The Best Bottle Sterilizer And The Best Bottle Warmer

When looking after your baby, you want to be extremely careful. Babies are very vulnerable to both chemicals as well as illnesses. This is because they have not been able to build up an immune system that is capable of fighting off even the most common diseases around. Due to this very reason, it is extremely important to make sure that you are buying the best, most trusted products out there for your baby.

Buying the wrong products can not only alter the health of a baby, but it can also have lifelong effects on it as well. These are just a few of the many reasons why you should be looking hard to find the best bottle sterilizer and bottle warmer for your baby.

Why do you need a Baby Bottle Warmer?

You may be thinking to yourself, why would I buy a baby bottle warmer when I can just use the microwave? The thing is, if you are breast feeding and heat up your milk in the microwave; this causes the milk to lose a lot of its nutrients, and vitamins.

If you are feeding your baby formula, heating it up in the microwave can cause hot spots within the baby bottle that you might not notice. You can end up burning your baby’s mouth and due to the fact babies are so sensitive, it can go even further and you could end up burning their stomach.

There are multiple benefits to having a baby bottle warmer. The warmer will consistently bring the milk (whether it be formula or breast milk) up to the same temperature every time. You don’t have to worry about burning yourself, or burning your baby.

Some baby bottle warmers are even portable allowing you to take them with you wherever you go. Some versions can be charged using cigarette lighters, outlets and even batteries.

Why do you need a bottle sterilizer?

You may be wondering what the purpose of a baby bottle sterilizer is, when you can just buy a few baby bottles and throw them into the dishwasher. The problem with this scenario is dishwashers aren’t always the most reliable cleaners in tight spaces such as inside baby bottles.

There are plenty of benefits to having a baby bottle sterilizer. You will no longer have to worry about the harmful bacteria produced by your milk or formula as you know that the baby bottle will be clean each and every time.

What to look for in a bottle sterilizer and bottle warmer

When looking for a baby bottle sterilizer and dryer, there are a few things that you should make sure you are taking into account. Having a look at bottle sterilizer reviews as well as bottle warmer reviews can give you an amazing inside look into what the product is actually like; by real people who have actually bought it and tried it.

If a lot of people have purchased the product a quick scroll through the reviews will likely give you a fair amount of useful information. Things such as price, quality, design, purpose, and faults of the product all get talked about in the reviews.

What are my options for a baby bottle warmer?

There are a few different kinds of bottle warming options out there and each of them have their own advantages. Whether you are looking for the fastest bottle warmer or a universal bottle warmer so that you can warm other things; there are options available.


The main disadvantage with this option is that sometimes they have heating issues, and you could run out of power when you need it. The power issue is due to most of them being a battery operated bottle warmer, some are also heated using boiled water.

Plug in:

Generally the most reliable baby bottle warming option. These are a lot less likely to break down on you. In some models they can overheat and you have to wait until they cool down again, also it is less portable and more of a hassle to take with you if you are going somewhere.


These models can store cold milk in one section, and heat up your milk in the other. The main disadvantage to this system is that they are a lot more technical and can often be confusing.

Once you get the hang of how much water you need to use to heat up the milk, these are wonderful bottle warmers with the added bonus of a mini milk fridge.

What are my options for a baby bottle sterilizer?

There are many options when it comes to a bottle sterilizer. Depending on whether you are feeding your baby formula or breast milk, you may prefer one over the other. Carefully read the options below; then hopefully you can make a better educated decision on what kind of baby bottle sterilizer is the best option for you.

Cold water sterilizers:

For this option, you will need to purchase sterilizing tablets or liquid. You mix these in with cold water and then soak your baby bottles in the liquid for at least 30 minutes while the bacteria is being removed. After taking out the baby bottles you must then rinse them with recently boiled water (boiled to remove bacteria) so that the baby bottles will no longer have as much of a “clean” taste to them.

