Introducing Calma: Designed exclusively for breastmilk feeding.

Switching from bottle back to breast has never been easier. Calma was developed using evidence-based research on babies' natural feeding behavior so you can enjoy your breastfeeding bond longer.

With Calma, the milk will only flow if your baby works and creates vacuum to remove the milk. This enables the feeding behavior learned at the breast to be used with Calma.

Tips for breastmilk feeding with Calma

Features

Benefits

  • Vented nipple
  • Helps avoid gassiness as the bottle is vented through our unique air control system.
  • Mimics natural feeding behavior
  • Supports easy transition from bottle to breast. Research has shown that with Calma, your baby is able to maintain the learned feeding behavior that your baby exhibits when breastfeeding.
  • Flow control valve
  • Allows baby to control milk flow. Milk only flows when baby creates a vacuum.
  • Calma doesn't drip
  • You can turn Calma upside down and it still won't drip. Your baby needs to apply a certain level of vacuum in order to get milk out.
  • One size/shape nipple
  • For all stages of breastmilk feeding. The flow, shape and length of Calma are designed to suit your baby's needs as your baby grows.
  • Compatible with all Medela breastmilk bottles
  • Breastfeeding must be well established before introducing Calma

I had quite a bit of trouble establishing a milk supply and started supplementing around two months. I started out with a standard nipple and my baby started to prefer it over the breast. Once i used this nipple he transferred from breast to bottle and vice versa beautifully. I ordered two so I would generally have one clean. It is definitely worth a try also if you find other nipples have a flow that is too fast.

What formula do you use to supplement? Do you shake the formula in the bottle or separate? I had to switch to formula but I'm struggling to find the perfect bottle for my son. He seems to enjoy the Dr. Browns but he still has some issue even after changing to very slow flow nipples.

I had a really hard time nursing for the first month after my daughter was born. I really wanted to breast feed exclusively, but she lost weight and it was incredibly painful while she was learning how to latch. I was so grateful to the home health nurse who told me to nurse on one side and pump the other each day so that by breasts could heal. These nipples saved us. My daughter is almost a year old now, and we have been extremely successful with breast feeding. I believe part of our success is that she didn't get accustomed to nipples that dripped without her sucking. Thanks you Medela! Yet another amazing product to support moms and healthy babies!!

Been a fan of Medela pumps and bottles since my daughter was born in 2011. Calma didn't exist then. I noticed there was a bit of frustration when going from bottle to breast because she had to work for the milk -- almost like she'd get confused between the two and not understand why one would flow so easily and she'd have to work for the other. So when my son was born (July 2013) I got the Calma nipples to see how well they imitate nature. I LOVE THEM. There is no frustration when he goes back on the breast since the Calma won't release milk unless he does the work to create the vacuum suction. Plus, there is no fear of choking from the milk flowing too fast since he controls the flow with his suction. They ARE pricey, but the investment is worth it since the nipples are ALL STAGE, meaning you won't have to buy nipples for a stronger flow as baby grows. Baby controls the flow so you can use these nipples for as long as baby is on the bottle!

I started my breastfed baby on this bottle for the first time at 3 weeks because unlike with my first, I had to return to work right away :(. The first time, she took to it immediately and finished it, so I think the design is as close to natural as it gets for a bottle, which due to their research and breast-is best approach, is why I immediately went to Medela over other brands, even though the bottle is more expensive. The second time, a few days later, and again 2 weeks after that, she did not take to it so easily, but I don't think this can be attributed to the bottle itself. My sister-in-law and my mom were feeding her on those occasions, and she did take it when I came home, warmed up the milk (don't think it was warm enough the other 2 times), and did the following... I heat 3-4 oz. of my frozen milk in a breastmilk bag by filling up a medium sized stainless steel mixing bowl full of water from the tap, on all the way hot. I fill the bowl up twice (the second time after it has liquified). This only takes a total of about 6 minutes since it's a small amount, and not more than she will drink per feeding anyway. The nipple on the bottle is pretty long, so I find it most effective to start with about half to 2/3 of it in her mouth. That way, she figures out how to start sucking on it and get the milk flowing. Once it is flowing and her sucking reflex intensifies, she is more receptive to taking the rest of it in her mouth, and actually does so on her own (love nature!). She will gag if it just gets stuck into her mouth all the way right off the bat, which totally makes sense, if you think about it. I've had no trouble going back and forth between the breast and the bottle, so I really like it. It's a great bottle for any attentive, loving mother who considers her baby's experience, as every loving attentive mother does, and can communicate that to a caregiver if necessary. It isn't clear in the marketing, so I wanted to mention that although you can purchase a Calma bottle set, the nipple device does work with breastmilk storage bottles. Oh, and also, if you have leakage problems, check to make sure the silicone nipple wraps all the way over the rim of the yellow plastic flow device.

My nanny uses this with my baby to feed him breastmilk from a bottle when I am at work. He does great with it, and we have no difficulty breastfeeding once I get home. So glad to have this!

