Philips Avent SCF186/28 orthodontic pacifiers soothe and comfort babies and toddlers 18+ months old. They feature bright, colorful designs. The orthodontic, collapsible and symmetrical nipples respect the natural development of baby's teeth and gums. Plus, they are made of tougher silicone than other Philips Avent pacifiers, for increased bite resistance. Each pacifier comes with a snap on hygienic cap. All Philips Avent pacifiers are made of silicone and are taste and odor-free. The silicone is smooth, transparent, easy to clean and doesn't get sticky. The nipple is strong, long-lasting and won't become misshapen or discolored over time. Can be sterilized using a Philips Avent sterilizer and is dishwasher safe.
