The Chicco Soother Physio Air 16-36 Months 2pk provides a soothing solution for toddlers aged 16 to 36 months. These pacifiers feature an orthodontic shape that promotes natural oral development and proper alignment of the palate, tongue, and teeth. The Physio Air design includes tiny holes for maximum airflow, reducing the risk of skin irritation and ensuring breathability. With two pacifiers in the pack, you have a spare on hand or can use them interchangeably. Chicco's Physio Air Soothers are made from safe and durable materials, providing comfort and reassurance for both parents and toddlers during those critical developmental stages.
