Minbie offers exceptional support for the mother-baby breastfeeding bond. When newborns are fed from the Minbie bottle teats, 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 1month+ Slow Minbie teat size.
