ABOUT THISMinbie offers exceptional support for the mother-baby breastfeeding bond. When newborns are fed from the Minbie bottle nipples, they are practicing a proper anti-mastitis breastfeeding latch, for returning to the breast with a proper breastfeeding latch. To keep your newborn's instinctive breastfeeding technique free of confusion, we recommend only using Minbie when a bottle is needed from birth. Minbie is exceptionally Anti-Reflux and 3-way Anti-Colic. Contains the Minbie nipple XS especially for premature and full-term newborns supporting them to work to extract the milk and control latching, feeding, swallowing and breathing.
