Philips AVENT nighttime pacifiers offer a durable soothing solution for children 6 to 18 months old. Glow-in-the-dark handles provide a gentle glow at night. The nipples are made of odor-free silicone, which is easy to sterilize and resists becoming sticky or misshapen. The special shape of these BPA-free pacifiers allows for healthy development of a baby's palate, teeth, and gums. The Philips AVENT nighttime pacifier features a collapsible nipple that works with the natural development of a baby's teeth and gums. The nipple is flat and drop-shaped, respecting the shape of your baby's palate, even when the pacifier is positioned upside down in the mouth.
