Medela Calma System
Includes 150 mL bottle & 2 lids
With Medela Calma, a baby can finally apply the same feeding behaviour learned at the breast, when consuming expressed human milk. This allows for seamless transition between breast and Calma, eliminating Nipple Confusion.

Just like when breastfeeding, baby latches onto the teat of Calma by creating
a vacuum. Once the vacuum has been established, the baby uses his or her
tongue to increase or decrease the level of the vacuum.  When the vacuum is
at baseline, milk will not flow through Calma. However, when a baby increases
the level of the vacuum, Calma allows the milk to pass through the teat into
the baby’s mouth.

  • Milk Flow Hole:  Milk flow membrane system ensures milk stays in the bottle until the baby chooses to feed by increasing the level of vacuum
  • Soft Bumps:  The soft bumps stabilize the outer layer and prevent the silicone from collapsing
  • Air Venting System:  Ensures bottle air pressure remains neutral at all times so milk release is dependent only on level of vacuum created by baby
  • Includes 150mL Medela bottle and 2 lids

Laura: a few months ago

Recommended by our midwives as the closest flow to breast and our baby has no problem going back and forth between bottle and breast. We have the medela pump too so it’s a great system all together.

Catherine: a few months ago

Just FYI, this item says it comes with 2 lids but it’s just the snap on flat lids for the bottle, not the actual nipple lid which I understood it was. So if you think your getting a great deal by getting 2 nipple lids your not. Fairly disappointed in the description of this as that’s very misleading. Also the nipple cover barely snaps on.

Annie: a few months ago

Very good quality. All of the parts are easy to clean. Compliments breastfeeding very well. The numbers on the bottle do start to come off after a few months of use.

Sally: about a year ago

This is a great nipple! Baby adapted to it quickly. It gives the baby a chance to take breaks in between gulps. Also easy to clean. I have 4 at home!

Catherine: more than a year ago

My baby likes this bottle and eats well from it. Doesn't have a problem going back to the breast.

Rachel: more than a year ago

Love the Medela Calma baby didn't get confused with breast and bottle because, its him who control the milk flow, easy to wash!

Jimena: more than a year ago

Great bottles, allowed baby to switch between nursing and bottle very easily. In fact, helped baby open mouth more and improve latch! As other reviewers said, it takes more time to wash because nipple has 3 parts (instead of 2 for example in avent bottles or 1 in other bottles) but that wouldn't stop me from recommending the bottle. Definitely worth the hassle if you're trying to avoid nipple confusion!

Rebekah: more than a year ago

I switch between nursing and bottle and really like this bottle because baby has to suck in order to get milk. My little guy has shown no confusion with switching. Bottle head is annoying to wash as pulls apart to 3 parts but wouldnt stop me from buying the product.

Andris: more than a year ago

Goof product. Only issue is that sometimes I can see milk flow before vacuum is applied (without the baby latching).

Mary: more than a year ago

Great product. Used this for my baby right from when she was born. We have been alternating between the calma and breastfeeding and it doesn't appear to have caused nipple confusion. If your baby has a strong suck, then s/he will get a lot of milk when feeding which makes it seem like milk flows a bit faster using this nipple versus say, the AVENT newborn low flow nipple.
