Are Baby Bottle Warmers Necessary?

As new moms, we can spend a lot of money on baby gadgets that end up sitting in the corner gathering dust. After all, it seems better 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: If you have one baby, it might not be necessary, but with twins or more, you’re likely to need one.
  • 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, 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.

If you’re wraming breast milk, make sure the warmer is made for this 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

Most warmers are plug-in appliances 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 a Baby Bottle Warmer

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

Multipurpose

You may 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.

Quick

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. Ideally, the warmer should complete the warming cycle in between two and five minutes.

Uniform Heating

The final product should be evenly warmed milk with no hot or cold spots. The best way to check this is to see what other customers are saying.

Adaptable

A bottle warmer should be versatile enough to handle bottles in many sizes and shapes. You may also want to consider one that works for a variety of bottle materials such as plastic, stainless steel and glass.

Portable

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. If you travel a lot, consider a battery-powered option, a car bottle warmer, or a countertop option that doesn’t take up that much space.

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. Some span to 8 x 10 inches, while others are 5 x 6 inches.

Safe for Breast Milk

If you’re warming breast milk, make sure to choose one that maintains the integrity of the nutrients by not overheating or scalding the breastmilk.

Different Ways to Warm Baby Bottles

It takes a small fortune to raise a child. 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 people warm baby bottles and what we think of them:

  • 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, leaving your upset baby without comfort. 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 Safe 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 a 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.

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.
