Best Bottle Warmers: Fast, Budget, Twin and Travel Picks

A bottle warmer does one job: gets milk to body temperature evenly while a hungry baby waits. The five below run from a $16 basic warmer to an $80 cordless one for the diaper bag, with a twin warmer and two fast, feature-packed models in between.
Before you buy, know that you may not need one. The Centers for Disease Control and Prevention (CDC) says breast milk doesn't need to be warmed and can be served cold or at room temperature. If you do warm it, never use the microwave.

The Grownsy 8-in-1 gives you more control than the Philips for about $19 less, $30.98 from Amazon. It has settings for fast warming, thawing, keeping milk warm, steaming, warming food, a timer and adjustable temperature, all on a digital display.

It has a 4.4 rating from about 14,500 reviews.

| Controls | One button, water vial measure |
|---|---|
| Fits | Most wide, narrow and angled bottles |
| Extra | Pacifier sanitizer |
| Cleaning | Top-rack dishwasher safe parts |
| Sold by | Amazon |
The First Years Simple Serve is the cheapest pick at $16.39 from Amazon and the most reviewed, about 22,300 with a 4.4 rating. It doubles as a pacifier sanitizer.
It works by measured water: you fill the vial to the line for your bottle, pour it in, press the button and the light goes off when it's done, then it shuts off. The listing says it fits most wide, narrow and angled bottles, and the vial, basket, ring and lid go on the top rack of the dishwasher.
There's no temperature control or keep-warm mode, so check the milk on your wrist each time.
Good for
- About $16
- Parts go in the dishwasher
Watch Out for
- No temperature setting or keep-warm
- You measure the water each time

The listing gives 3 to 7 minutes to warm cold milk to body temperature, with a timer and auto shut-off. It was $44.99 from Amazon, with a 4.5 rating from about 8,000 reviews.

How to Warm Breast Milk Safely
The CDC's guidance for breast milk is short. Warming is optional: milk can be served cold or at room temperature. If you warm it, keep the container sealed and set it in a bowl of warm water or hold it under warm, not hot, running water for a few minutes. A bottle warmer does the same job with a water bath or steam.
Never use the microwave. The CDC says microwaving can destroy nutrients in breast milk and create hot spots that can burn a baby's mouth. Test a few drops on your wrist before every feed.
Timing Rules from the CDC
- Use milk that has been warmed or brought to room temperature within 2 hours.
- Finish leftover milk from a feeding within 2 hours, then throw it away.
- Use milk thawed in the fridge within 24 hours of fully thawing, and never refreeze it.
How to Choose a Bottle Warmer
Simple or Programmable
One-button warmers like the Philips Avent and The First Years are hard to get wrong at 3 a.m. Digital warmers like the Grownsy models add thaw, keep-warm and timer settings, which help if you warm frozen milk or prepare bottles before bed.
Bottle Fit
Wide, narrow and angled bottles don't all fit every warmer. The Philips takes bottles up to 11 ounces, and The First Years lists wide, narrow and angled bottles; check your bottle against the listing before you buy.
One Bottle or Two
For twins, a double warmer like the Grownsy Double saves a second wait. For one baby, a single warmer is smaller and cheaper.
Home or Travel
Plug-in warmers stay on the counter. A cordless warmer like the Momcozy works in the car or at the park, but it costs more and needs charging.
Bottle Warmer Questions
Do I Need a Bottle Warmer?
Not necessarily. The CDC says breast milk can be served cold or at room temperature, and a bowl of warm water works if you want it warm. A warmer is faster and more even, which helps at night.
Can I Warm Breast Milk in the Microwave?
No. The CDC says microwaving can destroy nutrients and create hot spots that can burn your baby's mouth.
How Long Is Warmed Breast Milk Good for?
Use it within 2 hours, according to the CDC, and throw away what's left after a feeding.
The Bottom Line
For most parents the Philips Avent Premium is the one to buy: one button, even warming and room for most bottles. The Grownsy 8-in-1 adds thaw and timer settings for about $31, and The First Years Simple Serve does the basic job for about $16. Get the Grownsy Double for twins, and the Momcozy Portable if you need warm milk away from home.
