Lansinoh NaturalWave Baby Bottle Nipples, Anti Colic, Medium Flow, Size M, 2 Count

Love the shape of the nipples and it gives baby very similar latch to breastfeeding, however the slow flow nipple is way too fast. I do paced feeding, holding the bottle horizontal and sitting baby up and its still way too fast. These would be perfect with a slower flow nipple.

Good flow especially for thick consistencyformula

I delivered very prematurely and have a very low milk supply, so my babe has to work pretty hard to get milk from my breast. I love the shape of these nipples and had high hopes for this bottle to be a solution to help my baby continue to love a breast that doesn't feed him a ton of milk. Instead, these nipples drown him: he gags and chokes and spills milk around the nipple and ultimately spits up from all the air he takes in while gasping to keep up with the flow. This is true even when following the recommendations to hold baby more upright and bottle more horizontal. There is just no way to adequately slow thr flow for my baby. As comparison, Dr. Browns offer three levels of slow-flow: preemie, transitional, and level 1; Lanisoh slow-flow is much faster than Dr. Browns level 1. While I like the nipple shape and ease of assembly of these Lanisoh bottles much better than any other bottles we've tried, I'm disappointed that a bottle specifically designed to help with breast feeding wouldn't offer a nipple appropriate for baby-mom pairs like us who work very hard to maintain the small amount of breast feeding we can but depend on bottles to get adequately fed. Like the many others who are discouraged by a supposedly breast-like bottle that only represents some gold standard breast, I implore Lanisoh to make an ultra slow flow nipple so those of us with slower-flowing milk and slower-eating babies can take advantage of this otherwise excellent bottle.

I purchased 3 packs and 4 of the 6 nipples are NOT slow flow. All 3 packages were labeled as Slow Flow and all 3 had at least 1 nipple that either drips or streams out breastmilk/formula. Not what I expected for a well-known name in breastfeeding supplies.

After researching looking for a bottle nipple that would help with my breast fed baby these worked exactly as intended. However some false information led me to believe they would fit in my dr.brown wide neck bottles, they did not. I was pleasantly surprised to find that they fit almost perfectly in the MAM bottles instead though. Enough that they do not leak. 4 stars only due to the fact that the shipping time was weeks. But it was the only place I could find the Lansinoh nipples at a reasonable price since I could not find in store.
