The Dr. Brown’s Specialty Feeding System is designed to assist infants with complicated oral feeding issues. This unique bottle/nipple/valve system is beneficial for infants with conditions such as cleft lip/palate and oro-neuromotor dysfunctions. The unidirectional flow valve allows infants to use their tongue and jaw movements to express and deliver fluid safely. The fully vented design creates a positive-pressure flow, preventing vacuum effects and reducing discomfort from air ingestion. This set includes two 8-ounce bottles, two Level 1 silicone nipples, two Level 2 silicone nipples, and a cleaning brush, making it a comprehensive solution for feeding challenges.
