The Philips Avent Ultra Air Day&Night SCF376/28 pacifier is designed for infants aged 6 to 18 months and features a symmetrical silicone nipple that adapts to the shape of the baby's palate. This model includes two pacifiers in color options of blue and green. The symmetrical design supports natural oral development, allows for free nasal breathing, and facilitates comfortable swallowing. The pacifier offers effective ventilation to keep it dry, as well as a glow-in-the-dark ring for easy visibility at night. Made from durable silicone material, this pacifier meets safety standards for infant products. The age-appropriate size ensures a proper fit and function, covering two developmental stages within the 6-18 month range. This pacifier model is the successor to previous Philips Avent designs and incorporates practical features for everyday use. The materials are easy to clean and maintain, with the silicone construction providing flexibility and durability. The symmetrical shape helps prevent dental development issues while offering comfort. The ventilation system reduces moisture buildup, and the glow-in-the-dark feature enhances visibility in low light conditions. A correct size selection according to the infant's age is recommended for optimal use and safety.
