The Natural Flex™ pacifier by Nûby™ Natural Touch™ features a unique system. The cherry shaped baglet flexes, stretches and moves like a mother's nipple during feeding. This pacifier is ideal to use during breastfeeding. The flexing movement helps to stimulate the natural sucking action of your baby. It will relax and calm down the baby more than a pacifier without this unique feature. The small nubs around the base of the baglet massage and soothe sore gums. They also allow a better air circulation around the mouth to prevent irritation. This version of the Cherry pacifier by Nûby™ Natural Touch™ is available in green.
