Mason Bottle Glass Baby Bottle DIY Kit – Fits 4oz Mason Jars – Includes 2X Slow Flow Nipples, Silicone Sleeve, and Cap (Ring, Lid, and Jar Not Included) – Made in USA

We use mason jars for everything, so this just made sense. I love that I can pour pumped milk into a mason jar, store in the fridge or freezer, warm it up in a bowl of warm water, and serve it - all in the same jar. Plus, they stack easily and there is no waste. In the freezer, I place my jars in a freezer bag. I bought the 4 oz. and 8 oz. kits. Do yourself a favor and buy both kits. Then make sure you're stocked up on the right jars. I prefer the 8 oz. jars because they are easier to hold and sometimes I pump more than 4 oz. at a time. I breastfeed about half the time and feed with pumped breast milk the other half of the time (so my husband can bond with our little one) and it's so nice to have 4 nipples and a ton of jars and lids. Our baby loves the nipples. She took to it so quickly on the first try. I do use nipple shields when breastfeeding, which is probably why we can go back and forth so easily. I usually use the turquoise holders to measure pumped milk since my wearable breast pump isn't always accurate. We rarely use them when feeding our baby, but that will probably change when she starts holding her own bottles. I wash everything in this kit in the dishwasher. I also wash mason jars in the dishwasher but hand wash the metal lids and rings.

This bottle is incredibly important to me as avoiding plastic with my newborn baby was a top priority! This bottle was easy to use, easy to clean, it fit anywhere & everywhere, and quality was exactly what I was looking for. I wish more people understood how horrible PLASTIC is!!! Hot milk in a plastic bottle I could cry!!! This bottle was a brilliant idea!!!

Was hesitant about this purchase, but I’m so happy with it. Doesn’t leak, fits a small mason jar as it’s supposed to. Easy to clean. My little one mostly bf, but on the occasion that she needs a bottle, this works great

We LOVED these at first with our kiddo. The only down side is there isn't an inbetween flow option for the nipples which our girl needed. The slow become to slow and the next one up was too fast. So at that point we had to switch bottles, but still works great for bringing snacks on the go with a mason lid or storing purees!

My baby takes one bottle a day since about 1 month old - to 6 months now and continuing and this has worked amazingly for him. I love the silicone sleeve! The cap is great! The the bottle top has always worked well for my baby.

I loved this as a product idea and it was not a bad product to use, however the shape of the nipple is not great for breastfeeding babies. The design of the nipple mimics an engorged breast with a tiny nipple poking out and not a real nipple. I didn’t know that as a first time mom and loved these until my lactation consultant informed me it was part of the reason my son was not latching correctly.

When I had received an obviously opened box for this mason bottle kit, I reached out to the company and they shipped a new one out to me within days. Great customer service! The bottle kit comes with a bottle cover, a cap, and two slow-flow nipples. Perfect for our newborn! We love that we are able to collect breast milk and keep in mason jars that we can turn into bottles as needed! It’s minimal and easy! Definitely a must-have, especially if breastfeeding.

I really wanted to love these because I’m committed to using glass bottles for our newborn’s pumped milk. Unfortunately, the nipple leaks every single time I try to use them, resulting in spilled, wasted breast milk—and our baby gets soaked in the process. This is a huge inconvenience and a major disappointment. Additionally, the cap doesn’t even fit on this bottle ring/nipple, so that is useless as well. I’m hoping the seller will make it right by sending a replacement set of lids and nipples at no cost.

Excellent product and arrived ahead of scheduled delivery. Good value for money.
