Did you know that 67% of babies can experience the symptoms of reflux within their first 4 months? VentAire bottles were specially designed with doctor recommended features and our VentAire technology that keeps colic and reflux at bay. Starting with the right bottle can minimize feeding issues for your baby. VentAire’s bottom vent technology channels air into the back of the bottle, not through the milk. And no vent in the nipple means no air mixing with the milk. The air-free bottom vent prevents air from getting into baby’s tummy and prevents vacuum within the bottle. Our ergonomic, upright angled bottle allows for easier upright feeding which can help prevent reflux* and even ear infections. BPA-free. PVC-free. Phthalate-free. *Pediatrics.aapublications.org – May 2013
