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

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.

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!

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.
