Are Baby Bottle Warmers Necessary?

I know what it’s like to look at a baby gadget you spent a lot of money on sitting in the corner gathering dust. Especially when you’re a new mom, you tend to err on the side of just getting that extra bit of baby gear rather than feeling like you’re shortchanging your child in any way.

But by the time baby number two comes around, you might be seriously wondering where the line is between “helpful lifesaver” and “useless waste of money.”

To help you decide whether a bottle warmer is really worth getting, consider the following:

  • The number of children: Twins or more will likely need one, whereas single babies could do without.
  • The question of consistency: If you’re the only one who’ll be doing it, heating bottles under warm tap water might be fine. But if your baby is frequently cared for by others, it’s a nice way to keep things consistent.
  • Frequency of use: There’s no point investing in a bottle warmer if you seldom need to heat any bottles. If your child is still breastfeeding or enjoys cold bottles just as well, you can skip the warmer. Likewise, if you’re using formula or not pumping breast milk at all.
  • Cost: Of course, the cost is always a consideration. For the price, you might simply prefer heating bottles some other way and calling it a day. Another option is getting a second hand warmer if you’re not sure how much use you’ll get from it.

If bottle feeding looks like it’ll be a big part of your future, a warmer might save you countless hours of hassle and take one more thing off your plate. For some moms, the sheer convenience makes them a no-brainer. For others, they can whip together a perfectly warmed bottle in around the same amount of time it takes the bottle warmer to do it.

Make sure if you’re warming breast milk the warmer is made for breast milk and isn’t going to overheat and deteriorate the beneficial molecules.

Types of Bottle Warmers

Steam vs. Hot Water

Product Image of the Kiinde Kozii Baby Bottle Warmer and Breast Milk Warmer with Safe Warm Water Bath...

The basic difference between most warmers is whether they use steam or a bath of hot water to warm milk.

Steam is faster but can scald you or your baby if you’re not careful.

Water baths heat more gently and evenly, but they take a lot longer than steam to do it.

Electric vs. Non-Electric

Product Image of the Dr. Brown's Deluxe Baby Bottle Warmer

Most warmers are plug-in appliance styles that go on your kitchen counter to help you with your normal bottle prep. These can use either steam or hot water, and are great if you’re doing most of your feeds at home.

Non-electric styles rely instead on insulation, or battery power to keep milk warm, so can be used on the go. For insulated bags, you’ll need to heat the milk up first, though.

Car or Travel Bottle Warmers

Many non-electric styles are designed specifically for use in the car. Some are well-insulated, some use battery power and some plug directly into the car’s DC connector via an adaptor.

Naturally, these are smaller and contain no water to spill.

Combined Bottle and Food Warmers

Some electric countertop warmers are designed to heat up baby food jars as well as milk bottles.

They often come with a removable tray or basket but may need a little extra care to keep them clean. Some warmers also have room to heat two bottles simultaneously, making them great for twins.

How to Choose the Best Bottle Warmer

If you’ve decided to take the plunge and buy one of the best baby bottle bottle warmers, here are some things to consider:


You’ll want to find one that can also be used to heat baby food. That way you’ll get more bang for your buck when your baby is old enough to start eating.


The best bottle warmers should be able to warm a bottle quickly. Babies aren’t known for their patience, and no mom wants to wait a full 10 minutes while trying to console a screaming baby.

Uniform heating

The final product should be evenly warmed milk with no hot or cold spots.


A bottle warmer should be versatile enough to handle bottles in many sizes and shapes.


You want a model that you can take on weekend getaways. I know packing for a vacation when you have a baby is no easy feat – you don’t want your warmer to take up half the space you have.

Small size

Make sure the bottle warmer is compact enough to fit in a small suitcase. There are even car warmers to warm breast milk while you’re on the go.

Safe for breast milk

Maintains the integrity of the nutrients by not overheating or scalding the breastmilk.

Five ounces are heated in around three minutes. The water in the unit circulates continuously to make sure the milk is mixed and heated throughout.

Ways to Warm Baby Bottles

I understand the need to cut corners when you have a new baby. The amount of baby gear needed to take care of one tiny human being is staggering. The baby gear takes up a lot of storage space in your house, and the money you’ve spent in preparation for motherhood makes you feel sick.

It takes a small fortune to raise a child (1). It’s hard to spend money on something like a bottle warmer when you feel there are other ways you can heat up your baby’s milk. And you’re right; alternatives do exist.

