The Philips Avent Ultrastart Day&Night SCF075/18 pacifier is designed for infants from birth up to about 6 months, with a maximum recommended usage duration of up to 2 months. This pacifier is made from durable, high-quality silicone, a material known for its softness and flexibility. The symmetrical shield shape is designed to comfortably fit the baby's palate while allowing natural breathing through the nose and facilitating swallowing. A key feature is the effective ventilation system that helps maintain healthy skin in the mouth area. The pacifier has a ring that gently glows in low light, providing a subtle visual aid for nighttime use. It is important to choose a pacifier size that corresponds to the child's developmental stage. This model is a successor to a range of proven baby care products and focuses on providing a sense of comfort and security. The product is sold as a set with two units.
