Nevertheless, what remains constant is the need to provide them with clean baby bottles and sterilized equipment. This is where the coin turns and the buried question of – how to sterilize baby bottles comes into play!

Should one use soap and hot water? Follow the manufacturer’s list? Or, simply a clean towel? To help you out with these questions, we have curated this article that includes the best cleaning and sterilizing ways for a baby bottle, be it glass, plastic, or even silicone. So let’s get started!

First Things First, When and How To Sterilize The Baby Bottles?

In addition to the traditional cleaning methods, sterilizing baby bottles is a step beyond that provides extra protection against germs. This step is initiated as soon as you purchase a bottle that needs to be sterilized before it enters the mouth of the little one to ensure the baby’s health and safety.

In most cases the first sterilizing is the all-in-all, however, there are a few incidents that might call for another sterilizing process, such as:

1) If the baby's bottle is borrowed or is second-handed:

Keeping in mind the requirements of the baby, there are a few parents who might hit the consignment shops or borrow baby bottles from a friend. This is one critical situation where you must make sure to sterilize the bottle before giving it to your child, even if it’s not used. Additionally, it is important to sterilize bottles, even if they belong to an older sibling.

2) If the baby was sick:

This is no news, rather a priority and a must-do. It was no fun to have your little munchkin get sick, therefore, it’s best to avoid the risk of re-infecting them again.

3) If the baby was born prematurely or has any health concerns:

The Centers for Disease Control and Prevention (CDC) has made it a mandated step to sterilize bottles, especially when the baby was prematurely born or has a weakened immune system.

4) If there is no access to clean drinking water:

This is rather self-explanatory! Clean drinking water equals good health and vice-versa. This is also true in case you keep traveling since there is a chance of unclean water. Here, it’s best to sterilize the baby’s bottles often, or once daily to avoid the buildup of harmful microbes.

How Often And When Do You Need to Sterilize Baby Bottles?

In a fortunate situation where there is a good supply of clean and fresh water that doesn’t come from the well, you are good to go. However, if not, it’s important to sanitize bottles often to prevent harmful germs from entering your baby’s mouth.

On the flip side, some damages can be made due to regular sterilizing of the baby bottles that can also allow the chemicals to leach into the baby’s milk, especially if it has BPA. This is why the Food and Drug Administration (FDA) banned the use of bisphenol A (BPA) in baby bottles in 2012, which could potentially damage and impact the infant’s development.

Having said that, the number of times you sterilize a baby bottle is up to you, but make sure to not over or under it. You can also choose to sterilize the bottle in a dishwasher with hot water and a heated drying cycle or sanitize the feeding items once daily, as per the claim by CDC.

When to stop?

  • As per the guidelines by CDC, If you sterilize the baby’s bottle regularly, it’s ok to stop as soon as the baby is 3 months old, keeping in mind the developed immune system of the baby
  • Stop in case there is any damage, cracks, chips, or the bottles leave a strong odor

Note – Make sure to replace the bottle nipples if there is any noticeable wear and tear to prevent choking.

How To Clean Baby Bottles?

Cleaning the bottle and the bottle parts is a mandatory process, regardless of whether you choose to sterilize bottles or not. The cleaning needs to be done after every feeding, if not the infant could be vulnerable to infections by viruses, bacteria, parasites, and fungi, leading to unwanted illness.

Germs can easily and quickly develop if the bottles aren’t clean in the right manner. This is why it is very important to make sure that the bottle and the equipment are washed with hot soapy water to remove the harmful germs. Here’s how:

  • Run the bottles on a hot-water cycle and heated drying cycle. Or select the sanitizing setting

  • First, wash your hands
  • Separate the bottle parts and rinse each piece under hot or cold water to remove the milk particles
  • Fill the sink with hot water and soap and then scrub the bottles using the bottle brush
