1. Introduction
Thank you for choosing the Philips Avent Anti-colic Bottle with AirFree Vent. This bottle is designed to help reduce colic, gas, and reflux by keeping air away from your baby's tummy. Its unique AirFree vent ensures that the nipple stays full of milk, not air, even when held horizontally. This manual provides essential information for the safe and effective use of your new baby bottle.

4. Setup and Assembly
Before first use, disassemble all parts and clean them thoroughly as described in the "Cleaning and Maintenance" section.
4.1 Assembling the Bottle with AirFree Vent
- Insert the AirFree vent into the bottle body. Ensure the vent is securely seated.
- Place the nipple into the screw ring. Pull the nipple through until it is firmly seated.
- Screw the assembled nipple and screw ring onto the bottle body. Ensure it is tightened securely to prevent leaks.
- Place the cap over the nipple for hygiene and travel.
4.2 Assembling the Bottle Without AirFree Vent (Optional)
The Philips Avent Anti-colic bottle can also be used without the AirFree vent. Simply assemble the nipple and screw ring directly onto the bottle body.

Figure 4.1: Bottle assembly options: with or without the AirFree vent.
5. Operating Instructions
5.1 Filling the Bottle
- Prepare formula or breast milk according to instructions.
- Fill the bottle with the desired amount of liquid.
- Ensure the AirFree vent is properly inserted if you intend to use it.
- Securely attach the nipple and screw ring assembly.
5.2 Feeding Your Baby
- When feeding with the AirFree vent, position the bottle so the AirFree vent is pointing upwards. This ensures the nipple stays full of milk and air is drawn away from the baby's tummy.
- The unique valve in the nipple flexes to allow air into the bottle, preventing vacuum build-up, and keeping air away from your baby's tummy.
- The nipple is designed to allow milk to flow only at your baby's natural feeding rhythm, reducing overeating, spit-up, burping, and gas.
- Always check the temperature of the milk before feeding by dropping a few drops on the inside of your wrist.

6.2 Sterilization

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Baby experiences colic/fussiness. | Air intake during feeding. | Ensure the AirFree vent is used and positioned upwards during feeding. Check nipple flow rate is appropriate for baby's age. |
| Milk leaks from the bottle. | Nipple or screw ring not properly secured; damaged parts. | Ensure screw ring is tightened securely. Check nipple and screw ring for tears or damage and replace if necessary. |
| Nipple collapses during feeding. | Vacuum build-up; nipple flow rate too slow. | Ensure the AirFree vent is correctly assembled and positioned upwards. Consider using a nipple with a faster flow rate if your baby is struggling to feed. |
