Product Overview
The Philips Avent Natural baby bottles are designed to support your baby's natural drinking rhythm, mimicking breastfeeding. The unique Natural Response nipple releases milk only when your baby actively drinks, allowing them to control the pace of the milk flow. This design helps prevent spills and reduces colic and discomfort by keeping air away from your baby's tummy.

Usage Instructions
The Natural Response nipple is designed to work with your baby's natural feeding rhythm. Milk is released only when your baby actively sucks, and flow stops when they pause to swallow and breathe, similar to breastfeeding. This allows your baby to control the pace of feeding.

Choosing the Right Nipple Flow Rate:
Philips Avent Natural bottles offer various nipple flow rates to match your baby's growth and feeding style. While age is a guide, observe your baby's feeding cues to determine the appropriate flow:
- Start with the nipple that comes with the bottle (Medium Flow, Flow 3).
- Try a lower flow: If milk is leaking from your baby's mouth or your baby is gulping.
- Try a higher flow: If your baby is playing with the nipple instead of drinking or seems frustrated.

- Bottle leaking: Ensure all parts (nipple, screw ring, and bottle) are assembled correctly and tightened securely. A loose connection can cause leaks.
- Baby struggling with flow (too fast/too slow): Refer to the
