Once you have expressed your milk, you need to choose the right way to feed your milk to your baby. You want to find an optimal solution that does not interfere with your breastfeeding. Calma is able to offer an innovative solution, enabling your baby to switch from breast to bottle and back. Your baby has his own natural feeding behaviour whilst on the breast and learns this from the very first time of feeding. With Calma your baby can feed, pause and breathe regularly. The milk will not flow unless a vacuum is created. It stops milk flow when the baby relaxes to pause and breathe. Also, your babys natural feeding behaviour will be maintained supporting easy transition back to the breast. Calma is easy to assemble and clean. It comes with 2 multi-lids that prevent spillage and close the bottle tightly, plus a protective cap.FeaturesAllows natural switching between breast and bottleOne size and shape fits allSafe drinking the baby does not swallow air during the feedRecommended for babies 0+ monthsINCLUDES: 1 Calma Teat (including cap) & 1 x Storage lidLOVED BY MOMS, RECOMMENDED BY DOCTORS: The world's leading brand in breastfeeding research.