Let’s look at some other ways that you can warm your baby’s bottle:

  • Using the microwave: If you learn one thing from this article, it should be never to use a microwave to heat up your baby’s bottle. This might be the single worst way to warm a bottle. The microwave doesn’t heat a bottle evenly – it leaves areas where the milk is too hot, which can burn your baby.
  • By running warm or hot tap water over the bottle: This might work, but it takes a couple of minutes to heat the bottle to the desired temperature. If you leave it under the hot water too long, it can become too hot for your baby. If you don’t warm it long enough, your baby might not want it, especially if she’s picky about the temperature of her milk.

Another drawback to running hot water over the bottle is that you need both hands to do this, and while you’re busy that means no one is comforting your crying baby. With a bottle warmer, the machine does the warming while you do the cuddling. I know which job I would rather do – cuddling a baby wins every time.

Are Bottle Warmers OK for Breast Milk?

Bottle warmers provide an excellent way to warm up breast milk that has been thawed or refrigerated. Some warmers can even heat up breast milk straight from the freezer. Some babies don’t mind drinking cold bottles, while others prefer warm ones.

It depends on the baby, I’ve had one baby who would take a cold bottle of breast milk with ice chunks from it being frozen and second baby who needed warm breast milk.

Whether you use a bottle warmer or another method, bottles shouldn’t be heated much higher than body temperature. If you have heated up your breast milk and your baby refuses to take her bottle, it is generally safe to only heat it one more time (2).

Keep your fingers crossed that your baby will take her bottle after you’ve reheated it. As awful as it is to waste breast milk, if she doesn’t take it that second time you should toss it down the sink. It’s better to be safe than sorry when it comes to your baby’s health.

How Do I Use a Bottle Warmer?

Every model will come with its set of instructions – you should read these carefully. Not all bottle warmers operate in the same way. Let’s look at the operating instructions for the most popular warmers on the market.

How to Use a Tommee Tippee Bottle Warmer

  1. You place your baby’s filled bottle in the warmer.
  2. You put water in the warmer compartment until it reaches 10 millimeters below the rim. If your bottle is bigger, you’ll want to allow more space by filling the warmer compartment to about 12 millimeters underneath the warmer’s rim.
  3. Check to see that the warmer is on the “MIN” setting before you plug it in.
  4. Plug it in and make sure the indicator light comes on to show the unit is working.
  5. Move the dial to setting 3.
  6. When the water is heated adequately, you’ll see the light go off. That doesn’t mean the milk is ready, though. It just means the water has reached the right temperature to heat the milk.
  7. Give the milk time to heat. Follow the heating guidelines in the instructions that come with the warmer. For example, if you’re using a 5-ounce bottle from the refrigerator, you’ll want to warm it for 5 minutes, but if the bottle was at room temperature, you’ll only want to warm it for 4 minutes.
  8. Be careful when taking the bottle out of the warmer because the water surrounding it will be hot.
  9. Always check the temperature of the milk on the inside of your wrist to make sure it isn’t too hot for your baby.
  10. After you are finished with the warmer, put the dial back on the lowest setting and unplug it.

If you are warming baby food with the Tommee Tippee Closer to Nature bottle warmer, there are different instructions (3).

How to Clean a Bottle Warmer

Before cleaning a bottle warmer, you should always make sure it’s unplugged first to avoid injury. You should discard any water in the unit that was used to heat any previous bottles and follow the specific instructions each unit comes with because they won’t all have the same directions.

These are the basic guidelines you can follow:

  1. Pour some boiling, soapy water into the reservoir.
  2. Allow the water to loosen any debris by sitting for several minutes.
  3. Pour out the water into your sink.
  4. Take 1 spoonful of room temperature water and 2 spoonfuls of uncooked non-instant dry rice into the reservoir and shake it.
  5. Rinse the bottle warmer well to remove any excess rice grains.

The Bottom Line

The primary purpose of the best bottle warmer is to heat up a bottle quickly and safely so you can feed your crying baby as soon as possible. Babies cry constantly, and if you can cut back on the time they spend doing that, you’ll be a much happier and well-rested mom!

You shouldn’t have to part with much of your hard-earned money for a warmer, and you shouldn’t need a Ph.D. to figure out how it works. You want something simple to operate that won’t drain your savings account.

Now over to the moms out there – do you use a bottle warmer, and if so, which one has earned your trust and which one should be tossed? We’d love to know in the comments!
