Do You Need a Bottle Warmer?
Whether or not you need a bottle warmer comes down to personal preference—both yours and your baby’s. Some parents choose to let frozen breastmilk thaw overnight in the fridge and serve it cold. Others choose to warm breastmilk or formula by placing the bottle in a bowl or a mug of hot water to slowly heat it up. (Microwaving breast milk or formula is a no-go, so skip that method.)
But some babies are pickier than others, and some parents don’t have the patience to wait around for milk to thaw or slowly warm in the sink. A bottle warmer is a small, generally affordable piece of baby gear that helps speed up the heating process and gets warm milk to your hungry baby’s mouth quickly and safely.

The biggest advantage of this MOSFiATA bottle warmer and sterilizer is that its large capacity allows you to heat up to four bottles at once, making it an especially perfect option for households with multiple babies.
Plus, it doubles as a sterilizer, and thanks to its larger size, that means you can also throw in a combination of baby gear, like pump parts and pacifiers. The machine is compatible with an array of materials (plastic, glass, and silicone) as well as wide-shaped containers, and its LED display screen is easy to read and understand. Choose temperature presets for warming milk, formula, or baby food, or set a timer to start the machine up in advance.
Thanks to the “defrost” setting, you can also heat up frozen milk pouches straight from the freezer. Keep in mind that the trade-off for a bigger capacity is that the wait time is a bit longer than other options on this list (a reported 6 to 8 minutes on the “rapid heating” mode). Your purchase also includes some helpful accessories, including a pair of tongs, two bottle brushes, and a removable tray to use when sterilizing small parts.
- Great value
- Heats quickly
- Compatible with all bottles
- Auto shutoff
- Must wait in between warming sessions
- Product inconsistencies
About Bottle Warmers
Even if you primarily breastfeed your baby, you will probably still run into occasions when you need to give your infant a bottle, either of your stored breast milk or formula. Many parents like to warm the milk before giving it to their baby, but this can be a tricky task.
Warming it in the microwave is generally not recommended, as the milk can get too hot there. Running it under warm water or putting the bottle in a bowl of warm water can be time consuming. Some parents, especially those who bottle feed regularly, thus like to invest in a baby bottle warmer.
Bottle warmers are small devices that quickly, safely, and consistently warm up your baby’s bottle to the perfect temperature. Putting it in a bottle warmer allows you to ensure that your little one will be safe from burns, and lets you warm up the bottle while you attend to your baby’s other needs.
The right bottle warmer should be a hands-free item, so you can put it in and let it do its work while you hold your baby. Warmed bottles should be near body temperature, about 98 degrees, so look for a bottle warmer that warms to that temperature. This helps to maintain the nutritional content of breast milk, which starts to deteriorate around 104 degrees. Ideally, you will also want a bottle warmer that can fit any type or size bottle, and one that is easily portable so you can take it on the go.
Features to Look for When Choosing a Bottle Warmer
When it comes to picking the best bottle warmer, Pampers Parents found the following features to be the most important:
- Temperature: Choosing a bottle warmer that helps you heat the milk to the temperature your baby prefers is a big help. You may want a bottle warmer that has a manual temperature setting rather than a pre-set feature, or a warmer that can heat milk that’s frozen.
- Ease of use: Parents wanted a bottle warmer that’s a cinch to use because convenience is such an important reason for getting a bottle warmer in the first place.
- Compatibility with bottles: It makes sense that some Pampers Parents noted preferring a bottle warmer that fits the size of the bottles and baby food jars they already have. If you don’t have bottles yet, try to buy the bottles that are compatible with the bottle warmer you choose.
- Price: As with all baby gear, value for money is important. More expensive doesn’t necessarily mean better, but you’ll want to ensure that the product you choose has the features you’re looking for while still fitting within your budget.
How We Tested
When I realized that most of the bottles my daughter would be drinking would be coming from the refrigerator, I knew I wanted a trusty bottle warmer on hand so she could have warm milk. I began to look into the best bottle warmers by getting recommendations from other moms and reading lots of reviews online.
I tested these bottle warmers by using them the same way I knew new moms would use them: I took cold bottles from the fridge and warmed them up to a temperature that wasn’t too hot or too cold. Ideally, you want your bottle to be between room temperature (72°F) and body temperature (98.6°F).
Breastmilk that is overheated can lose some of its nutritional benefits, and although you don’t have to worry about that with formula, you still don’t want your milk to be so hot that it burns your baby’s mouth.
For each bottle warmer, I tested 5 ounces of refrigerated water, read the instructions and followed the directions exactly, and filled the water reservoirs with room temperature tap water. All of the tests were done with popular Philips Avent Natural Baby Bottles.
