Dr. Brown's Natural Flow Anti-Colic Wide-Neck Baby Bottles 9 oz — 4 Count, Level 1 Slow-Flow Vent

Dr. Brown's Natural Flow Options+ Wide-Neck bottles are anti-colic baby bottles with an internal vent system and slow-flow silicone nipples designed to reduce spit-up, burping and gas while supporting a natural latch.

These 9 oz / 270 mL wide-neck bottles come as a four-count set with Level 1 slow flow nipples, intended for newborn feeding and early months. The internal vent system supports vacuum-free feeding that mimics breastfeeding rhythm and helps stabilize milk flow. Constructed to be reusable and recyclable, the bottles are compatible with common cleaning and sterilizing methods and are BPA free.

How does the internal vent system help during feeds?

The built-in vent channels air away from the milk so baby ingests less air, which can reduce common feeding discomforts like spit-up and gas. The vacuum-free design also maintains a steady flow so baby controls the pace of feeding rather than being forced by pressure differences.

• Internal vent removes air from milk, reducing swallowed air
• Helps maintain consistent milk flow for calm, responsive feeds
• Can help reduce burping and spit-up episodes

Will these bottles support breastfeeding and bottle transitions?

The nipple shape is breast-like to encourage a natural latch pattern, making it easier to switch between breast and bottle. Because the vent system can be kept in place or removed as baby develops, caregivers avoid switching to a different bottle model as feeding needs change.

• Breast-like silicone nipple supports latch and familiar feeding motions
• Removable vent option lets the bottle adapt to developmental stages
• Consistent slow flow nipple encourages self-paced feeding

How do I clean and sterilize these wide-neck bottles safely?

Dr. Brown's bottles are made for everyday cleaning and fit the top rack of most dishwashers and common sterilizing methods. The materials tolerate boiling water, electric and microwave sterilizers, but following manufacturer instructions for disassembly and temperature limits preserves parts and longevity.

• Top-rack dishwasher safe for easy daily cleaning
• Compatible with electric and microwave sterilizers or boiling water
• Disassemble vent, collar and nipple to clean all components thoroughly

What environmental and safety features should I know about?

The bottles are BPA-free and designed to be recyclable, aligning with efforts to reduce single-use plastics. Dr. Brown's collaboration with Plastic Bank supports plastic collection initiatives to help prevent ocean plastic, reflecting a broader sustainability commitment.

• BPA-free materials for routine feeding safety
• Recyclable wide-neck bottles reduce long-term waste
• Partnership with Plastic Bank aims to offset ocean-bound plastic
