Bottle warmers are a convenient and easy way to warm breast milk or formula to a safe temperature. Some bottle warmers can also defrost frozen milk or warm up baby food. 

When choosing a bottle warmer, convenience is key. Look for options that are both easy to use and easy to clean. Ideally, the bottle warmer will fit a variety of bottle shapes and sizes so you can easily switch bottle types as your baby grows. For on-the-go families, consider a bottle warmer that can heat up bottles in the car. Families with multiples should look for an option that can warm two or more bottles at a time. 

When reviewing bottle warmers, we considered dependability, ease of use, ease of cleaning, and temperature control. We also looked for bottle warmers with additional features that some families might need, such as a built-in sterilizer, the ability to defrost frozen milk, and more. 

Based on our reviews, these are the best bottle warmers on the market today.

Pros

  • Remote start

  • Preset bottle warming time

New parents can use every convenience and extra minute of sleep they can get. This bottle warmer from The First Years provides a little bit of both. It allows you to chill a bottle in the machine before you hit the hay (it will stay cold for up to eight hours), then when you hear baby stir, just use the remote to start warming up the bottle, without even getting out of bed. Brilliant, right?

You can even preset the length of time you want the bottle to warm, so you can just push one button and catch a few extra Z’s until it’s ready.

What to Look for in a Bottle Warmer

Ease of Use

A bottle warmer should make feeding a hungry baby quick and easy. Try to find a bottle warmer that doesn't require any complicated assembly. You'll also want one that will heat the bottle fast and evenly. Additionally, consider the clean-up required. You'll want to keep the water reservoir clean between uses, so make sure it can be easily emptied and wiped down.

Features

Some bottle warmers offer chill, defrost, and keep-warm options, as well as a sterilization feature that not only works on bottles but other baby gadgets, too. There are also some that are remote-controlled so you can heat up the bottle without getting up from bed right away. How many and which features your bottle warmer should have will depend on your personal preferences.

Dependability

The most important quality you want in a bottle warmer is dependability. You need it to be able to warm bottles evenly and to the right temperature (as well as quickly). If breast milk or formula is not warmed evenly, or worse, it's too hot, you risk burning your baby's mouth and throat. Overheating milk also can lead to the breakdown of nutrients in the milk as well. And if the warmer fails to work at all, you're stuck looking for a plan B in the middle of the night.

Frequently Asked Questions

  • What are the benefits of bottle warmers?

    Bottle warmers heat up your baby's breast milk or formula. Some also can defrost frozen milk, heat up baby food, and/or accommodate two bottles at once. Many babies prefer to drinker warmer liquid, mimicking the warm temperature of breast milk babies get when breastfeeding. However, note that other babies may do just fine drinking room temperature or cold breast milk or formula from a bottle.

  • Can you use tap water in a bottle warmer?

    As long as your tap water is safe to drink, you can feel confident using it in your bottle warmer. In any case, the water does not go into the bottle, so your baby will not be consuming the water. See the manufacturer's instructions for the bottle warmer you buy. These may suggest distilled water to keep your warmer's water reservoir cleaner.

  • How do you clean a bottle warmer?

    Clean your bottle warmer with warm, soapy water. You can use a mild dish detergent. Be sure to rinse and dry thoroughly.

  • Can a bottle warmer stay on all night?

    A bottle warmer should not be used overnight, as it is not safe to use the formula or breast milk that was prepared from the day before and left out all night, even if it's kept warm. Breast milk and formula should be used within 4 hours or can be kept in the fridge for up to 4 days. Instead, the safest method is to use the bottle warmer to warm up the breast milk or formula right before you intend to use it.
