Sterilizing baby’s bottles – the safe easy ways

How to sterilize baby bottles?

It’s important to know how to sterilize baby bottles and all your baby’s feeding equipment (bottles, teats, breast pump, etc) until they are at least 12 months old. This will protect your baby against infections, in particular diarrhea and vomiting.

Before sterilizing, you need to:

Clean bottles, teats and other feeding equipment in hot, soapy water as soon as possible after feeds.

Note: there are special dish detergents for babies, which are mild and do not contain harmful substances.Steam Sterilizer - how to sterilize a baby bottle i babyland

Use a clean bottle brush to clean bottles (only use this brush for cleaning bottles), and a small teat brush to clean the inside of teats. You can also turn teats inside out and wash in hot soapy water. Don’t be tempted to use salt to clean teats, this can be dangerous for your baby.

You can put your baby’s feeding equipment in the dishwasher to clean it if you prefer. (Putting feeding equipment through the dishwasher cleans it but doesn’t sterilize it.) Make sure bottles, lids and teats are facing downwards. You may prefer to wash teats separately by hand to make sure they are completely clean.
Rinse all your equipment in clean, cold running water before sterilizing.

The advice above applies to all your baby’s feeding equipment, and whether you are using expressed breast milk or formula milk.

Different methods to sterilize a baby’s bottle?

There are several ways you can sterilize your baby’s feeding equipment. These include:

  • steam sterilizer (electric sterilizer or microwave)
  • cold water sterilizing solution
  • boiling

Let’s have a look at how to sterilize baby bottles with each of the methods.

Steam Sterilizer (electric sterilizer or microwave)

Make sure the openings of the bottles and teats are facing downwards in the steam sterilizer.
Manufacturers will give guidelines on how long you can leave equipment in the sterilizer before it needs to be sterilized again.

  1. Clean bottles, teats and other feeding equipment in warm, soapy water
  2. Add the recommended amount of water to the sterilizer.
  3. Load the sterilizer.
  4. Place the nipples, nipple rings, and caps inside. …
  5. Put the cover on.
  6. Turn on the machine.
  7. Remove the bottles when the cycle finishes.

It’s important to follow the manufacturer’s instructions, as there are several different types of sterilizers.

Cold water sterilizing solution

Follow the manufacturer’s instructions. Leave feeding equipment in the sterilizing solution for at least 30 minutes.
Change the sterilizing solution every 24 hours.
Make sure there are no air bubbles trapped in the bottles or teats when putting them in the sterilizing solution.
Your sterilizer should have a floating cover or a plunger to keep all the equipment under the solution.


Sterilizing by boiling

Make sure that whatever you want to sterilize in this way is safe to boil. Boil the feeding equipment in a large pan of water for at least 10 minutes, making sure it all stays under the surface.
Set a timer so you don’t forget to turn the heat off.
Remember that teats tend to get damaged faster with this method. Regularly check that teats and bottles are not torn, cracked or damaged.

After you’ve finished sterilizing

It’s best to leave bottles and teats in the sterilizer or pan until you need them.
If you do take them out, put the teats and lids on the bottles straightaway.
Wash and dry your hands before handling sterilized equipment. Better still, use some sterile tongs.
Assemble the bottles on a clean, disinfected surface or the upturned lid of the sterilizer.
