As the list of products pile up on your baby registry, you might be wondering whether you really need all of these items. After all, people have been having babies since the dawn of time — well before stroller wagons and fancy shmancy formula makers were invented — and they seemed to survive just fine. 

While it’s true that there’s a seemingly endless amount of options available at your fingertips when it comes to just about every single category in the caring-for-baby sphere, there are a few items that might seem excessive but wind up saving you serious time (which, most parents can agree, is priceless). 

One of those items is the baby bottle sterilizer. Because who wants to have to boil a pot of water (and wait for it to reach the perfect temperature) every time you have to sterilize your baby’s bottles? You don’t need a big pot at the ready with this list of best baby bottle sterilizers. The best sterilizer for baby bottles makes the job easy— it can be a small counter-top unit or even your microwave. Small things, moms, small things.

Do you really need a baby bottle sterilizer?

According to Lauren Crosby, MD, FAAP, and Bobbie Medical Advisor, you will need to sterilize your bottles if your baby was born prematurely, has a compromised immune system or is younger than three months old. With any new bottles, nipples and caps, you’ll want to sterilize before the first use.

Additionally, if you plan on traveling during that first year, a sterilizer for your baby bottles might come in handy should you be staying at a hotel that doesn’t come with a kitchen. So, needless to say, a bottle sterilizer just might become your new best friend.

Which is the best bottle sterilizer?

There are so many out there to choose from, each with their own unique set of features, so it pays to spend some time looking over what each sterilizer offers to determine what might work best for you and your family, especially during those early, and often sleepless, days and nights of parenting. “There are many ways to sterilize baby bottles— from boiling water to electric bottle sterilizers,” says Dr Crosby, “Find the method that works best for you.”

What is the safest way to sterilize baby bottles?

Using a bottle sterilizer is a safe way to sterilize baby bottles because these machines are designed to kill up to 99% of bacteria and viruses from the bottles themselves. Another alternative is boiling the bottles in water on a stove. Simply disassemble the bottles, place them in a pot with enough water, bring the water to a boil and let it boil rapidly for 5 minutes or as directed by the bottle manufacturer. Remove from the heat and allow the water to cool before using sterile tongs to remove the pieces.

Tips for Choosing a Baby Bottle Sterilizer

Most sterilizers work in a similar fashion, but, of course, there is a wide variety available on the market today. Here are a few tips for how to choose the right baby bottle sterilizer for you — and what features to look for. 

  1. Make sure it’s the right capacity

Depending on your needs, you may require a bottle sterilizer that can clean multiple bottles at a given time — this is especially true if you have multiples. Also, if you plan on exclusively formula feeding, you will likely have more bottles that require cleaning than someone who is combination feeding.

  1. Check how long it takes to sterilize each bottle

A bottle sterilizer should save you time, so it’s a good idea to look into the length of each cycle on a given bottle sterilizer before purchasing it. Some high-tech bottle sterilizers can do their job in as little as a few minutes, while others might take closer to 15 or even 30 minutes to do a full clean. 

  1. Consider added features

Some sterilizers on the market today come with some cool added features, such as automatic drying and even added storage, which can come in handy if you’re short on counter space. Auto-shut off is another cool feature that can seriously come in handy, especially for sleep-deprived parents. 

Is UV or steam sterilization better for baby bottles?

There are two main types of bottle sterilizers: UV and steam sterilizers. Steam sterilizers use the more traditional method, using natural steam to kill 99.99% of potentially harmful bacteria. This type of sterilizer tends to fit more bottles, since the steam flows through the entire device, killing anything harmful in its way. 

UV sterilizers, on the other hand, use ultraviolet (UV) light to kill the bacteria instead of steam. While this method also works, it’s important to point out that, unlike steam sterilizers, UV sterilizers only work on the items in which the light is able to reach. This is why UV sterilizers tend to be smaller.

FAQ’s about baby bottle sterilizers

How often should you sterilize baby bottles?

You should always sterilize bottles when first using them, per the CDC — and, if your baby was born premature, has a weakened immune system, or is under three months old, you should be sterilizing at least once daily. 

Are baby bottle sterilizers safe?

Yes. Most sterilizers on the market today kill up to 99% of potentially harmful bacteria on your baby’s bottles when used properly. Just make sure you’re reading directions and changing out any necessary filters per the product recommendations. 

What can happen if I don’t sterilize baby bottles?

While older kids and adults can often fight off simple bacteria, babies are more vulnerable to foodborne illness due to their developing immune systems, so it’s important to sterilize per the CDC’s recommendations to avoid compromising your child’s health. 

At what age do you stop sterilizing baby bottles?

The CDC recommends sterilizing your baby’s bottles until they are 3 months old and longer if they are immunocompromised.  

How do you dry bottles after sterilizing?

Many of the sterilizers featured have a drying feature. If you’re using the good old boiling pot method, you still want to make sure your bottles, nipples and caps are dry. Setting them on a drying rack or hanging them from a drying tree is the easiest method to dry bottles after sterilizing.
