I had never used a bottle warmer until my brother’s wife had twins. I stayed with those sweet boys for a week to help manage their nighttime feedings. When we got up with them in the middle of the night, I loved the efficiency of using a bottle warmer. When I was putting together my baby registry, I knew I wanted one even though it wasn’t an absolute necessity. Little did I know, not all bottle warmers are equally safe or effective.
What are the cool features that make this bottle warmer stand out?
After doing some research, I learned that most bottle warmers use steam to heat breast milk. Steam can overheat breastmilk, which can deplete its nutritional value. (You can read more about a study on this subject in this useful scholarly article about human milk warming temperatures). However, I was able to find a bottle warmer that does not use steam to heat breastmilk. This is why I wanted to write a Kiinde Kozii review.
The Kiinde Kozii breast milk warmer and bottle warmer uses advanced technology to safely heat breastmilk. Instead of using steam, the Kozii warms a small amount of warm water in a reservoir to heat bottles and breastmilk storage bags. It’s a versatile machine that keeps breastmilk safe from damage while making bottle feeding easier. According to the Kiinde website, the Kozi is “specifically designed to follow CDC and USDA guidelines to safely use and thaw breastmilk.” The Kozii is quite a bit more expensive than other bottle warmers on the market, but I think it is worth the extra cost.
Universal Chamber
The Kozii’s universal chamber will heat breastmilk stored in a wide variety of containers. Standard plastic bottles will work, as will my favorite glass bottles. I loved that I could warm breastmilk safely while it was still stored in plastic breastmilk storage bags, whether those bags were frozen or thawed. This made the process of warming expressed milk quite simple. I set the Kozii’s timer for the right amount of time for the container I was using and the state of the milk (frozen, refrigerated, or room temp). The Kiinde Kozii can be used to reheat baby food, even in jars. That’s an especially fun feature for moms who make their own purees. (I thought I would be one of those moms, then found I couldn’t be bothered. Maybe next time around!)
Dynamic Timer
The front of the Kozii features a dynamic timer dial that lets you choose a heating time from 1-15 minutes. For example, a 4 oz. plastic bottle of breastmilk from the refrigerator requires 6 minutes to heat, whereas a 4 oz. glass bottle from the fridge requires 5.5 minutes. An 8 oz jar of baby food from the fridge requires a full 15 minutes. I taped this warming time chart to the inside of the cabinet where we created our bottle station. I referred to it each time I warmed breastmilk for my baby and never just guessed how much time a particular vessel needed.
Automatic Switch Off
When the time you’ve selected runs out, the Kozii automatically turns off. So if you end up leaving the bottle in the reservoir for a few extra minutes beyond the time you set, the bottle will not be heated for those additional minutes. Although the Kiinde Kozii has these great features, you should still always check the temperature of your child’s meal before serving.
The Kozii uses a small amount of water (about 2 cups) in its reservoir and does not require measuring or adding water with each use. I love this feature because I am concerned about water conservation. While I know I could safely heat breastmilk by holding a bottle under a steady stream of warm water, I know that would be a water-intensive practice that I would prefer to avoid.
How It Looks
My Kiinde Kozii review would be incomplete without discussing how this product looks! While it’s not as stunning as say, a Smeg toaster, the Kiinde Kozii is unobtrusive. It takes up a small amount of space on the counter and doesn’t need to be hidden away. The design is simple and utilitarian, with rounded corners and a white body. It doesn’t immediately scream, “A baby has taken over my entire house, including the kitchen.”
This special bottle warmer retails for $69.99. I was thrilled when it was offered for a lower price on Amazon Prime Day this year. You’ll find many other bottle warmers in the $20-$30 range. Just remember that those bottle warmers could possibly compromise the quality of your breastmilk. If you want to save money, simply don’t buy a bottle warmer and go the warm water route.
I loved having a safe bottle warmer because it simplified bottle feeding, particularly at night. I had a great experience using the Kiinde Kozii, and recommend it primarily because of its innovative heating technology that keeps breastmilk at a safe temperature.
