Lansinoh NaturalWave Baby Bottle Nipples, Medium Flow, Size M, 3+ Months, 4 Count – 100% Soft, Durable Silicone, Made Without BPA BPS, Anti-Colic, Supports Baby’s Developing Mouth and Teeth

Worked as advertised.

These nipples fit perfectly with our Gulicola bottles — no leaks, no weird gaps, just a nice snug fit. The flow is smooth and consistent, and my baby took to them right away with no issues switching from breastfeeding. They’re easy to clean and hold up well after multiple washes and sterilizing. Really happy with this purchase — it’s great to find something that works perfectly without any hassle!

If you are a parent struggling with "bottle refusal," you know exactly how stressful the transition to daycare can be. My second child was significantly pickier than my first; she preferred being breastfed almost exclusively, and I was genuinely worried about how she would handle the switch. After trying several brands, these Lansinoh NaturalWave nipples were the clear winner. Why the Shape Matters I originally looked into these because I’ve heard many lactation consultants recommend this specific "sloped" or triangle-shaped nipple. It encourages a more natural latch that mimics breastfeeding, which I think was the key to our success. Before these, we tried the Spectra brand nipples that came with my pump, but found them to be way too stiff. The Lansinoh silicone is noticeably softer and more flexible, giving it a "give" that feels much more natural for a baby used to nursing. Accurate Sizing & Flow Transition The sizing has been incredibly consistent. We recently moved up to the Size 3 (Fast Flow), and the predictability was spot on. My baby could definitely tell the difference—she was getting frustrated with the Size 2, but the transition to the Size 3 was seamless. I love that I don't have to buy entirely new bottles every time she grows; the bottles themselves are so durable that I just buy these replacement tops as needed, which is much more cost-effective. Durability & Cleaning I have been sterilizing these for months now, and they have held up beautifully. Even with daily high-heat sterilization and constant use, the material hasn't become cloudy or warped. They look and feel exactly the same as the day I bought them. Final Verdict If you have a baby who is picky about textures or has struggled with the stiffer nipples that come with standard pumps, I highly recommend these. They made our daycare transition so much smoother and took a huge weight off my shoulders!

😍 These nipples by far are amazing! 😍 A lactation nurse said, that the bottle is not the problem. It’s the nipple!! The nipple should pass the triangle test. 😍 These nipples pass the triangle test and although i DO NOT use plastic bottles, I use these nipples on a glass bottle from another company. 🤦‍♀️ 😮😬 😍 Hands down, the BEST decision/combo I’ve ever made in regards to bottles and nipples!!!! I have tried so many different bottles, and nipple combinations. Once I figured it out, I purchased these nipples in different sizes, and I purchased so many! 😍 By size I mean the flow of the nipple. My son is currently two months and he uses size 2. 😍 Ever since I started using these nipples, the issue with colic has been so much better!! We started on these nipples a while back. I want to say by the time he was 3 weeks. 😍 the GLASS bottle I use is Avent by the way! And I used both the small glass bottles and now the large with these nipples as they fit! 😍 you just have to make sure to close it right as it can leak if you aren’t mindful. But this rarely happens. (There’s a way to close it) 😍 babies having gas is inevitable. Their system isn’t perfect. Remember that. But I know it’s hard! HANG IN THERE MOMMAS AND DADS! By 2 months for sure issues with gas begin to get better as they move around(especially their head) I use European formula and the one I use specifically (Holle-Goat) is rated best but can cause gas on babies. 😍 So when I say these nipples changed the game, they changed the game!

These fixed my baby’s latch issues!! Do try!! My lactation consultant approved

These nipples are great for my breastfed baby. I’ve only used these since she was born and she has not had any nipple confusion switching between the breast and bottle.

Only bottle nipple my son wi take.

I really like these bottle nipples and they are the perfect triangle shape to encourage a good wide and deep latch. The only issue I have is they don’t last long and have to be replaced often. Which I don’t mind.

J’ai acheté ces tétines parce que mon bébé n’avait pas une succion assez puissante pour les tétines Philips Avent. Depuis que nous utilisons les Lansinoh, plus aucun problème : la prise est naturelle et l’écoulement lui convient beaucoup mieux. Gros point positif : elles n’ont pas causé de confusion sein/biberon. Mon bébé prend aussi le sein et la transition se fait sans difficulté, ce qui était très important pour nous. Petit point négatif (mais mineur) : lorsqu’on les utilise avec des biberons Avent, il faut bien s’assurer que la tétine est correctement positionnée au moment de visser l’anneau, sinon il peut y avoir de légères fuites. Une fois bien installée, aucun souci. Globalement, je les recommande fortement pour les bébés avec une succion plus faible ou pour ceux qui alternent sein et biberon.

Lansinoh is hands down the best nipples for babies. The transition from bottle to breast makes it so much easier. They do fit into a lot of other bottles. They were the first to create the best nipples in the market all others followed afterwards. Thank you for making life easier for us

These Lansinoh NaturalWave nipples are soft, good quality, and easy to use. The shape feels very natural and helps my baby latch more comfortably compared with some other nipples we tried.

Worked well for my baby who was born with a lip and tongue tie

Love! Great dupe for Evenflo wide neck bottles. I actually preferred these more than the Evenflo medium flow nipples because these ones have a faster flow
