From the #1 Spanish bottle brand, Sauvinex has been beloved by parents for 40 years. Introducing the Suavinex Color Essence SX PRO™ Silicone Bottle, a high quality silicone bottle designed & made in Spain. This bottle features a unique internal structure which is entirely lined with silicone, meaning the milk or formula never touches plastic. This design works in conjuction with the revolutionary SX Pro anti-colic silicone nipple, which is designed with respect to the baby's changing oral development and is endorsed by the SEOP (Spanish Society of Pediatric Dentistry). The physiological shape of the nipple helps the tongue remain in the same natural position as when the baby is breast feeding, aiding in correct positioning of the mouth, tongue & jaw.
