  • Speed

It is better to buy a bottle warmer that warms the bottles in the shortest possible time, thus you will save time and you can feed the baby as soon as it starts to cry.

  • Capacity

The vast majority of bottle warmers only heat one bottle, but if you have twins or twins, you will be interested in purchasing one that allows you to heat two bottles at the same time.

  • Universality

It is advisable to buy a universal model that is compatible with any brand and size of bottle because you may use several different models during the first years of your baby’s life. Also make sure it is compatible with wide-mouth bottles and baby food so you can get the most for your money.

The most basic bottle warmers do not allow regulating the temperature and heating the bottles until reaching the recommended temperature which is normally around 37 º C.

If you want to get your money’s worth in the long term, it is better if the bottle warmer has additional functions that allow you to use it for more than just heating bottles. The bottle warmers that also sterilize the bottles and those that allow you to defrost and heat solid foods such as purees or baby food are very practical.

How Do You Use a Bottle Warmer?

Bottle warmers are very simple electrical appliances and generally work in a water bath. In almost all models, except for the more sophisticated models that use more complex techniques to heat the milk, all you have to do is place the bottle inside when the bottle warmer is unplugged, fill it with water and check that the bottle is completely left. covered with water. Then, turn on the bottle warmer, select the desired temperature and wait until the bottle reaches the correct temperature.

Some bottles have an automatic shut-off system when the desired temperature is reached, others have an acoustic warning system and in others, the manufacturer specifies in the instructions how long the bottle has to be left inside to reach the desired temperature. When the bottle is warm enough, remove it and check the temperature of the milk by pouring a few drops on the inside of your wrist.

The bottle warmer is especially useful when the baby is very young because it will not take long to warm the milk when the baby starts to cry. You just have to place the bottle in the device, turn it on and wait for it to reach the right temperature while you calm the baby by rocking it in your arms.

Keep in mind that if you are going to use it to heat baby food in addition to baby bottles, you will have to use a higher temperature. In addition, with baby food, it is advisable to stir the content from time to time to ensure that everything is heated equally. With bottles, it is not necessary because as milk is a liquid, the content is heated evenly, but with baby food, it is necessary because it could happen that the surface is hot but the content is still cold.

Usage Precautions

  • Although it is a very easy device to use, before using it it is advisable that you read the manufacturer’s instructions to ensure that you are using it in the correct way.
  • Almost all bottles have filling lines that mark the level to which the water has to reach depending on the size of the bottle used. Make sure not to exceed the maximum fill line to prevent water from running off the sides and damaging the appliance.
  • When you open it to remove the bottle, open the lid carefully to avoid burns from excess steam or hot water.
  • If you have had to go to work but continue to feed your baby with expressed breast milk with a breast pump, you probably already know that you can freeze or refrigerate it until it is time to give it to the baby. Keep in mind that to defrost it you have to follow a specific protocol to prevent the milk from losing part of its nutritional properties, so to do it correctly you must place it under hot tap water, in a fountain with hot water, or in a bottle warmer with defrost function. Remember that breast milk should not be thawed directly in a microwave at high temperatures because the milk would lose some of its antibacterial properties.

Cleaning The Bottle Warmers

As in bottle warmers, the food does not mix with the water, they are not devices that require complicated cleaning, but that does not mean that they do not have to be cleaned from time to time.

Although it is common sense before cleaning makes sure it is turned off and disconnected from the electrical current. Afterward, clean it well inside and out with a damp cloth and without using any abrasive product. In any case, read the manufacturer’s instructions carefully and follow them strictly to avoid damaging the appliance during the cleaning process.

Finally, you should check that no lime builds up. Keep in mind that it is one of the most common problems faced by products that use water, so if you start to notice that lime builds up, you can remove it using 60 ml of white vinegar mixed with 120 ml of cold distilled water. You can also use an anti-limescale product but, yes, in that case be sure to follow the manufacturer’s instructions carefully. Once the lime has dissolved, rinse it well with plenty of water and it will be ready for you to use again as soon as you need it.

  • If you express your breast milk with a breast pump, you should warm it carefully to ensure that the anti-infective capacity of human milk is not altered, that is, that heating it does not produce significant losses of immunoglobulins and nutrients.

Obviously, a bottle warmer that also allows milk to be sterilized will always be more expensive than a more basic one that only warms the milk in a water bath. Similarly, bottle warmers that include fruit juices, a water meter, and a glass for juice will also be much more expensive than other more basic models that do not have as many additional accessories.

  • How to choose the best bottle warmer?
