• Noticed it was very hard for the baby to get milk out. Feb 13, 2020

  • Initially worked well for our baby but after 10 weeks, baby would refuse to drink from this. Just seemed like the nipple made it too hard to suck milk. Feb 01, 2020

  • I want to love it but im still undecided. It's better than pace feeding. My baby has a strong suction so she still gets too much milk but less gagging than other bottles. its really expensive. Dec 23, 2019

  • I'm neutral because my son didn't love this bottle. I get the point but I found that with this bottle, I was constantly stopping milk from running out of his mouth. Not recommended. May 01, 2019

  • Both my son and daughter have a struggle with this bottle. This is one of the medela products I would stay clear of. Sometimes they can barely suck any milk or none at all that they get frustrated. Apr 28, 2019

    I was looking for a bottle nipple that would not cause nipple confusion. I was heading back to work but wanted to be able to breast feed when I was home. This worked great and they had no gas problems Apr 04, 2019

  • These nipples were really hard to figure out how to put together. Ended up using other nipples instead Jan 17, 2019

  • My son loved this bottle and preferred it over others. The only con is the price, as it is a bit expensive. Dec 27, 2018

  • I really wanted to love this bottle - in theory it sounds great. Once my son got the hang of it he would gulp milk faster than any other bottle and then projectile spit up 1-2 ounces :-( Nov 07, 2018

  • it didn't work my baby drink the bottle in less than 5 min because all flow. Sep 26, 2018

  • Difficult and confusing to assemble. Sep 17, 2018

    This nipple is expensive, and my baby wouldn't take it. I was very disappointed! It's very confusing to assemble, too. I would not recommend this unless your baby won't take anything else. Sep 13, 2018

  • My baby wouldn't take these bottles, and I think it's because the nipple was an odd shape Jul 31, 2018

  • Huge waste of money. These nipples are specialty and supposedly mimic natural breast feeding. Very expensive. The nipple is unusually long and he kept choking on it. Never drank from this successfully Jun 29, 2018

  • My daughter didn’t have a great latch when she came home. This nipple taught her how to nurse. She had to really latch on and create a flow in order to feed. She was able to nurse properly same day Jun 04, 2018

  • I loved the idea of this , but my baby couldn’t figure it out and there was a lot of wasted breastmilk Jun 01, 2018

  • My baby just hates this! Won't even try to duck, prefer other bottles. May 16, 2018

  • Works great to going from pumping to feeding! Apr 26, 2018

  • I love how much these nipples actually work like human nipples. The baby has to suck and work to pull the milk out at first. However, once the milk starts to come out, it flows pretty fast! Apr 11, 2018

  • My breastfed baby hated this nipple. The nipple is very hard and long, not natural feeling at all. It made her gag and she refused it after that Apr 08, 2018

    The calma nipple is rather elongated that it made my newborn daughter have a harder time taking a bottle (breastfed exclusively ) the flow is slow which is great but the nipple shaped awkwardly Apr 01, 2018

  • Needs a more like breast niple. Feb 22, 2018

    • Kelli J.

    • Staten Island, New York

    One of the only bottles my daughter will take! We have to dip it in expressed milk before she will latch on. Feb 20, 2018

  • Was NOT a fan. Baby gagged constantly with the long nipple. Was difficult to assemble and clean. Very expensive and doesn’t seem worth the investment. Feb 17, 2018

  • My daughter didn’t like this nipple. It was too long and gagged her Feb 11, 2018

  • Tried this bottle when I was looking for a good one for my reflux newborn. He really was not able to express milk from it. May work for others. Dec 21, 2017

    My baby hates this and won't drink much from it at all. Oct 28, 2017

  • Bought and returned before using. Didn’t realize they were so small. Aren’t even big enough for one feeding. Bags work better for storage since they fit a full bottle Oct 18, 2017

    • East Windsor, New Jersey

    My 1st daughter did not like this Jul 24, 2017

  • The bottle leaked a lot of the time even though it was correctly assembled, the lid also does not prevent leaks so you have to make sure it's always upright in your purse or diaper bag. Jul 01, 2017

  • Nipple was very hard. Baby wanted nothing to do with it. Difficult to clean as well. Don't waste your money. May 28, 2017

    • Aseky B.

    • Winter Springs , Florida

    My son would be drowning in milk. Even though he controls the amount of milk that comes out, he'd start choking on it because it was way too much! May 11, 2017

  • I bought this to help baby go between breast and bottle. She could never get the milk flowing from this nipple. We found another brand to work better May 09, 2017

  • Good idea, but I found the flow to be a little too fast for 0-3 month. Especially if it is meant to be more natural and make the baby "work for it." Baby would cough and choke from heavy flow. Apr 05, 2017

  • Great for breastfed babies Mar 10, 2017

  • Expensive. My daughter didn't take to this nipple. Difficult to clean and assemble. Mar 07, 2017

  • Once my son figured out how to use this he was gulping down the milk. It didn't help transition between breast and bottle. Feb 07, 2017

  • I just got this bottle and I'm still testing it, but so far it has a really fast flow or it leaks Feb 01, 2017

    • Alba V.

    • Boston , Massachusetts

    Not our favorite bottle at all, I have tried using on different occasions and my little will drink so fast that she gets gas. Its supposed to be easier to use for pace bottle feeding, but didn't work Jan 31, 2017

  • Newborn was okay with this but not cost effective. So many parts as well. Jan 30, 2017

  • My son hated these. The nipple is very hard and not natural at all. He's not picky with other nipples at all, so it was disappointing to spend the extra money on these and him not take to them. Jan 09, 2017

  • My baby hates it Jan 09, 2017

  • My baby would not take these nipples. I loved the idea too because I could use the same bottle I pumped into but she couldn't get milk out of them. Nov 13, 2016

  • This product is expensive but you only need a few - it does such a great job of mimicking the sucking action required at the breast! and naturally this helps with colic and gas! Nov 11, 2016

  • In theory this is great, my kiddo could care less that this was a pricier/"better" nipple. He just flat out refused it. Oct 14, 2016

  • My baby did not like this nipple. She dribbled when eating from it, plus there are multiple pieces that need to be taken apart and cleaned. Oct 06, 2016

  • Kind of expensive for a nipple. Baby hated it Oct 06, 2016

  • LOVE LOVE LOVE! These are the best bottles for breastfeeding support! Aug 24, 2016

  • Baby really can set the pace for the feeding. This prevents fussiness. Aug 05, 2016

  • love this. Recently bought this and it has been doing it's job. Medela makes amazing products for babies. Absolute must ! Aug 03, 2016
