Say goodbye to the 1950's breastmilk storage options! Clunky coolers, bulky bags, batteries and cords are SO yesterday. Ceres Chill keeps breastmilk or formula safe for up to 16-20 hours with just a handful of ice!

And now you can enjoy the convenience of one full-sized 27 ounce Breastmilk Chiller and one 12 ounce Demigoddess Mini Chiller! Having two Chillers frees you up - never worry about those extra few ounces at the end of the day that don't fit in your OG Chiller. Never stress about having an epic, compact way to store a few ounces of milk while you're out of the house. We got you! 

Pump directly into either chiller and enjoy up to 20 hours of safe chilling. Compatible with all major breast pumps, and you can even use the lid for double-pumping or feeding your baby with a standard nipple assembly! 

  • Up to 20 hours of safe chilling with the OG Breastmilk Chiller
  • Up to 16 hours of safe chilling with the Demigoddess Mini Chiller
  • Extra-large capacity: Holds 6oz – 16oz in the Demi, and 12oz-34oz in the OG
  • Chill and store up to 12 ounces in the Demigoddess and 27 ounces in the OG Chiller.
  • Compatible with all major breast pumps
  • To see if your pump needs an adapter, check out our FAQ page. 
  • Easy to use and transport
  • Reduces risk of contamination
  • Travel friendly: TSA loves it!
  • FSA, HSA, and HRA reimbursable! Use your card or reimburse through your provider.
  • All parts are interchangeable: Use your Demigoddess Inner Chamber with your OG Chiller for more capacity! See our tutorial here. (link to tutorial)
  • Comes with a Lifetime Warranty

Awesome perk of the duo: Use your OG Chiller or Demi Mini Chiller as a bottle warmer!

  • Just add hot tap water to the outer chamber, and add up to 12 ounces of milk into the OG Chiller Inner Chamber, or up to 6 ounces of milk in the Demigoddess Inner Chamber. 
  • Store the nipple safely and cleanly in the upper cup.
  • When you're ready to feed your baby the chilled milk, remove the nipple from the cup and connector.
  • Wait about 7-10 minutes and you'll have a perfectly warmed bottle!
  • One Chiller filled with hot water can warm up to three bottles over 8 hours. Need more warm bottles? Just add hot water to the outer chamber and go!
  • Read the complete product guides for how-to instructions.

One Chiller to chill your milk and one to warm it makes for a happy baby—road trips, long walks, and life itself just became waaay easier!

Work great for pumping at work!


I was really looking forward to using this product as I will be going back to work. I looked up alot of reviews and videos before I purchased it but after trying it out for about a week, I realized that the ice melts quick, at first I thought maybe I added to much water but no. The max about of time I give the ice is less than 3 hours.

Jackie! Oh wow! Please know it can be completely normal for your ice to melt a bit after several hours! Remember, the chiller is designed to hold breast milk, that comes out of your body at 98.6*F, and bring the milk down to a temperature that is safe to store milk! (59*F according to the Academy of Breastfeeding Medicine). Even if your ice has melted a bit, it is still working to chill and maintain the temperature of your milk for the rest of the 20 hours! In case it helps, here’s our blog post about this:
I definitely want to make sure that you feel comfortable and confident using your chiller, though - I just sent you an email, please reach out to me anytime to talk this through. I'd love to make this work for you if I can.

All my best,

Ashley M.
Amazing product!!

As a two time exclusive pumper, this is the best product I have purchased on my breastfeeding journey!


As a healthcare worker with little to no time to pump and keep my milk cold. This has been a live saver! Thank You!


I love this chiller so much, I’ve told all my friends about it! Even more I’ve loved the education to go with it. The help of understanding how to travel with it and how to use is so helpful, this company definitely understands the needs a of a mom and has answered the questions in advance!
