Breastfed babies utilize a different set of oral motor muscles when feeding and latched on to mother. In contrast to the pursed lip, tight mouth grasp babies utilize on a conventional pacifier or bottle, the NinniCo. pacifier activates the muscles and oral movement required for breastfeeding. It requires an open mouthed grasp while the baby pulls the silicone nipple portion back to the soft palate of the baby’s mouth, while the tongue does the same wormlike motion to keep it in place.
