1 Keeper™ breastmilk holder and organizer
breastmilk holder & organizer
Keeper™ helps you organize your freezer and efficiently store and protect your precious breastmilk by holding storage bags flat, on easy-to-access shelves.
Technically, breastmilk will expand approximately 10% when it freezes. Practically speaking, you will be safe if you leave about 1/2oz of air in the pouch. This does NOT need to be a precise measurement!
The less time your breastmilk spends at room temperature, the better! When pouches are frozen flat, they have an increased surface area (for a given volume of milk), which means faster heat transfer to the milk. This translates to faster freezing, and faster thawing. This faster thawing and warming is of course something you will also appreciate at feeding time!
Twist Pouches™, Direct-Pump™ adapters, Keeper™, Squeeze™ natural feeding bottle, and Active Latch nipples™ are made of polyethylene (LDPE and HDPE), polypropylene, and silicone. All Twist™ products are BPA-free, PVC-free, and pthalate-free.
Studies show that exposure of breastmilk to temperatures higher than 60C can destroy the important antibodies and can denature the proteins contained in breastmilk. The temperature of steam is 100C or hotter. Microwaves can cause local hot spots within the breastmilk, meaning that, even if the overall temperature (the "bulk temperature") of the milk feels safe, small pockets within the volume may have been temporarily heated well above 60C.
