Necessary Points That Should Be Considered When Sterilizing Baby Bottles

Before starting sterilization process, we should be careful about some terms. These terms are described below:

BPA Checking

BPA is such material that may cause bacterial growth. Plastics of bottles contain BPA, usually. If we heat the bottle to sterilize it can leach from bottle and mix up with baby food. This BPA causes baby growth problem. Many people heat bottles to sterilize it and so, they should be sure to find a BPA free bottle. Glass bottles are generally BPA free. However, you can also use sterilizer that make bottles BPA free.

Sterilizing New Bottles

Many people think of new bottles free of germs and wastes. But new bottles should be sterilized properly before starting its use. Because it may contain more germs than we think about it. This can be more dangerous for your baby. Sterilizing with a good sterilizer before using it is the best idea.

Be Vigilant for Sick Babies

For your sick baby or if your baby has recovered recently, you should be extra cautious. You certainly do not wish that your baby gets re-infect by germs.


Glass Bottles Also Need to be Sterilized

Within the instruction that is given with a glass bottle, a mother should sterilize that too. Glass bottles maybe BPA free but that does not mean that it is germ free. so, you should sterilize a glass bottle too.

Types of The Best Baby Bottle Sterilizers

There are a lot of baby bottles and different types of baby bottles in the market. You can choose as your preference. But if you have knowledge about the types of these bottle sterilizers, it would be good for you to choose the right one. You do not need to worry because we have select best baby bottle sterilizers for you and will describe about these in this article.

Electric Steamer Sterilizer

Like the appliance of your kitchen problems, there is good options to sterilize your baby’s bottle. The electric steam sterilizer is such that. You only have to plug on the machine and then you can do your work. After a while, you will get germ free bottles. In the electric sterilizer, bottle, and nipples are sterilized at high temperature. This high temperature destroys all the bacteria and germs. This machines dry out the bottles and nipples too. You just need to make sure that the openings of the bottles and nipples face downward. This will encourage the functionality of the machines.

These machines are found in different size and shape in the market. The capacity to sanitize a certain amount of bottles vary. Some can sanitize a few at a time and some can do it more.

Microwave Sterilizer

Microwave machine can efficiently sanitize baby bottles in two different ways. Cleaning your microwave regularly is a good habit as it is needed. The job will be done more efficiently if you use a microwave steam sterilizer. The shape also fits baby bottles. You just have to add water to the bottles as it works by the water steam heat. Then place it upright inside the machine. When the sterilization is finished, the microwave makes a sign and you will get sterilized bottles. It takes only a minute and a half to finish the job.

Boiling Method for Baby Bottles Sterilization

Boiling baby bottles need a clean pan with a lid. You should not use this pan for other use like cooking. You have to cover the pan with the lid properly after placing all the bottles and nipples. In case of plastic bottles, you should place it with some weight because plastic bottles float as they are lightweight. You have to make sure that there are no bubbles trapped inside. 5 to minutes boiling is enough to sanitize bottles. As this method can damage nipples and bottles, you should check them frequently. After finishing boiling, carefully set them out and place upside down to dry out.

UV Light Method

This is a newly discovered method for baby bottle sterilization. The ultraviolet light has been used to sanitize and purify water for quite a few years but this is very recently used as baby products. The ultraviolet light can destroy bacteria, virus and mold and this method is using for the sterilization of baby bottles and nipples. The sad news is that this machine can only be used for sterilizing nipples, caps and rings because the size cannot fit bottles. But this machine is lightweight, easily portable. This machine takes only three minutes to sterilize things.

Cold Water Sterilization

When there are no ways available to sterilize your baby bottles, maybe at the time of traveling, you may have to use cold water to sanitize your bottles and caps. Be careful about using the solution and so, use it as the direction says. Make sure that there are no bubbles inside the pan. Use weight to keep submerged bottles and nipples in case of lightweight plastic bottles. You need to be careful about the pan material because some materials like plastic can contaminate the sterilizing solution. Food grade container is useful in this case. Avoiding non-purpose container is good. You can also use a sterilizing tablet. Carrying this is easy.

Duration of Using Sterilizer

For the first year, it is mandatory to use sterilizer and it must be proper. After one year, your baby can develop a strong immune system to tolerate a certain level of germs. But it will be wise to use sterilizer for some more time. Many mothers prefer to use it until bay stop using bottles. It is a good choice too. Because the tolerance level may vary as children may take more time to develop a strong immune system.

Importance of Using Sterilizer

Many mothers feel that the sterilizing bottles sterilizer is unnecessary choice. But we will recommend it to use it. Mothers who use sterilizer should not be convinced with that idea. Just believe your choice. It is always the best idea to use a sterilizer. Your baby’s protection is your concern.

To Find the Right Sterilizer

The worst time comes when you see your baby sick. Mothers sometimes feel very bad that they become exhausted and tired thinking about the illness of their babies.

Size of the Machine

Machine’s size is also an important fact. A mother who breastfeeds may need to use 2 or 3 bottles. In this case, small size is enough. For the mother, who use a lot of bottles, they will need big size. So, before purchase, size should be considered as the need.

Number of Bottles can be Sterilized at a Time

Babies who take their food frequently, need more bottles in very small time. So, mothers may need to sterilize all bottles at once. In this case, machines should be like that. Mothers who are busy with their other works, they may need to sterilize all bottles at once and they may use a lot of bottles. So they will prefer such machines which can sterilize many bottles at a time.

The Expense

The expense is must an important concern. Machines should match parent’s financial capability. Generally, the microwave sterilizer is of low in cost. People who have the low financial capability, they can purchase microwave sterilizer machines.
