LOVE this chiller. Can't give it enough stars. It was amazing while traveling and pumping and not worrying about the milk staying cold. Lifesaver!!!

Milk isn’t staying cold

A friend recommended this product and I wanted to love it. I bought a combo large tumbler and small tumbler. Both of the chillers are not keeping my milk cold. I read the instructions multiple times to ensure it was not user error, it was not. I used my large chiller today and after 10 hours of the milk being stored I checked the temperature it was 66 degrees F. Basically room temperature, needless to say I had to throw away almost 12 ounces of breast milk which was devastating. I will be searching for other storage products and unfortunately not be recommending it to other moms.

Hey Nicole!
Thanks so much for reaching out, we would love to help you out with this. Did you happen to add pumped milk to the chiller 2-3 hours before you checked the temperature of your milk? It can take up to 4 hours from your last pump session to bring your milk down to a safe temperature for storage. If you had pumped a few hours prior to getting home, it still brought your milk temperature down almost 40* in just a few hours and that is remarkable! 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). It’s also likely that if you gave it another hour or so, it would be at 59*F and possibly even below that in no time at all! Whether your milk is placed in a chiller, cooler, or fridge it takes time to bring it down to a safe temperature.
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 - please reach out to me anytime to talk this through. I'd love to make this work for you if I can.


Works so well to keep breastmilk cold! Brought it along while pumping at a wedding and a concert. Easy to stick in a cooler.

Best thing ever to be invented!

Prior to purchasing the Ceres Chiller, I thought I could just use any tumblr and it would be fine but it was not as simple as I wanted it to be. But the Ceres Chiller just works. It keeps my milk cool during work, travel, and any dreamily outing we decide to pursue that day. I love it.


I was able to take my manual pump and attach it directly to the chamber. It was such a seamless process and allowed me to easily pump on a boat in the heat of summer and keep my milk cool! I plan on bringing the chiller to a 3.5 hour concert this fall and I’m so grateful to not have to worry about the safety of my milk.
