As we are aware, ensuring the hygiene of baby bottles and other accessories becomes crucial during the first 6 months when a child's immune system is still vulnerable. Mothers should pay attention to sterilizing the baby's bottle before breastfeeding, even for newly purchased ones.
Let's explore the proper ways to clean baby bottles with Mytour to ensure comprehensive health for both mothers and babies.
1/ Hygiene for newly purchased baby bottles
When using bottles for newborns for the first time, mothers need to clean the bottles with a brush and soapy water. Since they are newly purchased, mothers should remember to scrub thoroughly. Next, immerse the bottle in boiling water for about 5-10 minutes. Be cautious not to let the bottle touch the pot's body as it is very hot and may cause the bottle to melt or deform. Afterward, take out the bottle and expose it to direct sunlight until completely dry.
2/ Hygiene for baby bottles used multiple times
After each feeding, mothers must be extremely careful with the hygiene process. Following a thorough cleaning of the bottle and nipple with cold water (ensure to spray water through the nipple multiple times to ensure cleanliness), mothers commence the bottle sterilization process. Bottle sterilization can be accomplished through the following methods:

Properly maintaining baby bottle hygiene
- Using chemical disinfectant in cold water (chlorine): While it may take more time (over 30 minutes) and leave an odor that could make the baby uncomfortable, this is a convenient method and completely ensures safety, even with silicone bottles.
- Boiling: Although cost-effective, it may compromise the quality of the bottle and could release toxins from the plastic.
- Sterilizing with steam in baby sterilizing machines (available in mother and baby stores): This method is quite popular as the steam machine will autonomously complete the task within a specific time frame (10 – 15 minutes) and at a certain temperature, ensuring the quality of the bottle.
- Microwave sterilization: This method is also quick, convenient, with stable time and temperature, but not applicable to glass bottles.
3/ Hygiene Timing
Mothers should only sterilize rigorously in the first 6 months of the baby's life because, at birth, the baby's body is very delicate, and their immune system is weak. Therefore, all utensils related to feeding should be thoroughly cleaned. However, once the baby reaches the 6th month, strict hygiene of baby bottles is no longer necessary as it may hinder the development of the baby's immune system to fight against diseases. Additionally, after 6 months, babies begin to explore the world and may put items within reach into their mouths.
Furthermore, parents should also note the following during the baby bottle cleaning process:
- How to Sterilize Baby Bottles?
When using a baby bottle for the first time, mothers need to sterilize it. The process of sterilizing baby bottles is quite simple. First, clean the bottle with a bottle-cleaning solution. Pour a sufficient amount of water into the dish rack, add some baby bottle cleaning solution to the water. Then, place all the baby bottles into the water and scrub them thoroughly.
Next, boil the baby bottles for about 5 – 10 minutes. Remember to pour water to fully submerge the baby bottles. Afterward, take the bottles out and place them in a clean spot until completely dry.
- Sterilizing Baby Bottles for Infants – Is it Necessary?
For newborns, there are not only baby bottles but also numerous other items that need to ensure safe hygiene, such as teething toys, pacifiers, breast pump funnels, bowls, and feeding spoons. Compared to the immune system of older children and adults, newborns lack immunity, requiring a very high level of cleanliness, often referred to as '100% germ-free.' Hence, the familiar concepts of 'Sterilization' and 'Disinfection.'
To clean baby items, 'Sterilization' is the final stage after they have been thoroughly cleaned with baby bottle cleaning solution and rinsed with clean water. The child is only truly safe when mothers diligently sterilize baby bottles.
- To Sterilize or Not with Boiling Water?
This is the most classic method. Mothers don't need to buy anything; just a steamer with sufficient capacity to boil items for 20 minutes. However, this method is not as simple and convenient as people think. When sterilizing this way, mothers always have to monitor the process. The baby bottles must be fully submerged in water, and the boiling time must be a full 20 minutes. The pot becomes hotter than 100 degrees Celsius, so if the baby bottles are placed close to the pot, they are prone to melting. If left unattended on the stove, all items may warp. After sterilization, leaving the items uncovered or soaked in water for too long creates conditions for bacteria to return.

Ensuring Safe Storage Hygiene for Mother and Baby
- At What Age Should You Stop Sterilizing for the Baby?
This depends on each child, as each baby has different immunity. According to pediatric experts, the immune system of children under 6 months is still delicate, making them susceptible to digestive disorders if the baby milk is contaminated. However, mothers should not be overly meticulous. Continuous sterilization beyond 6 months hinders the baby's immune system development to fight diseases. Sterilization at this stage is also futile, as babies begin the stage of exploring the world by putting everything within reach into their mouths.
- Safely Bottle-Feeding Your Baby
Breast milk is always maintained at an optimal temperature for easy consumption by the baby. However, as the baby grows a bit older, additional formula feeding becomes necessary. This is when mothers need to pay special attention to issues related to baby bottles to ensure healthy and safe meals for the baby.
- Choosing a Safe Baby Bottle
Choosing between glass and plastic bottles for the baby is a common dilemma for many mothers. Glass bottles are typically heavier than plastic ones but are safer as plastic bottles often contain the unsafe chemical Bisphenol A (BPA), which can adversely affect the reproductive and brain development of infants. Therefore, if choosing a plastic bottle, mothers should carefully check if it contains BPA. For glass bottles, mothers should select a lightweight option with the ability to retain the milk's warmth for a longer duration.

- “Regulating” the Temperature of Baby Bottles
The first thing to remember is not to leave the baby's bottle in the microwave. Overheated milk can make it difficult for the baby to drink or, when consumed, may cause discomfort in the baby's throat. Regarding the temperature of the baby bottle, mothers should ensure that the milk is served at a cool or ambient temperature. Ideally, before feeding the baby, mothers can immerse the bottle in cold water for about two minutes to lower the bottle's temperature.
If the milk is cold, mothers can use a wider cup or bowl, pour hot water into it, and place the baby bottle inside to gradually warm it up.
- Check the Milk Temperature
Many mothers believe that the milk temperature for the baby is suitable and hesitate to check it before feeding. However, before feeding the baby, mothers should double-check the milk temperature by dropping a few drops on the wrist. If the milk is warm, mothers can feed the baby right away; if it's too hot, mothers need to let it cool down. In case the milk is too cold, mothers should place the bottle in warm water for a few minutes as instructed in step 2 before feeding the baby.
- Clean the Nipple
The nipple part of the baby bottle is often made of silicone or rubber and is silver-coated to resist bacteria. However, before preparing milk for the baby, mothers need to clean the bottle and nipple thoroughly with baby bottle cleanser and boil the nipple in hot water for about 3-4 minutes. This is the most susceptible part of the baby bottle to bacterial invasion and can affect the baby's immune system. Additionally, mothers should replace the bottle nipple approximately every three months to ensure cleanliness and hygiene for the baby's feeding.
We hope that our article can assist mothers in properly cleaning baby bottles for their children, making the daily task of bottle hygiene quick, highly effective, and safe.
