Why Should You Use a Bottle Sterilizer?

Why to Sterilize Bottles

As hard as you try, you’ll soon find out there’s not much you can do in the fight against germs and bacteria.

No matter how clean your home is, or how careful you are keeping your little one away from those nasty critters, babies are more prone to illness and disease.

Additionally, warm milk is also a breeding ground for bacteria, so it’s important to sterilize bottles, pacifiers, and latex or silicone nipples.



How Long Should You Sterilize Your Baby’s Bottle?

It is usually important during the first 12 months although some experts even suggest six months or as soon as your baby can put foreign objects in their mouth like your shoe, the dog’s tail or another baby’s pacifier.But even then, sterilizing all the feeding equipment once in a while won’t do any harm.


What Can Happen if You Don’t Sterilize Bottles? fact is, babies can pick up germs and bacteria from pretty much anywhere.

But if there were an easy way for you to reduce the number of them, you would do it, wouldn’t you?

The formula contains milk as well as other ingredients that are breeding grounds for viruses and parasites; cleaning the bottles and nubs (or nipples) well will prevent any unnecessary illnesses.




Deadly Germs

An unsterilized bottle could be a death sentence for a baby. According to, Gastroenteritis can cause vomiting, dehydration and if left untreated, death.

This is more prevalent in poorer countries where knowledge isn’t as commonplace and medical care not as readily available. We’re not immune to this, and that’s why it’s recommended to find the best bottle sterilizer for you little one.


How Does A Bottle Sterilizer Work?

Bottle Sterilizer Are QuickThe majority of sterilizers are simple to use. It’s a case of placing the bottle along with all the other bits into the sterilizer and switching on a button or putting it into a microwave, depending on the type you have.

Most are quick, can take a few bottles at a time and do the job well.




Different Ways of Sterilizing Baby Bottles

There are various ways to sterilize bottles, and any of these are effective. However, some are more convenient and less fuss.

1. Boiling water

Placing the bottles and nipples in boiling water for a few minutes is a tried and tested way of doing it. Most of us can easily try this at home.However, the heat is often too extreme and can damage or melt the feeding equipment. Also, it can be messy, and the nipples get unusable quite quickly doing it this way.

2. Steaming

This is the most common method and one that hospitals use most often.

You just need to place the items upside down in a container or chamber and leave the steam to do its thing. It’s quick, effective and is a gentle way of thoroughly cleaning the bottles and nubs.

3. Microwaving

This is probably the most powerful way of killing off any bacteria.

According to LiveScience, the radiation from the microwave and the heat from the steam work together to get rid of any pathogens, and they stay sterile for longer. The only thing downside is that, with this steaming method, you do need to have a microwave handy.


Tip for Saving Money

​Getting a bottle sterilizer that takes standard and wide-necked bottles is more versatile. Also, one that has space for bowls and cups will come in handy during the weaning stages. You can sterilize teething rings and other toys in the bottle sterilizer too.
