Philips AVENT SCF178 Freeflow pacifiers are designed to provide extra airflow for your baby's skin, ensuring comfort and reducing irritation. The orthodontic, collapsible, and symmetrical nipples respect the natural development of your baby's palate, teeth, and gums, even when the pacifier is upside down in their mouth. Made from taste- and odor-free silicone, these pacifiers are accepted by most babies. The snap-on hygienic cap keeps the sterilized nipples clean, and the pacifiers are dishwasher safe for easy cleaning.
