Philips Avent Natural Baby Bottles Slow Flow 4 oz 4-Pack — Anti-Colic, BPA-Free

Philips Avent Natural 4 oz baby bottles are designed to let infants control milk flow, combining bottle and breastfeeding rhythms with a slow-flow nipple and integrated anti-colic valve.

These four 4-ounce Natural bottles from Philips Avent are built to support parents who want an easy, gentle transition between breast and bottle feeding. The wide, soft nipple shape mimics a breast-like feel while the unique valve system releases milk only when the baby actively drinks, helping preserve natural sucking patterns. Constructed of BPA-free polypropylene, each bottle is quick to fill, simple to clean and compatible with the Natural Response accessory range.

How does this bottle help my baby manage feeding pace?

The nipple opening only lets milk flow when your baby actively draws it, so pauses to breathe or swallow stop milk delivery immediately. This preserves the baby’s natural feeding rhythm and reduces overfeeding risks associated with continuous flow.

• Active-release nipple that responds to suction
• Slow-flow (Flow 2) tip suited for newborns and early months
• No-drip design to minimize milk loss during pauses
• Supports combined breastfeeding and bottle feeding routines

Will this bottle help reduce fussing or gas during feeds?

An integrated air-venting valve channels air away from the milk stream so less air reaches the baby’s stomach during feeding. That reduces gulping of air, which can lessen gassiness and feeding-related discomfort for some infants.

• Anti-colic valve built into the nipple to divert air
• Smooth internal flow prevents sudden gulps
• Compatibility with other Avent Natural nipples and caps
• Designed for gradual transition across nipple flow rates

How easy are these bottles to clean, assemble and carry?

The bottles feature a wide neck and a small number of parts so filling, washing and reassembling are straightforward. Lightweight polypropylene construction and a secure cap make them practical for home use or when you’re out with your baby.

• Wide bottleneck for easy pouring and cleaning
• Fewer components speed up assembly and drying
• BPA-free material is durable and travel-friendly
• Includes four bottles for rotation between uses

What sizes and accessories work with these Natural bottles?

The 4 oz bottle comes with a slow-flow nipple (Flow 2) and fits other Philips Avent Natural caps, nipples and covers. This modular compatibility lets parents adapt flow rates and closures as their baby grows.

• Includes four 4 oz bottles with Flow 2 nipples
• Works with other Natural series nipples and lids
• Switch to faster flow nipples as baby’s feedings evolve
• Interchangeable parts reduce need for multiple bottle types

Who is this for: Parents seeking a bottle that supports mixed breastfeeding and bottle feeding, prefers a breast-like nipple feel, and wants a slow, controllable milk flow to help baby set the feeding pace. Ideal for caregivers who value easy cleaning, BPA-free materials and proven pediatric and parent recommendations when building a feeding routine.
