Silicone Breast Milk Storage Bottles
One bottle. Three jobs. No drop wasted.
Pump into it. Store in it. Feed from it — no transferring, no extra containers, no plastic touching your milk at any step. One bottle replaces three.
Soft, squeezable, and completely plastic-free — these are the world's first 100% silicone 3-in-1 breast milk bottles designed to do it all. Named Parents' Best Breastfeeding Accessory of 2026, and it's easy to see why.
The Three Jobs — Done.
- 🍼 Pump — attaches directly to most leading pump brands (Spectra, Medela, Elvie, Willow, Momcozy, and more). No adapters, no extra parts.
- ❄️ Store — freezer-safe, fridge-safe, and fits inside the MilKeeper® cooler to keep milk cold for up to 20 hours on the go.
- 👶 Feed — attach a nipple and feed directly. Your baby never touches a plastic bottle.

Let customers speak for us
Just received these bottles and the quality is great. They fit perfectly with my spectra flanges and are much lighter than glass options. It's really nice to have a silicone bottle option. Highly recommend!
I love this stylish and fun little cooler. No one can ever guess my liquid gold is inside. They think it’s a water bottle. It keeps my breastmilk cold all day while I’m out and about seeing clients!! ❤️
I've been using these to store milk from my MOTN pumps, and love that the silicone sleeve and cap make it a very quiet option, while keeping things plastic -free. I'm able to write the date in dry erase marker and it stays put until wash time but doesn't stain the glass or label. They're also just really cute little bottles! Would definitely purchase another set!
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!
I had to buy smaller flanges for my spectra and they wouldn’t stay screwed on to the plastic bottles (which I already didn’t like because plastic is nasty)! I love these bottles, they stay screwed on REALLY well, and keep my sacred milk from sitting in plastic. I love that it comes with 3 so I can keep one rotating out in the fridge.
Thank you, Mila's Keeper, for making these silicone breast milk storage bottles. I am a working mom, so when maternity leave ended, I needed to ensure my baby could take a bottle. We spent weeks, including visits with a lactation consultant and a baby physical therapist to finally get our baby to take a bottle, and only Lansinoh would do. Unfortunately, my daycare does not accept glass bottles, so I have been stuck using plastic bottles--worrying constantly about microplastics. Yours is the ONLY product that is silicone; works for pumping, storage, and feeding; and is compatible with a Lansinoh nipple! Which means not only can I rest easy that my baby isn't drinking microplastics, but I can also avoid milk loss from transferring milk from a pumping container to a bottle. Thank you so so much!
these little bottles do it all AND do not contaminate milk with micro plastics. 12/10
This thing is awesome! I really wasn’t sure that’s I’d ever have use for it because my baby girl is always with me. However, when we’re out running errands she tends to sleep longer and my **** can get uncomfortably full. Pumping and then pouring into the silicone containers is such an incredible relief and I know it’ll stay safe and cool in the Keeper until we get back home. If you’re not sure, GET IT.
I have been using MK for a month now, and it is perfect. I purchased everything (bottle/scilicone bottles/extra freezer capsules). Pumping at work was something I was dreading, but MK has made this transition seamless and cute. The wide neck bottles fit my pump perfectly so I have cut down on equipment and cleaning time. I am able to store BM at my desk and not have to use our public staff fridge. Plus, everything is so visually pleasing that I feel cute on top of productive. I 100% recommend all of their products. I am going to order another storage unit so I can store food and additional travel milk for when we have a longer day away from the home for later use. My husband also loves the system and is impressed with the thoughtfulness of this product.
I purchased 4 of these bottles so I can store my pumped milk in them during the day at work. I love these bottles. They’re very spill proof and well made. I also wash them and put them in the bottle sterilizer and they’ve held up perfectly.
I absolutely love using my Milkeeper and glass bottles—it's been a game changer for work! I use a different Milkeeper for each pump session, and the color options make it super easy to keep track of which sessions were in the morning and which were in the afternoon. It takes all the guesswork out of organizing my milk, especially on busy workdays. The glass bottles are sturdy and feel high quality, and the overall system is so convenient. Plus, it's so cute to carry around—it doesn’t even look like typical pump gear, which I love. Customer service was also fantastic—responsive, friendly, and helpful. Highly recommend for any pumping parent!
I’m a pediatric nurse who was looking for an alternative to plastic to pump into/store my milk when I’m in shift. The silicone wide neck bottles fit my spectra perfectly! I can’t wait to order the narrow neck ones for my Medela!
I love the option of a FULL silicone bottle (lid included). No plastic. And they really are leak proof! These are awesome.
Mila's Keeper is wonderfully designed and thoughtfully designed. I'm so happy I discovered it and purchased it as a gift for myself! As a self employed new mother it's the tool I was looking, it gives allows me successfully pump and store my milk when away from my baby. We are striving to be plastic free in our home, having the glass keeper bottles is amazing and the fact that my bottle cap and nipple fits the keeper shows how thoughtful the deisgn really is. It's the gift I think every new mom should be receiving and my new go to for every baby shower I attend!
This has been great for my now 3 month old anytime we leave the house I know my breastmilk is at a safe temp for feeding on the go.
