This bottle nipple is so nice to have because it can fit on any mason jar. It also fit in our baby mouth so well.

I used these with my littlest and it just made the bottle process so much simpler. They pair with mason jars, which are easily washed in the dishwasher. These are easy to clean with a bottle brush and work well at providing a flow suitable to the baby (because it’s flex, baby does have some control over it). The only downside is that it’s no match for my now 1year old’s teeth. He can rip the hole bigger in seconds. But until those cute pearly whites popped through, these were my favorite nipple ever! (And he’s my sixth, so I have a bit of experience. 😉)

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.

These nipples are awesome and have really simplified the process for me. My daughter as lurangrual malatia (or however you spell it) and I have a heavy let down so I am unable to breast feeding we tried so many bottles but it was all to complicated. I am so happy I found these, i pump and pour right into them. The only reason I gave 4 stars is because they do not have the lab results to say how much the nipple actually produces so my doctor really doesn't approve of our using these nipples. But it's the only ones we've found that she doesn't choke and cough through the whole bottle. (To the manufacturers, we need the data to back up the flow rate. I've recommended these nipples to many people and my doctor has sent the lab paperwork to you. Please follow through :)

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.

Happy to use my small mouth glass jars. Most people have them, so if you forget the bottle they are even extra handy! I always keep the nipples in the diaper bag super handy.

Very short nipple. My breastfed baby did not approve. I ordered 2 Comotomo brand nipples as they fit mason jars as well. Looking to see if they work better as the nipples are longer