I had to go back to work full time, so we were trying to find a good option for easy back and forth transition. My son will suck down a 3 oz bottle in less than 15 minutes. We tried multiple bottles and nipple. we finally tried the Calma nipple and he did really well with it. He still eats very fast, but isn't choking like he did with the other bottles

My son was born 6 weeks early (Dec. 26, 2012). After finally being released from the NICU he came home at 4.9 lbs! I was just BF when we came home and I thought we were doing great, but we had a Dr. appt just 4 days later and he was down to 4.6 lb (not good for a preemie). So the Dr. recommended switching to formula (I was devistated!). We switched but every feeding he was choking due to the constant flow coming out, even with the slow flow nipples. I heard about the Calma so I purchased 1 to see if it would work with formula. Oh my goodness! It was amazing! He is now just over 6 lb!!!!!! I am always talking up Medela in general but am very excited about the Calma Nipple!!!!! Now we have 5 and I will be purchasing more soon! :-)

My daughter was breastfeeding and needed supplements, every other bottle nipple she leaked everywhere... level 1 nipples had to much flow! these nipples are amazing and she has been doing wonderful with them! I highly recommend them!
Jacqueline Holmes More than 1 year ago
My daughter and I were having trouble with breastfeeding in the beginning. My milk didn't come in until day 6. She was starving and wanted instant results. I had purchased the Calma bottle prior to her birth. I had read reviews knowing she had to be in more of a seated position than leaning back with the bottle. We ended up using this bottle with formula and it ended up being the best transition between breast and bottle. She had to work to get the formula out as she would with nursing. I was worried if we had a regular nipple, she would prefer that to the breast. This nipple relieved most of my fears. I am so glad Medela has made Calma and will never use another type of bottle or nipple!!!

My daughter is BF but when we are out I want to use pumped milk so I was not try to find a place to feed her. And all the so called Breast milk bottles would cause her reflux to go wild because the flow was way to fast even with the slow flow nipples. So our pedi recommend the Calma and after a ton of research I took leap of faith and it was the best thing we ever did she will take a bottle no problem know it did take me priming the nipple for the first coulp of time but now she does not have any trouble. And her reflux has gotten better when she has a bottle. And we even got to demo the nipple for the lactation department.

When I first learned about the Calma bottle, I was so excited to try it. I was relieved that the bottle lived up to the hype! I first used the bottle when my baby girl was 7 weeks old. She is exclusively breastfed, but I needed her to be able to use a bottle when I was away 2 or 3 times a week. It took her several attempts to get the hang of it (just like breastfeeding did), but she is now drinking breastmilk from the Calma bottle easily and happily. The best part is that she transitions back to the breast without any trouble, which was a fear I had since it didn't go so well without Calma with my two-year old son. I won't use any other bottle again...EVER! I will definitely recommend this product to all of my nursing friends.

what did you use when you started putting cereal in the bottle??? I love the calma bottle too but cereal wont work with it ...
Lynne Munger More than 1 year ago
I first introduced this bottle to my son at 3 months - he was exclusively breastfed. After several attempts to find a bottle that he liked and a lot of money spent on empty bottles in my cabinet I found Calma when ordering supplies for my pump to go back to work. He took to the nipple with no problem and can switch back and forth with ease. I like that my son can control the flow so that he doesn't get frustrated. I could not be happier and it's probably the best $20 I have spent.....should have started at Medela first.
Heather Sherwood More than 1 year ago
I have been so happy with the calma nipple. My son doesn't spit up like he did with the regular nipple. It has even helped him when he nurses to be more efficient. It does require some stronger sucking muscles but it was exactly what we needed. I'm so happy with this product & really all of the medela products I have used!

As a NICU nurse and lactation counselor I was excited to try the calma with my first baby. I was hoping not to have to use it for a while and exclusively breastfeed, but due to breastmilk jaundice had to change my son to formula / bottle fed for 48 hours at 1 week of age. I was affraid he wouldn't want to breastfeed again after the 48 hours but he transitioned back just fine, and has been able to go between breast and bottle without a problem ever since. The flow of the calma is not an issue for my son. I have always been impressed with Medela as a company through working with them in my lactation counselor role. As a mother I was equally impressed when I called the customer support line when the middle peice of the calma nipple got a hole in it. Medela customer support was great and sent another nipple out to me free of charge. Thanks Medela!

My son is 7-weeks-old and was exclusively breastfed for the first 6 weeks, until he caught a cold from my daughter that turned into a bad respiratory infection and caused him to be admitted to the hospital, because he would not eat and was dehydrated. They gave him saline and glucose via IV to rehydrate him and I pumped my milk until he was ready to eat again. The doctor wanted me to feed him through a bottle, so we could gauge how much milk he was getting. Well, I didn't want to use the regular rubber nipples they give at the hospital, because I was afraid he'd get nipple confusion. So, the first bottle I tried was the First Years Breastflow bottle which advertises that it mimics actual breastfeeding, however, he HATED the nipple and rejected it. Next, we tried the regular slow flow Medela nipple and he took it, but I didn't like it because it dripped even when he wasn't sucking and let out too much milk. So, I was surfing the Medela web site and saw the advertisement for the Calma Nipple. I went and purchased two, but only opened one, just in case he rejected it (so I could take the other back). He loved this nipple. He caught on right away. See, I have really large nipples, so the length of the Calma is not a problem for him. I also like the fact that he has to work for his milk, just like the breast. And since this nipple is more firm than the breast, he has to suck a little bit harder to get the milk. This has actually helped to improve his regular breastfeeding latch. Now, he transitions back and forth from breast to bottle like a pro. I love this nipple and would definitely recommend it to nursing moms!!!

