While microorganisms play a beneficial and essential role for humanity, their activities can also pose many health hazards, especially to young children. During the first 6 months of life, a baby's immune system is still fragile, with weak resistance, making them susceptible to stomachaches and diarrhea if they consume contaminated milk. Therefore, sterilizing all items and utensils related to feeding the baby, especially baby bottles, is absolutely essential.
Sterilization involves the eradication of microorganisms, cells, and viruses through various physical and chemical methods.
Proper Guide to Cleaning Baby Bottles Correctly
+ Disassemble the components of the baby bottle.
+ Thoroughly clean each component. Specialized cleaning solutions and bottle brushes can be used. Nipples should be hand washed to avoid scratching. Mothers can spray water through the nipple to clean the nipple holes thoroughly.
+ Place bottle parts on a drying rack to air dry. Avoid exposing nipples to direct sunlight as it can deform them.

Current Popular Method of Sterilizing Baby Bottles
Today, there are 4 common sterilization methods used by Vietnamese mothers:
Sterilizing Baby Bottles with Boiling Water
The heat and moisture of boiling water easily kill viruses, bacteria, and fungi. Boiling water for 10 minutes can destroy the nutrient cells and spores of microorganisms. Therefore, this is an effective method for mothers to sterilize bottles for their babies.
Place all bottle parts in a pot of boiling water, boil for an additional 15 minutes. For nipples, boil for only 5 minutes then remove. Mothers should use tongs to avoid burning their hands.
For this method, mothers should select a dedicated pot solely for sterilizing baby bottles, avoiding using it for other purposes.
This method has the advantage of being simple, easy to do, and cost-effective for mothers. However, it also brings many inconveniences, especially the risk of damaging bottles from frequent boiling or increasing the likelihood of releasing toxins from bottle materials, which can negatively affect baby health.

Sterilization with Chemicals
Sterilizing with chlorine is considered the simplest method yet highly effective in treating and disinfecting water to prevent diseases caused by contaminated water sources. At water treatment plants, before water is supplied to households, a sufficient amount of chlorine is added to ensure the water source remains free from bacterial contamination.
Mothers dissolve chlorine tablets in cool water in a sterilizing basin. Then, immerse all bottle parts in the disinfectant water, ensuring no air bubbles remain in the equipment. Soak for approximately 30 minutes, then rinse with boiled water to cool and air dry.
This method may be time-consuming and labor-intensive, and the chemicals may leave an odor that can make it unpleasant for babies to feed. However, it is indeed a safe sterilization method for babies.
Sterilizing with Steam Sterilizer
After cleaning the bottle parts, place them in the sterilizing steamer, add water according to the instructions, and switch on. Sterilization will be completed in about 10-15 minutes.
This method not only ensures sterilization but also saves a lot of time for mothers. However, mothers need to invest in a steam sterilizer to apply this method.

Sterilizing with Microwave
Disassemble the bottle parts, clean them, then place all in a water-filled sterilizing box and put the box in the microwave for about 2 to 5 minutes before removing.

(Note: Mothers need to be cautious when using the microwave. It is essential to check carefully before using it. If the bottle contains milk, food, or a sealed lid, never put it in the microwave).
