The wide breast-shaped teat promotes natural latch on similar to the breast, making it easy for your baby to combine breast and bottle feeding. Its natural shape helps the baby to continue the same tongue movement used at the breast. Petals inside the teat increase softness and flexibility without teat collapse. Your baby will enjoy a more comfortable and contented feed. Innovative twin valve design reduces colic and discomfort by venting air into the bottle and not baby’s tummy. This makes feeding comfortable for baby. 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. As a new parent, your little one’s health and well-being is your top-most priority. Rest assured you’re giving baby the best–the Philips Avent Natural feeding bottle is made of BPA-free (following EU directive (2011/8/EU) material (polypropylene). Philips Avent products are compatible with one another and are easily interchangeable, aiding the transition from your newborn to toddler. Bottles and teats can be used with the Philips Avent Comfort breast pump, storage containers, cups, sterilizers, and bottle warmer. The Natural feeding bottle is compatible with the majority of the Philips Avent range, excluding the Classic bottles.
