Philips Avent Anti-Colic Baby Bottle, 4 oz with AirFree Vent — Slow-Flow Silicone Nipple, BPA-Free

This Philips Avent bottle is made for parents looking to minimize colic, gas and reflux concerns during early feeds. The integrated AirFree vent redirects air away from the nipple so the teat stays filled with milk even when the bottle is held horizontally. Together with the soft, slow-flow silicone nipple and an anti-colic valve, this system supports a calmer feeding experience and simpler cleaning for busy caregivers.

How does the AirFree vent change the way my baby drinks?

The AirFree vent routes air to the top of the bottle so the nipple remains filled with milk rather than air, which helps reduce the amount of air your baby swallows. Because the nipple stays full even when the bottle is tipped, you can feed in a more upright position that may be gentler for babies prone to reflux or spitting up. The vent is a single-piece design that snaps into the bottle and can be used or removed depending on your baby’s preference.

• Directs bubbles away from the nipple so baby swallows less air.
• Makes upright feeding easier by keeping the teat filled with milk.
• One-piece vent snaps in for simple assembly and cleaning.

Will this bottle fit my current Philips Avent nipples and parts?

The 4 oz Anti-Colic bottle is compatible with Philips Avent anti-colic nipples and other Avent bottle accessories designed for this range. Philips Avent recommends using their Anti-Colic nipples to maintain the valve function and feeding performance. You can mix and match flows (available in Flow 1–4) as your baby grows, and you can choose to use the bottle with or without the AirFree vent based on comfort and feeding style.

• Compatible with Philips Avent Anti-Colic nipples and most Avent parts in the same line.
• Nipples available in different flows to match developmental stages.
• Vent is removable so bottle works either way for flexibility.

How easy is cleaning and day-to-day care?

Cleaning is straightforward: the wide-neck design and minimal parts make washing and sterilizing quick. The AirFree vent is a single piece that does not require specialized tools to clean, and the slow-flow silicone nipple can be taken apart from the collar for routine washing. This simplicity helps save time between feeds and reduces the number of small components to track during busy days.

• Wide bottle neck allows easy access for brushes and sponges.
• One-piece vent and few bottle parts speed up cleaning and assembly.
• BPA-free materials for everyday safety and reassurance.

What feeding stage is the slow-flow nipple best for?

The included Flow 1 slow-flow nipple is designed for newborns (0 months+) and helps regulate milk flow for early feeding skills. As your baby grows and develops stronger sucking abilities, Philips Avent offers nipples in flows 2–4 to increase flow rate gradually. Using the appropriate flow can reduce choking or overfeeding and make transitions to faster flows more comfortable.

• Flow 1 recommended for newborns and first feeds.
• Upgrade to flows 2–4 as baby’s suction strength increases.
• Soft silicone nipple promotes natural latch and comfortable feeding.

Who is this for: Parents and caregivers seeking a straightforward, well-engineered feeding option for infants who experience colic-like symptoms, gas or reflux, or for anyone who prefers upright feeding. It's also suitable for families who already use Philips Avent products and want interchangeable parts, minimal cleaning complexity, and a slow-flow option for newborn feeding.
