Naturally, breast milk is body temperature so having warm milk is more preferred by babies and is more soothing. If you are storing your breastmilk and need to reheat it to feed to your baby you may want to consider one of the best bottle warmers below.
Compared to microwaves, they don’t create hot spots on the milk that can burn baby’s mouth so they are much safer.
Here’s what you need to know to pick out the best bottle warmer for you:
Do you need a bottle warmer?
When you are expressing milk and storing them in the fridge or freezer, you need to thaw it first before giving it to the baby. You could give it to the baby cold but if your baby fusses and won’t drink it, you may need to warm the milk up first.
You can use a bowl of hot water to warm up the milk slowly but you also wouldn’t have control over the temperature and overall the process would take longer compared to having a baby bottle warmer.

Advantages of bottle warmers:
Bottle warmers will be able to control the temperature of the milk when heating so that it doesn’t get too hot and you won’t end up losing all the nutrients found in the milk.
Speed in heating
It could differ depending on how cold your milk is but the average time it takes to warm your bottle is around 3 minutes.
All you have to do is turn on the machine and wait for it to do its work. There are also some bottle warmers that will indicate that it is warm enough and ready for baby. While waiting, you can multitask and do other things you need to do.
Kinds of bottle warmers
- A home bottle warmer system that uses steam to warm up your bottle of milk.
- A bottle warmer that heats a water bath that your bottle will be sitting in to warm it up.
- A portable baby bottle warmer that you can bring around while traveling. This system would either use a thermos that you can fill with hot water or the bottle warmer itself can be plugged to your vehicle to make the device work.
How bottle warmers work
A baby bottle warmer that uses a water bath will slowly heat up the bottle using consistent heat. Bottle warmers that use steam to heat up the bottle will work more quickly than the water bath system although the temperatures could get higher so you have to be more careful. You may also need to wait a little bit for the outside of the bottle to cool down before giving it to your baby.
Factors to consider when choosing the best bottle warmer:
There are bottle warmers that have a set temperature that will heat your bottle to while others will have adjustable dials. The important thing to remember is that milk shouldn’t be heated to over body temperature (40 degrees Celsius) since this will mean the nutrients will already be lost. The milk should be warm but with no hot spots.
Ease of use
Bottle warmers should not be complicated to use. Make sure the one you choose will have dials that are easy to use and also a feature that will tell you when the bottle is ready.
Easy to clean
By taking care of your bottle warmer and cleaning it properly, it will last you longer and perform better. Take note that bottle warmers that use steam reservoirs will have the tendency to develop mold so it’s very important to always do a checkup and clean them if you end up going for this kind.
Look for baby bottle warmers that warm up to body temperature or those that use controlled steam. Some devices might claim to heat up really fast but it could be more dangerous and will pose more risks for scalding.
There are some bottle warmers that will fit tall and narrow bottles so if you have a wider bottle, you might have problems fitting it in. It is best to go for a bottle warmer that can be flexible and fit different dimensions and shapes of baby bottles.
Some bottle warmers can be used to warm up baby food, which means you’ll get the most out of your investment as your baby gets older. There are also some devices that have extra functions like sterilizers or food processors.
If you are going away for the weekend, it is best to have a portable bottle warmer to bring with you. You can also find one that is compact that will fit your suitcase or bag.
