The Philips Avent PP Natural Response bottles feature soft silicone nipples that support your baby's individual sucking behavior. The design of the nipples allows milk to flow only when your baby is actively drinking. This enables your baby to suck, swallow, and breathe at their own pace—just like breastfeeding. The Natural Response nipples are ideal for combining breastfeeding and bottle feeding. The particularly soft texture and wide shape of the nipple mimic the feel of a mother's breast. The anti-colic system reduces the risk of your baby swallowing air while drinking, thus preventing colic and discomfort. The optimal flow of food depends on how fast or slow your baby drinks. A slow flow is suitable for active, quick drinkers, while a fast flow is better for slow and steady drinkers. The package includes nipples size 2 (from birth) and size 3 (from 1 month). The exceptionally lightweight and sturdy bottles are easy to grip and hold— even in small hands. The wide bottle neck allows for easy filling and cleaning. Since the bottles consist of only a few parts, they can be quickly and easily assembled. The 9-piece starter set for newborns from Philips Avent includes 1 bottle warmer, 2 small bottles of 125 ml each, 2 large bottles of 260 ml each, 1 bottle and nipple brush, and 3 burp cloths measuring 80 x 80 cm. This set also makes a great gift idea for expectant or new parents.
