While breastfeeding, a baby is able to maintain a vacuum-like suction to the breast and is able to breathe efficiently to stay calm and relaxed during feeding. Calma, is a feeding device that mimics that same suction ability of a baby. The Medela Calma Innovation Feeding Solution is able to create the same vacuum for efficient milk flow, when in use. This is made possible by designing a device that responds to the same tongue movement of a breastfeeding baby. The breast-like feel of the Medela Calma Innovation Feeding Solution makes it the perfect option for busy moms on the go.
