How to Sterilize Baby Bottles

Baby Feeding

The main reason for cleaning and sterilizing baby bottles is to keep them safe from bacterial infections which could lead to severe infections when the baby is still young, and immunity is low.

It is recommended that immediately you buy the bottles, sterilize the bottles, nipples, rings and the lids to ensure that they are free from germs. This is because when in the process of manufacturing, the bottles pass through many hands and contact with chemicals that are potentially unsafe for the baby.

Currently, there are various safe water sources, and many parents do not sterilize always but it’s still recommended that you keep sterilizing as often as possible, This is because the bottles keep on getting in touch with unclean surfaces that keep on collecting germs.

Why are bottles sterilized?

  1. When you notice that the immunity of the baby is low.
  2. When the water being used is from a supply that has contamination.
  3. When the baby was born prematurely.
  4. Babies who are less than for months old.

One may wonder what the difference between sterilizing and boiling is. Sterilizing is putting the bottles under high temperatures meant to kill germs while boiling refers to the process of regular daily washing using water and dishwashing soap.

Items needed for sterilizing the bottles;

  1. Pot – for boiling water
  2. Bottlebrush – to scrub the bottle.
  3. Nipple brush – Used for removing any milk or particles that are left sticking in the nipples.
  4. Stove – This is for providing the heat required for boiling.
  5. Tongs – To prevent your hands from burning when removing the bottles from the boiling water.
  6. Towel – Used to ensure that the nipples are completely dry.

Step by step process for sterilizing the bottles

  1. Washing- Before putting the bottles and the nipples in the boiling water, wash them thoroughly with dishwashing soap and ensure they are clean. Confirm that there are no milk particles in the nipple and case of any, remove them with the nipple brush.
  1. Once through with cleaning, submerge the bottles and nipples in a pot filled with water. Ensure they are fully covered such that when you start to sterilize, the whole parts will be completely worked on.
  1. Place the pot in high heat temperatures for boiling. The tap water should completely boil and ensure that once the water starts boiling, they stay in for about five minutes to ensure that germs are eliminated. A center for pediatricians known as the California Pacific Medical Centre recommends this.

Previous research has proved that bacteria cannot survive in boiling water for four minutes and this happens to be the reason for sterilizing them.

  1. Ensure you have tongs for removing the baby bottles from the boiling water and remove them from the pot once five minutes are over to prevent from burning your hands.
  1. Have a clean towel to place the nipples in it so that they dry completely and no chances of burning the baby with residual hot water once you are through.


Do not allow children in the kitchen because accidents happen very fast and they may burn in the boiling water. Ensure that the stove is placed a distance far from the reach of children.

Immediately you are through with boiling the water and sterilizing, remove the water and pour it into a sink that it may flow out and reduce chances of accidents.


Always ensure that you clean your hands to avoid contaminating baby bottles with germs.

Maintain a clean shelf for storing baby items. Do not at any time mix them with other kitchen utensils as they can contact germs and yet the baby is too young for strong immunity.
