A revolutionary new feeding solution designed exclusively for breastfed babies. With the Calma feeding solution, a baby can finally apply the same feeding behaviour learned at the breast, when consuming expressed breastmilk. This allows for seamless transition between breast and Calma, and back to breast again.

  • Baby maintains control of feeding session
  • Breastmilk flow stops when baby wants to pause & breathe
  • Just like mothers breast stays the same throughout the entire breastfeeding duration, so does Calma


Baby will take the bottle in a similar way to breastfeeding! Very impressed.


Sharing Feeding Responsibilities

Research shows that support from partner and/or family has a direct impact on the length of time mom will breastfeed and the quality of the experience. more

Sharing Feeding Responsibilities

This new feeding solution ensures that babies do not have to change their natural feeding behaviour. Whether you breastfeed or use Calma - the milk flows when the baby "works" for it.

How babies breastfeed

Our latest studies with researchers from the University of Western Australia show that creating a vacuum is essential to successfully breastfeed. Babies learn very early on that they have to produce a vacuum for the breastmilk to flow by using a tongue up and tongue down motion. Their natural way of sucking requires intensive work during breastfeeding!

How it works

Just like when breastfeeding, baby latches onto the Calma feeding solution by creating suction. Once suction has been established, the baby uses their tongue to increase or decrease the level of suction. When suction is at baseline (low level of suction), breastmilk will not flow through Calma. However, when a baby increases the level of suction, breastmilk will start to flow at the speed and quantity baby decides.

Conventional nipples accelerate an unnatural technique

Conventional nipples change the mechanics around how your baby feeds, which essentially means your baby has to learn a new method for feeding. Usually, this feeding method requires less work on the part of your baby, so over time they find it “easier” and sometimes will not want to go back to the “harder” feeding method needed at the breast. This harder feeding method is critical for helping in the proper jaw development for your baby, and without it, your baby can be more prone to developing ear infections and malocclusion.
