Philips Avent Natural Response Baby Bottles Slow-Flow 4 oz 4-Pack — Breast-like Nipple & Anti-Colic Valve

Philips Avent Natural Response 4 oz bottles are designed to let baby control milk flow with a breast-like nipple and an anti-colic valve for easier combination feeding.

These 4-pack Natural Response bottles pair a wide, soft breast-shaped nipple with a unique responsive opening so milk only flows when your baby actively drinks. The slow-flow (Flow 2) nipple helps newborns and young infants manage pacing, while an integrated anti-colic valve directs air away from the feeding stream. Lightweight, ergonomic and compatible across the Natural Response range, these BPA-free polypropylene bottles simplify feeding, cleaning and switching between breast and bottle.

How does the Natural Response nipple support a breastfeeding routine?

The nipple’s shape and action are meant to mimic a breast so babies can maintain a familiar latch and sucking rhythm when offered a bottle. Because the opening releases milk only when the baby draws it, feeding feels less like an always-on drip and more like breastfeeding. This can help reduce confusion for babies learning both methods.

• Wide, soft, breast-shaped nipple encourages a natural latch.
• Responsive opening releases milk only during active sucking.
• Slow-flow nipple (Flow 2) helps newborns pace feeds.
• Compatible with other Natural Response nipples and caps for flexibility.

Will these bottles help reduce air intake and fussiness during feeds?

The built-in anti-colic valve is designed to channel air away from the milk path, so air doesn’t mix with the milk being swallowed. This helps maintain a steady flow and can reduce gurgling or excessive burping after feeds. The system is mechanical and part of the nipple, requiring no extra assembly.

• Integrated valve in the nipple directs air away from the milk stream.
• Valve works automatically as baby drinks; no additional parts needed.
• Helps make feeding quieter and reduces spitting for many infants.
• Easy to disassemble for routine cleaning to keep the valve working well.

How easy are these bottles to clean, hold and use every day?

The bottles have a wide neck to make pouring, filling and washing more straightforward, and there are only a few parts to assemble. The ergonomic profile is comfortable for adults to hold and also allows small hands to grasp the bottle as baby develops. Dishwasher-safe polypropylene and cross-compatible Natural Response components speed up daily maintenance.

• Wide bottle neck simplifies filling and manual cleaning.
• Few parts mean faster assembly and less to lose when out and about.
• Ergonomic shape good for parent and baby handling.
• BPA-free polypropylene is lightweight and dishwasher-safe.

Which flow is included and what feeding stages is it best for?

This pack includes four 4 oz bottles fitted with slow-flow nipples (Flow 2), intended for newborns and younger infants who need a gentler rate of milk delivery.

• Each pack contains 4 × 4 oz bottles with Flow 2 slow nipples.
• Slow flow suitable for newborns and infants developing feeding rhythm.
