Introduction
This manual provides essential instructions for the safe and effective use, assembly, cleaning, and maintenance of your Philips Avent Natural Response Baby Feeding Bottles.

The integrated AirFree vent system is engineered to reduce air ingestion, thereby minimizing colic, gas, and reflux.
Key Features
- Natural Response Nipple: Engineered to release milk only when the baby actively sucks, allowing for a natural drinking, swallowing, and breathing rhythm similar to breastfeeding.

- Ergonomic Design: The bottle's shape is easy for both parents and tiny hands to grip, providing maximum comfort during feeding.
- BPA-Free Materials: All components are made from BPA-free materials, ensuring safety for your baby.
- Easy to Clean and Assemble: Features a wide bottle neck for easy filling and cleaning, with minimal parts for quick assembly.
Product Overview

Setup and Assembly
- Disassemble: Before first use, completely disassemble all bottle components: bottle, screw ring, nipple, and AirFree vent.
- Clean and Sterilize: Thoroughly clean and sterilize all parts according to the 'Maintenance and Cleaning' section.
- Assemble Nipple: Pull the nipple through the screw ring until it is securely seated. Ensure the nipple is not twisted or pulled too far.
- Assemble AirFree Vent: Insert the AirFree vent into the bottle. Ensure the vent is fully seated and aligned with the bottle opening.
- Attach Screw Ring: Screw the assembled nipple and screw ring onto the bottle until secure. Do not overtighten.
Operating Instructions
- Prepare Formula/Milk: Prepare formula or express breast milk according to manufacturer's instructions or healthcare professional's advice.
- Fill Bottle: Pour the prepared milk into the bottle. Ensure the AirFree vent is correctly positioned if using.
- Check Temperature: Always check the milk temperature before feeding by dripping a few drops onto your wrist. It should feel lukewarm.
- Position Baby: Hold your baby in a comfortable, upright position.
- Initiate Feeding: Gently place the nipple in your baby's mouth. The Natural Response nipple is designed to only release milk when your baby actively sucks.
- Monitor Feeding: Observe your baby's feeding cues. Allow them to feed at their own pace, pausing as needed.
Maintenance and Cleaning
Proper cleaning and sterilization are crucial for your baby's health. Always wash all parts immediately after each use.
Cleaning Instructions:
- Disassemble: Separate all components of the bottle.
- Rinse: Rinse all parts under cold running water to remove any milk residue.
- Wash: Wash all parts thoroughly with warm soapy water using a clean bottle brush. Pay special attention to the nipple and AirFree vent to ensure no milk residue remains. The bottles are also dishwasher safe (top rack only).
- Rinse Again: Rinse all parts thoroughly with clean water.
Sterilization Methods:
Sterilize all cleaned parts before each use for babies up to 12 months old. Common sterilization methods include:
- Boiling: Place all disassembled parts in a pot of boiling water for 5 minutes. Ensure parts do not touch the sides of the pot to prevent damage.
- Steam Sterilizer: Use an electric or microwave steam sterilizer according to its instructions.
- Cold Water Sterilization: Use sterilization tablets/liquid according to their instructions.
After sterilization, allow parts to cool and dry in a clean, covered container. Store assembled bottles in a clean, dry place.
Troubleshooting
- Slow Milk Flow: Check if the nipple is correctly assembled and not twisted. Ensure the vent hole in the nipple is clear. If the issue persists, consider a nipple with a faster flow rate suitable for your baby's age and feeding needs.
- Fast Milk Flow/Leaking: Ensure the nipple is securely pulled through the screw ring and the screw ring is tightened correctly onto the bottle. Check for any tears or damage to the nipple.
- Baby Shows Signs of Colic/Gas: Ensure the AirFree vent is correctly assembled and positioned. The vent should be pointing upwards during feeding to keep air away from the nipple.
- Difficulty Latching: Ensure the nipple is fully in your baby's mouth. The wide, breast-shaped nipple is designed for a natural latch. If issues persist, consult a healthcare professional or lactation consultant.
- Bottle Leaks During Travel: Ensure all parts are tightly assembled. For travel, consider using the sealing disc (if included) or a travel cap to prevent leaks.
