Setup & Assembly
Before first use, disassemble all parts and clean them thoroughly. Sterilize all components according to the cleaning instructions.
Assembly Steps:
- Ensure all parts are clean and sterilized.
- Insert the Natural Response nipple into the screw ring from the top, pulling it until it is securely seated.
- Place the assembled nipple and screw ring onto the bottle and twist clockwise until tight.
- Fill the bottle with the desired amount of milk or formula.
- Place the dome cap over the nipple to keep it hygienic when not in use.
Operating Instructions (Feeding)
The Natural Response nipple is designed to allow your baby to control the flow of milk, similar to breastfeeding. Milk will only be released when your baby actively compresses the nipple with their tongue and gums.
Feeding Guidance:
- Always check the milk temperature before feeding your baby.
- Position the nipple correctly in your baby's mouth, ensuring a wide latch.
- Observe your baby's feeding cues. They will pause to swallow and breathe, during which milk flow will stop, just like during breastfeeding.
- The bottle comes with a Medium Flow nipple (Flow 3). Philips Avent offers 5 different nipple flow rates (Extra Slow, Slow, Medium, Fast, Extra Fast) to match your baby's drinking rhythm.

Maintenance & Cleaning
Proper cleaning and sterilization are crucial for your baby's health.
Cleaning Instructions:
- Disassemble all parts of the bottle (bottle, nipple, screw ring, dome cap).
- Wash all components thoroughly in warm, soapy water using a soft brush or sponge. Ensure all milk residue is removed.
- Rinse all parts completely under clean running water.
- The bottle and its components are dishwasher safe (top rack only).
Sterilization:
After cleaning, sterilize all parts using one of the following methods:
- 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 a Philips Avent steam sterilizer or another suitable sterilizer according to its instructions.
- Microwave Sterilizer: Use a microwave sterilizer according to its instructions.
Store clean and sterilized parts in a dry, covered container.
Troubleshooting
- Milk not flowing or flowing too slowly:
- Ensure the nipple is correctly assembled and not blocked.
- Check if the nipple flow rate is appropriate for your baby's age and feeding style. It is natural for babies to take 2-3 tries to get milk flowing from a new bottle.
- Consider trying a higher flow nipple if your baby seems frustrated or takes a long time to feed.
- Milk flowing too fast or baby gulping:
- Ensure the nipple is correctly assembled.
- Consider trying a lower flow nipple if milk is leaking from your baby's mouth or they are gulping excessively.
- Colic or discomfort:
- The integrated anti-colic valve is designed to reduce air ingestion. Ensure it is clean and functioning correctly.
- Ensure your baby is latched properly to the nipple.
- Leakage:
- Ensure all parts are correctly assembled and tightened.
- Check the nipple and screw ring for any damage or wear. Replace if necessary.
