Many parents are still using the slow, old ways of warming bottles – standing by the sink and running the bottle under warm water, or letting it sit in a bowl of hot water to warm up. This can take many long, agonizing minutes while you’re left holding a screaming baby at 3 AM, only to check the bottle 5 minutes later to discover it’s still cold. 

Both of these methods waste time and fail to consider the needs of the parent and baby. This is where bottle warmers come in.

Having a good, reliable bottle warmer will ensure that your baby gets its milk as quickly as possible. Ensuring that the bottle warmer performs consistently and produces a bottle at the same safe temperature every time is also key.

With a bottle warmer, you can prep the formula easily, even in the middle of the night, right in the baby’s nursery. You don’t need to go to a sink, get any bowls, run water, or anything.

This is why having a reliable and easy-to-use bottle warmer for baby formula or frozen milk is a must for any new parent. In this article, we’ll be reviewing the best bottle warmers we’ve found on the market.

Why do I need a Bottle Warmer?

When feeding a baby from the bottle, breast milk should be reheated to be near body temperature, 98.6°F. While formula technically does not need to be warm to be served, the reality is that most babies are much happier and feed more readily when the bottles are heated up.

Babies can digest warm milk more easily than when it is given cold, and which can reduce stomach aches and fussiness.

If those weren’t reason enough – a newborn will on average wake up 2-3 times per night, wanting to feed. If you spent 10 extra minutes setting up and waiting for the bottle to be warmed in the sink or a bowl, then that’s 30 minutes of lost sleep per night. That 30 minutes per night scales up to 3.5 hours per week, or 15 hours of sleep lost per month!

Clearly, getting the milk to temperature in the shortest time possible is highly important for your well-being as a parent. Remember that, it’s not only lost sleep for you – this is also lost sleep for the baby.

With that said, let’s take a look at the best bottle warmer.

Features to look for when choosing the Best Bottle Warmer for Formula or Breast Milk

When you are choosing the best bottle warmer for your needs, here are some of the key features you should keep in mind:

Consistent and Safe Heating

you should ensure that the warmer will heat the milk or food evenly, without hot spots, and without killing off the healthy nutrients from the breast milk.


Ability to fit bottles, jars, and cups of all types and sizes, or at least those that you use at home.

Also, some bottle warmers can be used for warming up baby food and for sterilizing pacifiers and bottle nipples in addition to warming milk. Consider if these features will be important to you for how you plan to use it.


The ability to defrost breast milk (if you are freezing your milk) can be a big plus. Some warmers only have one setting, designed to warm cool liquid, instead of defrosting frozen breast milk.

A dedicated setting will help save time in those early morning hours when you can’t afford to be doing mental math on how to set up the bottle warmer while a baby is screaming in your ear.

Auto Shut-Off

This feature is useful if you want to prevent overheating – many types of warmers will not at all prevent you from boiling the milk – destroying important nutrients and forcing you to either wait for it to cool down or mix it with cold milk to attempt to fix the temperature.

Size and Portability

You should choose a bottle warmer that can fit on your nightstand or other designated space. Consider where and how you will be using the warmer – will you take it with you in the car, or will it only ever live on a nightstand?

Ease of Use

Remember that in most cases, you will be using the warmer while the baby is crying for food, so you will be under pressure to do it as quickly and easily as possible. Keeping it simple will lower your stress!

Ease of Cleaning

As with all accessories which come into contact with your baby’s food, you should pick a warmer which is easy to keep clean, safe, and sanitary
