Introduction
This instruction manual provides essential information for the safe and effective use, cleaning, and maintenance of your Philips Avent Natural Baby Bottles with Natural Response Nipples. These bottles are designed to support your baby's natural feeding rhythm, mimicking breastfeeding by releasing milk only when your baby actively drinks.
The Natural Response nipple features a unique opening and tip that allows your baby to control the pace of milk flow. When your baby pauses to swallow and breathe, milk flow stops, similar to natural breastfeeding. An integrated anti-colic valve helps reduce discomfort by directing air away from your baby's tummy.

Operating Instructions
Feeding with Natural Response Nipple
The Natural Response nipple is designed to work with your baby's natural feeding rhythm. Milk is released only when your baby actively compresses the nipple with their tongue and gums, similar to how they would extract milk from the breast.

When your baby pauses to swallow and breathe, the milk flow will stop. This allows for a more controlled and comfortable feeding experience, reducing the risk of overfeeding or gulping.

Combining Breast and Bottle Feeding
The wide, soft, and flexible breast-shaped nipple is designed to mimic the shape and feel of a breast, making it easier for your baby to latch on and transition between breast and bottle feeding.

Nipple Flow Rates
Philips Avent Natural Response nipples are available in various flow rates to match your baby's developmental stage and feeding preferences. This product includes Slow Flow (Flow 2) nipples, suitable for newborns and infants 0-3 months.

Choosing the correct flow rate is important. While age is a general guide, observe your baby's feeding cues:
- Try a lower flow: If milk is leaking from your baby's mouth or your baby is gulping.
- Start with the nipple that comes with the bottle: This is typically appropriate for the indicated age range.
- Try a higher flow: If your baby is playing with the nipple instead of drinking or seems frustrated.

Cleaning and Maintenance
Cleaning
For hygiene, disassemble all parts immediately after each use and clean them thoroughly. The Philips Avent Natural Baby Bottles are dishwasher safe (top rack only). For hand washing, use warm soapy water and a soft brush to clean all components. Ensure all milk residue is removed, especially from the nipple and anti-colic valve.
Sterilization
Sterilize all cleaned components before each use for babies up to 12 months old. You can sterilize using one of the following methods:
- Boiling: Place disassembled parts in boiling water for 5 minutes. Ensure there is enough water to prevent parts from touching the bottom or sides of the pot.
- Steam Sterilizer: Use a Philips Avent steam sterilizer or another suitable sterilizer according to its instructions.
- Microwave Sterilizer: Use a microwave sterilizer according to its instructions.
Always allow parts to cool before handling and ensure they are dry before storage.
Troubleshooting
- Baby not taking the bottle: It is natural for a baby to take 2-3 tries to get milk flowing from a new bottle. Be patient and try different feeding positions. Ensure the nipple flow rate is appropriate for your baby's age and feeding style.
- Colic or discomfort: The integrated anti-colic valve is designed to reduce colic by venting air away from your baby's tummy. Ensure the valve is clean and properly assembled. If discomfort persists, consult a healthcare professional.
- Milk leakage: The no-drip nipple design helps prevent lost milk. Ensure the nipple is correctly inserted into the screw ring and the screw ring is tightened securely onto the bottle. Check for any damage to the nipple or bottle components.
