NaturalWave Baby Bottle Nipples, Extra Slow Flow, Size XS, 0+ Months, 4 Count – 100% Soft, Durable Silicone, Made Without BPA BPS, Anti-Colic, Supports Baby’s Developing Mouth and Teeth

These Lansinoh NaturalWave nipples feel noticeably high quality right out of the box. When cleaning them for the first time, I was pleasantly surprised by the silicone's soft but durable feel. Even after tons of feedings and cleanings, the feel remains that of quality. We chose the extra slow flow (XS) because our newborn struggles with acid reflux and also has a tongue-tie. This nipple made a real difference. The slower, more controlled flow helps him pace himself better, which means less gulping, fewer air bubbles, and much gentler feedings overall. Pairing these nipples, paced feeding, and holding him upright for 20min at LEAST has reduced his reflux episodes significantly. They’ve also been great for maintaining breastfeeding rhythm. The shape and resistance feel natural enough that switching between bottle and breast hasn’t caused any issues. Overall, These are high-quality nipples that are easy to clean and genuinely helped our baby feed more comfortably. We’re sticking with them.

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!

The Lansinoh NaturalWave (Extra Slow Flow, Size XS, 0+ Months) nipple has been a fantastic choice for our baby. It’s soft and flexible, making it very comfortable in the baby’s mouth, and the extra slow flow is just right—no overwhelming streams of milk, just a steady, manageable pace. We use it with Avent bottles and Maymom rings, and the setup has been completely leak-free. With a simple ring swap, it’s even compatible with other bottle brands like Philips Avent, which makes it super versatile. Overall, it’s an excellent option for parents looking for a gentle, reliable nipple that works seamlessly across different bottles.

Does not leak once on tight and very durable after dozens and dozens of washes/sterilizing. Flow is pretty spot on

The xs flow size and shape (pass the triangle test!) of these nipples were great for my breastfed baby going to daycare!

These are by far the best bottle nipples! They are so soft and stretchy. We have been using them for a couple months now and they clean up easily and look the same as the day they were bought. We use them in our glass Evenflo Balance Wide bottles! No leaking!

Worked well for my breastfed baby. It has a hole so the air can escape, nice quality and doesn’t cause nipple confusion.

These are nice and soft. The shape is great for my 1 month early girl. She had some issues removing milk, even from bottles, and these were prefect. That being said, we only use them if you have to now. Somehow, she can now power through these and down a 4 Oz bottle in under 3 min with them SS flow. She is an "enthusiastic drinker" Sometimes she will demand the easy button in the evening though, so we keep them on hand. We use the philips Avent glass bottles, they fit OK. It is loose in the ring so you CAN screw it on with a gap that will leak, although that isn't often.

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

Baby loves them, they work great - nice and soft.

These nipples are the closest that you can find to the breast. They are very soft and very flexible. Anyone that is trying to find a nipple that is the closest to the human nipple this would definitely be it. Really helps prevent nipple confusion. The only reason for the four star review is because the flow of these are too fast for a very young baby. The slow flow is similar to a medium flow. However, when I did complain to the company, they were kind enough to offer me the extra slow flow. I’m hopeful they start selling the extra slow flow in Canada also since these are very good and definitely deserve to be on the market more than any other. Plus side they are compatible with avent bottles although may not fit perfectly. Update: they finally listened and have XS flow now, was so excited when I saw that, that flow is perfect . These are hands down the best nipples

I got these to try with my breastfed baby for the occasional pumped bottle when we're on the go. We had previously been using the evenflo balance wide nipples, which while we liked the latch, were too firm and he wouldn't drink much. These are much softer and still encourage a wide latch (though not quite as wide). And even better - they're compatible with all the bottles we had gotten to be compatible with the other nipples! (Mam glass and Philips Avent glass - a little loose with this one but fine once screwed on).

Honestly the best nipples. My baby latches so well with them, the flow is just right reduces spit up during feeds compared to other brands.
