In case you are wondering what CALMA is, below is some info related. Source from Medela website..:)
C
alma is 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.similar as with breastfeeding, your baby can
- drink, pause and breathe in its natural rhythm,
- create its individual vacuum through a combination of tongue and jaw movements,
- retain
its natural way of sucking, which supports an easy transition from
breastfeeding to feeding breastmilk with Calma and back to the breast.
