Why Should You Use A Baby Bottle Sterilizer?

No matter how careful you are in keeping your baby away from nasty critters, or how clean you maintain your home is, you will soon realize that there is not much you can do against bacteria and germs. For as long as your baby uses bottles, you will need to use a sterilizer to clean these bottles efficiently. Because the immune systems of babies are still developing, they are susceptible to illnesses and infections.

Milk is an easy breeding ground for bad bacteria and cleaning with detergent soap may not be enough. This is the reason why mothers back in the days had to boil a pot of hot water and submerge the bottles, silicone nipples and pacifiers for sterilization. Luckily, technological advancement has helped in the development of the best baby bottle sterilizer that fits the budget.

What Can Happen if Bottles Are Not Sterilized?

Babies are vulnerable to germs that may cause vomiting and diarrhea. These germs can easily develop in milk, making infants exposed to diseases. Teats and bottles have crannies and nooks that may allow milk to build up. The best way to make sure that your little one’s bottles are free from harmful bacteria is by using one of the best baby bottle sterilizers.

How Long Should You Use A Sterilizer?

It is recommended by experts to continue sterilizing your baby’s bottles until he is at least one year old. It is also ideal to sterilize feeding scoops that come with formula milk alongside the baby bottles. Once your baby reaches six months old and has started eating solids, you may try to encourage him to use a beaker or cup for his milk. These are easier to clean and do not have to be sterilized.

Beakers and cups are also better for your little one’s teeth than bottles. You can just wash these in clean, soapy, hot water, along with your baby’s spoon, plates, and bowls. If you want to use a dishwasher, make sure that your baby’s items are dishwasher safe and place them above the rest. Dry your baby’s things with a clean towel. Compared with milk, bacteria do not easily develop in solid food.

Types Of Bottle Sterilizer

Types Of Bottle Sterilizer

There are several types of bottle sterilizer.

1. Electric Bottle Sterilizer

This type of sterilizer, like Philips AVENT 3-in-1 Sterilizer, uses steam to get rid of bacterial and germs that may be present in your baby’s bottles. Some sterilizers also deodorize bottles and they are able to accommodate more than one bottle at once. The process of sterilization is fast, usually less than 10 minutes. However, they are more expensive and may take up more space on the counter-top.

2. Microwave Bottle Sterilizer 

Like electric sterilizers, microwave sterilizers also use hot steam to purge harmful bacteria and germs. To use this type, you will need to place the bottles in the container, add enough water, and put it in the microwave. Like Munchkin Steam Guard Microwave Sterilizer, they are quick, usually less than 5 minutes. They are also very affordable and can be stored in cabinet when not in use. However, there are no deodorizing and drying features.

3. UV Bottle Sterilizer  

These sterilizers are the newest and they use ultraviolet light to get rid of germs and bacteria. These items are the most portable as they are lightweight and small, making it ideal for traveling. However, this may require you to disassemble the bottle and sterilize every piece independently.

What To Look For In A Baby Bottle Sterilizer?

Looking for the best baby bottle sterilizer may be difficult as you would encounter hundreds or thousands of them in the market. To help you choose the right item for cleaning your baby’s items, here are some factors that you may want to consider.

1. Capacity: You would want the sterilizer to be big enough to accommodate your baby’s bottles and other bits. Buying a bigger sterilizer like Dr. Brown’s Microwave Steam Sterilizer can clean many bottles at once, cutting down your workload.

2. Ease of use: The item should be simple to operate as being a parent requires you to do multiple tasks at once. Electric sterilizers are often easy to use, but if there are so many buttons or the instructions are a bit confusing, consider moving on in your search.

3. Drying feature: While microwave sterilizers work fast, the bottles are left wet. Parents will have to dry them after they are removed from the microwave, which adds another step to your job. Some sterilizers like Little Matisse Sterilizer come with a drying feature. Consider this when selecting the best baby bottle sterilizer.

4. Portability: If you often travel, you would want a sterilizer that is both affordable, smaller in size and light for easy portability.

5. Kitchen space: Some parents might want sterilizers that do not require too much space on their kitchen counters. If your kitchen is spacious, this may not be a problem for you.
