Mason Bottle Fast Flow Nipples (6+ Months) – Silicone Baby Bottle Nipples, Fits Any Regular-Mouth Mason Jars – Wide Natural Shape, BPA-Free, Non-Toxic, Made in USA (2-Pack)

I was recommended these Mason bottles from a friend and I absolutely love them! I started with the slow flow while I was breast-feeding and bottle feeding, but now that my nine month old baby is drinking only formula, we use the fast flow nipple. There is little leakage when you turn the bottle upside down. The quality is very high because the nipple is malleable and stretchable like a human nipple, but also durable. I love how easy these are to clean in comparison to other baby bottles because I just put them in the dishwasher with the sanitize mode selected. No need to buy extra bottle sanitizer machines that clog up the counter! It saves money and it saves you counter space! I would only recommend these Mason bottle nipples for baby bottles!

My daughter transitioned easily from Philips Avent bottles to these. They make glass bottles much more affordable, especially if you already have plenty of mason jars. No issues with leaking either.

I love this product! I found it by accident and so glad I did. Works great for baby that formula feed or breast feed. When I was breastfeeding I would pump and put my milk in small 3 0z jars or the larger jars, place lid on and put in the fridge or freezer for storage avoiding the extra step of the milk storage bags and saving money by doing so. When a bottle is needed out of the freezer or fridge simply place glass masor job in a small bowl or warm to hot water and it's ready in a couple minutes. Pop one of these great nipples on and your ready to go. When we switched to formula since the jars are reasonably priced and I had a large amount from using to store breast milk I than started to prefill bottles (jars) with dry formula mix for the week saving time and keeping the formula fresh since formula was than in nicely sealed jars vs in formula bag and it being opened and exposed to moisture in the air several times a day had I made individual bottles as I went during the day. Huge time saver doing it this way! Pop a nipple on and add water and ready to go. Only downside with using the mason jar parts with nipple is once discarded into sink after bottle is used be sure metal parts of jar are not sitting in water for too long as they'll rust a bit on seem. Barely noticeable but something to be aware of. I hand wash to avoid but if the small amount of rust doesn't bother you (exterior parts, does not affect interior of bottle, completely safe for baby) than metal parts can be placed in top rack of dishwasher. I recommended these nipples to all expecting and new mom's I meet and often give as a baby shower gift. My LO is 6 months old and this is all we have used since 3 days old. She breast feed and bottle feed from day 3...in large part I think because of the shape of this nipple being similar to that of a real nipple.

These are fantastic. They are easy to clean and the milk flow is simple without being to much or to little. It's easy to use and fits on any regular mason jar. It's a sturdy product. It could be made with a slight bit softer material, my baby does get air through the sides of mouth on the occasion. Would buy again though.

We like being able to use glass bottles. Over all we loved these other than the seal will not always work and you will have leaks. That was a huge downside but not enough to revert to plastic bottles. The quality of the nipples are well made and don’t puncture easily with little front teeth. Easy to clean with a brush and the design shape was much better for the baby getting a good suck going.

Works great with our mason jar bottles. Slow flow for my breastfed baby! We

Really love the fit and nipple design.

I could not produce enough breastmilk, so we had to supplement with formula since my baby was a few days old. We used a syringe and finger feeding for her formula for the first few weeks. I wanted to continue breastfeeding as much as possible, but my lactation consultant said if we used a bottle for her formula she might not nurse from the breast anymore. I chose these bottle nipples because they are silicone and we can feed her from a glass container instead of plastic, but most importantly in my baby's case, they are very similar to a natural nipple/breast shape. I have been using these bottles to feed her for 10 days now, starting when she was 3 weeks old, and she is able to switch back and forth fine between breastfeeding and her bottle. I am relieved and grateful I can continue breastfeeding her as much as possible without her rejecting it. One thing I will say is she does spit up more from using the bottles. It may just be because she is so little. We just have to be careful to burp her often. I am pleased that they are easy to clean and very high quality. They do not leak for us at all. It is easiest to press the nipple into the metal ring for the jar first before putting it on the jar and then attempting to screw the ring on last, since the base of the nipple fits snugly into the ring. It makes a very secure seal and the air vents work well without leaking.
