Philips Avent Natural Glass Baby Bottles, Slow Flow, 4 oz, BPA-Free, 4-Pack

The Philips Avent Natural glass baby bottle is designed for first-time and experienced parents who prefer premium borosilicate glass while combining breast and bottle feeding. The Natural Response nipple releases milk only when baby actively drinks, letting baby control the pace like breastfeeding; when baby pauses to swallow and breathe, no milk flows. Its wide, soft and flexible breast-shaped nipple supports a comfortable latch, while the no-drip design helps prevent spills and lost milk. An integrated anti-colic valve sends air away from baby's tummy to reduce colic and discomfort. Premium borosilicate glass is BPA-free, heat and thermal shock resistant, so the bottle can be stored in the fridge, warmed, washed and sterilized with confidence. The ergonomic shape is comfortable to hold, and a few parts plus a wide bottleneck simplify filling, assembly and cleaning. This 4oz bottle includes a slow flow nipple (Flow 2) and is designed for use with Philips Avent Natural Response bottle nipples. Five nipple flow rates are available; age is a guide, while baby's drinking approach and feeding cues help determine when to move up or down in flow. It is the #1 Pediatrician recommended natural baby bottle¹, giving parents reassuring material durability without giving up a natural feeding rhythm. ¹ IQVIA Health ProVoice Survey 2025, USA
