Let customers speak for us
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 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.
If you dont have this Breastmilk storage yet, you have to get one! I love mine very much. Its leak proof and very versatile.
Using these silicone bottles for pumping has made my pumping journey so much easier AND better. No more leaks, less parts to clean, and less worries about microplastics! These were exactly what I was looking for, so now I have 12!
Bought this as my current coolers are too bulky and I need something that’s easy on my shoulders and back for short trips: looks amazing
First of all, the set is beautiful and well crafted! Second, it definitely does what it claims. It will keep liquids cold for a long time! I am excited to use this as I go back to work and continue my pumping journey!
So far, we love our glass bottles and wish we had ordered 12 instead of 6, but maybe soon we will. They’re easier to carry than the bags and I don’t have to worry about a proper seal and things being leached into the milk. I suffered from postpartum anxiety and OCD and these bottles have given me peace at mind. They’re super easy to dump your milk into and I use a chalk marker to mark the date and time on the top. The only issue is we have to use the Phillips Avent **** top with our Evenflow nipples because a batch from Target or Walmart has the improper threads. They are a bit heavy to use with the pump, so I just dump into the glass bottles.
i did all the research !! many late nights/mornings pumping and trying to figure out which travel solution would be best to store my precious milk. Firstly I recommend calculating really how many OZ you'll need to travel with to understand which option will be best for you but ultimately for me having an extra bottle on ice and potentially two was what I need for travel days. I just came back from my first trip and this was a breeze going through TSA. the security guy even complimented the Milas and said he has a new baby and wants to get it for his wife!! as long as this can store enough for you i highly recommend! :) my only feedback would be, the silicon top has not shown and leakage whatsoever but does make me nervous that there is not real threading lock system? you can kinda just pop it down but if its patented and works then okay!
This is an amazing must buy product. Keeps everything cold and it feels secure in a diaper bag. I am never worried about anything spilling out. With twins the duo was a must! Can’t say enough good things about this product.
