Do I Need To Sterilize My Baby’s Bottles?

Sterilizing bottles isn’t a necessity, but it’s a step many mothers still like to take. It’s easy, and it cuts back on the number of germs your baby is introduced to, and that’s always a good thing in my book. I know I can’t wrap my children in bubble wrap and keep them safe from everything, but if sterilizing bottles even prevents one illness, I think it is time well spent.

A baby’s immune system is fragile for the first year. When you’re a new parent, it feels like germs are everywhere and there’s nothing you can do to cut back on the exposure to some of those germs — people love to touch and hold your baby. You don’t relish the idea of being labeled as the paranoid freaky mom who won’t let people around her baby, so you try to ignore your inner voice that is cautioning you about all those germs.

Germs everywhere

When you’re a new parent, it feels like germs are everywhere

If you can’t stop all the germs caused by the touchy-feely types who are around your child, at least you can make sure her bottles aren’t making her sick.

When Can You Stop Sterilizing Bottles?

There’s no point in sterilizing bottles once a baby becomes mobile or begins to grab at everything she sees (source).


When your child is old enough to make the connection that she can grab things and put them in her mouth, she’s going to be introduced to more germs than will possibly accumulate in her bottles.

After you stop sterilizing, though, you should be certain that you’re doing a top-notch job of cleaning the bottles and nipples. And if your baby has an illness (source), you should sterilize her bottles until she is healthy again. You don’t want to reintroduce any germs to her recovering immune system.

The Different Ways You Can Sterilize a Bottle

There are several recommended ways to sterilize bottles and nipples.

The way many of our moms sterilized our bottles was to boil them in water on the stove in a pan. This is still the cheapest way to do it, but I’ve always avoided that method. I used plastic bottles, and I didn’t like the idea of boiling them because I wasn’t confident that harmful chemicals wouldn’t leach out as a result of the boiling water. Times have changed since we were babies, and there’s a simpler way to do it now.

You can use microwavable bottle sterilizers or electric steam sterilizers. They both use to steam to sterilize the bottle.

UV bottle sterilizers are one of the newest methods for sterilization. These units use ultraviolet light to kill germs. If you go this route, be prepared to pay dearly – these units can cost several times more than what you’ll pay for an electric or microwave sterilizer. The cost puts them out of reach for many people who aren’t prepared to skip a car payment just to be able to afford a bottle sterilizer.

What Should I Look For In A Bottle Sterilizer?

  • Ease of use: Electric baby bottle sterilizers should be simple to operate – if you find yourself scratching your head over the instructions or there’s so many buttons that you’re sure you’ll never figure out the unit you’re looking at, you should move on in your search. There’s too many great choices out there to settle for something that’s less than ideal for you.
  • The size: You want the unit you buy to be large enough to suit your needs. Mothers who are breastfeeding and only use bottles if they are away from their baby will be able to get by with a small unit that just handles a couple of bottles.
  • How many bottles can it sterilize at once: Women who opt to feed their babies formula will sterilize bottles frequently throughout the course of the day if they buy a small unit. So they will want to look for a bigger sterilizer that can handle a larger number of bottles to cut down on their daily work.
  • The cost: If your cash flow is smaller now that you’ve become a parent, the cost will be an important consideration. Microwave sterilizers are usually cheaper than the other types on the market.
  • Does it dry: Microwave sterilizers work quickly, but the bottles are left wet, and they’ll have to be dried after they are taken out of the microwave. That adds an extra step to your workload.
  • Space in your kitchen: Some moms might like that microwave sterilizers won’t require any space on their kitchen counters. They can be stored in a cabinet until you need them and they don’t need an outlet to work. If you opt for an electric sterilizer, you’ll have to make some room on your counter for it.
