Check the VENT flow
Someone else commented on this same issue! I could not understand how the nipple that is flow 3 was slower than flow 2. I was like this makes NO SENSE! You sometimes have to open the vent yourself squeeze it from the inside and it works. Otherwise milk does not come out. Love love these bottles absolutely the best on the market.

Fast flow
The fast flow nipples are so firm compared to the medium flow which comes with the 8oz bottle. Baby never finish the bottle since using the fast flow ones.

Great Nipple, but Slowest Flow Still Too Fast
I have an exclusively breastfed baby that I want to get to accept bottles. Baby does like the feel and shape of the nipple, but chokes because the flow is still far too fast even with the slowest nipple flow.
1 reply from Lansinoh Team team - 9 months ago
Hi there! We do offer a Natural Wave Extra Slow and slow flow nipples (2S) which are designed to drip while inverted. This enables baby to learn to control the flow of milk. In order to slow the flow, we recommend holding the bottle horizontally and the baby more upright. Our medium (3M) and fast flow (4L) NaturalWave nipples do not drip while inverted but allow for more milk to flow through when baby is actively drinking. If you need further assistance please contact us at customerservice@lansinoh.com

Best bottle nip for babies with a tongue tie. Used these with my son and switched between breastfeeding and bottle feeding with ease. These are super easy to clean

even the slow flow is too fast for my 4 month old
I bought these bottles and tried to get the slowest nipple because we have been having nipple confusion. I really wanted to love these so bad, but the flow is so stinking fast that my baby is downing a 5 oz bottle in like 10 mins. which is wayyyyyyy faster than my breast. when I try to latch him, he screams because he wants the fast flow of the bottle. I'm so upset and want him to be able to go back and forth better. please make a slower flow nipple!!!

Slow nipple flow way too fast
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.

Too fast flow!!!
I purchased these for baby #3 after having two successful BF babies who also took bottles occasionally. I wanted to love these bottles so much because I loved the shape of the nipple but the flow is way too fast my baby would try to drink and be drowned. There was no way for her to stop the flow in order to breath which lead to so much frustration for mom and baby!! I'm so relieved that I'm not the only one to feel this way after reading these reviews. PLEASE make a slower flow.

Hello Elsa, Thank you for your feedback. Our slow flow nipples are specifically designed to support a baby's natural feeding rhythm, mimicking breastfeeding as closely as possible. We understand that every baby is different, and while our nipples work well for many families, we recognize they may not be the perfect fit for everyone. In order to help your baby learn how to handle the flow, we recommend holding the baby in a more upright fashion and holding the bottle more horizontally to decrease the dripping. If the flow speed doesn't meet your needs, we recommend exploring other options that might be better suited for your baby. We appreciate your understanding.

Helped with bottle refusal
My daughter refused bottles until switching to a faster flowing nipple. The nipple kept collapsing while my daughter was drinking her bottle, but eventually I figured out how to fix it. The opening needs to be on top so air can escape and if it still doesn’t fix the issues you need to make sure the little air hole is actually open on the inside lip of the nipple. Sometimes it just needs to be pinched a bit to open up.

Faster flow than others
Work well for breastfed baby, but leaks a bit due to faster flow than other brands

Hello Apack, Thank you for taking the time to leave this feedback on our Breastfeeding Bottles with Slow Flow NaturalWave nipples. We're sorry to hear about your experience. We designed our NaturalWave nipples to create an experience that is similar to that of the breast. Because the nipple stretches when a baby nurses, we wanted our NaturalWave nipple to mimic this so that transitioning between the bottle and breast would be easier. Our NaturalWave nipple is clinically proven to reduce nipple confusion. That said, our slow flow (2S) nipple is designed to drip while inverted, so this may explain the leaking that you described. Nonetheless, we welcome the opportunity to learn more about your experience. Please send an email to customerservice@lansinoh.com. We look forward to working with you.

Not slow flow!
Nipple shape is great. Baby latches on easily and switches from breast no problem. However, this is NOT a slow flow nipple despite its name. It is very fast. We have to stop and wipe her spit up every few gulps! It’s a faster flow than the default medium flow nipples we have from Lansinoh!