The one major disadvantage to this method is that the “clean” taste left behind by the baby bottle sanitizer is often hard to get rid of and it may turn your baby off of using the bottle.

Microwave sterilizers:

The big bonus to microwave sterilizers is that they require no chemicals or any rinsing. If you leave the microwave sterilizer closed, your baby bottles will remain sterilized for up to 24 hours. Generally microwave sterilizers take anywhere from 2-8 minutes depending on how many watts your unit has.

The one major disadvantage to this method is that you can’t sterilize metal (think baby spoons, metal rings on baby bottles etc).

Electric steam sterilizers:

Generally considered as the most convenient way to sterilize, due to there being more room available. Electric steam sterilizers involve just plugging into the wall and waiting anywhere from 5-15 minutes for the job to be complete.

The major disadvantage of these units is that they are generally more expensive and require more electricity to use than the other sanitization methods that are on the market.

So which brand of bottle warmer should I get?

Luckily for you we have gone through some of the companies that make the best bottle warmers, the breakdown of the electric machines that these companies make are below:

Munchkin bottle warmer:

This first plug in model weighs a modest 1.4 pounds. It uses steam to heat milk as well as baby food, quickly and evenly. It does not use microwave power and therefore assists in preventing losing the nutrients contained within the milk or food that is being heated.

This machine has an automatic shut off system so you don’t have to worry about leaving it plugged in. It also comes with a measuring cup so you can measure out the precise amount of water that you need in order to heat up the bottle.

Philips Avent 3-in-1 electric steam sterilizer:

This sterilizer is another one that is a great value for your money. The sterilizer completes a cycle in just 6 minutes. One downside to this sterilizer is that after a cycle is complete, you can’t use the sterilizer for at least 10 minutes because it has to cool down from the previous cycle first.

This sterilizer is advertised to kill 99.9% of bacteria and offers a variety of size configurations such as small which can be used for cup lids, pacifiers etc. Medium, which can be used for forks, spoons, small plates, breast pumps etc.

In case you have any questions on bottle sanitizing, or bottle warming; here are some answers to some of the frequently asked questions:

How do I know if my bottles will work for the bottle warmer/ bottle sanitizer?

The best way to find out if your bottles are going to work for a particular sanitizer, or a particular bottle opener is to read reviews on the products because this is basically the major topic in discussions on these products as people try to use them to do all sorts of different activities.

You can even post a comment yourself and ask someone if a particular item will work with the machine and it is very likely that you will get a response. If you are still having troubles you could either buy one of the largest ones available, so you can be sure that it will work; or you can contact the manufacturer directly and ask them.

How do I know if I am paying a reasonable price for what I am getting?

It is important to do proper research and decide what is best for your unique situation. You need to decide important questions such as: do you need a portable unit? Does the unit need to be a certain size?

How much can you afford to spend? Is the extra features that you get with a more expensive bottle warmer or bottle sanitizer worth the extra cost? These are all questions you need to ask yourself before you can decide on what a reasonable price is for you.

Is it safe to buy products off of Amazon?

It is a good idea to make sure you are buying from a reputable seller off of amazon before you purchase your product. If you purchase from amazon directly you can be sure that the product is safe to buy.

Sellers with thousands of reviews and high percentage ratings are also safe to buy from. Do your research before purchasing anything online and you shouldn’t run into any problems.

Are bottle sterilizers necessary?

Keeping your baby bottles sterilized is a great way to reduce the risk of your baby becoming sick. You can also be assured that your bottles are clean, chemical free and will not be harmful to the baby in any way.

How to clean a bottle warmer?

If you are unsure of how to clean a bottle warmer, there is likely a manual that came with your unit that explains what needs to be done in order to clean the unit. In general terms though, taking apart the unit and cleaning each piece that comes into contact with you, or anything that you put into the bottle warmer is a good idea.

This way you can be reassured that no old grime or residue is getting in your baby’s food or milk.

