There are 4 ways you can sterilize your bottle-feeding equipment after you’ve cleaned it:

  • Boiling
  • Chemicals
  • Steam Sterilization
  • Microwave Sterilization.

If you’re breastfeeding and only need to sterilize a bottle occasionally, the boiling method may be a better choice.

It’s quite affordable than buying a steam sterilizer. If you’re bottle-feeding, then a steam sterilizer is needed.

Sterilizing By Boiling

This is the simplest and most reliable way to sterilize baby feeding bottle parts. To do this

  1. Put all parts of the washed bottle, including teats and caps in a large pot.
  2. Fill the pot with tap water until everything is covered. Ensure all air bubbles are gone.
  3. Now put the large pot on the stove and allow it to boil for 5 minutes.
  4. Allow the feeding parts to cool in the pot until you can take it out with tongs or clean hands without scalding yourself.
  5. Remember to shake off excess water. You do not need to dry the items.
  6. Store feeding parts you are not using in a clean, sealed container in the fridge. Always clean these containers with hot soapy water, and rinse thoroughly with very hot water daily. It is best advised to have at least two containers that you can alternate.
  7. Finally, use all equipment within 24 hours of boiling.

Sterilizing Using Chemicals

Be careful when using chemical sterilization. You can sterilize your bottles with an antibacterial solution. This can come in both liquid or tablet form.

The bleach must be diluted with water to make this safe for your baby. Remember, this must be prepared exactly as directed on the container.

Here’s how to sterilize your baby’s feeding bottle with chemicals:

  1. Ensure you follow the manufacturer’s guide carefully when preparing the solution. The right strength is required to kill stubborn germs in your baby’s feeding bottle.
  2. Completely submerge all bottles and feeding parts (teats and caps) in the solution. Ensure no bubbles are left in the bottles.
  3. Leave everything in the solution for the recommended time.
  4. Use tongs to remove the feeding parts from the solution. Before use, shake off excess solution, but you don’t need to rinse the feeding parts.
  5. Finally, store baby feeding parts in a clean, sealed container in the fridge or the solution.

Note: If you store baby feeding parts in the fridge, ensure you use them within 24 hours after sterilization.

If you leave parts in the solution, throw the solution away after 24 hours, then scrub the container and parts in warm soapy water and restart the sterilization procedure again.

Steam Sterilizing

Steam sterilizers are automatic units that cook your baby’s feeding parts at a temperature high enough to kill bacteria. This method is popular because they are cheap and works very effectively. Some of these steam sterilizers are designed to operate in a microwave.

  1. Place the clean bottles and feeding parts in the sterilizer.
  2. Ensure that there is enough space between each baby bottle, teat, and screw cap for proper circulation of steam all through the surface.
  3. Follow the manufacturer’s guide about how much water to add.
  4. Turn on and push the start button.
  5. Wait until the sterilization cycle has finished and the light goes off.
  6. Store all equipment you aren’t using in a clean, sealed container in the fridge.
  7. Ensure you use all baby feeding parts within 24hrs of sterilization.
