Depending on whether your baby is particular about the temperature of their food your answer might be a 'yes' or a 'no'. It could even be a 'maybe' or an 'I don’t know' if you are not sure of how these things work.

The easiest way to warm a bottle of course, is to put it in a pot of boiling wateror even put it under running hot tap water.Simple as it may seem, it can take a lot of time and your attention, not to mention under or overheating.

Bottle warmers can simplify your job by heating up baby's formula, milk or food quickly to the right temperature with a dedicated device. The warmer is always available unlike the pot which is probably in the sink just when you need it.

If you exclusively pump and breastfeed your baby, frozen milk is inevitable. The whole routine of thawing and warming can be laborious, not to forget that you should not heat breast milk to very high temperatures as it will deplete its nutrients and antibodies. For the same reason, microwave should not be used for breast milk.

Whether a bottle warmer is absolutely necessary or not is an entirely different topic altogether, but the fact remains that many families use it and swear by it. In fact, nothing can be more handy than a quick way to warm the milk at night when you have a hungry baby waiting and most certainly wailing too!


There is no rocket science behind how bottle warmers work. It is as good as you putting your bottle in a hot water bath, except that you don't have to stand by the kitchen counter and keep swirling that bottle every now and then.

Most warmers use either a water bath or steam to heat up a bottle of milk. Each method comes with its pros and cons.



A water bath allows for gradual and gentle heating while steam achieves higher temperatures in a short period. For this reason, a water bath is good for breast milk as it should not be heated to high temperatures.

Even otherwise, steam can be quite risky as it can cause scalding, burns and even hot spots. The water bath might be slower than steam but the possible risks while using steam far outweigh the speed of heating using the water bath method.


Every parent out there who has used a plastic bottle knows what the acronym BPA stands for. There is also enough knowledge about plastics and the leaching effect of heat on them. So as a parent, it's quite natural for you to be concerned about the safety of these gadgets.


Bottle warmers are much safer than your microwave which has the risk of scalding due to overheating and hot spots as a result of uneven heating. Most warmers rely on either steam or water bath as the method of heating which is still hot enough to cause reactions.

This is why the plastics used in the making of the warmers should be free of hazardous chemicals like phthalates, lead, latex or BPA. What's more important is that you also choose the bottles and bags that are free of these chemicals.

No matter what the method of warming, it is wise to check the temperature of the milk on the back of your hand before feeding your baby. After all, gadgets cannot replace humans.


Though some may argue that a bottle warmer is a waste of money, it is one of those products, the benefits of which can be felt only after using them.

Bottle warmers have the following advantages.

  • Consistent - Warmers ensure consistent and uniform heating without hot spots
  • Convenient - You can have them right beside your bed and even take them along on your trip
  • Multi-functional - Warmers using steam can also be used to sterilize bottles and pacifiers


The best way to start would be to make yourself aware of the different types of bottle warmers available in the market. There is always one that fits your equation.

  • Standard electric baby bottle warmers: A simple device that heats up one bottle at a time. Just fill it up with water, place the bottle and turn it on.
  • Feeding system bottle warmers: In addition to the function of a standard warmer they allow bottles to be kept ready for subsequent uses.
