Mesh crib liners are breathable fabric barriers designed to line the inside of a crib. They help prevent babies from getting their limbs stuck between crib slats while allowing air circulation. This feature aims to enhance safety and comfort for infants during sleep. These liners are typically made from soft, lightweight materials that are easy to clean. Unlike traditional bumpers, which can pose suffocation risks, mesh crib liners provide a safer alternative by reducing the risk of entrapment while maintaining visibility for parents to monitor their baby.