How long should I be warming up my baby’s food and milk for?

There is no specific age in which you have to stop warming up your baby’s milk and food. Your baby is its own human being and may prefer cold milk, or it may prefer taking it warm because it is closer to its own internal temperature.

As for food, depending what you are feeding them you may want to warm it up. .Just think to yourself how you would rather eat it, your baby probably thinks fairly similar to you.

Are bottle warmers safe for breast milk?

It is completely safe to heat up breast milk using bottle warmers. Just remember that if you decide to heat up your breast milk in the microwave, or boil it, it can destroy antibodies, vitamins and minerals that make the breast milk so healthy.

Most bottle warmers can also be used to heat up other things such as hot chocolate, coffee, tea, and baby food. Make sure you read the product description as well as reviews before assuming that the product does something that it might not do.

Which bottle warmer works with Medela?

If you are worried which bottle warmers work with Medela make sure you contact the manufacturer; you can also find answers to questions like these if you look in the reviews section underneath the product that you are looking to buy. The larger the sanitizer or bottle warmer, the more likely it is that your Medela products are going to be compatible with it.

How long do bottle warmers take?

Generally a bottle warmer doesn’t take very long to start working. If you get a portable version rather than a plug in version, they often take longer to heat up due to the fact that their power source isn’t as large. If you are looking for it to be done as soon as possible, you may want to consider that the purpose of this device is to make things warm for your baby, but not too warm so that they get burnt.

Being patient if the health and safety of your child is at risk shouldn’t be too big of an issue. In saying that, some bottle warmers do work faster than others and you can be sure to choose one of the quicker ones.

How to clean a bottle sterilizer?

How often should I get new baby bottles?

It is important to maintain your bottles so that they are in good sanitary condition. If you are unable to get them clean due to any mould, calcium build up, or you notice the bottle changing colour; it is important to get new bottles as the only thing you are potentially harming is your baby’s health.

Should I feed my baby formula, or should I breast feed?

This is often a hugely debated issue and it definitely comes down to personal choice. You are more than capable of feeding your baby your very own milk. Animals do it in the wild, humans can safely do it too. There are tons of nutrients, vitamins and healthy minerals contained within breast milk, but they also put a lot of these into baby formula.

Depending on whether or not you care about money, breast feeding is also the free option of the two. Formula is fairly expensive and you are bound to use more than one container of it over the course of your baby’s growing.

If in doubt over what you should use, make sure you do plenty of research into both options, as well as look at all the different formula options because they don’t all contain the same things inside them.

How often should my baby be eating or drinking?

Generally, babies will let you know if they are hungry or thirsty. If they are crying, likely they are tired, hungry, thirsty, hurt, or want some attention. If you get into a routine with your baby they will start to get an idea of when feeding and drinking time is.

Just remember that your baby is a human being. If they had a really deep sleep and sweat a lot, then they might need some extra milk. If they rolled around or had a temper tantrum, they might have burned some extra calories and will need some extra food in their body in order to make up for that.

I am scared some of these sanitizing machines/ bottle warmers are not chemical free, what do I do?

Look for specific bottle warmers and sanitizers that are both FDA approved and BPA free. If there is no information regarding these things, you can contact the manufacturer and they will tell you what the product is made from.

It is completely understandable that you want to know what your baby is being exposed to, so don’t feel bad phoning a company or expressing concern with regards to things like this. You are just being a good parent.

Hopefully you now have a better understanding of Baby bottle sanitizers and warmers. There are a ton of options out there and it can be very hard to narrow them down. Just remember to think about your own unique situation and when and where you are going to use them.

For instance, deciding whether you need a portable device or a plug in unit will have a huge impact on the price as well as the features of the product. When in doubt, get a second opinion.

Remember that anyone who is a parent has gone through almost all of the same problems that you are going through. Hope that this article has got you thinking, and that it will help you better decide what is best for you, but, most importantly what is the best for your baby.
