Ceres Chill Breast Milk Chillers

For nursing parents who pump away from home, keeping expressed milk safely cold used to mean juggling ice packs, coolers, and a lot of guesswork. Ceres Chill replaces all of that with a single insulated stainless steel container that stores and chills breast milk in one step — pump directly into it, add cold water or ice to the inner chamber, and your milk stays at a safe temperature for up to 20+ hours. It fits most major pump flanges, tucks into a bag or purse, and doubles as the vessel you feed or transfer from later.

The OG Breast Milk Chiller holds 27 oz. and is the workhorse of the lineup — enough capacity for a full day of pumping sessions, available in 0 Dark 30 Midnight Black and Don't Call Me Hon Plum. If you pump smaller volumes or want something that slips easily into a diaper bag, the Demigoddess Mini Chiller offers 16 oz. of the same double-walled protection in Rose Gold, Starry Night Shimmering Black, and Sweet Pea Green. For parents building a frozen stash, the Milkstache Luxe freezing container lets you freeze, store, and thaw in stainless steel with a silicone base — no single-use bags to buy or toss.

A common question: does the milk actually touch ice? No. Milk sits in the outer chamber while your coolant (ice or cold water) goes in the sealed inner chamber, so nothing dilutes or contaminates what you've pumped. Everything is BPA-free stainless steel, dishwasher-friendly, and built to survive years of daily use — a meaningful difference from disposable storage systems. Because these containers are leak-resistant and insulated, they travel well for work shifts, flights, and long commutes.
