Overview
Description
The Mila’s Keeper MilKeeper Breast Milk Cooler Set is a pump-to-feed starter kit that lets you pump, chill and feed from a single glass bottle—no transferring milk between containers.
The 3-in-1 glass bottle is available in standard and wide neck sizes, compatible with leading breast pump brands and nipples. Pump directly into it, place it in the included cooler with the ice pack, then feed straight from the same bottle. Used with the bottle, the cooler holds 5 oz; used on its own, it holds up to 12 oz.
The included ice pack keeps milk cold for up to 20 hours. The full set includes the cooler, ice pack and glass bottle with silicone sleeve and lid—everything you need to get started. The bottle is made of medical-grade borosilicate glass with a premium-grade, LFGB-certified silicone sleeve, a higher standard than typical food-grade silicone. It’s BPA-free and lead-free, dishwasher safe and TSA compliant.
Compact enough to drop into a purse or gym bag and sized to fit any cupholder, the MilKeeper is a practical grab-and-go option when you don’t want to haul a full cooler bag.

Saved a bottle for 9 hours in hot car in the middle of the day. Couldn’t believe it withstood that heat on top of day to day transport. Makes everything easier and more tangible when your days revolve around milk!

Beautiful and functional
I have two of the milk coolers and I absolutely love them. Most importantly they work well to keep my milk cold, but I also find that they are beautiful, durable, and sized well to slip into any bag.

I love the size and the design is beautiful. This will be really great for travel and work. I'm a little nervous about the gel ice pack leaking so I've only been using it with the bottle inside. If the cap was more insulated or stainless steel, this would be 100% perfect.

Love it for on the go pumping
This set is super cute and just as functional. I breastfeed baby at home and pump at work where I have access to a refrigerator/freezer, but there are some occasions where I need to pump on the go. Just today I trialed the Mila’s Keeper bottle and cooler during a hair appointment. My little one is still breastfeedinf every 2-4 hours, but my hair appointments (long and dark) take anywhere from 4-8hrs depending on the service.
I opted for a shorter service, which still took about 4 hrs. I…

SO CONVENIENT!
I absolutely love the Milkeeper! I did so much research on breastmilk storage for on the go & almost bought the Willow brand one but lots of reviews said it leaked - I’m so glad I went with this one! No problems leaking and it’s so simple/easy to clean. I also love having the option of storing my breastmilk in a bottle in the container or just straight in the container. Also the fact that it looks so cute is an added bonus!
