How does it do all the things you say it does?

We get it, it can be hard to figure out the first time.Ceres Chill has a small number of parts that recombine to meet all your needs throughout the day — commuting, working, traveling, and having fun out in the world with or without the baby. Any caregiver can take Ceres Chill on an adventure! 

In this little video, Terra shows you how it works.

Can I use a hands-free bra?

Yes! Ceres Chill assembles with all that you need to double pump with a hands-free bra. With each Ceres Chill, you get one lightweight 12-ounce Milk Chamber that connects directly to your pump and another light 3-ounce capacity chamber which doubles as the Cup so you can easily pump both sides without bringing a ton of extra plastic in a cooler with you everywhere you go. 

Here's a diagram of the parts and how they go together

Can I add warm milk to already chilled milk?

Yes! Although there is a lot of conflicting information out there on the internet, recent research is clear: You can absolutely pump directly into chilled breastmilk. It's not only safe, there are additional benefits to doing so. Here's a snippet of the research: 

We found that a single daily [pooling of warm and chilled breastmilk] provides several important benefits— consistent nutrient quality, equivalent bacterial content, and improved maternal satisfaction—over individualized collection.

How does pumping warm milk into a thermos cool it and keep it cold?

Ceres Chill has an amazingly engineered, patent-pending dual chamber system. The outer chamber holds the ice - just a few cubes and a bit of water in contact with the inner Milk Chamber is all you need. You then just pump directly into the 12 ounce inner Milk Chamber as needed throughout the day. Thermodynamic tests show milk being chilled down to 42 degrees within 1-3 hours and staying well within safe storage temps for 20+ hours in 68-72 room temperatures. 

How many ounces does Ceres Chill hold?

12 ounces for 20+ hours! No more messy, sticky blowouts while pumping or trying to switch bottles that are too small mid-pumping. Consulting with pumping mammas and lactation consultants, 12 ounces is the ideal capacity to safely store milk for a normal work day or cross-country flight. Most moms pump 5-10 ounces in a workday so we wanted to make sure we had you covered while keeping the Chiller lean, light and easy to grab, stow in a bag, or tuck in a large cupholder.

Special ways to use Ceres Chill to store up to 34 ounces of milk

Do I need more than one Ceres Chill?

Nope — we've got you covered with just one, even for double pumping! Take one Chiller to work or the airport, pump into it one, two, three or more times through the day, bring it home to the fridge so your baby has milk for all the bottles during the day then...Commute, work, pump, return, feed, repeat. The most convenient way to use Ceres Chill stores up to 12 ounces. 

The User Guide that comes with Ceres Chill shows all the ways to use Ceres Chill to safely store up to 34 ounces of milk. 

How about airport security screening?

We have taken all TSA and government office protocols into consideration with this design. Using an open water chamber and a separate breastmilk reservoir that can be easily and cleanly tested without compromising your milk, Ceres Chill moms will skate through security as smoothly as any of us ever did...which is not to say that TSA is easy, just that Ceres Chill and your breastmilk won't make it harder than it needs to be.
