Tommee Tippee Closer to Nature Insulated Bottle Bag - Pack of 2

Best Baby Thermos

My pick of the lot is from the brand Tommee Tippee. They are known for their baby products and I have listed several for you in the last few months. This particular thermos is designed to carry baby milk bottles and maintain the optimum temperature requirement.

Babies are fussy when it comes to milk and they need it at the right temperature. I came across the Tommee Tippee Closer to Nature Insulated Bottle Bag while browsing on Amazon and I liked the offer and the pricing. 

It comes in a pack of two and is designed to warm liquids warm and cold liquids cool. It is a flexible thermos that will work in any weather condition. With this two-pack thermos, you can get the best of both worlds and mix and match to get the right temperature for your baby.

Thermos 183270 Stainless King Food Flask - 470ml

Best Baby Thermos

Thermos is the boss of baby thermos brands in the market. They are known for being versatile and for being best sellers in this segment. The product has a wide mouth that helps in pouring and storing milk easier with the right kind of container. 

After using this thermos, I can vouch for their claims of keeping food hot or cold for approximately 9 to 14 hours depending on the type of foodstuff. Another feature I like most about this thermos is that the outer layer doesn’t become too hot making your palms sweat or doesn’t freeze your hands when you keep something cold. It stays neutral and that shows the build quality.

Why do you need this?

  • The Thermos Stainless King Food Flask is childproof and spill-proof so you can be stress-free.
  • It is available in a lot of color choices to match your style.
  • It is a genuine product designed to maintain the food temperature for long hours. Vacuum insulation makes this possible.
  • It has a durable stainless steel interior and exterior
  • It includes a full-size folding spoon and insulated lip that doubles up as a bow.
  • It comes with a 5-year guarantee

The price may be a hindrance when you compare it with other brands

Lekebaby Double Baby Bottle Cold Bag - 18oz

If you are a new mom and are still breastfeeding your baby and you intend to keep the expressed milk at the prescribed temperature, this is the right product for you. Lekebaby double baby thermos cold bag can hold two big bottles of milk nice and cold close to 8 hours. It is your perfect partner if you are out with your child and are traveling for long hours.

I can vouch for this as the temperature was nice and cool just like I had stored it when I first used it. I have also stored formula milk and it stayed at the same temperature. So that’s a bonus. It is not just for breast milk but for other liquids too.

Why do you need this?

  • The technology is simple, the bag itself is insulated and has an ice pack that keeps the contents cool.
  • As it keeps the milk cool and prevents it from spoiling, you can use it to either reheat it later or feed at the optimum temperature.

It is available in many colors and is made from stainless steel that can hold up to 450ml. It has the capability of keeping both hot and cold food. Hot food can be kept hot for 9 hours and cold food can be kept cold for almost 16 hours. Aren’t you impressed?

Another bestseller on Amazon, the WayEee Food Flask is made for keeping hot and cold food for more than six to eight hours. It is made from a double insulated stainless steel that includes double lips keeping the food insulated from the outside temperature.

I like the folding meal spoon that is thrown in completely free. It is made from food-grade material and can be used for soups as well as solid food.

Why you need this?

  • The  WayEee Food Flask has a release air button that helps release gas pressure which may build when food is stored for a few hours due to temperature change. You need not force it open in such situations and can just push the button to open the thermos with ease.
  • The thermos is leak-proof and the 450ml capacity is mighty impressive. The seamless design can hold soups and solid food without any spillage.

Best Baby Thermos - Buying Guide

When I started researching I knew I have to consider the below-mentioned factors as I always want the best for all new parents and their babies. Here are a couple of things our team at TheMiniBlog took into consideration while curating this list of the best baby thermos.

  • Material - The first thing you will need to consider is buying a baby thermos that is made from premium-quality food-grade stainless steel. Since stainless steel is corrosion-resistant and non-toxic, your baby's food will remain safe and wouldn't get adulterated. Choose a double-walled container since that creates a vacuum and prevents heat from escaping.
  • Avoid Chemicals - When picking the right thermos to store your baby's food, make sure it does not contain any harmful chemicals and is BPA and Phthalate free. Always go through the product description and if something you like contains chemicals, stay away from them.
  • Lid with Pressure - Picking a good thermos with a lid and pressure relief system will keep the food hot for longer periods of time by trapping the heat within. This also prevents the food from leaking or spilling if the thermos falls down or is left flat on any surface.
  • Warranty - Finally, make sure that the product you're interested in comes with a valid warranty. In case you receive a defected product or if your product gets damaged, you can claim the warranty and chances are that you can even get a replacement.
