Philips Avent Anti‑Colic Baby Bottle 9 oz with AirFree Vent — Medium Flow, Wide Neck for Easier Upright Feeding

Philips Avent Anti‑Colic 9 oz baby bottle with the AirFree vent helps minimize swallowed air so babies can feed more comfortably upright.

These 9 oz bottles pair a soft, shaped silicone nipple with an integrated AirFree vent to keep the nipple filled with liquid rather than air. That design reduces the chance of babies ingesting air during feeds, which can help ease common feeding challenges such as gas, burping and reflux-related discomfort. The wide-neck bottle is straightforward to assemble and clean, and the vent can be used or removed depending on your baby’s preferences.

How does the AirFree vent reduce air ingestion during feeding?

The AirFree vent directs air away from the nipple so the teat remains full of milk even when the bottle is tilted. Because the nipple stays liquid-filled, babies draw in less air while sucking, which can lead to fewer gassy episodes and less fussiness after a feed.

• Vent keeps nipple full of milk rather than air
• Integrated valve in the nipple reduces vacuum buildup
• Works with the bottle held horizontally for upright feeds

Can I clean and assemble the bottle easily?

Yes — the bottle is designed with a wide neck and minimal parts to speed washing and reassembly. The AirFree vent is a single-piece element that does not require specialized brushes, and all components are dishwasher-safe on the top rack for convenience.

• Wide neck simplifies access for hand washing
• Single-piece vent reduces cleaning steps
• Few parts make assembly fast and intuitive

What flow and compatibility options are available?

The soft silicone nipple is offered in multiple flow rates so you can match feeding speed to your baby's age and appetite. The anti-colic bottle is compatible with Philips Avent anti-colic nipples and can be used with or without the AirFree vent depending on your baby’s needs.

• Medium flow (Flow 2) nipples included in this pack
• Nipple flows available in sizes 1–4 to grow with baby
• Interchangeable with other Philips Avent anti-colic nipples

Does upright feeding with this bottle help reflux and digestion?

Because the vent keeps the nipple filled while the bottle is tilted, caregivers can feed in a more upright position, which many parents find helps reduce reflux and supports swallowing. While individual results vary, feeding more upright can make burping and digestion easier for some infants.

• Upright feeding position supported by vent design
• May reduce backflow and ease digestion for some babies
• Helps maintain a steady milk flow during feeds

Who is this for: Parents and caregivers seeking a reliable anti‑colic feeding solution for infants who experience gas, frequent burping or reflux—especially those who want the option to feed more upright. This pack of four 9 oz bottles with medium-flow (Flow 2) nipples suits babies moving beyond newborn feeds and families who need multiple bottles ready between washes. If you prefer simple cleaning, interchangeable Philips Avent parts, and a vent that can be used or removed, these bottles offer flexible, everyday feeding support.
