Description

One of the first things your doctor will mention is that you can’t microwave milk to give to your baby because it can get hot spots that will scald your baby’s mouth. (Yikes!) So how do you warm up milk? Some parents just put a bottle in a bowl of warm water and wait for it to warm, but some find a bottle warmer that also uses warm water to be really useful. With a bottle warmer, the process is straightforward and you know the milk is at the right temp.

The Kiinde is a versatile warmer that’s compatible with nearly everything you’d want to use it with - breastmilk storage bags, baby food jars or pouches, and any type of bottle. It is much wider than most bottle warmers, so it can even fit hefty Comotomo bottles. It warms any meal to a comfortable temp via a water bath that’s about the same temperature as warm tap water. That keeps the food from losing nutrients and avoids hot spots.

It also offers conveniences like a large water reservoir you don’t have to refill each time and an auto shutoff function that keeps food from overheating. These are especially handy for parents who are trying to do a bazillion things at once – and if you have twins and need to heat up many bottles one after the other.

Cleaning this bottle warmer though is intense with different steps to be done after a couple of days, weeks, and months.

What we  about it

Heat up any bag, bottle, or jar in this food warmer that preserves nutrients through a gentle warming process.

Simple and effective
This bottle warmer works on both bottles as well as frozen breast milk bags. It’s a simple one piece design so nothing complicated to use or clean, and it works quickly and cleanly.

Night-time ease
This has made night-time feedings so much easier! It fits on my nightstand so we don't have to go up and down the stairs in the night.I just wish it held more water to cover the bags better, but it doesn't impact its function.

Never worked
It has never worked. The bottle has still very very cold after setting the timer for the longest setting. Bought when I first found out I was pregnant and couldn’t return.

Great product and great initial warranty if the heating gets dicey, they will send you a new one if there is a defect with minimal questions asked (you just ship the old faulty one back). Highly recommend!
