The Philips AVENT natural bottle helps to make bottle feeding more natural for your baby and you. The teat features an innovative petal design to encourage natural latch on similar to the breast, making it easy for your baby to combine breast and bottle feeding. Your baby will enjoy a comfortable and contented bottle feed. Made from BPA free material (polypropylene), the new Philips AVENT natural bottle is compatible with the majority of the Philips AVENT range, excluding the classic bottles. We advise to use the Philips AVENT natural bottles only with Philips AVENT natural feeding teats. The wide breast shaped teat promotes natural latch on similar to the breast and makes it easier for your baby to combine breast and bottle feeding. Petals inside the teat increase softness and flexibility without teat collapse so your baby will enjoy a more comfortable and contented feed. The innovative twin valve design reduces colic and discomfort by venting air into the bottle and not baby's tummy and due to the unique shape, the bottle is easy to hold and grip in any direction for maximum comfort, even for baby's tiny hands.
