NUK Space™ Glow-in-the-Dark Pacifiers have a revolutionary shield that has extra-large openings, enabling maximum airflow and allowing baby's gentle skin to breathe. The convenient glow-in-the-dark feature helps you and your little one find a lost pacifier at night. Designed to soothe them just like mom for an easy transition from breast to pacifier and back. This NUK Space pacifier is accepted by 96% of babies*, thanks to the unique nipple that reduces pressure on the teeth and jaw. The heart-shaped shield fits perfectly under baby's nose for easier breathing and prevents irritation. All pacifiers are BPA-free and dishwasher-safe (top rack only). *Based on Market Research, 2020, tested with 200 pacifier users
