The Orthodontic Silicone Nipple and plastic shield make them safe for your child's mouth, while the Team Logo And Colors on the "button" and shield respectively let everyone know who they're rooting for. These pacifiers have been quality and safety tested to be 100% BPA-free and are suitable for infants ages 3 months and up. To clean, use hot water and mild detergent and rinse thoroughly. WARNING: Do not tie the pacifier around the child's neck as it presents a strangulation danger.