Hi there, Thank you for your feedback. Our slow flow nipples are specifically designed to support a baby's natural feeding rhythm, mimicking breastfeeding as closely as possible. Our 3M, medium flow nipple is not designed to drip like our 2S, Slow Flow Nipple. The medium flow nipple is designed to allow milk to flow when there is pressure on the nipple. This helps the baby to control the flow of milk and train their sucking ability. We understand that every baby is different, and while our nipples work well for many families, we recognize they may not be the perfect fit for everyone. In order to help your baby learn how to handle the flow, we recommend holding the baby in a more upright fashion and holding the bottle more horizontally to decrease the dripping.

Flow Rate
You'd think that with how many complaints and for how far back the complaints go about flow speed, lansinoh would surely make some adjustments. I'm guessing they manufactured way too many and can't afford to remake the nipples or are just a "the customer is always wrong" business.

Slow Flow still way too fast!
Love the shape and ease of these bottles but like almost every other review says, the slow flow is way too fast! Such a disappointment considering these are the closest to mimicking the breast. My breastfed baby now fusses when latched at night because my flow (which isn’t slow by any means) isn’t fast enough for her at night.

Need a slower nipple than slow flow
I love the lansinoh bottles and nipples…EXCEPT the flow. Much like other users, and quite honestly with the number of people that have had the same issue I don’t know why Lansinoh hasn’t made another slower version yet - but I digress, the slow flow is not even close to slow enough. I wouldn’t say I have a slow flow myself, and my 10 week old is gasping and choking. And for those saying “try to pace feed” etc….this is WITH pace feeding. The second I tilt the bottle it begins. It’s absurd as a level one pace. At least Pigeon has figured out the fix and is certainly capitalizing on all of these breastfeeding moms that need a slower flow bottle nipple. Highly recommend the 0+ ss nipple and it’s compatible with Lansinoh. Lansinoh- please take note- when this many people have the same issue, the problem isn’t us. It’s you. Please LISTEN to your customers.

Hello Mandy, Thank you for sharing your feedback on our NaturalWave nipple. We designed the slow (2S) flow nipple to mimic breastfeeding, which is why it drips when inverted. To help manage the flow, try holding the bottle more horizontally and your baby more upright. If this does not help, please wait until your baby is older to try the nipples again. We appreciate your input and will share your comments with our product development team for consideration.

Medium flow not taking out milk fast enough
Hello, my baby drinks so good with the slow flow but now is able to drink more and gets bored easily so we switch to the medium flow and she’s getting even more frustrated and drinks way less milk now. Please help.

Slow Flow is NOT Slow
Unsure why the slow flow complaints aren’t being taken seriously by company, but it’s very frustrating. My newborn won’t take a bottle, but this one went very well EXCEPT it was completely flooding her out. How is this similar to a breast when the flow is SO much faster? We just need a slower flow nipple option - similar to Dr Browns P and 1. Sitting her upright and pace feeding does not combat the incredibly fast flow of the 2s.

Hello Lola, Thank you for taking the time to provide your feedback. We are sorry to hear that you are not fully satisfied with our Natural Wave Nipples. We understand how important it is to find the right feeding solution for your newborn. Currently, our 2S is our slowest flow nipple. However, we recognize that every baby is different, and what works for one may not work for another. Consulting with your pediatrician or a lactation consultant could be helpful, as they might be able to provide further guidance on where to find different slow flow nipples or suggest alternative solutions to suit your baby's needs.

Great nipple shape for combo fed babies
I’ve been using Lansinoh bottles with my twins since they were born since we have to supplement with formula. We have no issue with the flow, they spill milk sometimes and it’s definitely not the nipple flow because one twin doesn’t spill a single drop while the other one every now and them soaks a bib. These promote a wide latch and I think it was one of the things that helped my twins latch onto the breast, they were born very small and had a hard time latching. We started with the smaller bottles and quickly realized that we needed the bigger ones, so we purchased multiple 2S nipples for the bigger bottles and that’s what we’re still using at almost 4 months. Also, a great hack is to purchase the Lansinoh nipples and use them with the Parents Choice wide neck bottles!!

Flow too fast? Try pigeon!
I keep seeing reviews about people complaining about the flow of these nipples. Lansinoh also owns pigeon and they have a SS flow nipple! Same shape and a lot slower of a flow!!
