Pacifeeder® hands-free baby bottle promotes doctor recommended semi-upright feeding positions to help reduce ear infections. Our 2-way rotating strap helps Pacifeeder attach to any car seat, stroller, baby carrier, etc. Our SmartFlow™ system adjusts flow based on baby's needs and prevents nipple from leaking (no need for various flow nipples). Only Pacifeeder's nipple stays full of liquid until the bottle is empty to reduce ingestion of air (reducing colic). And of course, we protect our liquid flow tube with our patented FlexGuard™ to prevent baby form disconnecting the system. And last but not least, using any standard nipple you can quickly convert Pacifeeder to a regular baby bottle.
