The Kozii is Kiinde’s breast milk warmer, but it’s also suitable to gently thaw & warm any meal for your baby or toddler.

The Kiinde Kozii milk warmer is the only milk & food warmer that uses a medium temperature water bath to warm your baby’s milk & food.

Price: $99.95

Availability:  Kiinde stockists

We love …

  • warms any bottle or breastmilk storage bags, formula or baby food
  • simple timer is easy to use (especially at night)
  • warm (not hot) water bath maintain nutrients in milk & food
  • keeps milk or food warm for an hour or more

In use …

The Kiinde Kozii is ready to use straight out of the box.  We filled the reservoir in the bottom (2 cups of water) and the Kozii was ready to warm the variety of home and commercially prepared bottled and pouched milk & baby food we had ready to go.

The Kiinde Kozii operates using a timer system, so we popped our milk and food in & set the timer.  The Kozii fills with warm water to gently heat the milk & food.  When the time is up, the water drains and the bag or bottle dries, ready for dinner time.

Being the scientific super-minds that we are (my toddler tester & I), we compared the Kozii to a boiled water & bowl bath.  We found, on average, the Kozii took no more than 30 seconds extra to warm the milk or food and it was easier to use because we had to roll our bottles or food pouches around in the bowl and shake them to get them evenly warm.

Plus, the Kiinde Kozii uses warm water, not boiling water, so you get an even temperature throughout your milk & food and it won’t overheat. Warm water doesn’t break down plastics like boiling water, high temperature steam and microwaves do.

You can clean the Kiinde Kozii with a damp cloth & you’ll need to refill the reservoir about once every 5 uses. The Kozii is also a compact unit, it doesn’t take up much bench space and it’s easy to store.

Finally, during our testing, we found an unexpected advantage.  When left in the Kozii warmer (after the water bath has finished), your baby’s feed will stay warm for at least an hour.  Really helpful if you want to prepare a feed in advance or your baby is a finicky eater.

Consider this …

Various different feeds … breastmilk/food … fresh/refrigerated/frozen … glass bottle/plastic bottle/pouch, take different times to warm.  You may need to experiment with your Kozii to find the right time to warm your baby’s feed.  On average, though, a frozen pouch of breast milk (150mls) will take 8 minutes to thaw & warm.

Food pouches tend to stand out of the top of the Kiinde Kozii warmer.  You might have to turn them over in the unit if they are frozen (you won’t have this problem with frozen milk).

Always check the temperature of your baby’s milk or food before feeding.

The verdict …

The Kiinde Kozii breast milk & food warmer is super easy to use and convenient.   You can’t overheat your breastmilk or baby’s feed and the Kozii will maintain the food temperature for over an hour.

    I’ve only ever heard beautiful things about this little gem, and I can’t wait to try it!

  2. December 25, 2014 @ 12:46 pm Lana Stratigos

    I love that it maintains the nutrients in the milk after it has been heated up, I would hate that my baby can’t get what he needs out of the milk he deserves.

  3. December 23, 2014 @ 10:10 pm Diem G.

    Love how the warmer uses warm water to warm the milk and it looks like it will be easy to clean!

  4. December 23, 2014 @ 2:10 pm laura powers

    Great product would be great to have this around when baby number 2 arrived next year

  5. December 23, 2014 @ 12:35 am Karly

    I like that it takes away the guess work in relation to how warm the milk should be.

  6. December 22, 2014 @ 11:58 am Lauren

    I have been waiting for this product to arrive and can’t wait to get it to add to my Kiinde starter kit to complete my full Kiinde set!

  7. December 22, 2014 @ 10:24 am Kasey Potter

    i think its genius and i cant wait to try it :)

  8. December 22, 2014 @ 9:37 am Cora

    I have waited so long for this to come to Australia!!! i have the whole system but not this and would love to add this, i don’t know how many emails I’ve sent in regards to getting this in stock lol!!