Hen I first started using calms I noticed that yes the nipple was not at all an ideal feeling or looking nipple. My daughter at first spit it out, I then remembered that a nurse had told me in order for baby to get the suckling motion, you have to rub the nipple against the roof of the mouth. I did that and instantly she got the hang of it. I love it, she actually has to work to get her food. Unlike regular bottle she can just nibble on and milk comes spilling out. I love this bottle it was defiantly money well spent!
Adele LaFontaine More than 1 year ago
As I am getting ready to go back to work, I needed to introduce the bottle to my daughter. As I read the reviews I do agree that the milk comes out a little fast, but my daughter has adjusted just well. I do like that I have been able to go from bottle to breast with no problem throughout the day. The only downside to the price.
Gavi Castroalvarezdebrito More than 1 year ago
I only bought one because I didn't know if it would work, and now I need more!! For those saying it's too long, during the first minutes of feeding my baby would just suck the very tip of the Calma, but eventually he gets the whole nipple in his mouth.

I love this bottle. I first heard about it from a woman in my breast feeding support group and I have to say it was the best $20 I ever spent. My son doesn't prefer the bottle over the breast but he does not have a problem with switching back and forth. I was super hesitant on giving him a bottle but I introduced this bottle to him at 2 weeks old and he does great. I wish it was a little harder for him to get the milk out because he makes a bit of a mess when i feed him with the bottle but I just make sure to have a bib and soft towel in hand to clean up as he's a messy eater. I would definitely recommend this bottle to all breastfeeding and non breast feeding mothers. Great Product

My baby was admitted to hospital due to Jaundice (Day 4-6), and during that period of time, there was no choice but to put her on bottle. Was so afraid she will have nipple confusion and so we tried Calma (introduced to us at a Medela BF forum) ... When she came home, she was superb moving between breast and bottle. I believe her latching skills actually improved after using the bottle.
Zula Mala More than 1 year ago
My baby is little over 5 weeks old and until now exclusivly BF. I was so affraid of her refusing to take a bottle and/or have nipple confusion. But we tried Calma and everything went super smooth! She did great. Just remember try this nipple before any other as recommended for best results. I am thrilled that Calma is finally in US!

My son (born Sept. 5 '12)was losing weight/not gaining for 3 weeks and fussy with reg. bottles after one week he has gained 3 ounces.
Anady Jensen More than 1 year ago
I look forward to try this one!! My son used the Breast Flow system, which worked, but the nipple kept collapsing on him. I've been patiently waiting for someone to come out with a new design that works. I'm blessed right now that my daughter, being diagnosed with a heart condition so bottle feeding has been a must to ensure she doesn't burn to many calories while feeding, easily switches from the current Medela nipples to breast. I'm so excited to try I look forward to having a our next bundle. Gotta wait a bit cause she's only 2 months.
Debbie Wingo More than 1 year ago
I would love to review this!!! I have been wondering how long it would be until someone looked at how a baby naturally nurses and create a bottle that will work. I had a baby 3 years ago that I NEEDED this bottle to train him with until he got stronger. But I am having a baby in about 3 weeks and I would love to try this bottle!!

My daughter has been using the Medela Calma Nipple since she was about 3.5 weeks. It was extremely helpful in helping her work on her latch, as she had to work for the milk. I helped with her breast feeding. The bottle nipple does mimic the shape and length of a breast nipple during breast feeding. She is 7.5 months now and still enjoying using it. The air holes do get blocked and does not allow the milk to come out, so she would suck and get nothing. I use a needle now to ensure that the whole stays free and the flow has been great. The milk does come out of the nipple at times when we shake the formula. I bought one nipple that has a different ring that holds the cap better, however the 4 others I bought take some practice to click the cap on. I wish that you could buy a nipple with an 8oz bottle, as my daughter grew out of the 5 oz very quickly. I also wish that Medela had a 10+oz bottle. I bought Nuk bottles and the nipples fit well, however the Medela storage caps do not fully seal properly. So the Nuk bottle will leak if not stored straight up (e.g. in your diaper bag). I had some difficulty with one part of the Calma nipple, and Medela would not replace it and does not have replacement parts to buy for this nipple. So I kept the good parts just in case one of my other nipples breaks down. It is so expensive, I was not impressed that Medela would not be as helpful as other baby product companies. I have had friends that had free stroller replacements, and I just needed one part to make the nipple work.
