster, but there are fewer risks of accidental burns with a water baby bottle warmer.

How the best bottle warmer was selected

As a mother, I know that the best baby bottle warmer is an appliance you should be able to use while holding a crying baby. The ideal baby bottle warmer should reach the desired temperature within a couple of minutes and shouldn’t require you to measure water or go through a complex settings menu.

Reading reviews written by other parents made me realize a lot of people will be using their bottle warmer at night to warm up breast milk. They need an appliance where you can simply push a button and not even think about which temperature you need to select.

This is why I think the Baby Bottle Warmer & Bottle Sterilizer, 3-in-1 Steam Sterilizer Bottle Warmer Portable Warming Breastmilk and Baby Food with accurate Temperature Control is the best baby bottle warmer money can buy.

I liked the compact design, the fact that you can sterilize two bottles and once, and the five temperature settings. I think the knob temperature control is easy to use, and you can see the difference between the sterilization temperature and the range of temperatures suitable for food or milk.

The Runner-Ups

Kiinde Kozii Bottle Warmer and Breast Milk Warmer

Kiinde Kozii utilizes convection technology to warm milk and baby bottles. Here’s how it works: first, the water reservoir of the warmer is filled with water. Then, as the water heats up, it rises and circulates inside the warmer to heat the milk bottle. In the case that the water level becomes too high, the excess warm water enters the overflow valve and back into the water reservoir.

This process allows the even heating of your baby’s milk and prevents hot spots. The Kozii bottle warmer also includes an auto shut-off feature and a defrost setting. The latter is especially helpful if you need to thaw frozen breast or formula milk. Kiinde Kozii takes pride in their “one size fits all solution” which means that this warmer can accommodate baby bottles in various sizes including baby food jars.

Philips AVENT Bottle Warmer

The Philips AVENT Bottle Warmer uses the same heating concept as the Kozii bottle warmer. However, this one is a cheaper alternative. The main feature of the product is its large opening which can hold bottles of various sizes. So, if you have Comotomo bottles at home which are known for their wide mound, they will fit just right in this warmer.

Some of the complaints about this product include the lack of a timer and an auto shut-off feature. Also, it has a slower heating time compared to other products. While the company recommends a 3-minute heating process, the actual procedure takes longer.

Baby Brezza Safe & Smart

For the moms who appreciate hi-tech products, the Baby Brezza warmer is the perfect choice for you. The product features three modes: steady warm, quick warm, and defrost. The steady warm mode uses the water bath method while the quick warm uses steam. The warmer even comes with a downloadable App that allows you to control it remotely. It’s also safe to use for both plastic and glass bottles of various sizes.

As you might have expected, this product is quite pricey and not to mention, relatively bulkier than other warmers. However, if you don't mind spending more on a bottle warmer and you have a lot of space to spare for this product, then you should consider purchasing one.

Tips for buying the best bottle warmer

Here are a few tips to keep in mind when you compare different baby bottle warmers:

Bottle Warmer buying tips

  • How much money are you willing to spend on this appliance?
  • Do you need a bottle warmer that doubles as a bottle sterilizer?
  • Will you use the appliance at home, and will you ever need to transport it?
  • Steam bottle warmers are usually faster, but a water bottle warmer might be more affordable.
  • Do you need different temperature settings or a simpler bottle warmer where you simply need to push a button and wait?

Other baby products to buy

There are additional baby products that will come in handy. In my experience, these are the products parents can benefit from:

  • Stock up on baby bottles, rings, and nipples.
  • Get a drainer mat and drying rack for the baby bottles
  • If you choose a bottle warmer that doesn’t double up as a sterilizer, think about purchasing a sterilizer, a container for sterilizing bottles in the microwave, or a sterilizer bag so you can safely store your baby products.
  • Get some baby bottle brushes to make cleaning easier.
  • Find a sturdy insulated bottle bag when you're on the go.

The best baby bottle warmer depends on where you will use it, and on whether or not you will need different temperature settings to choose from.

I think the Baby Bottle Warmer & Bottle Sterilizer, 3-in-1 Steam Sterilizer Bottle Warmer Portable Warming Breastmilk, and Baby Food with accurate Temperature Control would be an excellent investment for most parents but take the time to shop around and compare different appliances know that you know more about bottle warmers.