  9. December 21, 2014 @ 8:59 pm Amber

    i have waited so long for this to come out I can’t wait to be able to use it :)

  10. December 21, 2014 @ 3:53 pm Jessica Blundell

    I love the look of it! It looks so organised and simple!

  11. December 20, 2014 @ 12:58 pm Mary tan

    This Would make my life easy.

  12. December 20, 2014 @ 12:54 pm Michelle Harrison

    I think the Kiinde are a marvellous invention and save a lot of time with heating stored milk

  13. December 20, 2014 @ 3:46 am Rachel K

    This product sounds fantastic. It’s great that the warmer shuts off automatically to keep from overheating the bottle. I also love the fact that asides from the bottle the Kiinde warmer can also handle storage bags, food jars, and more.

    helping Nature beautifully!

  15. December 19, 2014 @ 3:48 pm Peta Bruce

    I love the look of it, I’m already buying the starter pack before bub is born in February :)

  16. December 19, 2014 @ 2:20 pm trish

    Looks great!

  17. December 19, 2014 @ 1:11 pm Ebony W

    Starting solids with my gorgeous boy in 2 months time this would be amazing to warm bottles and his food :)

  18. December 19, 2014 @ 12:59 pm

    I think this is a great idea, and can be used for many other heating items after the breast milk is finished.

  19. December 19, 2014 @ 11:40 am Sarah Blockley

    This looks amazing! Warming milk in the microwave is always tricky and if you heat it too much you have a screaming baby waiting very impatiently for the milk to cool a bit, and I love that it can also keep the milk warm for an hour so that I can be prepared!

  20. December 19, 2014 @ 11:25 am Mary Preston

    Convenient that’s for sure. It’s a space saving & time saving system.

  21. December 19, 2014 @ 10:43 am suzie sims

    Safe Fast Easy Universal, need i say more, perfect innovative and every mum should have one!

  22. December 19, 2014 @ 9:50 am Jon

    Picked up the starter kit for baby due in a week, just need the kozii. Looks amazing

  23. December 19, 2014 @ 9:30 am Lauren

    What a fantastic product! A first in it’s class :)

  24. December 19, 2014 @ 9:25 am Annaliese Webb

    I was given the storage starter pack by a friend upon the arrival of my first born. It has been so convenient with simple transfer of the packaged milk stored in the fridge/freezer to bub’s bottle with no milk wasted! The milk and food warmer would the ULTIMATE addition to our household!

  25. December 19, 2014 @ 9:02 am Kristy

    This would have saved me many hours with my daughter, I now have a 7 week old son this is a amazing idea and concept

  26. December 18, 2014 @ 5:43 pm Sarah

    I dont know much about this, but what i’ve seen it would be great to have to try!!

  27. December 18, 2014 @ 5:19 pm Paige Yang

    With Kiinde Kozii I won’t overheat my breast milk, such a fabulous warmer.

  28. December 18, 2014 @ 4:16 pm Jessie

    Have been waiting for months for the milk warmer to be available in Australia, so excited it is finally available

  29. December 18, 2014 @ 3:11 pm karina l

    Best invention ever. You can pump straight into the bags, freeze them (with little space used in your freezer), take it out, reheat, feed and dispose. Easy! Saves on washing too!

  30. December 18, 2014 @ 12:47 pm Tamara Robinson

    Awesome time saver! Can store and heat all in one bag/bottle. So convenient and less mess! I absolutely adore this idea and would be amazing to win such a generous prize!

    I love this food warmer. I can use storage bag of milk to heat up. It is quick and easy for busy mum.

  34. December 17, 2014 @ 11:34 pm Karen Kemp

    What a fantastic system, I wish this was around for my first children.

  35. December 17, 2014 @ 11:15 pm Adele Smith

    A brilliant time saver, a storage system that has taken the mess and complications out of breast milk storage and simplified it, taking care of mother and baby. Truly something special.
