Make sure to clean and sterilize all parts before use.
- Fill your Philips Avent Anti-colic bottle with milk
- Place the AirFree vent between the bottle and the nipple
- Fill the nipple by holding the bottle upside down
- Make sure the AirFree vent is faced upwards while feeding your baby, aligning the bottle with the nose of your baby (see image below)
Note: You can use the Philips Avent Anti-colic bottle without the AirFree vent
